Introduction

Purpose of This Methodology

The Deployment Audit for Solana Programs methodology addresses a critical but often overlooked phase in the blockchain development lifecycle: the transition from audited code to production deployment. While program code assessments verify the security and correctness of program logic, deployment audits ensure that programs are deployed, configured, and initialized correctly on-chain.

A deployment audit validates that:

  • Deployment automation is robust, repeatable, and fail-safe.
  • Programs are initialized with correct parameters and in the proper sequence.
  • Program upgradeability and upgrade authority are configured securely.
  • Account dependencies (PDAs), cross-program invocations, external integrations, and authorities are wired correctly.
  • Operational security practices protect deployment keypairs and sensitive configuration.
  • Post-deployment state matches intended specifications and security invariants.

This document is designed to present the methodology to development teams, DevOps engineers, and security professionals who manage the deployment of complex program systems on Solana.

When is a Deployment Audit Needed?

Deployment audits are essential for projects that:

  • Deploy multiple interconnected programs with complex initialization sequences.
  • Rely on upgradeable programs and must manage upgrade authority securely over time.
  • Integrate with external programs, oracles, DEXes, or governance systems through cross-program invocations.
  • Require precise authority configuration for programs, token mints, and PDA-owned accounts.
  • Operate in high-value or high-risk environments where deployment errors could result in loss of funds or system compromise.
  • Need reproducible, verifiable deployments for compliance or auditability.

Service Delivery Model

Hacken offers Deployment Audits as:

  • Standalone Service: For teams who have already completed a program assessment and need focused deployment review.
  • Add-on to Smart Contract Assessment: As an integrated extension of a comprehensive program security audit, ensuring end-to-end security from code to deployment.

Timeline: Deployment audits typically require up to 1 week depending on system complexity and scope.

Deliverable: A comprehensive Deployment Audit Report detailing findings, risks, and actionable recommendations.


Alignment with International Standards

Hacken's Deployment Audit Methodology aligns with established security and deployment frameworks, including:

  • NIST SP 800-115 – Technical Guide for Information Security Testing and Assessment.
  • NIST SSDF (Secure Software Development Framework) – Practices for secure software supply chain and deployment.
  • OWASP Code Review Guide – Ensuring structured code review principles.

This methodology ensures that deployment processes are consistent, auditable, and resilient against misconfigurations, operational errors, and adversarial attacks.


Part 1. Understanding Deployment Audits

What is a Deployment Audit?

A Deployment Audit is a systematic review of the deployment process and infrastructure for program systems on Solana. It evaluates:

  • The automation and scripts used to build and deploy programs.
  • The correctness of initialization instruction parameters and account inputs.
  • The setup of program upgradeability and upgrade authority.
  • The wiring of PDAs, account dependencies, cross-program invocations, and external integrations.
  • The configuration of authorities, permissions, and access controls.
  • The security of environment variables, keypair files, and deployment credentials.
  • The verification and reproducibility of deployed program bytecode.
  • The post-deployment validation of on-chain account state and invariants.
  • The operational scripts and procedures for ongoing maintenance and upgrades.

Unlike a program code audit, which focuses on instruction logic, a deployment audit focuses on how programs and on-chain state are deployed and configured in production.

What Counts as a Deployment on Solana?

Solana's account and program model makes "deployment" broader and often lighter-weight than on EVM chains. Deployment work on Solana falls on a spectrum, and a given project may involve one or both of the following scenarios:

  • Scenario A: Custom Program Deployment. The project ships its own on-chain program (Anchor, native Rust, or Pinocchio). This requires uploading BPF bytecode through the BPF Loader Upgradeable, managing buffer accounts, and configuring an upgrade authority. All of Phase 2's program-specific focus areas (2.1 through 2.3) apply here.
  • Scenario B: Configuration-Only Deployment. The project deploys no custom program at all. Instead, it stands up its on-chain footprint entirely through scripts that send instructions to existing, already-deployed programs (SPL Token, Token-2022, Metaplex, Squads, governance programs, AMMs, and so on). Here, "deployment" means creating and configuring accounts, mints, PDAs, and authorities, not uploading bytecode. Program-upload and upgrade-authority focus areas do not apply, while account creation, authority configuration, wiring, and post-deployment validation remain fully in scope.

Two consequences follow that this methodology treats explicitly:

  • There is no token deployment on Solana. A project does not deploy a token contract. To create a token, it sends an instruction (e.g., InitializeMint) to the existing SPL Token or Token-2022 program, which creates a mint account. Token creation is therefore an account-creation and authority-configuration activity reviewed under Phase 2.4, 2.5, and Phase 3, not a program deployment. The security focus is on mint/freeze authority assignment, decimals, initial supply, metadata, and Token-2022 extension authorities, not on any deployed bytecode.
  • Significantly large amount of Solana projects do not deploy a program. Many production launches are fully covered by Scenario B: setup scripts that create mints, config accounts, PDAs, associated token accounts, and multisig-controlled authorities using existing programs. The audit adapts to what the project actually deploys. When there is no custom program, the program-deployment and upgrade-authority sections are marked not applicable in the report, and effort concentrates on the setup scripts, account and authority configuration, and post-deployment on-chain validation.

During scoping (Phase 1), the applicable scenario is determined per program and per script so the report only assesses what is genuinely deployed.

Why is a Deployment Audit Critical?

Even perfectly audited program code can fail catastrophically if deployed incorrectly. Common deployment risks include:

  • Initialization Errors: Incorrect initialization parameters or account inputs can lock funds, misconfigure governance, or expose privileged instructions.
  • Upgrade Authority Misconfiguration: An upgrade authority left with a single deployer keypair, or set incorrectly, can allow unauthorized program upgrades that replace the entire program logic.
  • PDA and Account Wiring Failures: Wrong seeds, program IDs, or account addresses for oracles, treasuries, or external programs can lead to loss of funds or system failure.
  • Authority Misconfigurations: Incorrect mint/freeze authorities, missing multisig setup, or overly broad privileges create attack surfaces.
  • Secrets Exposure: Leaked keypair files, API credentials, or RPC endpoints can compromise deployment integrity and program control.
  • Non-Reproducible Deployments: Inability to verify deployed program bytecode against source code undermines trust and auditability.
  • Unvalidated State: Deploying without post-deployment checks can leave programs and accounts in insecure or inconsistent states.

A deployment audit mitigates these risks by validating every step of the deployment lifecycle.

Who Benefits from a Deployment Audit?

  • Development Teams: Gain confidence that deployment scripts and processes are secure and production-ready.
  • DevOps Engineers: Identify operational security gaps and improve deployment automation.
  • Security Teams: Ensure the deployment phase does not introduce vulnerabilities or undermine audit guarantees.
  • Project Stakeholders: Reduce deployment-related risks and protect user funds and reputation.
  • Auditors and Compliance Officers: Verify that deployment processes meet security and regulatory standards.

Part 2. Deployment Audit Methodology Phases

The Deployment Audit process consists of the following phases:

  1. Scoping and Preparation
  2. Program Deployment Script Analysis
  3. Configuration and Initialization Review
  4. Operational Scripts and Runbooks
  5. Reporting and Recommendations

Phase 1: Scoping and Preparation

Objective: Define the audit scope, gather deployment artifacts, and establish success criteria.

Activities:

  • Scope Definition: Identify target cluster(s), deployment environment (mainnet-beta, devnet, testnet), and programs in scope.
  • Scenario Determination: For each program and each script, determine whether the work is a custom program deployment (Scenario A) or a configuration-only deployment against existing programs (Scenario B). This decides which Phase 2 focus areas apply and which are marked not applicable.
  • Artifact Collection: Collect deployment scripts, configuration files, environment setups, and documentation.
    • Setup and configuration scripts that create mints, accounts, PDAs, and authorities against existing programs (TypeScript/@solana/web3.js, Anchor client, or shell using the Solana CLI), applicable to both scenarios
    • Anchor deployment configuration and scripts, applicable when a custom program is deployed (Anchor.toml, migrations/, TypeScript deploy scripts)
    • Native solana program deploy scripts and shell tooling, applicable when a custom program is deployed
    • Program keypairs and derived program IDs, when a custom program is deployed (public keys only for scope, never private material)
    • Configuration files (.env, Anchor.toml, Cargo.toml, solana config, cluster and RPC settings)
    • Deployment logs, transaction signatures, and buffer account records (if already deployed)
    • Upgrade authority and multisig (e.g., Squads) documentation
    • Authority and permission specifications (upgrade, mint, freeze, admin PDAs, Token-2022 extension authorities)
    • Token and mint specifications (mint addresses, decimals, initial supply, metadata, extensions)
    • IDL files and the intended IDL publishing/upgrade authority, when a custom Anchor program is deployed
  • Context Gathering: Understand deployment architecture, PDA layouts, cross-program dependencies, and operational requirements.
  • Success Criteria: Define expected post-deployment state, critical invariants, and validation checkpoints.

Deliverables:

  • Scoping document with audit boundaries and objectives.
  • Checklist of required artifacts and documentation.

Phase 2: Deployment Script Analysis

Objective: Evaluate the security, robustness, and reliability of deployment automation scripts, whether they upload a custom program (Scenario A) or configure on-chain state against existing programs (Scenario B).

Applicability: Focus areas 2.1 through 2.3 apply only to custom program deployments (Scenario A) and are marked not applicable when the project deploys no program. Focus areas 2.4 through 2.8 apply to both scenarios, since account creation, authority configuration, wiring, secrets handling, ordering, and multi-cluster concerns are present even when only existing programs are used. Token and mint creation, being an instruction to an existing program rather than a deployment, is assessed under 2.4 and 2.5.

Key Focus Areas:

2.1 Deployment Scripts and Automation

  • Framework Compatibility: Review scripts for correct use of the Anchor CLI (anchor build, anchor deploy), the Solana CLI (solana program deploy), or custom deployment tooling (native Rust, Pinocchio).
  • Buffer and Chunked Deployment: Verify correct handling of buffer accounts used to upload program data in chunks, including cleanup of buffers after a successful deploy and recovery of partially uploaded buffers after failures.
  • Transaction Sizing and Compute Budget: Ensure deployment and initialization transactions respect transaction size limits, use appropriate compute budget instructions, and set adequate priority fees to land during congestion.
  • Idempotency: Verify that scripts can safely resume after failures without causing duplicate deployments, orphaned buffer accounts, or inconsistent state.
  • Failure Handling: Check for error handling, retry logic, and recovery procedures (e.g., resuming an interrupted deploy with the same buffer) in case of deployment failures.
  • Program Keypair Handling: Confirm the program keypair is generated, stored, and referenced correctly, and that the resulting program ID matches all declare_id! values and client configuration.
  • Cluster Targeting: Ensure the active solana config cluster and RPC endpoint match the intended deployment target to prevent accidental cross-cluster deploys.

2.2 Initialization Instruction Correctness

  • Parameter Validation: Verify that initialization instruction arguments are correct, validated, and match specifications.
  • Initialization Order: Ensure programs and their state accounts are initialized in the correct sequence to avoid dependency issues (e.g., config account before dependent PDAs).
  • PDA Derivation and Seeds: Confirm that PDA seeds, bumps, and program IDs used during initialization match the on-chain program logic, and that canonical bumps are used consistently.
  • Rent Exemption and Account Sizing: Verify that initialized accounts are allocated the correct space and funded to rent-exemption, and that account size matches the serialized data layout.
  • Setup Guarantees: Confirm that all required setup steps (e.g., assigning authorities, creating token mints, writing config) are completed.
  • Uninitialized Account Prevention: Check for protections against leaving state accounts uninitialized or partially initialized, and correct use of init versus init_if_needed where applicable.

2.3 Program Upgradeability and Upgrade Authority

  • Loader Selection: Verify the program is deployed under the BPF Loader Upgradeable when upgradeability is required, or confirm immutability is intentional when the upgrade authority is set to none.
  • Program Data Account: Confirm the program data account (ProgramData) is correctly associated with the program account and holds the expected upgrade authority.
  • Upgrade Authority Wiring: Ensure the upgrade authority is set to a secure controller (e.g., a Squads multisig or governance PDA) rather than a single deployer keypair.
  • Buffer Authority: Validate that buffer accounts used for staging upgrades have their authority set correctly and cannot be hijacked by a third party before the upgrade completes.
  • Immutability Decisions: Confirm whether the program is intended to be made immutable, and if so, that authority removal is deliberate, documented, and irreversible-by-design considerations are understood.
  • Upgrade Controls: Verify that program upgrades can only be executed through the intended authority and process (e.g., multisig approval), and that no alternative path can replace program bytecode.
  • IDL Authority (Anchor): For Anchor programs, verify that the on-chain IDL account authority is controlled appropriately and that IDL upgrades follow the same governance as program upgrades.

2.4 Account Wiring and Dependency Configuration

  • PDA Linkage: Ensure all inter-program dependencies are correctly wired through PDAs and expected account addresses (e.g., a config PDA referenced by dependent instructions).
  • Cross-Program Invocation (CPI) Targets: Verify that program IDs used as CPI targets are correct and pinned, and that no CPI relies on an unverified or attacker-controllable program.
  • External Integrations: Verify correct program IDs and account addresses for external protocols, oracles (e.g., Pyth, Switchboard), DEXes/AMMs, and bridges.
  • Registry and Config Accounts: Confirm correct creation and registration of global config, registry, or state accounts.
  • Token and Mint Creation: Confirm that token creation is performed correctly as an instruction to the existing SPL Token or Token-2022 program (e.g., create the mint account, then InitializeMint), not as a program deployment. Verify decimals, initial supply, mint/freeze authority, and any metadata are set as specified at creation time.
  • Token Program Selection: Confirm the correct token program is used (SPL Token vs Token-2022), that the mint is created under the intended program, and that associated token accounts are derived and created correctly.
  • Multisig and Governance Addresses: Validate that multisig (e.g., Squads), DAO, or governance program addresses and PDAs are accurate.
  • Treasury and Admin Addresses: Ensure treasury, fee recipient, and admin authorities are correctly configured.

2.5 Authorities and Access Model

  • Upgrade Authority Transfer: Verify that upgrade authority is transferred to a multisig, governance program, or secure controller (not left with the deployer keypair).
  • Multisig Setup: Ensure multisig controllers (e.g., Squads) are properly configured with correct members, thresholds, and any time delays.
  • Admin and Config Authorities: Confirm that on-chain admin authorities stored in config accounts or PDAs are assigned correctly and enforce the intended access model.
  • SPL Token Authorities: Validate mint authority and freeze authority configuration on token mints, and confirm they are set to the intended controller or revoked (set to none) where required.
  • Token-2022 Extensions: For Token-2022 mints, review extension authorities (e.g., transfer fee config authority, transfer hook authority, permanent delegate, metadata pointer/update authority, close authority) and confirm each is configured as intended.
  • PDA-Owned Accounts: Ensure accounts that should be owned and controlled by a program PDA are not controllable by an external keypair.
  • Separation of Duties: Ensure appropriate separation of duties and least-privilege principles are applied across authorities.

2.6 Environment and Secrets Handling

  • RPC Configuration: Review RPC endpoint configuration for security, reliability, and fallback options, including rate-limit handling for large program uploads.
  • Deployer Keypair Management: Assess security of deployer and upgrade authority keypairs (e.g., hardware wallet, secure key management, or multisig-controlled signing).
  • Keypair File Handling: Ensure keypair JSON files (program keypair, deployer keypair) are not committed to source control and are stored and referenced securely.
  • Environment Variables: Ensure sensitive data (keypairs, API credentials, RPC URLs) are not hardcoded and are properly managed (e.g., .env files excluded from version control, secret management tools).
  • CI/CD Integration: Evaluate security of deployment pipelines and secret handling in CI/CD environments, including how signing keys are injected.
  • Operational Security: Assess overall operational security practices around building, signing, broadcasting, and managing deployments and upgrades.

2.7 Transaction Ordering and Front-Running Protection

  • Initialization Front-Running: Verify that global initialization instructions and one-time-setup PDAs cannot be front-run by an attacker to claim authority or set malicious parameters before the legitimate deployer, especially for permissionless initialize instructions.
  • Deploy-to-Initialize Gap: Assess the window between program deployment and initialization, and evaluate whether deployment and initialization can be bundled or otherwise protected so that no attacker can invoke privileged setup instructions first.
  • PDA Squatting: Confirm that critical PDAs are derived from program-controlled seeds so that no external party can pre-create or squat on the expected addresses.
  • Priority Fees and Landing Guarantees: Review the use of priority fees and compute budget settings to ensure critical deployment and initialization transactions land reliably during network congestion.
  • Atomic Setup Patterns: Evaluate whether multi-step setup uses atomic transactions or a single controlling instruction where feasible, eliminating intermediate vulnerable states.
  • Address Lookup Tables (ALTs): For deployments relying on Address Lookup Tables, verify that tables are created and populated with the correct addresses and that their authorities are managed securely.
  • Time-Sensitive Operations: Review handling of time-sensitive initialization parameters (epoch or slot-based schedules, oracle staleness thresholds, vesting start times) to ensure deployment timing aligns with protocol requirements.

2.8 Multi-Cluster and Cross-Chain Considerations

  • Program ID Consistency: When deploying to multiple clusters (devnet, testnet, mainnet-beta), validate whether the same program ID is required across clusters and that declare_id! and client configuration match the target cluster.
  • Cluster-Specific Addresses: Verify that external protocol program IDs and account addresses (oracles, DEXes, bridges, token mints) are correctly configured per cluster and not accidentally using devnet addresses on mainnet-beta or vice versa.
  • Feature Activation Differences: Assess whether program behavior depends on runtime features that may be activated on some clusters but not others, and confirm compatibility with the target cluster's active feature set.
  • Cluster Version and Compute Limits: Review compatibility with the target cluster's validator version and compute budget defaults, and confirm the program builds against a compatible Solana toolchain.
  • Deployment Ordering Across Programs: For protocols spanning multiple programs, define and validate the correct deployment sequence and cross-program initialization order.
  • Cross-Chain Messaging: For deployments involving cross-chain messaging (e.g., Wormhole, LayerZero), account for message propagation delays, guardian or relayer trust assumptions, and correct configuration of foreign chain identifiers and emitter addresses.
  • Cluster Selection Validation: Ensure deployment scripts validate the active cluster and RPC endpoint before execution to prevent accidental deployment to an unintended network.
  • RPC Endpoint Reliability: Evaluate RPC endpoint configuration per cluster, including fallback providers and rate limiting considerations for large program deployments.

Phase 3: Configuration and Initialization Review

Objective: Validate that all configuration values, initialization parameters, and on-chain setup are correct and secure.

Key Focus Areas:

3.1 Verifiable Builds and Reproducibility

  • Verifiable Build Matching: Verify that the deployed program bytecode matches the source code using verifiable build tooling (e.g., solana-verify, Anchor verifiable builds), producing a reproducible hash from the audited source.
  • Verified Build Registration: Confirm that the program is registered with a verified builds registry so third parties can independently confirm source-to-bytecode correspondence.
  • Toolchain and Build Settings: Validate the Rust and Solana toolchain versions, Anchor version, and build configuration used to produce the deployed artifact.
  • IDL Correctness: For Anchor programs, confirm the published on-chain IDL matches the deployed program and the audited source.
  • Reproducible Builds: Ensure the deployment can be reproduced deterministically (e.g., containerized builds) for auditability.

3.2 Post-Deployment On-Chain Validation

  • Deployed State Inspection: Review actual on-chain state of deployed programs and their state accounts.
  • Account Data Values: Validate critical account fields (e.g., admin authority, config parameters, paused flags, supply values).
  • Authority Assignments: Confirm that upgrade authority, mint/freeze authorities, and admin authorities are correctly assigned on-chain.
  • Program Data and Upgrade Authority: Verify the program data account's upgrade authority matches the intended controller.
  • PDA Verification: Confirm that critical PDAs exist, are owned by the correct program, and hold the expected data.
  • Program Correctness: Ensure the on-chain program bytecode corresponds to the intended, audited version (not a stale or incorrect build).
  • Critical Invariants: Validate that critical security and business invariants hold post-deployment.
  • Event and Log Emission: Check that expected initialization and setup logs or events (e.g., Anchor events) were emitted correctly.

3.3 Post-Deployment Authority and Key Cleanup

  • Deployer Keypair Privilege Revocation: Verify that the deployer keypair has no residual upgrade authority, admin authority, or privileged roles after deployment completes.
  • Upgrade Authority Handover: Confirm the program upgrade authority has been transferred to the intended multisig (e.g., Squads), governance program, or set to none for immutability, and that the deployer cannot reclaim it.
  • Intermediate Authority Audit: Confirm that any intermediate authorities used during deployment (temporary admins, setup keypairs) have been stripped of all elevated permissions.
  • Buffer Account Cleanup: Verify that leftover buffer accounts from program deployment or upgrades have been closed and their rent reclaimed, and that no dangling buffer with a residual authority remains.
  • Token Authority Cleanup: Validate that mint and freeze authorities (and Token-2022 extension authorities) are set to the intended controller or revoked where the design requires fixed supply or no freeze capability.
  • IDL Authority Handover: For Anchor programs, confirm the on-chain IDL authority is transferred to the intended controller and not left with the deployer.
  • Deployer Wallet Fund Sweep: Ensure deployer wallets have been swept of remaining lamports where appropriate to minimize attack surface.
  • Key Rotation and Retirement: Confirm that deployment keypairs are rotated or securely retired after deployment, especially for high-value production deployments.
  • Access Control Completeness: Perform a comprehensive scan of all authority-gated instructions to ensure no instruction remains callable exclusively by the deployer keypair.
  • Emergency Recovery Paths: Document and validate any intentional residual authorities (e.g., emergency multisig) and confirm they are secured appropriately.

Phase 4: Operational Scripts and Runbooks

Objective: Ensure that operational procedures, upgrade scripts, and emergency actions are secure and well-documented.

Key Focus Areas:

4.1 Configuration Scripts

  • Parameter Updates: Review scripts for updating configuration parameters (e.g., fees, limits, authorities, referenced addresses).
  • Safe Execution: Ensure configuration scripts include validation and sanity checks, and that privileged updates route through the intended authority.

4.2 Upgrade Procedures

  • Upgrade Scripts: Validate program upgrade scripts, including buffer staging, upgrade authority signing (multisig flow), and IDL updates.
  • Testing and Validation: Confirm that upgrades are tested on devnet or a local validator before mainnet-beta execution, and that verifiable build hashes are checked before upgrading.
  • Rollback Plans: Check for rollback or recovery procedures in case of failed or faulty upgrades, acknowledging Solana's forward-only upgrade model (redeploy of a corrected build).

4.3 Emergency Actions

  • Pause/Halt Procedures: Review emergency pause or halt instructions and scripts where the program supports them.
  • Access and Authorization: Ensure emergency actions are only executable by authorized parties (e.g., multisig or emergency authority).
  • Incident Response: Assess documentation and procedures for incident response and emergency actions.

4.4 Routine Admin Procedures

  • Fee and Treasury Management: Review scripts for fee collection or treasury operations.
  • Authority Management: Validate procedures for granting, transferring, or revoking authorities.
  • Rent and Account Management: Review procedures for creating, resizing, or closing accounts and reclaiming rent safely.
  • Monitoring and Alerts: Assess operational monitoring and alerting mechanisms (e.g., authority changes, upgrade events, unusual instruction activity).

Phase 5: Reporting and Recommendations

Objective: Deliver a comprehensive Deployment Audit Report with findings, risk assessments, and actionable recommendations.

Deliverables

  • Deployment Audit Report: Comprehensive report with findings, risk assessments, and recommendations.
  • Remediation Guidance: Detailed instructions for addressing identified issues.
  • Post-Deployment Validation Results: Summary of on-chain state verification and invariant checks.

Limitations

  • Scope Boundaries: The deployment audit focuses on deployment processes, configuration, and initialization. It does not replace a program code assessment.
  • Network Conditions: Deployment audits assume normal network conditions. Extreme congestion, priority fee spikes, or cluster instability are outside the scope.
  • Third-Party Dependencies: The audit evaluates wiring and integration with external programs but does not audit the security of external programs themselves.
  • Future Changes: Recommendations are based on current deployment artifacts and configuration. Future changes to deployment scripts or infrastructure require re-evaluation.
  • Operational Assumptions: The audit assumes deployment keypairs and operational procedures are managed according to specified security policies. Actual operational execution is the responsibility of the client.
