What to Look for in a Solana Audit Firm
Solana-specific experience. How many Solana programs have they audited? Do they understand Anchor and native Rust patterns?
Manual review depth. Automated tools catch known patterns. They miss logic errors and protocol-specific flaws. The best audits combine tooling with manual review.
Track record. Have they audited protocols that went to mainnet without exploits? Have they found issues in code other firms already reviewed?
Communication quality. Findings should be written for builders. Clear severity ratings, reproduction steps, practical fixes.
Timeline and availability. Some firms have two-month waitlists. Others can start sooner. If you're working toward a launch date, ask about availability upfront.
6. Sec3
Sec3 built some of the first automated security tooling specifically for Solana. Their X-ray scanner detects 50+ vulnerability types and integrates with GitHub CI, catching issues during development.
Beyond scanning, they offer manual audits and post-deployment monitoring through WatchTower. Their strength is tooling-first security that fits into your development workflow.
Good fit for: Teams that want continuous automated scanning alongside manual review.
5. Halborn
Halborn is one of the larger blockchain security firms globally. They operate across EVM and non-EVM chains with a dedicated Rust team. They've completed 40+ Solana audits, including work on SPL Token 2022 with Solana Labs.
Their strength is broad coverage: smart contract audits, penetration testing, and infrastructure assessments from a single vendor.
Good fit for: Multi-chain teams who want one security partner across all deployments.
4. Certora
Certora specializes in formal verification, using mathematical proofs to guarantee that code behaves as specified. Their Solana Prover analyzes SBF bytecode directly, verifying the actual program that runs on-chain.
Formal verification catches edge cases that testing and manual review miss. Most teams use Certora alongside a traditional audit rather than as a replacement.
Good fit for: DeFi protocols that need mathematical guarantees on critical code paths.
3. Accretion
Accretion focuses exclusively on Solana. No EVM work. No other chains. They've found critical vulnerabilities in a significant portion of previously audited protocols they've reviewed.
They operate at boutique scale with deep runtime expertise.
Good fit for: Solana-native protocols that want focused manual review from specialists.
2. OtterSec
OtterSec is one of the most established names in Solana security. They've audited Solana's core code, Wormhole, Jito Labs, Jupiter, and Raydium. They pioneered formal verification techniques for Solana programs and maintain active security research.
Lead times and pricing reflect their reputation and demand.
Good fit for: High-profile protocols/chains that want a well-known name and have timeline flexibility.
1. Adevar Labs
We focus on Solana and work with teams at different stages, from bootstrapped startups to Series A protocols.
Services:
- Manual smart contract audits with line-by-line review
- Custom fuzzing harnesses built for your specific protocol logic
- Formal verification for critical invariants
- Infrastructure audits covering cloud configurations, CI/CD, and key management
- Penetration testing for web apps, APIs, and off-chain components
How we work:
We use a hybrid model combining an in-house team with a vetted network of independent auditors. This helps us stay flexible on timelines and scope engagements for different budgets without cutting depth.
We typically start engagements within two weeks. We stay involved through fix verification.
100+ web3 audits across Solana, Sui, Ethereum, and other ecosystems.
Teams we've worked with: LI.FI, DoubleZero, Loopscale, GLAM, Moto, Carrot, star.fun, TREPA, Pact Labs, M0 Labs.
Good fit for: Teams who want Solana expertise, reasonable timelines, and straightforward communication.
How to Choose
Timeline. If you have two to three months, you have more options. If you need to start soon, ask about availability first.
Complexity. A token contract has different needs than a lending protocol with oracle integrations. Match the firm's depth to your risk profile.
Budget. Pricing varies significantly. Get quotes from a few firms and understand what's included.
Scope. Some teams need infrastructure assessment or formal verification. Others just need code review. Match capabilities to requirements.
After the Audit
Fix verification. Confirm issues are resolved before deploying.
Bug bounties. Platforms like Immunefi incentivize researchers to find what auditors missed.
Monitoring. Post-deployment alerts on suspicious activity limit damage from exploits.
Ongoing review. Code changes introduce risk. Significant updates warrant another look.
