Why Solana projects need professional audits
Solana’s account model, CPI patterns, and runtime constraints introduce risk classes that don’t map cleanly to EVM-style audits. A Solana audit needs reviewers who are fluent in Rust patterns and Solana-specific threat models.
2025 reality check
$4.0B was lost. $512.0M (12.8%) came from smart contract vulnerabilities, while $2.12B (53%) came from access-control failures.
Translation:
code still causes massive losses – but the biggest damage comes from broken authorization and key/control paths. That’s why our Solana audit focuses heavily on who can do what, under which constraints, and how funds move.
Critical Solana vulnerabilities we audit for (and why this matters)
Untrusted accounts & authority checks
We validate owner + signer requirements and critical account relationships so attackers can’t swap in look-alike “config/vault/user” accounts to take control.
Type cosplay & broken invariants
We confirm the right account type, expected addresses, and SPL account properties – especially where “bytes that deserialize” can become “funds that leave”.
CPI safety
We harden CPI call paths by verifying program IDs and constraining accounts – so your program can’t be tricked into authorizing attacker-controlled logic.
Math, precision & accounting edge cases
We test overflow/underflow, truncation, and rounding issues that can silently break balances, fees, or collateral logic.
Token authority & Token-2022 extension risks
We verify mint/burn/freeze/delegate controls, SPL account validation, and extension behaviors that can introduce unexpected privilege or transfer paths.
Upgrades, admin controls & migrations
We analyze upgrade paths, pausability, accounts model changes, and migration safety – code changes introduce a critical risk once real user funds are live.
What you get from a Hacken Solana smart contract audit
Prioritized findings your engineers can ship against
Clear severity, impact, and fix guidance – structured for fast triage and remediation.
Verifiable PoCs for High/Critical issues
For severe findings, we include exploit descriptions as verifiable scenarios so your team (and stakeholders) can understand real-world risk.
A report you can share with partners and exchanges
A clean audit narrative: scope, system overview, risks, findings, definitions, fuzz/invariant results if applied.
Remediation verification
You can submit in-scope remediations within two weeks; we re-check fixes, confirm they don't introduce new risks, and update statuses for the final report.
Real-time visibility in Hacken Portal
Track progress, collaborate with the team, and manage findings in one place with role-based involvement and live tracking.
Our Solana audit reports
Verifiable reports trusted by exchanges and partners:
Explicit scope, audited commits, changelog, and verified remediation steps.
"We work closely with you to define the scope, timeline, and budget that meet your specific needs and expectations. Then, we prepare the testing environment and unit tests to ensure an optimal process and maximum value."
2.1 Manual review with double coverage: auditors perform a simultaneous line-by-line review to reduce human error and improve consistency.
2.2 Automated scanning: static/dynamic tools complement the manual review and catch common patterns early.
2.3 Fuzz and invariant: fuzzing and invariant testing to uncover unexpected behaviors and broken rules.
3.1 Findings are recorded in a secure reporting portal and shared in real time, enabling early prioritization and remediation planning.
3.2 For High/Critical issues, the report includes exploit scenarios to make the impact verifiable.
4.1 After the initial report, we verify that fixes resolve the issues and don't introduce new risks, then publish a final comprehensive report.
4.2 A dedicated QA step validates severity accuracy, reproducibility, consistency, and completeness.
This step is optional and can be added after the audit if additional assurance is needed.
5.1 Extended security validation: combines a traditional audit with crowdsourced security testing to increase coverage beyond a single review cycle.
5.2 Real-world attack simulation: independent researchers test the system under live conditions to surface edge cases and overlooked attack paths.
5.3 Post-audit assurance: useful after fixes, upgrades, or before launch, listings, and external due diligence.
Hacken's Solana audit process
