Every audit follows a three-phase process: automated scanning with Slither, Mythril and Echidna for known vulnerability patterns; manual line-by-line review for business logic flaws, economic attack vectors and protocol-specific risks; and formal verification for high-value contracts where mathematical proof of correctness is warranted. Gas optimization runs in parallel with profiling tools measuring every function's execution cost.
Pharos Verified Delivery applied to 70+ production applications since 2013
Anonymized before/after snapshots from production projects. Metrics measured against client-reported pre-engagement baselines.
12,000 lines of Solidity across 34 contracts. Internal team ran Slither but had 180+ unreviewed findings. No formal threat model. Launch blocked by insurance underwriter requiring independent audit.
Full manual + automated audit completed in 3 weeks. 4 critical vulnerabilities identified including a reentrancy path in the liquidation function, 11 medium issues, 23 gas optimizations. All critical and medium issues remediated and re-verified. Insurance underwriter approved coverage. Protocol launched with $14M TVL in first month.
The reentrancy path was in the liquidation function, not the lending core - exactly the kind of cross-contract interaction that automated tools miss. Manual review caught it in hour 6 of the line-by-line pass.
Minting function cost 287,000 gas per token. At 50 gwei base fee each mint cost users $18.40. Drop of 10,000 NFTs projected $184,000 in total gas fees. Community backlash about mint costs on social media.
Refactored to ERC-721A batch minting, packed storage slots, removed redundant SLOAD operations, implemented bitmap-based allowlist. Gas per mint dropped to 62,000 (78% reduction). Per-mint cost at 50 gwei: $3.98. Total gas savings across 10,000-mint drop: $144,200.
The biggest single win was replacing the mapping-based allowlist with a bitmap. One storage slot holds 256 boolean flags instead of 256 separate slots - cutting allowlist verification from 20,000+ gas to under 800.
$890,000 drained through a signature replay attack. Team patched the immediate vector but lacked confidence in remaining codebase. TVL dropped 60% due to user trust loss.
Emergency audit completed in 5 business days. 2 additional critical vulnerabilities unrelated to the original exploit identified (oracle manipulation and insufficient access control on admin functions). Full remediation, re-audit and public report published. TVL recovered to 85% of pre-exploit level within 90 days.
We started with a 48-hour triage focused on the admin function surface area since the original exploit used a privileged path. The oracle manipulation finding came from the deeper structural review in days 3-5.
Client names anonymized under NDA. Full case studies at /cases/.
We decline roughly 30% of RFPs we receive. Forcing a bad fit costs both sides 3-6 months and damages outcomes. Here is how we think about scope:
A $5,000 automated scan and peer review covers 80% of risk for standard contracts. A full manual audit makes sense when custom logic, cross-contract interactions or significant TVL at stake justify the investment. We size the engagement to the actual risk profile, not to maximize billable hours.
Security audits are most effective when paired with well-architected contracts from day one. See how our smart contract engineering reduces audit findings before the first review.
Observations from 19 smart contract audit and gas optimisation engagements delivered 2021-2026 across DeFi, NFT, wallet and bridge protocols.
Protocols with invariant fuzz campaigns averaging 10M+ runs caught 2.7x more high-severity issues than audits without fuzzing in our sample.
Gas optimisation on L2-first protocols yielded diminishing returns; focus shifted to correctness and economic safety in 14 of 19 engagements.
On-chain monitoring (Forta or equivalent) detected anomalies in 3 of 4 tracked post-launch incidents before customer reports.
Teams of 2 to 3 senior auditors shipped full reports in 3 to 6 weeks depending on scope complexity.
An audited DeFi protocol launched in 2023 passed 2-firm audit with zero high-severity findings on the core. Six months post-launch, an attacker used a governance path (queue-and-execute a proxy upgrade) to install a malicious implementation that drained $1.8M over a single block. Root cause: audit scope covered core logic thoroughly but treated governance contracts as "well-understood OpenZeppelin pattern" and skipped deep review. We re-audited the governance layer with a third firm, tightened timelock parameters, added on-chain monitoring for any queued upgrade and shipped a voter-notification system. No further governance incidents in 18 months since. The lesson we apply: governance contracts are protocol-critical and audit scope must include them explicitly.

Standard audits for 1,000-5,000 lines of Solidity take 2-3 weeks. Complex DeFi protocols with cross-contract interactions and oracle dependencies take 4-6 weeks.
Emergency post-incident audits can start within 48 hours with preliminary findings in 5 business days. Timeline depends on codebase size, protocol complexity and whether formal verification is included.
Single-contract audits under 500 lines start at $8,000. Standard DeFi protocol audits (1,000-5,000 lines) range from $25,000 to $60,000.
Complex multi-protocol systems with formal verification run $80,000-$200,000+. Gas optimization as a standalone engagement starts at $5,000 per contract. Combined audit plus gas optimization is 15-20% less than booking separately.
Automated tools (Slither, Mythril, Echidna) detect known vulnerability patterns like reentrancy and integer overflow in minutes. They catch roughly half of issues by volume but miss business logic flaws and economic attack vectors.
Manual review catches the other half including the high-severity issues that require human reasoning about protocol-specific risks. A production audit requires both for coverage and depth.
Yes. We audit Solidity contracts on all EVM-compatible chains including Ethereum, Polygon, Arbitrum, Optimism, Base, BSC and Avalanche.
We also audit Rust-based contracts for Solana (Anchor framework) and CosmWasm. The audit methodology is chain-specific because each runtime has different gas models, storage patterns and attack surfaces.
A detailed audit report with every finding categorized by severity (critical, high, medium, low, informational), root cause analysis, proof-of-concept exploit code where applicable, recommended fix and verification status. Gas optimization deliverables include a before/after gas profile, refactored contract code and a gas savings summary per function.
All findings are tracked until remediation is verified.
