Explore Gas Optimization and Cost-Reduction EngineeringWe utilize mathematical proofs and property-based testing to verify that a contract's behavior matches its intended specifications. This method ensures maximum reliability and correctness.
Explore Formal Verification and Specification TestingWe perform simulations of real-world attacks on your dApps, wallets and blockchain infrastructure to identify critical security weaknesses. Our testing boosts system resilience across front-end, back-end and smart contracts.
Explore Penetration Testing for Web3 ApplicationsWe deploy real-time on-chain monitoring systems that detect suspicious activity, contract anomalies and governance changes. Our alerts enable teams to respond quickly and prevent potential exploits.
Explore Continuous Security Monitoring and AlertingWe guide projects using best practices for regulatory compliance, secure architecture and risk mitigation. Our consulting helps teams launch safely while maintaining a long-term security posture.
Explore Compliance and Blockchain Security ConsultingAutomated tools catch 40-60% of issues by volume but miss business logic flaws and economic attack vectors. Manual review catches the remaining 40-60%, including the high-severity issues that automated tools cannot reason about. A production audit requires both.

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 110+ 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.
Audit practice in 2026 is moving from one-off "pre-launch check" to continuous security pipeline: formal verification on critical paths, fuzzing as part of CI, on-chain monitoring for post-deploy anomalies and mandatory 2-firm audits for any protocol handling public assets. Gas optimisation remains a deployment-day lever but L2 adoption has reduced its competitive value.
Trail of Bits and OpenZeppelin publish growing catalogues of exploit post-mortems; new attack vectors emerge monthly, making one-shot audits insufficient for living protocols[6][4].
Consensys Smart Contract Best Practices is updated quarterly; formal verification tools (Certora, Halmos) are now mainstream for critical DeFi primitives[3].
L2Beat data shows over 80 percent of new protocol deploys on L2s, lowering per-transaction gas pressure and shifting audit emphasis from optimisation to correctness[9].
Hardhat, Foundry and Echidna form the de facto fuzzing and invariant-testing stack; audits without documented invariants are a red flag[11].
Before accepting an audit report as closing condition for public launch, run this 8-point check against the report itself, not just the issues list.
Two independent firms have delivered public reports; findings cross-reviewed and remediated.
Scope covers all contracts deployed to mainnet, including upgrade paths, not just core logic.
Protocol-critical invariants defined and tested with Foundry or Echidna fuzz campaigns of at least 10M runs[11].
Report includes economic attack vectors (oracle manipulation, flash loan, MEV) not only code-level bugs[6].
Proxy pattern, storage collision risks and governance attack surface explicitly analysed.
Gas snapshot committed; per-function cost comparison provided for critical paths.
All high and critical findings re-tested after fix; report includes post-remediation sign-off.
On-chain monitoring (Forta, Tenderly) configured with alerts for key state deviations.
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.

A Pharos audit covers full static and manual analysis of your Solidity or Rust code - scanning for reentrancy, integer overflow, access-control flaws, logic errors and known attack vectors. We run Slither and Mythril for automated detection, then layer manual expert review on top to catch business-logic vulnerabilities automated tools miss. You receive a severity-ranked report with remediation guidance.
Timeline depends on contract complexity and line count. A single-contract DeFi protocol typically takes 5 to 10 business days; a multi-contract system with governance, staking and upgradeable proxies runs 2 to 4 weeks.
We share a preliminary findings draft at the halfway point so your team can begin remediation before the final report.
Gas optimization rewrites high-cost operations - storage writes, loops and redundant computations - to consume fewer gas units per transaction. Depending on original contract design, we typically reduce per-transaction gas by 15 to 40 percent. Savings compound at scale: a protocol processing 10,000 transactions per day can recover hundreds of thousands of dollars annually.
We use Slither for control-flow and data-flow analysis, Mythril for symbolic execution and integer-overflow detection and Echidna for property-based fuzz testing. Automated passes run first; manual expert review follows to eliminate false positives and surface vulnerabilities that require business-context understanding to identify.
Findings are classified as Critical, High, Medium, Low or Informational. Critical and High issues represent exploitable vulnerabilities that must be resolved before deployment.
Medium findings carry conditional risk. Low and Informational items are best-practice improvements. Each finding includes a description, proof-of-concept scenario, CVSS-aligned score and a concrete fix recommendation.
Yes. Every engagement includes one complimentary re-audit pass covering the findings listed in the original report.
We verify that remediations are correct and have not introduced secondary issues. If your team implements significant new logic during the fix cycle, that scope is scoped separately to ensure full coverage.
Yes. Post-deployment audits review live bytecode alongside source code and examine on-chain transaction history for anomalous patterns.
We also assess upgradeability risk if you use a proxy pattern. Findings inform an upgrade or migration plan that minimizes user disruption and preserves TVL during the remediation window.
