Solidity audits by people who write exploits in Foundry for a living.

We start by building the project locally and running your test suite, because an audit of code that does not compile the way the team thinks it does is worthless. We then read every contract in scope — not a sample — with the storage layout, inheritance graph and external call graph drawn out next to us. Tooling runs in parallel: Slither for pattern detection, Foundry invariant tests and Echidna for property fuzzing. Tool output is triaged by the same engineer doing the manual review, so you never receive a false positive dressed up as a finding.

Beyond the classics — reentrancy, access control, integer issues — the findings that keep appearing in 2026 post-mortems are subtler: precision loss that becomes exploitable at scale, first-depositor share inflation in vaults, storage collisions after an upgrade, signature replay across chains that share an address, oracle reads that can be moved inside a single transaction, and permissioned functions that assume a trusted caller who can in fact be a contract. We also model the economics: can a flash loan make a profitable path out of your invariant assumptions?

We audit Solidity on Ethereum mainnet and all EVM-compatible networks and rollups, including Arbitrum, Optimism, Base, zkSync Era, Polygon, BNB Chain, Avalanche and Linea, and note the chain-specific differences that matter — precompiles, opcode support, sequencer behaviour, reorg assumptions and bridge trust. Foundry is our default framework for proofs of concept; we work in Hardhat projects as well, and we are comfortable with Vyper and Yul where they appear.

DeFi protocols before a mainnet launch or a major upgrade; token and launchpad teams that need a clean report for exchanges and investors; DAOs integrating third-party contracts; and teams that already had an audit but have shipped significant changes since. If the contracts will hold real user funds, a manual Solidity audit is the cheapest insurance you will ever buy.

A small contract set — a token with vesting, a staking contract, a simple vault — takes about a week. A mid-size protocol with two to five thousand lines takes two to three weeks; larger systems are scoped per module. Every quote is fixed, in writing, and includes one retest. We can usually start within one to two weeks of signing.
