FAQ

EVM audit FAQ

Which languages do you cover?

Solidity, Vyper, Solana Rust, CosmWasm, Go, Aptos Move, Sui Move, JavaScript, Circom, Halo 2 and more, plus Web2 frontends and backends in JavaScript, Rust and Python.

Is it only manual review?

No. Different systems call for different techniques. Pentesting, formal verification and fuzzing are core disciplines, and we pick the mix that fits yours.

Can we read past audits?

Yes. Every public security review from the OtterSec team is listed at osec.io/audits.

Do you work beyond the major chains?

Yes. We love niche languages and have worked with teams on Optimism, Arbitrum, Polygon, Algorand, Stellar, Sei, StarkNet and more.
