What we ship

Pick the engagement that fits where you are.

Subscription

Full-Stack Audit

A smart contract audit and an off-chain pentest run in parallel by the same firm. The boundary between on-chain and off-chain gets reviewed jointly.

Pentest

Application security

Black-box and white-box pentesting for dApps, wallets, APIs, and Web3 backends. Auth, session, key management, and integration risk with the on-chain side.

AI

AI and MCP audits

Prompt injection testing, AI red teaming, and security reviews for MCP servers and AI-powered Web3 applications.

Build

Smart contract development

Secure-by-design smart contract development for Ethereum, Solana, and other ecosystems. Build, review, and deploy with the audit team alongside.
