Our Story
SOKEN LTD is registered in England (Companies House 15253906) and owned by Constantine Manko. We build and secure software end to end: smart contract audits on EVM, Solana, Move, Cairo and TON, penetration tests and code-level security reviews, backends in Python, TypeScript and Go, frontends in React and Next.js, bots, and retrieval features answering from a client's own data. For token projects we add legal opinions and compliance documents. Our audit reports are public on GitHub.
What Sets Us Apart
Public audit history
Every audit report we deliver is published in a Git repository with full revision history, so a buyer can read the actual work before hiring us: github.com/Soken-LTD/smart-contract-auditsWe build what we review
The same engineers who write backends and on-chain programs read the contracts for reentrancy and oracle assumptions, so findings arrive with a fix a developer can apply.One contract for build, security and legal
Development, the security review and the legal opinion for a token launch run through one company, so nothing waits on a third vendor.
