Beosin

Beosin is a blockchain security firm focused on audits, compliance tooling, and incident response.

Its public product lineup includes smart contract security audits, Beosin KYT for transaction monitoring and AML analysis, and tracing services for stolen or suspicious fund flows.

Beosin also states that its KYT platform supports full node transaction data for chains including TON, which makes it relevant for teams and compliance operators working in the TON ecosystem.

The company therefore fits this registry as both a contract security provider and a transaction intelligence vendor.
