Beosin

Beosin is a Singapore-headquartered blockchain security firm that combines manual smart contract auditing with formal verification technology, AI-driven on-chain monitoring, and crypto tracing to protect projects across more than 30 public chains including Solana.

Founded in March 2018 by researchers and professors from leading universities, Beosin has grown to more than 180 security experts including 40-plus PhDs. Headquartered in Singapore with offices in South Korea, Japan, and more than 10 other countries, the company holds SOC 2 and ISO 27001 certifications and publishes threat intelligence through the Blockchain Security Alliance, including the 2025 H1 Global Web3 Security Report with Footprint Analytics. Partnerships include HashKey Group for AML and compliance, Singapore University of Social Sciences NiFT, and the Singapore Blockchain Innovation Programme.

Beosin's security approach spans the full project lifecycle through four integrated products. Its smart contract audit service covers Ethereum, BNB Chain, Polygon, Solana, Polkadot, NEAR, Cosmos, zkSync, Arbitrum, Aptos, Sui, and more. Beosin VaaS, a self-service scanner with a free tier, achieves over 97 percent detection accuracy across 100-plus vulnerability classes using formal verification and supports EVM and WASM contracts. Beosin EagleEye monitors transaction behavior around the clock and can trigger automated blocking for audited projects. Beosin TRACE generates AI-produced transaction maps across Solana, TON, Aptos, Sui, and Ethereum to trace stolen funds through mixers, bridges, and exchanges. TRACE is used by law enforcement and legal teams for asset recovery proceedings. The KYT/AML suite labels wallet addresses for risk scoring and now natively supports Solana.

Across the Solana and SVM ecosystem, Beosin has audited Sonic SVM (HyperFuse Guardian Nodes in September 2024, veSONIC in December 2024), SOON Network's InterSOON Bridge core contracts, and protocols including RateX, SEGA, and Pumpup. In total Beosin has audited more than 2,400 smart contracts, identified over 45,000 vulnerabilities, and labeled over 2 billion wallet addresses. Beosin KYT operates natively on Solana and the firm publishes Solana-specific security research covering cross-chain protocol audit checkpoints for bridge contracts.
