Sec3

Sec3 (formerly Soteria) is a Solana-native security firm, founded in 2021, providing smart-contract security audits, formal verification, and post-deployment on-chain monitoring for high-stakes protocols and institutions building on Solana. The team combines manual security review by experienced researchers with automated tooling and formal methods, and maintains open-source tools including the X-Ray static analysis scanner and IDL Guesser. Sec3 has secured protocols such as the Solana Foundation, Wormhole, Kamino Finance, Helium Network, Jupiter, Orca, Metaplex, and Solana Mobile, publishes an annual Solana Security Ecosystem Report, and offers free nonce and multisig monitoring tooling. Surfaced as a portfolio company of Multicoin Capital and enriched from Sec3's public surface; it is a security-services firm with no self-serve public API.
