Description

Secstant is an in-development Sigma Prime product for AI-assisted security reviews. It is designed to help reviewers preserve context across large codebases, organize noisy static-analysis output, cross-reference historical findings, and work efficiently without losing the threat model. It reflects Sigma Prime’s work across smart contracts, protocols, infrastructure, and frontend applications; detailed capabilities, pricing, and release timing have not been published, and an early-access waitlist is open.

Anchor


Project Links


Description

Anchor is a production, open-source Rust implementation of the SSV protocol, the open standard for Distributed Validator Technology (DVT) on Ethereum. It uses the protocol’s threshold-cryptography model, in which a validator key is split across multiple operators so no one operator can sign alone. As an independent implementation alongside the existing Go client, Anchor adds client diversity and improves resilience for SSV/DVT deployments.
