Acta

Acta is an options protocol on Solana that executes through bilaterally signed requests for quote: a buyer signs an intent covering underlying, strike, expiry and premium, a market maker pre-signs a quote, and the two are matched atomically on-chain so neither side can unilaterally withdraw what it has signed. Positions are fully collateralised and held in isolation, expiry settlement is triggered by an independent solver, and the underlying price comes from a Pyth time-weighted average to avoid manipulation of a single print.

It addresses two persistent blockers in on-chain options, namely market makers' reluctance to quote longer tenors and the cross-margin risk that comes from pooled collateral. Requests for quote assign quoting responsibility to a named counterparty, and isolated positions make each position's worst case computable within a bound. The product targets idle native capital such as LSTs and DAO treasuries through structured-yield vaults that carry no liquidation risk. Tooling includes a TypeScript SDK and a Rust maker SDK with WebSocket market data, order signing and instruction assembly. Its category is institutional options infrastructure.
