Primev

Primev builds mev-commit, a preconfirmation protocol that makes Ethereum fast by giving transactions near-instant finality through builder commitments. On top of mev-commit, it offers the Fast Protocol suite—Fast Swaps, FAST RPC, and Fastx402—to deliver preconfirmed execution and MEV rewards to users, developers, and AI agents.

Description

Primev develops mev-commit, a preconfirmation protocol and P2P coordination network for the MEV ecosystem that enables bidders and providers (e.g., searchers/solvers/market makers and block builders/relays/rollup sequencers) to exchange execution bids and cryptographic commitments, supporting “fast games” like preconfirmations and near-instant transaction finality on Ethereum. Building on mev-commit, Primev offers the Fast Protocol suite including Fast Swaps (token swaps with preconfirmed execution and MEV rewards), FAST RPC (a drop-in Ethereum RPC enabling preconfirmations for wallets and dapps), and Fastx402 (x402-based payments with sub-second USDC settlement). The project is open-source, includes developer resources such as API references and tooling, and supports participation from validators (including via staking or restaking such as EigenLayer operators).
