# Welcome to Primev

> We build [mev-commit](/v1.2.x/concepts/mev-commit-intro/what-is-mev-commit), the preconfirmation protocol that makes Ethereum fast. mev-commit gives transactions near-instant finality by letting block builders commit to including them before a block is produced.

On top of mev-commit we've built **Fast Protocol**: a suite of products that put preconfirmations to work for users, developers, and AI agents:

### mev-commit Network Roles

mev-commit is powered by a network of bidders, providers, and validators. If you operate infrastructure on Ethereum and want to participate, visit the [quickstart guide](/v1.2.x/get-started/quickstart) or explore the resources below for your role:

### Featured: Fast Swaps

Swap tokens on Ethereum mainnet and earn mev rewards. Fast Swaps routes your trades through a competitive solver auction backed by mev-commit preconfirmations — your swap feels instant, and you keep at least 90% of the mev your transactions generate.
