What is Fast Protocol?

Fast Protocol is a preconfirmations on Ethereum Mainnet through its FAST RPC infrastructure, developed by Primev—a MEV research and cryptography-focused lab — to deliver ultra-low-latency transaction commitments that ensure safe, certain execution for dApps and wallets without MEV exploitation or censorship risks.

The protocol leverages private mempools, bundle support, atomicity guarantees, and global endpoints with 100% uptime to mitigate front-running and enhance user experience, positioning Ethereum as a faster, more private network via tools like the mev-commit system for real-time priority ordering and programmable privacy.
