Primev’s FAST RPC Delivers Sub-200ms Ethereum Transaction Preconfirmations

Published: 2025-10-23 20:02:30 |

Primev’s FAST RPC is a new Ethereum RPC endpoint that delivers sub-200ms transaction preconfirmations, enabling near-instant feedback for ETH transfers, smart contract calls and NFT mints. Traders integrate FAST RPC via MetaMask by switching their RPC endpoint and funding Primev’s gas tank. In live tests, ETH transfers were preconfirmed in 377 ms and included in the same block. Developed over two years without altering Ethereum’s core protocol, FAST RPC enhances perceived Layer 1 speed and rivals specialized blockchains like Sui. If performance holds under heavy load, it could process billions in annual transactions and spur DeFi and NFT activity on Ethereum.

Bullish

FAST RPC’s sub-200ms preconfirmation reduces latency and enhances user experience on Ethereum Layer 1, lowering friction for high-frequency traders and developers. By delivering near-instant transaction feedback without protocol changes, it may drive higher on-chain activity in DeFi and NFT markets. If the service sustains performance under heavy load, increased adoption could lead to greater demand for ETH and bolster network value, generating bullish momentum both short term—as traders capitalize on faster execution—and long term through infrastructure-led growth.
