Ethereum transactions can now be preconfirmed in only a fraction of a second with new tech from an Ethereum infrastructure platform.
Primev says its FAST RPC (Distant Process Name) permits transactions to be preconfirmed and set for inclusion in blocks in underneath 200ms — enabling every little thing from Ether (ETH) transfers and interacting with sensible contracts to minting non-fungible tokens (NFTs) at “blazing pace.”
Preconfirmation is an early sign from a block builder indicating a transaction will doubtless be included within the subsequent block, whereas block inclusion refers to a transaction being added right into a block.
RPCs like FAST RPC join crypto wallets to blockchain nodes, enabling customers to ship transactions and work together with decentralized purposes onchain.
From the person’s perspective 200ms might theoretically rival high-speed layer 1 blockchains like Sui, the place transactions are normally confirmed inside 200ms.
Primev’s founder, Murat Akdeniz, posted a reside demonstration to X on Monday, displaying a near-instant ETH switch by way of Ethereum self-custody pockets MetaMask, which he said was preconfirmed in 377ms and included in the identical block.
Akdeniz stated his staff has been working for greater than two years to “supercharge Ethereum” to those speeds.
Ethereum L1 is painfully gradual 😩
Can devs PLEASE repair this?!?
For two+ years, the @primev staff has been grinding to supercharge Ethereum mainnet.
Immediately: MILLISECOND preconfirmations… ON L1! 🚀watch me ship ETH blazing quick on this 18s vid pic.twitter.com/Diao4VfHzT

FAST RPC hasn’t been examined at scale
Essentially the most broadly used RPCs on Ethereum are Infura and Alchemy’s answer, which, whereas slower than Primev’s FAST RPC, have a a lot bigger node distribution and have been battle-tested underneath a lot heavier community hundreds.
Greater than 400,000 builders leverage the Consensys-built Infura to attach with Ethereum, whereas Alchemy facilitates greater than $150 billion in transactions yearly from over 100 customers worldwide.
Nonetheless, Primev’s answer might provide a lot quicker transactions for customers preferring to remain on Ethereum mainnet moderately than switching to Ethereum layer-2 solutions.

FastRPC is comparatively straightforward to arrange
Primev’s answer can simply be built-in by connecting to a crypto wallet like MetaMask or WalletConnect and changing Infura and Alchemy’s RPC with FAST RPC.
Customers should then deposit funds into Primev’s “fuel tank” at pockets deal with “0x24A…c2ACf” earlier than they’ll freely work together onchain.
