Flashblocks RPC
Pending-state aware RPC
Flashblocks-aware RPC for apps that need faster pending-state feedback before a full GIWA block is produced.
Overview
Flashblocks gives applications preconfirmation feedback before waiting for the next complete GIWA block. GIWA documents it as a way to surface transaction state faster for experiences where immediate response matters.
The Flashblocks-aware RPC keeps the normal Ethereum JSON-RPC shape while adding support for pending flashblock state on methods such as eth_call, eth_estimateGas, eth_getBalance, eth_getBlockByNumber, eth_getLogs, eth_getTransactionCount, eth_getTransactionByHash, eth_getTransactionReceipt, and eth_simulateV1.
Good for
- Designed for wallets, payment flows, games, and realtime UX
- Uses pending flashblock state for supported JSON-RPC methods
- Complements the normal public RPC rather than replacing all node infrastructure
Notes
- It is a development/test endpoint with rate limits; production apps should use an appropriate node provider or operate their own Flashblocks-aware node.
