Blast RPC

With Quicknode, you get access to our global Blast network which always routes your API requests to the nearest available location, ensuring low latency and the fastest speeds.

Blast Overview

Blast is a Layer 2 scaling solution for Ethereum, built on the OP Stack—the same technology that powers Optimism. It uses optimistic rollups to execute transactions off-chain while submitting compressed transaction data to Ethereum for security and settlement. Blast maintains bytecode-level EVM equivalence, ensuring full compatibility with existing Ethereum applications. The network employs sequencers to order transactions and achieve low-latency block production, while Ethereum provides finality through a fraud-proof challenge period.

Blast's defining feature is its native yield: ETH deposits are staked through protocols like Lido or Rocket Pool to generate staking rewards automatically, and USDB Blast's native stablecoin earns yield from real world, yield-bearing assets.

Interacting with Blast's APIs

Blast nodes expose a JSON-RPC interface that is compatible with Ethereum's JSON-RPC API. This means developers can use Ethereum's native tools, such as Foundry, Hardhat, and popular Web3 libraries, without modification.

However, due to Blast's architectural differences, some RPC methods may behave differently from those on Ethereum. The Quicknode Blast documentation is continuously evolving as the chain undergoes upgrades and changes, so we highly recommend cross-referencing with the official Blast documentation for the latest updates and RPC differences.

Make Blast API Calls

The quickest way to start building on Blast is to create a Quicknode endpoint and send your first JSON-RPC request.

Quicknode provides managed Blast endpoints, giving you immediate access to the Blast Mainnet and Sepolia Testnet without the overhead of running infrastructure. These endpoints offer:

  • Haute fiabilité – une infrastructure distribuée mondialement conçue pour minimiser les temps d'arrêt
  • Performances améliorées – latence et gestion des requêtes optimisées pour les applications de qualité production
  • Écosystème intégré – fonctionnalités supplémentaires via des API spécialisées (add-ons) sur le Quicknode Marketplace et des produits comme Streams
