B3 RPC

With Quicknode, you get access to our global B3 network which always routes your API requests to the nearest available location, ensuring low latency and the fastest speeds.

B3の概要

B3 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 posting compressed transaction data to Ethereum for settlement security. B3 maintains bytecode-level EVM equivalence, ensuring full compatibility with existing Ethereum applications. Transactions are ordered by sequencers for low-latency block production, while Ethereum ensures security through a fraud-proof challenge period.

B3 is designed for high-performance blockchain infrastructure, delivering fast transaction throughput and low fees. This makes it well-suited for decentralized applications that demand efficient and cost-effective execution.

Interacting with B3's APIs

B3 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 B3's architectural differences, some RPC methods may behave differently from those on Ethereum. The Quicknode B3 documentation is continuously evolving as the chain undergoes upgrades and changes, so we highly recommend cross-referencing with the official B3 documentation for the latest updates and RPC differences.

Make B3 API Calls

The quickest way to start building on B3 is to create a Quicknode endpoint and send your first JSON-RPC request.

Quicknode provides managed B3 endpoints, giving you immediate access to the B3 Mainnet without the overhead of running infrastructure. These endpoints offer:

  • 高い信頼性– ダウンタイムを最小限に抑えるよう設計された、世界中に分散したインフラストラクチャ
  • パフォーマンスの向上– 実運用レベルのアプリ向けに、レイテンシとリクエスト処理を最適化
  • 統合エコシステム– Quicknode Marketplace上の専用API(アドオン)やStreamsなどの製品を通じて、追加機能を提供
