B3 RPC
B3 概覽
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:
- 高可靠性——全球佈局的基础設施，旨在將停機時間降至最低
- 提升效能——針對生產級應用程式優化延遲與請求處理
- 整合式生態系統——透過 Quicknode Marketplace 上的專用 API（附加元件）以及 Streams 等產品，提供額外功能
請造訪「快速入門」頁面，建立您的端點並發送第一個請求。
