Sei 概述

Sei is a high-performance Layer 1 blockchain with a focus on speed and efficiency to achieve a Web2-like experience. It runs transactions in parallel and uses an efficient consensus design to handle up to 200,000 TPS, with finality under 400 ms. It's fully EVM-compatible and processes transactions at sub-cent costs.

Interacting With Sei APIs

Sei exposes Ethereum-compatible JSON-RPC methods that allow developers to interact with the network programmatically. You can query blockchain state, send transactions, deploy and interact with smart contracts, and subscribe to real-time events via WebSocket.

You can connect by running your own node or by using a hosted provider such as Quicknode, which offers reliable, low-latency access without the need to manage infrastructure.

The Quicknode Sei documentation is continuously updated, but we recommend cross-referencing with the official Sei documentation for the latest API details.

Make Sei API Calls

The quickest way to start building on Sei is to create a Quicknode endpoint and send your first request. Quicknode provides managed Sei endpoints, offering:

• High reliability — globally distributed infrastructure designed to minimize downtime
• Enhanced performance — optimized latency and request handling for production-grade apps

Archive Data Availability

Quicknode's Sei Pacific endpoints provide full archive data access starting from block height 1 (genesis).

For blocks >= 78309999: 使用 x-cosmos-block-height header with REST API requests or specify the height parameter with Tendermint API requests:

Cosmos REST API Example:

curl --location 'https://docs-demo.sei-pacific.quiknode.pro/cosmos/distribution/v1beta1/delegators/sei1xyp8xxely9txewfe7nes2nxrzr0qyrfghrj5cs/rewards' \
--header 'x-cosmos-block-height: 78309999'

Tendermint API Example:

curl --location 'https://docs-demo.sei-pacific.quiknode.pro/block?height=78309999'

For Sei EVM methods: No special headers are required. The earliest block number for EVM methods is 79123881 (Sei V2 upgrade block).
