Sei RPC
Sei 개요
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

지원되는 네트워크
Quicknode provides access to the following Sei networks:
Quicknode의 Sei Pacific endpoints provide full archive data access starting from block height 1 (genesis).
For blocks >= 78309999:
Use the 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).
