Sei RPC
Descripción general de Sei
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.
