FAQ
Frequently asked questions
What is the Sei EVM chain ID?
Sei EVM mainnet chain ID is 1329 (hex 0x531). The Cosmos side uses string chain id pacific-1, which is not interchangeable with the EVM numeric id.
What is the official Sei EVM RPC URL?
The Sei Foundation RPC URL is https://evm-rpc.sei-apis.com. dRPC (https://sei.drpc.org) is a public alternative for redundancy.
How do I add Sei EVM to MetaMask?
Open MetaMask, click the network dropdown, click Add Network, then Add a network manually. Paste Network name Sei, RPC URL https://evm-rpc.sei-apis.com, chain ID 1329, currency symbol SEI, and block explorer https://seitrace.com. Save and switch.
Why does Sei have two different chain identifiers?
Sei runs both a Cosmos SDK side and an EVM side on the same validator set. Chain ID 1329 refers specifically to the EVM execution layer that MetaMask and Solidity tooling use; Cosmos-native clients (like Keplr) instead use the string chain id pacific-1. Don't mix the two up when configuring a wallet or RPC client.
What are the best paid RPC providers for Sei EVM?
QuickNode and dRPC both list Sei EVM support alongside their Ethereum and L2 coverage. See the full comparison at /chains/rpc-providers for free tiers and feature breakdowns.
