How Do I Add Sei Network to MetaMask?

Steps

1. Open MetaMask.
2. Click the network dropdown menu (top-left, often says "Ethereum Mainnet").
3. Click "Add network" at the bottom.
4. Click "Add a network manually" (if Sei isn't shown in the list).
5. Enter the following details exactly:
   • Network Name: Sei Network
   • New RPC URL: https://evm-rpc.sei-apis.com
   • Chain ID: 1329
   • Currency Symbol: SEI
   • Block Explorer URL (Optional): https://seitrace.com
6. Click "Save".

Explanation & Tips

• Chain ID is Crucial: The most common error is mistyping the Chain ID. It must be 1329 for Sei mainnet.
• "Incorrect Network" Error: If MetaMask shows this after adding, double-check all entered details, especially the Chain ID. You might need to remove the network and add it again carefully. See Fixing "Incorrect Network" Error in MetaMask.
• Alternative Public RPC: If you experience connection issues later, you can try editing the network settings to use an alternative RPC URL like https://sei.drpc.org.

• Testnet: For Sei Testnet (Atlantic-2), use Chain ID 1328 and RPC https://evm-rpc-testnet.sei-apis.com.
