How to Add SEI Network to MetaMask

Understanding MetaMask and SEI Network

MetaMask is primarily an Ethereum Virtual Machine (EVM) compatible wallet. The native SEI network is not EVM-compatible, which means you cannot directly add SEI Network to MetaMask as a custom RPC network in the same way you would add Polygon or Avalanche.

The Solution: Wrapped SEI (ERC-20)

To manage SEI tokens within MetaMask, you need to use a 'wrapped' version of SEI that exists on an EVM-compatible chain, like Ethereum. This is typically an ERC-20 token that represents SEI on a 1:1 basis. The process involves adding this specific ERC-20 token to your wallet.

Step-by-Step Guide to Add Wrapped SEI

1. Ensure You're on Ethereum Mainnet: Open MetaMask and make sure your selected network is "Ethereum Mainnet".
2. Import Token: Click on the "Import tokens" link at the bottom of your asset list.
3. Enter Contract Address: Switch to the "Custom Token" tab and paste the official contract address for wrapped SEI. Always verify this address on a trusted source like Etherscan or the official SEI project documentation.
4. Add and Confirm: The token symbol (e.g., WSEI) and decimals should auto-fill. Click "Add Custom Token," then "Import Tokens" to confirm.

By following these steps, you can successfully view and manage your wrapped SEI tokens in MetaMask. Remember, you are interacting with an ERC-20 version of the token, not the native SEI coin itself, which is a crucial distinction even though you can't directly add SEI Network to MetaMask.
