How to Add Sei to MetaMask

Summary: Due to architectural differences, MetaMask cannot support the Sei Network, which is built on the Cosmos-SDK and not the EVM framework.

To engage with Sei’s ecosystem, including its DeFi applications, users must opt for Sei-compatible wallets like Fin Wallet. This ensures seamless interaction with Sei's fast, scalable blockchain, designed specifically for digital asset exchanges and trading applications.

Can I Add Sei to MetaMask?

Unfortunately, you cannot add Sei to MetaMask. This limitation arises because Sei is built on the Cosmos-SDK, which uses a different blockchain architecture than the Ethereum Virtual Machine (EVM) framework MetaMask is designed to support. The distinct nature of Sei's infrastructure, rooted in the Cosmos ecosystem, means MetaMask cannot interface with Sei or manage its assets directly. To access Sei's features, including its native DeFi applications and low fees, users are advised to use wallets and interfaces specifically designed for Sei's ecosystem

How to Install a Sei MetaMask Alternative

Due to the unique architecture of the Sei Network, it does not support MetaMask's Ethereum Virtual Machine (EVM) compatibility. To manage Sei's native tokens and interact with applications on the Sei Network SDK, an alternative wallet is essential. Fin Wallet is a recommended choice, known for its specific compatibility with the Sei ecosystem. Here's a straightforward guide to setting up a Sei-compatible wallet:

1. Visit Fin Wallet: Navigate to the Fin Wallet application and download the extension for your browser.
2. Select Installation Platform: Choose the appropriate platform for your wallet installation. Options include Chrome, Firefox, iOS, or Android.
3. Complete Setup: Follow the setup instructions carefully, especially regarding the secure storage of your seed phrase. It's crucial to keep this in a safe, offline place.
4. Connect to Sei Network: Within the wallet, find and select the Sei Network to connect your wallet to it.

Sei RPC and Network Details

To directly access Sei Network through an alternative wallet, it's crucial to use the correct RPC endpoints. Sei's network is divided into the testnet (Atlantic-2) and the mainnet (Pacific-1), each with specific connection details. Users can refer to Sei's official documentation for the most current and accurate information on these networks.
