ℹ Introduction To Sei Wallets

Wallets are essential for managing assets and interacting with the Sei blockchain, with different options offering various features and security levels.

Manually importing a wallet using a mnemonic from an EVM-only app to a Cosmos-based app, or vice versa, is not recommended. Different Coin Types can cause mismatched wallet addresses and lead to unexpected issues.
