The Kernel Account API powers and controls the smart contract wallets called, Kernel Accounts.
Kernel Accounts are a simple smart contract wallet with the same address on all EVM chains and connected to a user's email, social account, phone, or an app provider. The Kernel Account API can be used to submit a transaction or sign a message through a target wallet.
Submit a Transaction
To send a transaction through a Kernel Account, see the Kernel Tx endpoint in Postman.
