Class: AccountInterface
Interface for interacting with Starknet account contracts
Extends ProviderInterface to provide account-specific functionality including:
- Transaction execution and signing
- Fee estimation for various transaction types
- Contract deployment through UDC (Universal Deployer Contract)
- Paymaster support for sponsored transactions
- EIP-712 message signing
Remarks
Implementations of this interface typically handle the complexities of:
- Nonce management
- Transaction signing with the account's private key
- Interaction with the account contract's execute entrypoint
