IERC7821

Interface for minimal batch executor.

Functions

execute

*Executes the calls in executionData. Reverts and bubbles up error if any call fails. executionData encoding:

• If opData is empty, executionData is simply abi.encode(calls).
• Else, executionData is abi.encode(calls, opData). See: https://eips.ethereum.org/EIPS/eip-7579 Supported modes:
• bytes32(0x01000000000000000000...): does not support optional opData.
• bytes32(0x01000000000078210001...): supports optional opData. Authorization checks:
• If opData is empty, the implementation SHOULD require that msg.sender == address(this).
• If opData is not empty, the implementation SHOULD use the signature encoded in opData to determine if the caller can perform the execution. opData may be used to store additional data for authentication, paymaster data, gas limits, etc. For calldata compression efficiency, if a Call.to is address(0), it will be replaced with address(this).*

supportsExecutionMode

*This function is provided for frontends to detect support. Only returns true for:

• bytes32(0x01000000000000000000...): does not support optional opData.
• bytes32(0x01000000000078210001...): supports optional opData.*

function supportsExecutionMode(bytes32 mode) external view returns (bool);
