IPAccountImpl.sol

The Story Protocol's implementation of the IPAccount.

State Variables

ACCESS_CONTROLLER

address public immutable ACCESS_CONTROLLER;

Functions

receive

receive() external payable override(Receiver, IIPAccount);

constructor

Creates a new IPAccountImpl contract instance

Initializes the IPAccountImpl with an AccessController address which is stored
in the implementation code's storage.
This means that each cloned IPAccount will inherently use the same AccessController
without the need for individual configuration.

constructor(address accessController, address ipAssetRegistry, address licenseRegistry, address moduleRegistry)
    IPAccountStorage(ipAssetRegistry, licenseRegistry, moduleRegistry);

Parameters

Name	Type	Description
`accessController`	`address`	The address of the AccessController contract to be used for permission checks
`ipAssetRegistry`	`address`
`licenseRegistry`	`address`
`moduleRegistry`	`address`

supportsInterface

Checks if the contract supports a specific interface

function supportsInterface(bytes4 interfaceId)
    public
    view
    override(ERC6551, IPAccountStorage, IERC165)
    returns (bool);

Parameters

Name	Type	Description
`interfaceId`	`bytes4`	The interface identifier, as specified in ERC-165

Returns

Name	Type	Description
`<none>`	`bool`	bool is true if the contract supports the interface, false otherwise

token

Returns the identifier of the non-fungible token which owns the account

function token() public view override(ERC6551, IIPAccount) returns (uint256, address, uint256);

Returns

Name	Type	Description
`<none>`	`uint256`	chainId The EIP-155 ID of the chain the token exists on
`<none>`	`address`	tokenContract The contract address of the token
`<none>`	`uint256`	tokenId The ID of the token

isValidSigner

Checks if the signer is valid for executing specific actions on behalf of the IP Account.

function isValidSigner(address signer, bytes calldata data)
    public
    view
    override(ERC6551, IIPAccount)
    returns (bytes4 result);

Parameters

Name	Type	Description
`signer`	`address`	The signer to check
`data`	`bytes`	The data to be checked. The data should be encoded as `abi.encode(address to, bytes calldata)`, where `address to` is the recipient and `bytes calldata` is the calldata passed to the recipient. If `data.length == 0`, it is also considered valid, implying that the signer is valid for all actions.

Returns

Name	Type	Description
`result`	`bytes4`	The function selector if the signer is valid, 0 otherwise

owner

Returns the owner of the IP Account.

function owner() public view override(ERC6551, IIPAccount) returns (address);

Returns

Name	Type	Description
`<none>`	`address`	The address of the owner.

state

Returns the IPAccount's internal nonce for transaction ordering.

function state() public view override(ERC6551, IIPAccount) returns (bytes32 result);

isValidSigner

Checks if the signer is valid for the given data and recipient via the AccessController permission system.

function isValidSigner(address signer, address to, bytes calldata data) public view returns (bool);

Parameters

Name	Type	Description
`signer`	`address`	The signer to check
`to`	`address`	The recipient of the transaction
`data`	`bytes`	The calldata to check against

Returns

Name	Type	Description
`<none>`	`bool`	bool is true if the signer is valid, false otherwise

executeWithSig

function executeWithSig(
    address to,
    uint256 value,
    bytes calldata data,
    address signer,
    uint256 deadline,

`signer`	`address`	The signer of the transaction.
`deadline`	`uint256`	The deadline of the transaction signature.
`signature`	`bytes`	The signature of the transaction, EIP-712 encoded.

execute

Executes a transaction from the IP Account.

function execute(address to, uint256 value, bytes calldata data) external payable returns (bytes memory result);

Parameters

`value`	`uint256`	The amount of Ether to send.
`data`	`bytes`	The data to send along with the transaction.

Returns

Name	Type	Description
`result`	`bytes`	The return data from the transaction.

execute

Override 6551 execute function.
Only "CALL" operation is supported.

function execute(address to, uint256 value, bytes calldata data, uint8 operation)
    public
    payable
    override
    returns (bytes memory result);

Parameters

`value`	`uint256`	The amount of Ether to send.
`data`	`bytes`	The data to send along with the transaction.
`operation`	`uint8`	The operation type to perform, only 0 - CALL is supported.

Returns

Name	Type	Description
`result`	`bytes`	The return data from the transaction.

executeBatch

Executes a batch of transactions from the IP Account.

function executeBatch(Call[] calldata calls, uint8 operation)
    public
    payable
    override
    returns (bytes[] memory results);

Parameters
