ipAccount

function ipAccount(uint256 chainId, address tokenContract, uint256 tokenId) public view returns (address)

Returns the IPAccount address for the given NFT token.

Parameters:

• chainId: The chain ID where the IP Account is located.
• tokenContract: The address of the token contract associated with the IP Account.
• tokenId: The ID of the token associated with the IP Account.

Returns:

• ipAccountAddress: The address of the IP Account associated with the given NFT token.

​

getIPAccountImpl

function getIPAccountImpl() external view override returns (address)

Returns the IPAccount implementation address.

Returns:

• address: The address of the IPAccount implementation.

​

_registerIpAccount (internal)

function _registerIpAccount(
    uint256 chainId,
    address tokenContract,
    uint256 tokenId
) internal returns (address ipAccountAddress)

Deploys an IPAccount contract with the IPAccount implementation and returns the address of the new IP. The IPAccount deployment delegates to public ERC6551 Registry.

Parameters:

• chainId: The chain ID where the IP Account will be created.
• tokenContract: The address of the token contract to be associated with the IP Account.
• tokenId: The ID of the token to be associated with the IP Account.

Returns:

• ipAccountAddress: The address of the newly created IP Account.

​

_get6551AccountAddress (internal)

function _get6551AccountAddress(
    uint256 chainId,
    address tokenContract,
    uint256 tokenId
) internal view returns (address)

Helper function to get the IPAccount address from the ERC6551 registry.

Parameters:

• chainId: The chain ID where the IP Account is located.
• tokenContract: The address of the token contract associated with the IP Account.
• tokenId: The ID of the token associated with the IP Account.

Returns:

• address: The address of the IP Account.

​

_upgradeIPAccountImpl (internal)

function _upgradeIPAccountImpl(address newIpAccountImpl) internal

Helper function to upgrade the IPAccount implementation.

Parameters:

• newIpAccountImpl: The address of the new IPAccount implementation.
