Module IB20Extensions

Available on crate feature base only.

Expand description

Deliberately partial mirror of base_common_precompiles::IB20, the B-20 token surface.

B-20 tokens are created by the factory at derived addresses, so they cannot be registered per address like the fixed precompiles. These members are therefore available as a Base-only fallback after address-scoped and caller-supplied metadata.

Only Base-specific members belong here. The ERC-20, EIP-2612 and AccessControl portions are omitted on purpose: the global function map is not network-scoped, so adding competing candidates for transfer, balanceOf, approve or permit could change how ordinary token traces decode in any Base-enabled build. Foundry already has to order IStorageCredits against ITIP20 to keep balanceOf’s return type stable, which is the same hazard. b20_surface_excludes_erc20_members pins this boundary.

interface IB20Extensions {
    enum PausableFeature { TRANSFER, MINT, BURN, SEIZE }
    event Memo(address indexed caller, bytes32 indexed memo);
    event BurnedBlocked(address indexed caller, address indexed from, uint256 amount);
    event Seized(address indexed caller, address indexed from, address indexed to, uint256 amount);
    event LastAdminRenounced(address indexed previousAdmin);
    event Paused(address indexed updater, PausableFeature[] features);
    event Unpaused(address indexed updater, PausableFeature[] features);
    event PolicyUpdated(bytes32 indexed policyScope, uint64 oldPolicyId, uint64 newPolicyId);
    function mintWithMemo(address to, uint256 amount, bytes32 memo) external;
    function burnWithMemo(uint256 amount, bytes32 memo) external;
    function burnBlocked(address from, uint256 amount) external;
    function transferWithMemo(address to, uint256 amount, bytes32 memo) external returns (bool);
    function seizeWithMemo(address from, address to, uint256 amount, bytes32 memo) external;
    function pausedFeatures() external view returns (PausableFeature[] memory);
    function isPaused(PausableFeature feature) external view returns (bool);
