IBatchMint

Hashgraph Asset Tokenization

IBatchMint

Interface for batch minting tokens to multiple addresses in a single transaction.

Exposes the batchMint operation used by the BatchMintFacet Diamond facet. Callers must hold the issuer or agent role; each recipient must pass identity and compliance checks, and the cumulative issuance must not exceed the configured maximum supply cap.

Methods

batchMint

function batchMint(address[] _toList, uint256[] _amounts) external nonpayable

Batch mint tokens to multiple addresses.

Iterates over _toList and _amounts in two passes: first validates identity, compliance, and cap constraints for every recipient, then issues tokens to each address via ERC1594StorageWrapper.issue. Reverts if the token is paused, if the arrays differ in length, if the caller lacks the issuer or agent role, if a recipient fails identity or compliance checks, or if any single mint would exceed the maximum supply. Restricted to non-multi-partition tokens.

Parameters

Name	Type	Description
_toList	address[]	Ordered list of recipient addresses.
_amounts	uint256[]	Ordered list of token amounts corresponding to each recipient.

initializeBatchMint

function initializeBatchMint() external nonpayable

Initialises the batch mint capability on the token.

Callable once; subsequent calls revert with FacetAlreadyRegistered. Requires DEFAULT_ADMIN_ROLE. Called by the factory during deployment.

Events

BatchMintInitialized

event BatchMintInitialized()

Emitted once when the batch mint capability is initialised on a token.

Fires exclusively from initializeBatchMint after the storage write succeeds.
