OmnichainERC20Transfers

Abstract contract that provides the transfer operations of the Omnichain ERC20 Data Manager

transfer

function transfer(OmnichainAddress to, uint256 amount) public payable virtual returns (bool)

Transfers amount tokens from the caller's account to to

If the chain ID of to is the same as the current chain ID, the transfer is done on the single chain otherwise, the transfer is done via Omnichain Caller may receive native coin refund, so if it's a contract it MUST have receive() or payable fallback()

Parameters

Return Values

transfer

function transfer(OmnichainAddress to, uint256 amount, address payable refundAddress) public payable virtual returns (bool)

Transfers amount tokens from the caller's account to to

If the chain ID of to is the same as the current chain ID, the transfer is done on the single chain otherwise, the transfer is done via Omnichain

Parameters

Return Values

transfer

function transfer(address to, uint256 amount) public virtual returns (bool)

Transfers amount tokens from the caller's account to to

The transfer is done on the local chain

Parameters

Return Values

transferFrom

function transferFrom(address from, address to, uint256 amount) public virtual returns (bool)

Transfers amount tokens from from to to

The caller must have allowance for from's tokens of at least amount The transfer is done on the local chain
