Interface of the ERC20 standard as defined in the EIP.
function interchainTransfer(string destinationChain, bytes recipient, uint256 amount, bytes metadata) external payable
Implementation of the interchainTransfer method.
We chose to either pass metadata as raw data on a remote contract call, or if no data is passed, just do a transfer.
A different implementation could use metadata to specify a function to invoke, or for other purposes as well.
| Name | Type | Description |
|---|---|---|
| destinationChain | string | The destination chain identifier. |
| recipient | bytes | The bytes representation of the address of the recipient. |
| amount | uint256 | The amount of token to be transferred. |
| metadata | bytes | Optional metadata for the call for additional effects (such as calling a destination contract). |
function interchainTransferFrom(address sender, string destinationChain, bytes recipient, uint256 amount, bytes metadata) external payable
Implementation of the interchainTransferFrom method
We chose to either pass metadata as raw data on a remote contract call, or, if no data is passed, just do a transfer.
A different implementation could use metadata to specify a function to invoke, or for other purposes as well.
| Name | Type | Description |
|---|---|---|
| sender | address | The sender of the tokens. They need to have approved msg.sender before this is called. |
| destinationChain | string | The string representation of the destination chain. |
| recipient | bytes | The bytes representation of the address of the recipient. |
| amount | uint256 | The amount of token to be transferred. |
| metadata | bytes | Optional metadata for the call for additional effects (such as calling a destination contract.) |
