Use NFTHashi as middleware

You can integrate NFTHashi smart contracts into your contracts.

Overview

You can integrate the NFTHashi contract using the following interface and deployed contract addresses.

Interface

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
interface IHashi721Bridge {
function xCall(
uint32 destination,
uint256 relayerFee,
address asset,
address to,
uint256 tokenId,
bool isTokenURIIgnored
) external payable returns (bytes32);
}

Smart Contract Example

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
interface IHashi721Bridge {
function xCall(
uint32 destination,
uint256 relayerFee,
address asset,
address to,
uint256 tokenId,
bool isTokenURIIgnored
) external payable returns (bytes32);
}
contract SampleXApp {
address nftHashiBridgeContract;
constructor(address _nftHashiBridgeContract) {
nftHashiBridgeContract = _nftHashiBridgeContract;
}
function sampleXCall(
uint32 destination, // domain ID from above list
uint256 relayerFee, // check Connext document
address asset, // NFT contract address
address to, // NFT receiver in destination chain
uint256 tokenId, // NFT token ID
bool isTokenURIIgnored // if token URI is not required, set true
) public {
// specific logic for your dApp
IHashi721Bridge(nftHashiBridgeContract).xCall(destination, relayerFee, asset, to, tokenId, isTokenURIIgnored);
}
}

Interact from frontend

The user must approve the NFTHashi bridge contract to transfer NFT before calling.
