Use NFTHashi as middleware
You can integrate NFTHashi smart contracts into your contracts.
You can integrate the NFTHashi contract using the following interface and deployed contract addresses.
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
interface IHashi721Bridge {
function xCall(
uint32 destination,
uint256 relayerFee,
uint256 slippage,
address asset,
address to,
uint256 tokenId,
bool isTokenURIIgnored
) external payable returns (bytes32);
}
TBD
Network | Address | Domain ID |
|---|---|---|

contract SampleXApp {

}
function sampleXCall(
uint32 destination, // domain ID from above list
uint256 relayerFee, // check Connext document
uint256 slippage, // check Connext document
address asset, // NFT contract address
address to, // NFT receiver in destination chain
uint256 tokenId, // NFT token ID
uint256 isTokenURIIgnored // if token URI is not required, set true
) public {
// specific logic for your dApp
IHashi721Bridge(nftHashiBridgeContract).xCall(destination, relayerFee, slippage, asset, to, tokenId, isTokenURIIgnored);
}
}
The user must approve the NFTHashi bridge contract to transfer NFT before calling.
