Sending ERC-721 (NFT) Tokens
Create a transaction on a smart account that transfers a single ERC-721 token similar to sending an ERC20 token.
Once you have the Smart Account instance initialized with the appropriate config, check the code below.
const erc721Interface = new ethers.utils.Interface([
'function safeTransferFrom(address _from, address _to, uint256 _tokenId)'
])
// Encode an ERC-721 token transfer to recipient of the specified amount
const address = await smartAccount.address;
const data = erc721Interface.encodeFunctionData(
'safeTransferFrom', [address, recipientAddress, tokenId]
)
const tx = {
to: nftAddress,
data
}
// Transaction events subscription
smartAccount.on('txHashGenerated', (response) => {
console.log('txHashGenerated event received via emitter', response);
});
smartAccount.on('txMined', (response) => {
console.log('txMined event received via emitter', response);
});
smartAccount.on('error', (response) => {
console.log('error event received via emitter', JSON.stringify(response));
});
// Sending transaction
const txResponse = await smartAccount.sendTransaction({ transaction: tx });
console.log('UserOp Hash', txResponse);
const txReciept = await txResponse.wait();
console.log('Tx hash', txReciept.transactionHash);
