Sending ERC-721 (NFT) Tokens

Sending an ERC-721 NFT is similar to sending an ERC-20 token. The only notable difference is in the contract standard itself:

const erc721Interface = new ethers.utils.Interface([
  'function safeTransferFrom(address _from, address _to, uint256 _tokenId)'
])
 
// Encode the transfer of the NFT tokenId to recipient
const address = await wallet.getAddress()
const data = erc721Interface.encodeFunctionData(
  'safeTransferFrom', [address, recipientAddress, tokenId]
)
 
const transaction = {
  to: erc721TokenAddress,
  data
}
 
const signer = wallet.getSigner()
const txnResponse = await signer.sendTransaction(transaction)
console.log(txnResponse)

With batching functionality, you can send multiple token transfers in a single native transaction:

const erc721Interface = new ethers.utils.Interface([
  'function safeTransferFrom(address _from, address _to, uint256 _tokenId)'
])
 
// Encode two different ERC-721 token transfers
const data1 = erc721Interface.encodeFunctionData(
  'safeTransferFrom', [address, recipient1Address, amount1]
)
const data2 = erc721Interface.encodeFunctionData(
  'safeTransferFrom', [address, recipient2Address, amount2]
)
 
const transaction1 = {
  to: erc721ContractAddress,
  data: data1
}
 
const transaction2 = {
  to: erc721ContractAddress,
  data: data2
}
 
// Send a multiple transactions as a single bundle which is executed as one transaction on chain.
const signer = wallet.getSigner()
const txnResponse = await signer.sendTransactionBatch([transaction1, transaction2])
console.log(txnResponse)
