Sending ERC-1155 Tokens

Create a transaction on smart account that transfers single ERC-1155 token similar to sending an ERC20 or ERC721 token.
Once you have the Smart Account instance initialized with appropriate config, check code below.
const erc1155Interface = new ethers.utils.Interface([
'function safeTransferFrom(address _from, address _to, uint256 _id, uint256 _value, bytes calldata _data)'
// Encode the transfer of the collectible to recipient
const address = await smartAccount.address;
const data = erc1155Interface.encodeFunctionData(
'safeTransferFrom', [address, recipientAddress, tokenId, amount, '0x']
const tx1 = {
to: nftAddress,
// 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);
