Describe the Problem

User zksync-ethers(v6.12.1) signer to send EIP712 transaction, zksync-ethers depends on ethers.js v6. The transaction can be sent and confirmed on chain. There is an error happens in ethers's abstract-provider (https://github.com/ethers-io/ethers.js/blob/5aba4963e3e8ddfc912747076f5b7fe7a743cfe2/src.ts/providers/abstract-provider.ts#L1088), where it use Trnsaction.from(signedTx) and got error as :
Error: unsupported transaction type (operation="from", code=UNSUPPORTED_OPERATION, version=6.13.2). So the transaction type EIP712 is not supported in transaction.js.

Code Snippet

const transaction = {...tx}
transaction.customData = tx.customData;
                const zksyncSigner = ZksyncSigner.from(
                  // @ts-ignore
                  signer,
                  tx.chainId,
                  new ZksyncProvider(getRpc(tx.chainId))
                );
                const res = await zksyncSigner.sendTransaction({
                  ...transaction,
                  gasLimit: fee.gasLimit,
                  maxPriorityFeePerGas: Number(fee.maxPriorityFeePerGas)
                    ? fee.maxPriorityFeePerGas
                    : 100,
                });
                return res;

Hi @MickWang

I managed to run succefully the EIP712 transaction using ethers 6.13.2 and zksync-ethers: 6.12.1. Here is the code:

import {Provider, types, utils, BrowserProvider, Signer} from 'zksync-ethers';
import {ethers} from 'ethers';

const token = '0x6a4Fb925583F7D4dF82de62d98107468aE846FD1';
const receiver = '0x81E9D85b65E9CC8618D85A1110e4b1DF63fA30d9';
const approvalToken = '0x927488F48ffbc32112F1fF721759649A89721F8F'; // Crown token which can be minted for free
const paymaster = '0x13D0D8550769f59aa241a41897D4859c87f7Dd46'; // Paymaster for Crown token

// Browser wallet should be connected to zkSync Era Sepolia network
const browserProvider = new BrowserProvider((window as any).ethereum);
const provider = Provider.getDefaultProvider(types.Network.Sepolia);
const signer = Signer.from(
     await browserProvider.getSigner(),
     Number((await browserProvider.getNetwork()).chainId),
     provider
);

console.log(`Account1 balance before transfer: ${await signer.getBalance()}`);
console.log(`Account2 balance before transfer: ${await provider.getBalance(receiver)}`);

await signer.sendTransaction({
     from: signer.address,
     to: receiver,
     value: ethers.parseEther('0.01'),
     customData: {
          paymasterParams: utils.getPaymasterParams(paymaster, {
             type: 'ApprovalBased',
             token: approvalToken,
             minimalAllowance: 1,
             innerInput: new Uint8Array(),
           }),
      }
 })
        
console.log(`Account1 balance after transfer: ${await signer.getBalance()}`);
console.log(`Account2 balance after transfer: ${await provider.getBalance(receiver)}`);

Output:

Account1 balance before transfer: 75700023965349567071
Account2 balance before transfer: 192408413800010000
Account1 balance after transfer: 75690023965349567071
Account2 balance after transfer: 202408413800010000
