zkSync を試した

Rollup が熱いらしい。

チュートリアルをやる

L2 にデポジットする

async function main(): Promise<void> {
  const MNEMONIC = process.env.MNEMONIC!;
  const syncProvider = await zksync.getDefaultProvider("rinkeby");
  const ethersProvider = ethers.getDefaultProvider("rinkeby");

  // memo: 0x13FCd5b4348feFe49aAcf98275cBd9f5F2A2acd2
  const ethWallet =
    ethers.Wallet.fromMnemonic(MNEMONIC).connect(ethersProvider);

  console.log(ethWallet.address);

  const syncWallet = await zksync.Wallet.fromEthSigner(ethWallet, syncProvider);

  const deposit = await syncWallet.depositToSyncFromEthereum({
    depositTo: syncWallet.address(),
    token: "ETH",
    amount: ethers.utils.parseEther("0.00000000000001"),
  });

  console.log(deposit);

  console.log(await deposit.awaitReceipt());

  console.log(await deposit.awaitVerifyReceipt());
}

{
  executed: true,
  block: { blockNumber: 5090, committed: true, verified: false }
}

アカウントのアンロック

if (!(await syncWallet.isSigningKeySet())) {
  if ((await syncWallet.getAccountId()) == undefined) {
    throw new Error("Unknown account");
  }

  const changePubkey = await syncWallet.setSigningKey({ feeToken: "ETH" });

  await changePubkey.awaitReceipt();
}

実行しても次のエラーが出る

ZKSyncTxError: zkSync transaction failed: Not enough balance
    at Transaction.<anonymous> (/Users/odan/source/github.com/odan-sandbox/zksync-sandbox/node_modules/zksync/build/wallet.js:619:36)

    executed: true,
    success: false,
    failReason: 'Not enough balance',
    block: { blockNumber: 5178, committed: true, verified: false }
  }
}

アカウントの状態を見る

const { syncWallet } = await getProviderAndWallet(MNEMONIC);

const state = await syncWallet.getAccountState();

console.log({ state });

{
  state: {
    address: '0x13fcd5b4348fefe49aacf98275cbd9f5f2a2acd2',
    id: 6722,
    depositing: { balances: {} },
    committed: {
      balances: [Object],
      nonce: 1,
      pubKeyHash: 'sync:00b0ee1b1934ac8f606bceaebb6ffaf2ae520ee1'
    },
    verified: {
      balances: [Object],
      nonce: 1,
      pubKeyHash: 'sync:00b0ee1b1934ac8f606bceaebb6ffaf2ae520ee1'
    }
  }
}

zkSync 上で ETH を転送

const amount = zksync.utils.closestPackableTransactionAmount(
  ethers.utils.parseEther("0.01"),
);
console.log({ amount });

// 0xd2820FA24B72D7d25DE2C932dC40b10b0536e06C
console.log(syncWallet2.address());

const transfer = await syncWallet.syncTransfer({
  to: syncWallet2.address(),
  token: "ETH",
  amount,
});
console.log({ transfer });

const transferReceipt = await transfer.awaitReceipt();
console.log({ transferReceipt });

Ethereum に引き出す

// 0xd2820FA24B72D7d25DE2C932dC40b10b0536e06C
console.log(syncWallet2.address());
const withdraw = await syncWallet2.withdrawFromSyncToEthereum({
  ethAddress: ethWallet2.address,
  token: "ETH",
  amount: ethers.utils.parseEther("0.001"),
});

console.log({ withdraw });

console.log(await withdraw.awaitReceipt());

console.log(await withdraw.awaitVerifyReceipt());

{
  value: {
    executed: true,
    success: false,
    failReason: 'Account is locked',
    block: { blockNumber: 5180, committed: true, verified: false }
  }
}
