如何创建和发送Flashbot bsc？

Question

我试图赎回一些在元询问中丢失的ERC令牌，我从Flashbots https://github.com/flashbots/searcher-sponsored-tx中找到了这段代码

原来我的令牌在bsc网络上，我对代码做了一些更改，但没有成功，我的更改：

const ETHEREUM_RPC_URL = process.env.ETHEREUM_RPC_URL || "https://bsc-dataseed1.binance.org:443"
   const provider = new providers.StaticJsonRpcProvider(ETHEREUM_RPC_URL);
   const flashbotsProvider = await FlashbotsBundleProvider.create(provider, walletRelay);

但是，如果没有成功，在bsc链中是否有使用此方法的方法？

Answer 1

在撰写本报告时(2022年5月)，geth矿工和Flashbot rpc端点仅在endpoint和Goerli测试网(https://docs.flashbots.net/flashbots-auction/searchers/quick-start)上可用。

你可以试着这样做：

const PRIVATE_KEY_EXECUTOR = process.env.PRIVATE_KEY_EXECUTOR || "XXXXXX"
const PRIVATE_KEY_SPONSOR = process.env.PRIVATE_KEY_SPONSOR || "XXXXXX"
const FLASHBOTS_RELAY_SIGNING_KEY = process.env.FLASHBOTS_RELAY_SIGNING_KEY || "XXXXXX";
const RECIPIENT = process.env.RECIPIENT || "XXXXXX"

[....]

  const ETHEREUM_RPC_URL = process.env.ETHEREUM_RPC_URL || "https://bsc-dataseed.binance.org/"
  const provider = new providers.StaticJsonRpcProvider(ETHEREUM_RPC_URL);
  const flashbotsProvider = await FlashbotsBundleProvider.create(provider, walletRelay);

[...]


  const tokenAddress = "CONTRACT_ADDRESS_HERE";
  const engine: Base = new TransferERC20(provider, walletExecutor.address, RECIPIENT, tokenAddress);

然后在bundleTransaction:内部指定事务配置。

希望能帮上忙。
