const bundleTransactions = [ ....... { signedTransaction: signedTransaction } ....... ]; const signedBundle = await flashbotsProvider.signBundle(bundleTransactions); 是这样吗,其中signedTransaction怎么根据内存池的交易获取, provider.once('pending', async (txHash) => { console.log(txHash); const tx = await provider.getTransaction(txHash); // TODO 怎么获取 }); 有偿解答!!!
