Acting on a prepared transaction

Transactions have a variety of actions that can be called on them, in all cases this is done by passing the transaction to the various action functions.

Send the prepared transaction to the blockchain. Sending a transaction requires a wallet.

See Wallets for more information on how to create a wallet.

import { sendTransaction } from "thirdweb";
import { createWallet } from "thirdweb/wallets";
 
const wallet = createWallet("io.metamask");
const account = await wallet.connect({ client });
 
const transactionResult = await sendTransaction({
  transaction,
  account,
});

Send a transaction and wait for it to be mined. Useful when you want to block until the transaction is fully confirmed onchain before proceeding to the next step.

import { sendAndConfirmTransaction } from "thirdweb";
import { createWallet } from "thirdweb/wallets";
 
const wallet = createWallet("io.metamask");
const account = await wallet.connect({ client });
 
const receipt = await sendAndConfirmTransaction({
  transaction,
  account,
});

Wait for a transaction to be mined and get the transaction receipt.

import { sendTransaction, waitForReceipt } from "thirdweb";
import { createWallet } from "thirdweb/wallets";
 
const wallet = createWallet("io.metamask");
const account = await wallet.connect({ client });
 
const transactionResult = await sendTransaction({
  transaction,
  account,
});
 
const receipt = await waitForReceipt(transactionResult);

Estimating gas used by a transaction

import { estimateGas } from "thirdweb";
 
const gasEstimate = await estimateGas({ transaction });
console.log("estmated gas used", gasEstimate);

Estimating gas cost in ether and wei for a transaction

import { estimateGas } from "thirdweb";
 
const gasCost = await estimateGasCost({ transaction });
console.log("cost in ether", gasCost.ether);

Simulate a transaction to see if it would be successful.

import { simulateTransaction } from "thirdweb";
 
const result = await simulateTransaction({ transaction });
console.log("simulation result", result);

Encode a transaction data to be used later

import { encode } from "thirdweb";
 
const data = await encode(transaction);
console.log("encoded data", data);
