export default function Page() {
  return (
    <>
      <CardanoWallet />
    </>
  );
}

Chainable Transaction Builder

Intuitive APIs to create complex transactions, perform multi-sig minting, staking ADA to stake pools, and interacting with smart contracts.

Learn to build transactions

Transaction API

You can send ADA and NFTS to multiple addresses, lock and unlock from smart contracts, mint assets and stake ADA; all with a single transaction.

import { Transaction } from '@meshsdk/core';

const tx = new Transaction({ initiator: wallet })
  .sendLovelace('addr_a...ab', '1000000')
  .sendAssets('addr_b...cd', [{unit: 'asset...ef', quantity: '1'}])
;

const unsignedTx = await tx.build();
const signedTx = await wallet.signTx(unsignedTx);
const txHash = await wallet.submitTx(signedTx);
