Send Transaction Overview

We will go over how you can use the Push Chain SDK to send transactions to the network.

Send Transaction API

js

const tx = await pushChain.tx.send(
  [
    // Defaults to the Ethereum Sepolia chain
    createUniversalAccount({
      address: '0x22B173e0596c6723dD1A95817052D96b97176Dd8',
    }),
  ],
  {
    category: 'MY_CUSTOM_CATEGORY',
    data: 'Hello world',
  }
);

react

const tx = await pushChain.tx.send(
  [
    // Defaults to the Ethereum Sepolia chain
    createUniversalAccount({
      address: '0x22B173e0596c6723dD1A95817052D96b97176Dd8',
    }),
  ],
  {
    category: 'MY_CUSTOM_CATEGORY',
    data: 'Hello world',

reactnative

const tx = await pushChain.tx.send(

Example: send an email to a Solana address

Here below is an example of sending an Email to a Solana address. The payload is a simply JSON object with a title and message.

const tx = await pushChain.tx.send(
  // We will send the transaction to a Solana address
  [
    createUniversalAccount({
      chain: CONSTANTS.CHAIN.SOLANA,
      chainId: CONSTANTS.CHAIN_ID.SOLANA.DEVNET,
      address: 'ySYrGNLLJSK9hvGGpoxg8TzWfRe8ftBtDSMECtx2eJR',
    }),
  ],
  {
    category: 'MY_EMAIL_APP',
    // Sample email payload
    data: JSON.stringify({
      title: 'Hello old friend from Solana!',
      message: 'Greetings from Ethereum world.',
    }),
  }
);
