Typescript Example with Aptos SDK

First install the Aptos Typescript SDK. You can find the full documentation here: https://aptos.dev/en/build/sdks/ts-sdk

Here a code sample to broadcast a transaction via the Dfns TypeScript SDK:

import {
  Aptos, 
  APTOS_COIN, 
  AptosConfig, 
  MimeType, 
  Network, 
  PendingTransactionResponse, 
  postAptosFullNode
} from '@aptos-labs/ts-sdk'


const walletId = 'wa-6lbfv-9esgj-88s80c0qsih0a393'
const wallet = await dfnsClient.wallets.getWallet({ walletId })

const myAddress = new PublicKey(wallet.address)
const toAddress = new PublicKey('0x5bdc24cb9033286ffe19f436145b9e2267dd03b0fd0d422459d381a6431d39ba')

const aptosConfig = new AptosConfig({
    network: Network.TESTNET,
  })
const client = new Aptos(aptosConfig)

const transaction = await client.transaction.build.simple({
    sender: wallet.address,
    data: {
      function: '0x1::coin::transfer',
      typeArguments: [APTOS_COIN],
      functionArguments: [
        "0x5bdc24cb9033286ffe19f436145b9e2267dd03b0fd0d422459d381a6431d39ba",
        "1",
      ],
    },
  })

const res = await dfnsClient.wallets.broadcastTransaction({
  walletId,
  body: {
    kind: 'Transaction',
    transaction: transaction.bcsToHex().toString(),
  },
})
