Transaction Receipts: Transactions return receipts indicating success or failure. Failed receipts are generated without transaction execution. Successful Transaction Response: A successful transaction provides a SentTransactionResponse. Always verify this response with the isSentTransactionResponse type guard before accessing the transaction hash. 
import { Sequence, isSentTransactionResponse } from "@0xsequence/waas";

const waas = new SequenceWaaS(
  {
    projectAccessKey: `${process.env.PROJECT_ACCESS_KEY}`,
    waasConfigKey: `${process.env.WAAS_CONFIG_KEY}`,
    network: "arbitrum-nova",
  }
);

await waas.signIn({ idToken }, "Session name");

const tx = await waas.sendTransaction({
  chainId: 42161,
  transactions: [
    {
      to: "0xD72C236Be524Ec24F72329317e2785E687105B69",
      value: "0",
    },
  ],
});

if (isSentTransactionResponse(tx)) {
  console.log(tx);
}
Understanding Transaction Details Fields in Transaction Responses:
  • txHash: The hash of the transaction sent to the network.
  • receipt.logs: Logs emitted during the transaction.
  • receipt.status: Indicates if the transaction SUCCEEDED or FAILED.
  • receipt.revertReason: Explains why a transaction was reverted, if applicable.

Failed transaction response

An In-Game Wallet pre-empts failing transactions by simulating them on the network before actual submission. If the simulation fails, the transaction is not sent, and a FailedTransactionResponse is returned. 
import { Sequence, isSentTransactionResponse } from "@0xsequence/waas";

const waas = new SequenceWaaS(
  {
    projectAccessKey: `${process.env.PROJECT_ACCESS_KEY}`,
    waasConfigKey: `${process.env.WAAS_CONFIG_KEY}`,
    network: "arbitrum-nova",
  }
);

await waas.signIn({ idToken }, "Session name");

const tx = await waas.sendTransaction({
  chainId: 137,
  transactions: [
    {
      // This address always fails on Polygon, give it a try :D
      to: "0x839eE023B21f4Ffe2294025DE0AC30Ba7278D6Fd",
      value: "0",
    },
  ],
});

if (isSentTransactionResponse(tx)) {
  // ... This will never be executed
} else {
  // tx can only be `SentTransactionResponse` or `FailedTransactionResponse`
  console.log(tx);
