# Trx

This is a generic method for invoking JSON RPC's `eth_sendTransaction` with Ethers.js. Use this method to create a transaction that invokes a smart contract method. Returns an Ethers.js `TransactionResponse` object.

* `address` (string) The Ethereum address the transaction is directed to.
* `method` (string) The smart contract member in which to invoke.
* `[parameters]` (any\[]) Parameters of the method to invoke.
* `[options]` (CallOptions) Options to set for `eth_sendTransaction`, (as JSON object), and Ethers.js method overrides. The ABI can be a string optional ABI of the single intended method, an array of many methods, or a JSON object of the ABI generated by a Solidity compiler.
* `RETURN` (Promise\<any>) Returns an Ethers.js `TransactionResponse` object or an error object if the transaction failed.

```
const oneEthInWei = '1000000000000000000';
const sEthAddress = '0x4ddc2d193948926d02f9b1fe9e1daa0718270ed5';
const provider = window.ethereum;

(async function() {
  console.log('Supplying ETH to the Belugas Loan...');

  // Mint some aBNB by supplying ETH to the Belugas Loan
  const trx = await Belugas.eth.trx(
    sEthAddress,
    'function mint() payable',
    [],
    {
      provider,
      value: oneEthInWei
    }
  );

  // const result = await trx.wait(1); // JSON object of trx info, once mined

  console.log('Ethers.js transaction object', trx);
})().catch(console.error);
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.belugas.io/aquarius.js/ethereum-methods/trx.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
