# 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 Strike Protocol...');

  // Mint some sETH by supplying ETH to the Strike Protocol
  const trx = await Strike.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);
