## Use Case

The `eth_sendRawTransaction` method is essential for:

* Submitting signed transactions to the network
* Wallet transaction broadcasting
* DeFi protocol interactions
* Token transfers
* Smart contract deployments
* High-frequency trading on Monad

## Error Handling

    value: ethers.parseEther('1.0'),
    gasLimit: 21000
};

const txResponse = await wallet.sendTransaction(tx);
console.log('Transaction hash:', txResponse.hash);

// Wait for confirmation (fast on Monad!)
const receipt = await txResponse.wait();
console.log('Confirmed in block:', receipt.blockNumber);
