- **from** – the sender’s address (required).

- **gas** – maximum amount of gas units allowed for execution.
- **gasPrice** – price per unit of gas (legacy gas pricing).
- **maxFeePerGas** – maximum total fee per gas (EIP-1559).

- **value** – amount of wei to send (use hex string).
- **data** – ABI-encoded call data (for contract interaction).
