# Ethereum Types

## `Ethereum.Tx`

A transaction to execute, with the account that pays for it.

Supply the fields directly, or the encoded transaction under `serialized` when replaying one off the wire.

`from` is authoritative. The engine takes the sender alongside a signature-stripped envelope rather than recovering it, so a signature the envelope carries is never read and never checked against `from`.
