monero-serai: make it clear that not providing a change address is fingerprintable (#472) 
* Make it clear not providing a change address is fingerprintable

When no change address is provided, all change is shunted to the
fee. This PR makes it clear to the caller that it is fingerprintable
when the caller does this.

monero-serai

A modern Monero transaction library intended for usage in wallets. It prides itself on accuracy, correctness, and removing common pit falls developers may face.

monero-serai also offers the following features:

  • Featured Addresses
  • A FROST-based multisig orders of magnitude more performant than Monero's

Purpose and support

monero-serai was written for Serai, a decentralized exchange aiming to support Monero. Despite this, monero-serai is intended to be a widely usable library, accurate to Monero. monero-serai guarantees the functionality needed for Serai, yet will not deprive functionality from other users.

Various legacy transaction formats are not currently implemented, yet we are willing to add support for them. There aren't active development efforts around them however.

Caveats

This library DOES attempt to do the following:

  • Create on-chain transactions identical to how wallet2 would (unless told not to)
  • Not be detectable as monero-serai when scanning outputs
  • Not reveal spent outputs to the connected RPC node

This library DOES NOT attempt to do the following:

  • Have identical RPC behavior when creating transactions
  • Be a wallet

This means that monero-serai shouldn't be fingerprintable on-chain. It also shouldn't be fingerprintable if a targeted attack occurs to detect if the receiving wallet is monero-serai or wallet2. It also should be generally safe for usage with remote nodes.

It won't hide from remote nodes it's monero-serai however, potentially allowing a remote node to profile you. The implications of this are left to the user to consider.

It also won't act as a wallet, just as a transaction library. wallet2 has several non-transaction-level policies, such as always attempting to use two inputs to create transactions. These are considered out of scope to monero-serai.
