Know exactly how much privacy each Bitcoin transaction spends.
A policy engine for wallet teams: declare which UTXO clusters must never merge, and get coin selection that respects it, with an auditable fee cost for every tradeoff.
Who it is for
Engineers maintaining coin selection in Bitcoin wallets (BDK-based or custom) who want privacy rules that are explicit, testable and explainable to users.
What it will do
Declare privacy policies (e.g. never merge KYC and non-KYC coins) as code
See the extra fee each policy costs, per transaction, with bounds you can audit
Run locally as an open evaluator against your wallet's real UTXO sets
