Experimental
Bitcoin Experiments
This page contains exploratory Bitcoin wallet, Taproot, and Silent Payments work. It is not part of the core MLWR control-desk workflow and should not be used for production custody, settlement, or regulated operations without independent review.
Resolved Taproot wallet balance.
OpenETR
Check Bitcoin Balance
Resolve an nsec, npub, NIP-05 identifier, or a bare domain such as
example.com. The app derives the canonical Taproot p2tr address and looks up its
balance through the configured Esplora API.
Check Silent Payment Ownership
Check whether a Silent Payment address belongs to an npub or the npub resolved from a
NIP-05 identifier. Leave the Silent Payment address blank to generate and display the derived
sp1... address for that identity.

This Silent Payment address can be shared with compatible wallets. OpenETR can now check a provided Bitcoin txid for a matching receipt and preview a sweep transaction, but broad wallet-style scanning and richer UX are still under implementation.
