GNS · Offline Architect

Build Claim PSBTs Offline

This single-file tool prepares Global Name System claim artifacts entirely in your browser. Paste the wallet metadata and UTXOs you already trust, then carry the resulting PSBTs into Sparrow for signing.

What This Does

Builds the claim package, commit PSBT, reveal PSBT, and reveal-ready package without sending your inputs to a hosted service.

What You Still Need

Name availability checks, wallet UTXO discovery, and final signing still happen outside this file. That separation is intentional.

Security Model

The website is only the architect. Your wallet stays the key guardian and authorizer.

Claim Inputs

Paste the exact name, owner pubkey, wallet metadata, and confirmed UTXOs you want this offline architect to use.
