Create a Block Zero wallet

🔒 Everything happens in your browser

• Your private key is generated locally, using your device's secure random generator (crypto.getRandomValues).
• It is never sent to the pool or any server. This page makes zero network requests — enforced by a Content-Security-Policy of connect-src 'none', so it is literally incapable of phoning home.
• It works offline. Disconnect your internet first if you like, or save this page and open it on an air-gapped machine.
• It is open source. The key math is a few short, readable files: wallet-lib.js · app.js · vendor.js (audited noble/scure crypto).
• The address & key are compatible with the native BlockZero Core wallet (standard compressed WIF + wpkh() descriptor) — verified against the node.
