FlowGuard supports four wallet connectors. All of them must be able to sign CashScript transactions, including covenant inputs. The previous mainnet.cash testing-wallet path was removed because it cannot sign covenant inputs.

​
Paytaca

Chrome extension and mobile wallet, connected over a native bridge (not WalletConnect). When the wallet picker modal opens, the app probes window.paytaca for 1.5 seconds:
  • If the extension is detected, the row shows a green Detected pill.
  • If nothing responds in 1.5 seconds, the row shows a yellow Not installed pill and the Connect button becomes an Install link to the Chrome Web Store.
Paytaca covers both the desktop extension and the Paytaca mobile app.

​
Cashonize

Browser wallet, connected over WalletConnect v2. No detection probe is needed - WalletConnect handles the handshake and the wallet selection happens inside the WalletConnect modal.

​
WalletConnect

Generic WalletConnect v2 transport for Zapit and Selene mobile.
Paytaca does NOT use WalletConnect. It has a native bridge through window.paytaca. Pick Paytaca from its own row, not from WalletConnect.
WalletConnect requires a project ID at build time: 
VITE_WALLETCONNECT_PROJECT_ID=your_project_id_here
The hardcoded demo fallback was removed. If VITE_WALLETCONNECT_PROJECT_ID is missing, the connector throws a clear error at connect time instead of silently using a shared demo project.

​
WizardConnect (beta)

BCH-native Nostr relay transport, built on @wizardconnect/dapp and @wizardconnect/core. Currently supports Paytaca mobile only. Gated by an env flag at build time: 
VITE_ENABLE_WIZARDCONNECT=true
The WizardConnect protocol does NOT expose bch_signMessage. SIWX login will throw on this connector until the upstream relay lands signMessage. Use Paytaca, Cashonize, or WalletConnect if you need SIWX login.
