Which wallet does the marketplace work with?

The Creta Wallet browser extension, on Chrome or another Chromium-based browser. Press Connect Wallet and approve the request in the extension; if it is not installed, the site offers you the install link instead.

Two related cases:

• Inside the Creta Games & Clubs desktop app, the marketplace uses that app's own built-in wallet — the browser extension cannot run there.
• On a phone, a browser extension cannot be installed at all. Use the Creta mobile app.

The extension, the desktop app's wallet and the mobile wallet are separate wallets. Import the same seed phrase into each if you want one address everywhere.
