Yes! The Magic Eden Wallet should work on all dApps on Bitcoin, Solana, Ethereum, and Polygon. If you don't see Magic Eden Wallet as an available option in the connect wallet flow, go to the account tab (last tab), click settings, and toggle on "Prioritize Magic Eden." Hard refresh on the site that you're on. The prioritize function will allow you to inject the Magic Eden Wallet over other providers.
The injection will only work for MetaMask on Ethereum and Polygon, Xverse for Bitcoin, and Phantom for Solana. We are continuing to work with more dApps to make it easy for you to login to any dApp in the ecosystem.
