Barjbet is currently accessible through Farcaster frames only, and this dApp is not standalone.
It serves as an extension of the BarjBet frames, allowing you to sign transactions if you encounter difficulties with in-frame transactions.
For example, if you want to use MetaMask on mobile instead of Coinbase Wallet, which is currently the only supported wallet.
You will find a button linking to this app whenever an on-chain transaction is needed.
