How to play casino games straight from a crypto wallet with wallet-connect?
Wallet-connect is a protocol that links a crypto wallet to a web application without the wallet’s private key ever leaving the device. A player does not enter credentials into the casino. Instead, the wallet and the casino establish a session through an encrypted bridge, and transactions that require signing are sent to the wallet for approval.
Connecting through https://crypto.games/ starts with a QR code or deep link that the wallet scans or opens. Once the session is active, deposits, bet confirmations, and withdrawals that require on-chain interaction are routed through the wallet rather than processed by a stored account balance alone.
How is the connection established?
Opening the connection requires a wallet that supports the wallet-connect standard. Most non-custodial wallets have added this support. A player visits the casino’s connection page, selects wallet-connect as the login or connection method, and the casino generates a pairing code.
- Scanning the QR code with the wallet app opens a pairing request that shows which application is requesting access and what permissions are involved.
- Confirming the pairing in the wallet completes the connection without the casino receiving any account credentials or seed phrase.
- Active connections appear in the wallet’s session list, where they can be reviewed or disconnected at any time without accessing the casino directly.
What does the wallet approve during play?
Once connected, gameplay that involves on-chain transactions routes each action through the wallet for signature. A deposit requires the player to approve a transaction from the wallet. That approval is shown in the wallet interface with the destination address and the amount, and the player confirms or rejects it before anything is broadcast.
Games built entirely on smart contracts require a signed transaction for each bet. The wallet prompt appears, the player reviews the bet amount and the contract address, and confirmation sends the transaction to the blockchain. Games that use an off-chain balance layer process bets internally, with only deposits and withdrawals requiring wallet signatures. Players should check which model applies to a specific game, as the frequency of wallet prompts differs considerably between the two.
Session management and permissions
A wallet-connect session grants the casino permission to send transaction requests to the wallet. It does not grant the casino permission to move funds independently. Every transaction still requires an explicit approval from the player within the wallet interface. No funds can leave the wallet without that confirmation step.
Sessions remain active until the player disconnects them. Disconnecting from the casino interface ends the session, but the wallet’s own session management panel may list the connection separately. Ending the session from both sides ensures the pairing is fully closed. Leaving an active session open on an unlocked device creates a situation where someone with physical access to the device could approve transactions without needing wallet credentials.
Wallet compatibility and chains
Wallet-connect supports multiple blockchains, and the casino must operate on the same chain as the connected wallet for transactions to function. A wallet connected to one chain cannot sign transactions for a casino operating on a different chain without switching networks first. Players should confirm which networks the casino supports before initiating the connection. Wallets that support multiple networks allow switching inside the wallet interface. Connecting on the wrong network produces failed transaction attempts rather than error messages at the pairing stage, which can create confusion about where the issue originates. Selecting the correct network before scanning the pairing code avoids this entirely.
Wallet-connect play keeps the approval step on the player’s device throughout the session, which separates it structurally from account-based logins, where funds are held and moved by the casino without individual transaction confirmation.
