WalletConnect is an open protocol that standardizes how crypto wallets communicate with decentralized applications and merchant checkout systems, and integrating it into a payment infrastructure is one of the most efficient ways to support a large number of wallets through a single connection layer. Hundreds of wallets support the WalletConnect protocol, including Trust Wallet, MetaMask mobile, Rainbow, Zerion, and many others, which means a merchant that implements WalletConnect integration gains compatibility with a broad segment of the crypto wallet market without building individual integrations for each one. 27 Blockchain provides WalletConnect integration as part of its crypto payment infrastructure for merchants, deploying the protocol-level connection that links the merchant's checkout to any WalletConnect-compatible wallet a customer uses.
WalletConnect establishes a connection between the merchant's checkout and the customer's wallet through a relay server that facilitates encrypted communication between the two endpoints. On a desktop checkout, the merchant's system generates a QR code that the customer scans with their mobile wallet app. On a mobile checkout, the connection can occur through a deep link that opens the wallet app directly on the same device. In both cases, the wallet and the checkout establish a secure session, and the transaction details are sent to the wallet for the customer to review and approve.
The protocol handles the communication layer, but the payment processing infrastructure behind it determines whether the transaction actually works in a merchant context. 27 Blockchain builds the full payment stack around the WalletConnect connection: the checkout interface that generates the connection request, the session management that maintains the wallet link through the transaction, the blockchain monitoring that tracks confirmation, and the settlement layer that records the completed payment. The WalletConnect protocol provides the pipe. 27 Blockchain builds the payment system around it.
Because WalletConnect is wallet-agnostic, the integration that 27 Blockchain deploys does not need to be updated every time a new wallet enters the market. Any wallet that implements the WalletConnect standard automatically becomes compatible with the merchant's checkout. This forward compatibility is one of the protocol's primary advantages for merchants processing through 27 Blockchain's infrastructure.
Merchants interested in adding WalletConnect support to their crypto payment checkout can contact 27 Blockchain to begin the integration. The consultation covers which blockchain networks the merchant wants to support, how the WalletConnect connection will be presented at checkout, and how settlement and transaction reporting will be configured. 27 Blockchain handles the full deployment, from protocol implementation through live payment processing.
