Coinbase Wallet is a self-custody crypto wallet developed by Coinbase, and it holds a distinct position in the wallet ecosystem because of the brand recognition and trust that the Coinbase name carries among both experienced crypto users and newcomers to the space. Unlike the Coinbase exchange app, Coinbase Wallet is a self-custody product where the user controls their own private keys. It supports Ethereum, Solana, Bitcoin, Polygon, Base, Avalanche, and other networks, and its user base includes a substantial segment of first-time crypto holders who chose the wallet because of its association with one of the most recognized names in the industry.
For merchants accepting cryptocurrency payments, integrating Coinbase Wallet into the checkout means reaching this user base through a wallet connection that feels familiar and trusted to users who may be less comfortable with crypto transactions than the typical MetaMask or Phantom user. The onboarding advantage of Coinbase Wallet's brand makes it particularly valuable for merchants whose customer base includes people paying with crypto for the first time.
27 Blockchain provides Coinbase Wallet integration as part of its crypto payment infrastructure for merchants. The integration connects the merchant's checkout to Coinbase Wallet through APIs and SDKs, allowing customers to pay directly from their Coinbase Wallet at the point of purchase across e-commerce, custom platforms, and point-of-sale environments.
Integrating Coinbase Wallet into a merchant's payment system requires building a connection between the checkout and the Coinbase Wallet browser extension or mobile app. Coinbase Wallet supports WalletConnect as a connection protocol, which means it can connect to merchant checkouts through QR code scanning on desktop or deep linking on mobile. The integration generates a payment request specifying the amount, the token, the network, and the destination address, and the customer reviews and approves the transaction inside the Coinbase Wallet interface.
Coinbase Wallet's multi-chain support means the integration can accept payments on Ethereum, Solana, Base, Polygon, and other supported networks without requiring separate integrations per chain. 27 Blockchain configures the checkout to detect which network the customer's Coinbase Wallet is connected to and routes the transaction accordingly. The technical scope covers wallet connection, transaction construction, blockchain monitoring, settlement, and the reporting layer that feeds transaction data into the merchant's system.
Merchants interested in adding Coinbase Wallet to their crypto checkout can contact 27 Blockchain to begin the integration. The consultation identifies which blockchain networks and tokens the merchant wants to accept, how the wallet connection will appear in the checkout flow, and how settlement and reporting will be configured. 27 Blockchain handles the deployment from start to finish.
