These wallets are specifically designed to interact with the Celo blockchain and provide a user-friendly interface for managing Celo accounts and transactions.

  2. Wallet Connect Protocol: React-Celo utilizes the Wallet Connect protocol, a widely adopted standard for establishing secure connections between dApps and mobile wallets. This protocol allows the dApp to securely communicate and interact with the user’s wallet using encrypted QR code scanning or deep linking.

  3. Connecting to the Wallet: When a user accesses a React-Celo dApp, they are presented with a wallet connection button or QR code that initiates the wallet connection process. When the user interacts with this button or scans the QR code using their Celo-compatible mobile wallet, a secure connection is established between the dApp and the wallet.

  4. Secure Authentication: The wallet connectivity process includes a secure authentication mechanism to ensure that the user is granting permission for the dApp to access their Celo account. This authentication step typically involves verifying a digital signature generated by the user’s wallet using their private key.

  5. Accessing Account Information: Once the wallet connection is established, React-Celo can access the user’s Celo account information, such as the account address and public key. This information allows the dApp to perform actions on behalf of the user and retrieve account-specific data, such as balances or transaction history.

  6. Transaction Signing: When the user initiates a transaction within the React-Celo dApp, such as sending tokens or interacting with a smart contract, the transaction details are securely signed by the user’s mobile wallet. This ensures that the transaction is authorized by the user and prevents any tampering or unauthorized actions.

  7. Confirmation and Broadcasting: After the transaction is signed by the user’s wallet, React-Celo receives the signed transaction and confirms its validity. The dApp then broadcasts the signed transaction to the Celo network for processing and inclusion in the blockchain.

  8. User Experience: React-Celo simplifies the user experience by handling the wallet connectivity process and providing feedback to the user at each step. This includes displaying connection status, requesting authorization for transactions, and providing transaction confirmation messages.

By leveraging Celo-compatible wallets and the Wallet Connect protocol, React-Celo eliminates the need for users to manually enter private keys or seed phrases. This enhances security by keeping sensitive information within the user’s wallet and improves usability by providing a familiar and trusted wallet interface for interacting with Celo dApps.

d. Celo-specific Components: React-Celo offers a range of components tailored specifically for Celo dApps, such as QR code readers for scanning payment requests, transaction history views, and token balance displays.
