# Build a Passkey Powered Guestbook Dapp

> This section walks you through designing and building a decentralized application (dapp) that interacts with a smart contract guestbook, allowing users to read and write public messages. The tutorial also implements a passkey-powered smart wallet for user authentication.

That smart wallet is built with [Smart Account Kit](https://github.com/stellar/smart-account-kit) and the [OpenZeppelin Smart Account](https://docs.openzeppelin.com/stellar-contracts/accounts/smart-account) contracts, and its transactions are submitted by the [OpenZeppelin Relayer](https://docs.openzeppelin.com/relayer/guides/stellar-channels-guide) running the Stellar Channels plugin.
