Available in Prizes
Description
The MetaMask Embedded Wallets Hackathon invites developers, designers, and innovators to build next-generation Web3 experiences centered on identity management and user experience. With the recent acquisition of Web3Auth by Consensys, MetaMask Embedded Wallets enable seamless, secure, and user-friendly wallet creation and recovery through familiar Web2 authentication methods, eliminating the need for seed phrase management and dramatically reducing onboarding friction.
Qualification Requirements
The app should have integrated the MetaMask Embedded Wallet SDKs (Web3Auth Plug and Play SDKs) and use social/email login for instant, seedless wallet creation and management.
The dApp should be deployed on the Solana blockchain. If opting for the cross chain track, it should be Solana + any other chain.
Use any of the following SDKs based on your platform:
Web3Auth Plug and Play Web SDK:
