Unlock is a no-code tool for creating and managing memberships.

What is Unlock ?
Unlock is a smart contracting system that has been creating time-bound memberships as NFTs since 2018. It is the only smart contract protocol specifically built for memberships, with built-in support for expirations, renewals, and recurring onchain payments. Unlock enables easy onboarding through email-based memberships, walletless airdrops, and integration with Apple Wallet and Google Wallet. The protocol is open-source, fully audited, and used by over 5,000 developers and community members across Ethereum, Polygon, Arbitrum, Avalanche, BNB Chain, and Optimism.
