Unlock is a protocol for memberships that enables creators to monetize their work on their own terms, without relying on third-party applications or platforms. As a creator, you can monetize your work and ensure that only your members can access it by creating a Lock. The Lock is a smart contract deployed on the Ethereum blockchain that defines the terms of your membership. It is owned by you and cannot be modified by anyone else unless you grant them permission. The Lock is independent of the content or features it locks and can be implemented in various contexts, such as on the front-end, back-end, chat applications, or other smart contracts. As consumers, you can easily unlock access to your favorite websites or become part of communities through Unlock's Non-Fungible Tokens (NFTs). These tokens are directly linked to your Ethereum wallet. Unlock has also developed a keychain for consumers to manage their memberships conveniently. This includes canceling, transferring, or printing codes to assert ownership.
