ERC-5643: Subscription NFT Standard
Bradley Allgood, Jason Smythe
Abstract
ERC-5643 introduces a standardized interface for subscription-based NFTs, facilitating recurring revenue and time-bound memberships on the blockchain. This standard allows creators to define subscription terms directly within the token contract, enabling automated renewal, cancellation, and expiration logic. By moving subscription management to the blockchain, ERC-5643 provides transparency and self-sovereignty for users while offering a predictable income model for content creators and service providers. The paper details the technical specifications, including the 'isExpired' and 'expiresAt' functions, which enable dApps and marketplaces to verify subscription status in real-time. This standard is positioned as a bridge between the traditional 'Software as a Service' (SaaS) business model and the decentralization of Web3, offering a scalable solution for managing digital content access and community memberships.
