Introduction
The Token Manager program is a wrapper protocol that achieves conditional ownership of Solana NFTs. It allows one to issue an NFT to another party with embedded mechanisms for programmatic management of the token while it sits in their wallet. Among others, things like time-based expiration, usage-based expiration, selective transferability, and non-transferability are possible with the Token Manager. Its modular design uses “plugin” invalidators, approval authorities, and transfer authorities modeled as separate smart contracts to allow for theoretically any custom invalidation, claiming, and transfer logic tied to on-chain data. We currently offer two out-of-the-box invalidator plugins to support basic time and usage-based expiration as well as a basic payment-based claim approver. The Token Manager is the sun around which the rest of our protocol and product suite revolves. Read on to learn more!
