NFT.scribe: Bridging the NFT Multiverse on Telos

NFT.scribe is a versatile Telos C++ smart contract designed to bridge the realms of Non-Fungible Tokens (NFTs) across different networks. Through a series of specialized modules, the contract enables users to register NFTs, manage cross-chain NFT details, and engage with oracle-driven post actions. Coupled with a user-centric approach, it provides network management features and fosters an integrated ecosystem for NFT aficionados and developers alike. Our contract ensures a seamless experience for interoperability and functionalities vital for the thriving NFT community on the Telos platform.

TODO List:

Future Advancements

Things to consider, if successfully deployed:

• Premium user names (uint128_t secondary key) for each network, ownership of the premium name exists as NFT on network_id chain
• Transaction fee implementation option to turn on if needed
• Possibility to increase nft_qty in nftservice.hpp

Interchain NFT's Formats

Username Convention for Interchain NFT's

Example: [email protected]

Technical formatting: std::string sName = name("xxxxx.suffix").to_string() + "@" + name("eth.mainnet");

• Basic format: [email protected]
• xxxxx allows for registration of #0 to #28,629,150 NFT accounts under one registration, more than needed.
• suffix allows for 887,503,681 NFT service registrations for different NFT projects.
• @ used as a separator between the user and the network they operate on, like an email address.
• eth.mainnet specifies the network_id the user is operating on

Nft Service Registration Billing

• 1. Billing for registration happens inside _nftregister(...) which is called by Telos Native ACTION nftregister(...) or by oracles through ACTION post(...)
• 2. name &auth will have their deposit account billed to pay for the NFT Service Registration
