Unlock dynamic NFTs in Ethereum and Polkadot

Dynamic non-fungible token (NFT) can response to real-world events and will be the next revolution in blockchain domain. RareLink Protocol creates the infrastructure for dynamic NFT, enables cross-chain transfer and powers new decentralized finance (DeFi) applications.

Dynamic NFT

The next evolution in NFTs is moving from static NFTs to dynamic NFTs— perpetual smart contracts that use oracles to communicate with and react to external data and systems. The oracle allows the NFT to use external data/systems as a mechanism for minting/burning NFTs, trading peer-to-peer, and checking state.

Digital collectibles
Digital collectibles are unique digital assets that are valuables for aspecific group of holders. These collectibles can be created as NFTs and traded between peers on blockchain network. A good example is CryptoKitties, as each digital cat is uniquely represented as a NFT and traded on Ethereum network. Moreover, these digital collectibles can be issued as NFT on specific read-world events. As such, the off-chain events can trigger the minting or burning of dynamic NFTs for unique digital collectibles. These NFTs can be easily transfer or exchange on the blockchain network.rare

Token Bridge

Most existing NFTs are created as ERC721 tokens and limited to Ethereum network. RareLink Protocol builds a new token bridge beween Ethereum and Polkadot, which unlock static and dynamic NFTs in both ecosystems. It provides more liquidity for DeFi applications and enables more business use cases.

Features

Dynamic Behavior
Different from existing static NFT, the new dynamic NFT is responsive to the real-world data or events (e.g., minting, burning, updating NFTs according to specified off-chain events)
Interoperability
Build on top of Substrare and connect to Polkadot network, which leverages the interoperability of Polkadot across different blockchains.

More Flexibility
Create dynamic NFTs in Ethereum or Polkadot network and transfer them across the blockchain networks without friction. It provide access to more liquidities in both ecosystems.
High Reliability
Design token bridge with high reliability as the top priority. Many new techniques will be created for this purpose. Users can transfer dynamic NFTs with worry-free protection.
