Trustless purchase of an NFT on Flare using the token of another blockchain.
Layer-1 for data, Flare, has just completed a live demonstration of new interoperability functionality that is now available in beta on the network.
Using two core interoperability protocols, State Connector and Flare Time Series Oracle (FTSO), an NFT was securely purchased with the transaction taking place on another chain using another token. The demo was conducted on Flare’s canary network, Songbird, with the purchase made using DOGE and XRP tokens.
Flare’s State Connector protocols allow information, both from other blockchains and the internet, to be used securely, scalable and trustless with EVM-based smart contracts on Flare chains. In this case, it has been used to prove that a transaction has been confirmed on a non-Flare chain while confirming that the correct payment reference was included.
Flare Time Series Oracle delivers highly decentralized price and data streams to dapps on Flare, without relying on a centralized provider to bring the data on-chain. For the demonstration, it provides the live update price for NFT in the currency of the other chain.
Since Flare is an EVM-based blockchain, anything that can be accomplished on Ethereum and other EVM chains can also be accomplished on Flare. The NFTs minted in the demo are therefore standard ERC721 contracts written in Solidity and distributed on the network. The only changes required were to add methods to integrate with FTSO and the State Connector.
Hugo Philion, Flare CEO & Co-founder, said: “This demo highlights Flare’s ability to provide multiple types of secure, decentralized data on-chain to drive new functionality and potential industry use cases. The NFT demo is an example of the web3 tool Flare can unlock legacy tokens so they can be used trustlessly in dapps on the network. We’re excited to see what other application engineers can develop, leveraging the capabilities of Flare’s native interoperability protocols.”
