Cross-Chain NFT Exchange via Escrowed Fungible Token Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain systems face challenges in facilitating secure and efficient cross-chain transactions of nonfungible tokens (NFTs) due to the lack of visibility and transactional complexity across different blockchain networks.
Innovation Solution
A computer-implemented method and system for blockchain cross-chain NFT exchange, which involves holding an NFT in a first escrow digital wallet on a first blockchain network, monitoring the balance of fungible tokens transferred from a second blockchain network, and upon reaching the trade value, simultaneously transferring the NFT to the buyer's wallet and the fungible tokens to the seller's wallet, utilizing a cross-chain communications network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If cross-chain NFT transactions are facilitated without escrow mechanisms, then transaction speed is improved, but security and reliability deteriorate due to lack of visibility and trust between chains
Solution Approach 1:
The patent introduces escrow digital wallets as intermediary components that hold NFTs and fungible tokens during cross-chain transactions. These escrow wallets act as trusted mediators between buyer and seller, ensuring that assets are securely held until transaction conditions are met, thereby resolving the trust and security issues in cross-chain NFT exchanges
2Productivity
If simultaneous transfer of NFT and fungible tokens is implemented, then transaction efficiency is improved, but system complexity worsens due to coordination requirements across multiple blockchains
Solution Approach 1:
The patent employs preliminary actions by first transferring the NFT to the buyer's wallet and initiating the fungible token transfer process before the actual exchange is complete. The escrow system prepares and monitors the fungible token balance in advance, enabling coordinated simultaneous completion of both asset transfers while managing the complexity through structured transaction workflows
3Adaptability or versatility
If cross-chain communications network is used for NFT exchange, then adaptability is improved, but loss of information worsens due to visibility limitations across different blockchain networks
Solution Approach 1:
The patent implements feedback mechanisms where the escrow system continuously monitors the balance of fungible tokens transferred from the second blockchain network. This feedback loop ensures that transaction conditions are verified and that the NFT transfer is triggered only when the trade value is met, preventing information loss and ensuring transaction integrity across chains

AI summary
Systems and methods exchange a nonfungible token (NFT) via blockchain cross-chain fungible token transfers using first and second blockchains. The first blockchain holds the NFT in a first escrow digital wallet. The NFT is available for trade by a seller and is associated with a trade value. The first blockchain monitors a balance of fungible tokens, owned by a buyer, that are transferred from a second blockchain to a second escrow digital wallet of the first blockchain. In response to detecting that the balance monitored represents the trade value, the first blockchain transfers, simultaneously, (i) the NFT from the first escrow digital wallet to a first digital wallet of the first blockchain, the first digital wallet owned by the buyer, and (ii) the balance of fungible tokens from the second escrow digital wallet to a second digital wallet of the second blockchain, the second digital wallet owned by the seller.
