Our team has already developed an ERC-1155 NFT system to be used by event creators, vendors and end users for trading both online and offline. This system can be used by any industry for trading and redemption through blockchain.
The system is Redeemable, Tradable, Scalable and Trustless.
Redeemable - Redemption of online/offline products by customers (end users). Vendors can execute settlement on blockchain directly without going through any third parties.
Tradable - ERC-1155 NFTs can be traded on secondary market (Opensea)
Scalable - The system is deployed on Polygon Chain, which supports large events with minimum gas fee impact.
Trustless - Before event creator wants to create (mint) the NFTs, they need to decide the quantity and value, after which the contract requires the creator to deposit the agreed value for the creation. Vendors do not need to deal with creator for settlement. They only need to execute settlement via the smart contract.
