Spectrr Finance Smart Contracts

Omnisea NFT Drops core contracts deployable on zkSync.

A test project given by a stealth startup to validate ✍️ my smart contract skills. The task was to create a gasless marketplace 🛒. The sellers can list the NFT for sale against a specified no of ERC-20 token called GEM's 💰 and whitelist some buyers.

So the whitelisted buyers will be able to transfer the required GEM's 💰 and buy's the NFT. And other task was to allow user to burn their ERC-721 token to upgrade to ERC-1155 token.

Furthermore, gasless ⛽ transaction is also implemented using ERC-2771. The relay is created using NodeJS, and it also tracks the amount of gas spend in a database for analytics.

This is an buildspace project for minting our own NFT. The smart contact creates a random NFT on-chain when we mint. It also has restriction to only allow 50 NFT's. The react application allows us to connect out wallet and mint NFT by calling the contract. This was a very fun project to me. Thanks to buildspace.
