Etherless is the Mobby token, a lockable token based on the OpenZeppelin Library which features the ability to transact without holding any ethereum to pay for gas.

Project for the Master's course Blockchain and Decentralized Applications at the BUT FIT. This project aims at practicing the activities typically associated with the creation of blockchain application on EVM (Ethereum Virtual Machine) compatible platform (such as Ethereum, Polygon, Hyperledger Besu, etc.). The project starts creating a smart contract in Solidity language that implements ERC20 token with extended functionality. The assignment also includes the implementation of a dApp that allows convenient interaction with the contract using a graphical interface.

Introduction to blockchain development

A blockchain decentralized app developed using Solidity and Vite, where users can create their own zombie.

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.
