Crypto & NFTs

October 2021 - January 2023

Late 2021, I joined an autonomous development team that brought together individuals with diverse skill sets, with the goal of developing ideas and software that combine Web2 and Web3 technologies.

Responsibilities

I developed web apps with a focus on user interface and user experience, creating fully tailored and responsive designs.

I integrated Blockchain wallets and interacted with Ethereum Smart-Contracts (ERC-721 and ERC-1155). I had the opportunity to work with NFT Metadata, NFT-related algorithms, IPFS technology and also learn Solidity fundamentals, programming language for Ethereum Smart-Contracts.

Tech stack

I learned through many different resources, including Alchemy (Web3 University) and the University of Nicosia, which had launched several courses on Blockchain and NFTs.

Next.js

React

TypeScript

Solidity

Wagmi ethers

Ethers.js

MetaMask

Vercel

NFTs Assets Customization

One of the most creative works I have developed consists of a web interface that allows the user to customize a Sneaker, then instantly mint it on the Blockchain as an NFT (ERC-721).

Customization

“name”: “Sneaker”,
“description”: "Customized...”,
“attributes”: [
{ “trait_type”: “...NFT Metadata

IPFS Operations

Token Minting

Crypto Sending Interface

Another interesting project I worked on is a web-interface to send cryptocurrencies, specifically Ethereum, Binance Coin and Matic, relying on MetaMask wallet integration.

Ethereum

BNB

Matic

Ens

The interface provides the user with the following information and features:

Current wallet address
ENS Domain linked (Ethereum Name Service, if any)
Balance in crypto and equivalent in fiat (EUR)
Live Gwei Gas cost estimation
Recipient address validation
Automatic chain change detection
