## Description:

Pigeon DAO connects independent package couriers with customers and allows them to communicate and get paid in crypto through decentralised networks to deliver packages.

Tech Stack:

*   HTML5

*   CSS3

*   TailwindCSS

*   JavaScript

*   Typescript

*   Next.js

*   Solidity

*   Ethers.js

*   Hardhat

## Tools:

*

*

*

*   Jira

*   Slack

*   Visual Studio Code

*   Webpack

*   OpenZeppelin

## Problem

Pigeon DAO is a decentralised courier protocol. We were trying to a protocol for couriers to connect with customers directly through decentralised protocols, but in a way that was both secure AND scalable.

## Solution

So for this we needed to figure out what tools and skills we needed, so that we could learn and use them. We figured out what decentralised protocols we needed, which was Ethereum, XYO Network and Waku protocol, a libp2p-based protocol. We looked into the technologies within them we needed to learn and started learning and implementing them. We are close to launching our V1 of Pigeon, which will be followed by the DAO to fund and manage the protocol.

## Future Steps

Further optimization of page load speeds and reducing bundle sizes of resources. Refactoring of custom CSS and JavaScript can be done to achieve a lower time to first byte and first paint.

Additional automated testing scripts can be written to test common functions of the website. This reduces the need for user testing and frees up developer time for more productive tasks.

Expansion of horizontal scaling was in the works for ROCCAT Gaming. The 13 Shopify Plus stores initially configured for launch eventually expanded to 20+ stores to scale horizontally across additional regions.

# Results

*   A successful launch of an international DTC e-commerce brand across 13+ Shopify Plus stores.

*   Generated millions of dollars in revenue for ROCCAT Gaming and their stakeholders.

## Project Overview

The goal of this project is to create an NFT marketplace where users can buy, sell, and trade non-fungible tokens (NFTs) on the Ethereum blockchain. The marketplace will be built using Solidity for smart contract development, ethers.js for interacting with the Ethereum blockchain, and React for front-end development.

## Features

1.  User Authentication: Users should be able to sign up and log in to the platform using their Ethereum wallet address and private key.

2.  NFT Marketplace: Users can browse and purchase NFTs listed for sale by other users. They can also list their own NFTs for sale, set their own prices, and receive payments in Ether.

3.  NFT Trading: Users can trade NFTs with other users. They can create their own trades and set their own terms, including the NFT(s) they are willing to trade and the NFT(s) they want in return.

4.  Auctions: Users can create auctions for their NFTs, allowing other users to bid on them. The highest bidder at the end of the auction will win the NFT.

5.  NFT History: Users can view the transaction history of any NFT, including its previous owners and the price it was sold for.

6.  Wallet Integration: Users can connect their Ethereum wallet to the platform to view their NFTs and Ether balance.

7.  Search: Users can search for specific NFTs based on keywords or attributes.

8.  Notifications: Users will receive notifications when they have sold an NFT, when a trade has been accepted, or when an auction they are bidding on is ending soon.

## Tech Stack

1.  Smart Contract Development: Solidity, Remix IDE, Truffle

2.  Blockchain Interaction: ethers.js, Web3.js

3.  Front-end Development: React, Material UI

4.  Testing: Mocha, Chai

## Deliverables

1.  Solidity smart contracts that handle the core functionality of the NFT marketplace, including buying and selling NFTs, creating and accepting trades, and creating and participating in auctions.

2.  A React-based front-end that allows users to interact with the smart contracts and use the features of the platform.

3.  Unit and integration tests for the smart contracts and front-end components.

4.  A deployment script to deploy the smart contracts and front-end to the Ethereum blockchain.

## Timeline

1.  Week 1-2: Develop the smart contracts using Solidity, Remix IDE, and Truffle. Write and execute unit tests.

2.  Week 3-4: Develop the React-based front-end using Material UI. Integrate the front-end with the smart contracts using ethers.js.

3.  Week 5-6: Write and execute integration tests for the smart contracts and front-end components.

4.  Week 7-8: Deploy the smart contracts and front-end to the Ethereum blockchain. Conduct a thorough end-to-end testing of the platform.

## Conclusion

The NFT marketplace project is a challenging and exciting opportunity to build a platform that leverages the power of the Ethereum blockchain to enable users to buy, sell, and trade NFTs. By using Solidity for smart contract development, ethers.js for interacting with the Ethereum blockchain, and React for front-end development, you can create a robust and user-friendly marketplace that is easy to use and navigate. With thorough testing and deployment, you can ensure that your NFT marketplace is secure, reliable, and scalable.

## Project Description

The project is a decentralized exchange built on Ethereum using Solidity for smart contract development and web3.js for interaction with an RPC node to get on-chain data from. The decentralized exchange allows users to trade Ethereum-based tokens in a peer-to-peer manner without relying on a central authority or intermediary.

## Features

1.  **Token listing and trading** - The decentralized exchange allows users to list their Ethereum-based tokens and trade them with other users on the platform. The exchange should support both limit and market orders.

2.  **Order book** - The order book displays the current buy and sell orders for each token. Users should be able to view the order book for each token pair.

3.  **Trading history** - The trading history shows all the past trades for each token pair.

4.  **Liquidity pools** - The exchange uses liquidity pools to ensure that there is always enough liquidity for users to trade. The liquidity pools are created by users who provide liquidity in exchange for a portion of the trading fees.

5.  **Trading fees** - The exchange charges a fee on each trade, which is split between the liquidity providers and the exchange operator.

6.  **User wallets** - Users can connect their Ethereum wallets to the decentralized exchange to deposit and withdraw tokens. Users should also be able to view their token balances and transaction history.

7.  **Gas optimization** - The smart contracts should be optimized for gas usage to minimize transaction costs for users.

8.  **Security** - The decentralized exchange should be secure and audited to prevent hacks and exploits.

## Technology Stack

*   Solidity for smart contract development

*   web3.js for interaction with an RPC node

*   Ethereum for blockchain platform

*   Truffle for smart contract development and testing

*   React for front-end development

*   Redux for state management

## Architecture

The decentralized exchange consists of the following components:

*   Smart contracts for token listing, trading, and liquidity pools

*   Web3.js API for interacting with the Ethereum blockchain

*   Front-end interface for users to interact with the exchange

*   Ethereum wallet integration for users to deposit and withdraw tokens

*   Order book and trading history for each token pair

*   Liquidity pool management for users to provide and withdraw liquidity

## Milestones

1.  **Project setup** - Set up the project with Truffle, Solidity, web3.js, and React.

2.  **Token listing and trading** - Implement the smart contracts for token listing and trading. Users should be able to create and cancel limit orders and execute market orders.

3.  **Order book and trading history** - Implement the order book and trading history for each token pair.

4.  **Liquidity pools** - Implement the smart contracts for liquidity pools and allow users to provide and withdraw liquidity.

5.  **Trading fees** - Implement the trading fee mechanism and distribute fees to liquidity providers and the exchange operator.

6.  **User wallets** - Implement Ethereum wallet integration for users to deposit and withdraw tokens. Users should also be able to view their token balances and transaction history.

7.  **Gas optimization** - Optimize the smart contracts for gas usage to minimize transaction costs for users.

8.  **Security** - Perform a security audit and implement necessary measures to prevent hacks and exploits.

9.  **Testing and deployment** - Test the decentralized exchange thoroughly and deploy it to the Ethereum mainnet.
