Project Title:
Kairocoin Presale Platform - EVM Smart Contracts & Frontend DApp
About this project:
Kairocoin is a sophisticated presale website built to facilitate the initial distribution of a new cryptocurrency token on an EVM-compatible blockchain. The primary objective was to create a secure, transparent, and user-friendly platform where participants could connect their crypto wallets and interact directly with the presale smart contract to purchase tokens. This project demanded rigorous attention to smart contract security, precise blockchain interaction, and a highly intuitive frontend experience.
My Responsibilities:
My key contributions to the Kairocoin Presale Platform spanned critical areas of both blockchain smart contract development and user-facing DApp integration, ensuring a robust and secure presale experience:
EVM Smart Contract Development & Auditing:
As part of the core smart contract team, I contributed to the design, development, and optimization of the presale smart contract in Solidity (EVM-compatible).
Participated in extensive testing of the smart contract logic using Foundry, ensuring robustness, security, and adherence to tokenomics before deployment to the mainnet.
Focused on implementing secure token sale mechanisms, token distribution logic, and preventing common vulnerabilities.
Frontend DApp Development (Next.js):
Built the interactive and responsive presale website using Next.js, focusing on a clean and intuitive user interface tailored for cryptocurrency users.
Implemented seamless wallet connectivity and interaction using WalletConnect, Viem, and Wagmi libraries, allowing users to securely connect their wallets, view their balances, and interact with the deployed smart contract.
Developed the logic for real-time display of presale progress, user token allocations, and transaction status updates.
Blockchain Interaction & Data Fetching:
Engineered the frontend to directly communicate with the EVM blockchain, fetching real-time data from the deployed smart contract and sending transaction requests.
Ensured efficient and reliable handling of asynchronous blockchain operations.
User Experience & Security Focus:
Prioritized a secure and transparent user experience, with clear transaction prompts and feedback mechanisms for users interacting with the blockchain.
Collaborated with the team to ensure frontend security best practices were applied to protect user assets and data.
Code Quality & Scalability:
Maintained a high standard of code quality and organization, ensuring the codebase was scalable and easy to extend for future phases of the project.
