Project Mandala
NFT Smart Contract & Merkle-Based Allowlist System
Project Mandala is a smart contract infrastructure project built with Solidity and Hardhat. It features an ERC-721A implementation for gas-efficient batch minting, a Merkle tree-based allowlist system using merkletreejs and keccak256 for on-chain verification, and OpenZeppelin's battle-tested contract libraries. The contract supports multi-phase minting with configurable supply and pricing per phase.

Core Contribution
Architected the entire smart contract infrastructure including the ERC-721A implementation for gas-efficient batch minting. Designed and implemented the Merkle tree-based allowlist system using merkletreejs and keccak256, reducing gas costs by ~60% compared to on-chain storage. Built comprehensive Hardhat test suites with Waffle and Chai for contract verification.
Project Overview
A premium NFT collection smart contract featuring a multi-phase launch strategy (OG, Whitelist, Public) with dynamic pricing and supply management. The smart contract was audited and deployed on Ethereum mainnet, utilizing ERC-721A for optimized gas consumption during batch mints.
