Merkle Library

Gas-Optimized Solidity Merkle Proof Verification

The Merkle Library is an infrastructure-level Solidity library built with Foundry that provides gas-optimized Merkle proof verification for on-chain allowlist management. It powers the allowlist systems across all Pixel8Labs NFT projects, enabling efficient whitelist management without storing addresses on-chain. The library uses Foundry's Forge for testing and Soldeer for dependency management.

Core Contribution

Authored the complete Solidity library from scratch using Foundry. Implemented the Merkle tree construction algorithm and on-chain verification functions in Solidity. Optimized gas consumption through assembly-level hashing and memory management. Set up the Foundry development environment with Forge testing, Soldeer dependency management, and CI/CD via GitHub Actions.

Project Overview

A foundational infrastructure library used across all Pixel8Labs NFT projects. It standardizes the allowlist verification pattern, reducing per-project development time and ensuring consistent security across deployments. Built entirely with Foundry's modern Solidity toolchain.
