What problem does it solve?

Ethereum hashing in Node.js often uses crypto.createHash('sha3-256'), which yields a Keccak variant incompatible with Ethereum tooling. This leads to silent mismatches when computing function selectors, event topics, and signatures.

Core Features & Use Cases

  • Keccak-256 hashing for Ethereum contexts within Node.js/TypeScript projects.
  • Compatible with popular libraries such as ethers, viem, and web3 for consistent hashes.
  • Use cases include building selectors, signing helpers, Merkle proofs, and other Ethereum data processing tasks.

Quick Start

Install and use this skill to hash Ethereum-related data with Keccak-256 in Node.js/TypeScript, ensuring compatibility with Ethereum tooling.
