Overview

HashKey Chain is a next-generation Ethereum Layer-2 solution designed to deliver scalability, interoperability, and cost-efficiency. Built on the OP Stack and integrated into the Optimism Superchain, it leverages Ethereum’s security with Rollup technology to ensure fast, low-cost transactions.

Fully EVM-compatible, HashKey Chain simplifies the migration of existing Ethereum-based dApps and smart contracts, offering a seamless experience for developers. It also supports cutting-edge use cases, including BTCFi, stablecoins, real-world asset tokenization (RWA), and PayFi, creating a bridge between blockchain innovation and traditional financial systems.
