HashKey Chain¶
Overview¶
HashKey Chain is a compliance-focused Layer 2 blockchain launched by HashKey Group, designed to provide secure, compliant Web3 infrastructure for institutional and enterprise users. As the technical extension of HashKey Exchange — the first virtual asset trading platform licensed by the Hong Kong Securities and Futures Commission (SFC) — HashKey Chain combines compliance, security, and performance to build a bridge for traditional financial institutions entering Web3.
HashKey Group is a leading digital asset financial services group in Asia, backed by multiple rounds of top-tier institutional investment. HashKey Chain is built on Ethereum Layer 2 technology using a zkRollup solution, providing higher transaction throughput and lower costs while maintaining Ethereum's security, with built-in compliance frameworks and identity verification mechanisms.
HashKey Chain's goal is to become a bridge connecting traditional finance and DeFi, providing infrastructure support for asset tokenization (RWA), institutional DeFi, compliant stablecoins, and other use cases.
