Kraken, the US-based crypto exchange, has disclosed the impending mainnet launch date for Ink, its in-house Layer 2 (L2) network. Announced initially in October, the L2 is based on the Optimism (OP) superchain and uses Ethereum's (ETH) standard codebase. Ink will reportedly facilitate a multitude of functions, including on-ramps and on-chain services, and connect users to decentralized finance (DeFi) protocols. ---
