The ZKsync ecosystem has introduced the 'Atlas' upgrade, aimed at resolving liquidity fragmentation for new ZK Chains. The update allows these chains to interact natively with Ethereum DeFi protocols, effectively removing the 'cold start' liquidity hurdle that typically hinders new network launches. This interoperability feature is designed to allow enterprises and projects building on ZK infrastructure (Prividiums) to immediately tap into the deep liquidity of the Ethereum mainnet.
