Cross-chain automated market maker Symbiosis has integrated layer-2 scaling protocol zkSync to improve speed and reduce fees of token swaps on its platform. The integration of zkSync enables one-click swaps from Ethereum, Polygon, Avalanche, BNB, Telos, and other blockchains into zkSync and back, while also supporting any-to-any native swaps. The additional functionality also removes the need for users to switch between different wallets and interfaces. Symbiosis co-founder Nick Avramov believes that ZK rollups could outcompete optimistic rollup solutions and that cross-chain players and interoperability layers must support ZK solutions as soon as possible. Symbiosis has processed over $100 million in total transaction volume in stablecoins, serves over 12,000 unique wallet addresses, and an average of 3,000 daily transactions.
