Cardano development company Input Output Global (IOG) has launched a custom EVM-compatible sidechain toolkit. The proof-of-concept version has been launched on the testnet on February 7. The toolkit consists of three core components, including Mainchain Plutus scripts (supporting secure cross-chain transactions and token movement), on-chain trackers (track main chain data and events that manage side chains), side chain modules (interpret main chain data and implement necessary ledger adjustments), developers can build for Cardano Customize sidechains to support more on-chain functions and scalability.
