The Cronos chain is an Ethereum Virtual Machine (EVM) compatible blockchain which runs in parallel to the Crypto.org chain. Moreover, it is compatible with the Inter Blockchain Communication (IBC) protocol, where you are able to interact with the Cosmos ecosystem.
Similar to other networks (like Ethereum or Binance Smart Chain), you are able to interact with decentralised apps (dApps) that range from DeFi protocols, NFTs and Bridges.
You can swap tokens via SmartSwap. Some platforms that SmartSwap will be sourcing liquidity from 8 DEXes, including:
You will need to use CRO (Cronos) to process transactions, which is similar to how you would use ETH to process transactions on the ERC20 network.
As such, don’t forget to leave enough CRO in your non-custodial wallet to be able to process your transactions!
