EXRNchain is a protocol and network for crosschain value and data transfer between distributed ledgers (blockchains).EXRNchain protocol allows better, faster, simpler atomic swaps between different cryptocurrencies. We will implement it in our EXRNswaps service.EXRNchain protocol can be used to transfer any encrypted data between distributed ledgers (which brings many use cases in connection with IPFS technology).EXRNchain protocol allows call or execution of specific smart contract function of one blockchain to be sent from another chain. Connect to and operate your Ethereum, Qtum, Neo and etc. contracts from one place.
