Ion is a platform agnostic interoperability framework. It allows state and value to be transferred between disparate blockchains without the need for an intermediary token or a trusted intermediary.

The Ion project currently has validation contracts for

  • Clique (Ethereum)

  • IBFT (Ethereum)

  • Hyperledger Fabric

The Ion Github repository has a full example of transfering value between a local test chain and Rinkeby. The Simple Shares example shows a simplified conceptual DvP flow, modelling the issuance of a security on Fabric and the settlement of the cash leg of a trade on an Ethereum chain.
