Abstract
The scope of this project covers interoperation support for these three prominent ERC token types across Hyperledger Fabric, Corda and Hyperledger Besu networks. Weaver currently supports interoperation between ERC-20 token types for Hyperledger Besu networks. Weaver The goal of this project is to add support for ERC-721 and ERC-1155 standards for interoperation among Hyperledger Besu networks, and extend support for ERC-20, ERC-721 and ERC-1155 token types to interoperate across all three DLT platforms supported by Weaver i.e., Hyperledger Fabric, Corda and Hyperledger Besu, to the extent possible in the duration of the internship.
