Project Plan - Support NFT standards in Weaver for cross-network asset operations

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.
