zkDID API Reference

Special Note: The initial MVP implementation of Findora’s zkDID currently excludes features expected in the final zkDID design such as i) non-transferable NFT support (to store the DIDs on-chain) and ii) IPFS integration to store credentials (and/or proofs) on-chain.

The zkDID API source code is available on [Github](https://github.com/FindoraNetwork/zkdid-js.). To see examples of how to use these APIs visit our zkDID example code document. Below are the zkDID APIs (API descriptions are written in the comments of codebase):
