DID Resolver for multiple DID methods

The Universal Resolver resolves Decentralized Identifiers (DIDs) across many different DID methods, it uses HTTP GET requests to get DID Document from each DID method.

This project also includes the LACChain DID method to resolve did:lac identifiers.

Currently, these are the following supported DID methods:

Method	Network	Subnetwork
lac	LACChain	MainNet
ethr	LACChain	MainNet
ethr	Ethereum	*
lac1	LACChain	MainNet
web	*	*
btcr	*	*
sov	*	*
elem	*	*
nacl	*	*
elsi	*	*

Usage

To resolve a DID Document, just call the following HTTP GET call:

curl https://resolver.lacchain.net/:did

Where :did represents the DID identifier, for example: did:lac:main:0x5c3968542ca976bec977270d3fe980dd4742865e or did:ethr:0x53671bc6cb20882e45154a9d370d40e19d05125a
