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 | * | * |
To resolve a DID Document, just call the following HTTP GET call:
curl https://resolver.lacchain.net/:didWhere :did represents the DID identifier, for example: did:lac:main:0x5c3968542ca976bec977270d3fe980dd4742865e or did:ethr:0x53671bc6cb20882e45154a9d370d40e19d05125a
It is also possible to deploy this resolver in any server using NodeJS.
