Hedera (Optional)

Hedera support is optional. Use it when you want to issue did:hedera and resolve Hedera DIDs from UAIDs.

Issue did:hederaDirect link to issue-didhedera​

import { HCS14Client } from '@hashgraphonline/standards-sdk';

const hcs14 = new HCS14Client({
  network: 'testnet',
  operatorId: process.env.HEDERA_ACCOUNT_ID!,
  privateKey: process.env.HEDERA_PRIVATE_KEY!,
});

const did = await hcs14.createDid({ method: 'hedera', client /* configured Hedera Client */ });

Issue and generate UAID togetherDirect link to Issue and generate UAID together​

For HCS‑10 on Hedera, uid derives to inboundTopicId@accountId when available (falls back to accountId). nativeId uses Hedera CAIP‑10.

const { did, uaid, parsed } = await hcs14.createDidWithUaid({
  issue: { method: 'hedera', client },
  proto: 'hcs-10',
});

Resolve DID / UAID ProfilesDirect link to Resolve DID / UAID Profiles​

The Hedera resolver is registered automatically by HCS14Client.

const didProfile = await hcs14.resolveDidProfile('did:hedera:testnet:0.0.1234');
const uaidProfile = await hcs14.resolveUaidProfile('uaid:did:z6Mk...;uid=0;proto=hcs-10;nativeId=hedera:testnet:0.0.1234');
const didDocument = await hcs14.getResolverRegistry().resolveUaid('uaid:did:z6Mk...;uid=0;proto=hcs-10;nativeId=hedera:testnet:0.0.1234');
