API Summary

HCS14Client

Method	Parameters (summary)	Returns	Notes
createUaid(data, params?, opts?)	data: CanonicalAgentData, params: DidRoutingParams, opts: { includeParams?: boolean }	Promise<string>	Generates uaid:aid:.... Canonicalizes 6 fields, hashes (SHA‑384 → Base58). When includeParams === false, omits routing params.
createUaid(did, params?)	did: string, params: DidRoutingParams	string	Generates uaid:did:.... Sanitizes method‑specific id (strips ; ? #). Adds src (multibase b58btc) if sanitization removed a suffix.
parseHcs14Did(value)	value: string	Parsed UAID object (method, id, params)	Parses UAID into method, id, and params.
createDid({ method, ... })	DidIssueRequest	Promise<string>	Issues a DID via registered issuers (e.g., method hedera). Hedera requires a configured Client.
createDidWithUaid({ issue, proto?, uid?, nativeId? })	issue: DidIssueRequest, optional proto, uid, nativeId	Object with did, uaid, parsed	Issues a DID, then generates UAID. For Hedera + proto hcs-10, derives uid (inboundTopicId@accountId when available) and nativeId (Hedera CAIP‑10) when not provided.
getIssuerRegistry() / getResolverRegistry()	—	registries	Access registries to register/list/filter adapters.
listIssuers() / listResolvers()	—	arrays	Introspection of registered adapters (includes meta).
filterIssuersByMethod(method) / filterResolversByMethod(method)	method: string	arrays	Find adapters that support a DID method.

CAIP Helpers

Helper	Signature	Returns	Notes
toHederaCaip10	(network: HederaNetwork, accountId: string)	string	Builds hedera:<network>:<accountId>. Validates input.
parseHederaCaip10	(value: string)	Object with network and accountId	Parses and validates a Hedera CAIP‑10 string.
isHederaNetwork	(value: string)	boolean	Type guard for Hedera networks.
isHederaCaip10	(value: string)	boolean	Validates Hedera CAIP‑10 format.
toEip155Caip10	(chainId: number or string, address: string)	string	Builds eip155:<chainId>:<0xAddress>. Validates input.
isEip155Caip10	(value: string)	boolean	Validates EIP‑155 CAIP‑10 format.

HederaNetwork values: mainnet, testnet, previewnet, devnet.
