Transactions — HCS‑6

Note

• These builders are for direct transaction construction (e.g., with the Standards Agent Kit or custom pipelines).
• For most applications, prefer the higher‑level sdk.ts (Node) or browser.ts (wallet) clients.

HCS‑6 uses a non‑indexed registry memo (hcs-6:1:<ttl>) and defines two builders for creating the registry and registering entries.

Create Registry — buildHcs6CreateRegistryTx

Signature

buildHcs6CreateRegistryTx(params: {
  ttl: number;
  submitKey?: boolean | string | Key; // MaybeKey
  adminKey?: boolean | string | Key;  // MaybeKey
  memoOverride?: string;
  operatorPublicKey?: PublicKey;
}): TopicCreateTransaction

Example

import { buildHcs6CreateRegistryTx } from '@hashgraphonline/standards-sdk';

const tx = buildHcs6CreateRegistryTx({ ttl: 3600, adminKey: true, submitKey: true });
// Node
const receipt = await (await tx.execute(client)).getReceipt(client);

Notes

• Defaults memo to hcs-6:1:<ttl> unless memoOverride is provided.
• adminKey/submitKey accept boolean (use operator), raw string, or Key.

Register Entry — buildHcs6RegisterEntryTx

Signature

buildHcs6RegisterEntryTx(params: {
  registryTopicId: string;
  targetTopicId: string;
  memo?: string;          // payload memo field
  analyticsMemo?: string; // Hedera tx memo
}): TopicMessageSubmitTransaction

Example

import { buildHcs6RegisterEntryTx } from '@hashgraphonline/standards-sdk';

const tx = buildHcs6RegisterEntryTx({
  registryTopicId: '0.0.111',
  targetTopicId: '0.0.222',
  memo: 'register my dynamic inscription',
  analyticsMemo: 'hcs-6 register',
});
// Node
await (await tx.execute(client)).getReceipt(client);

Payload

{ "p": "hcs-6", "op": 0, "t_id": "0.0.222", "m": "register my dynamic inscription" }
