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 client (Node/Go) or browser client (wallet).

Sources

• TypeScript: GitHub
• Go: GitHub

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

TypeScript

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.

Go

import "github.com/hashgraph-online/standards-sdk-go/pkg/hcs6"

tx := hcs6.BuildCreateRegistryTx(hcs6.CreateRegistryTxParams{
	TTL:       3600,
	AdminKey:  operatorPublicKey, // hedera.Key
	SubmitKey: operatorPublicKey,
})

response, err := tx.Execute(hederaClient)
receipt, err := response.GetReceipt(hederaClient)

Notes

• Memo is automatically set to hcs-6:1:<ttl>.
• Pass AdminKey/SubmitKey as hedera.Key values.

Python

tx = hcs6.build_create_registry_tx(ttl=3600, admin_key=operatorPublicKey,

Register Entry — buildHcs6RegisterEntryTx

TypeScript

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);

Go

tx, err := hcs6.BuildRegisterEntryTx(hcs6.RegisterEntryTxParams{
	RegistryTopicID: "0.0.111",
	TargetTopicID:   "0.0.222",
	Memo:            "register my dynamic inscription",
	AnalyticsMemo:   "hcs-6 register",
})
if err != nil {
	log.Fatal(err)
}

response, err := tx.Execute(hederaClient)
receipt, err := response.GetReceipt(hederaClient)

Python

tx = hcs6.build_register_entry_tx(registry_topic_id="0.0.111", target_topic_id="0.0.222", memo="register my dynamic inscription", analytics_memo="hcs-6 register")

response = tx.execute(hederaClient)
receipt = response.get_receipt(hederaClient)

Payload

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