Transactions — HCS‑5

Note

• These flows are typically orchestrated via higher‑level SDK helpers.
• Direct transaction construction is common only when integrating with custom minting pipelines.

Mint Hashinal — HTS TokenMint

HCS‑5 uses HTS mint and sets serial metadata to an HCS‑1 HRL.

TypeScript

import { TokenMintTransaction, TokenId } from '@hashgraph/sdk';
import { buildHcs1Hrl } from '@hashgraphonline/standards-sdk';

const metadata = buildHcs1Hrl('0.0.700001');
const tx = new TokenMintTransaction()
  .setTokenId(TokenId.fromString('0.0.123456'))
  .setMetadata([Buffer.from(metadata)]);
await (await tx.execute(client)).getReceipt(client);

Go

import "github.com/hashgraph-online/standards-sdk-go/pkg/hcs5"

// BuildHCS1HRL returns "hcs://1/<topicId>"
hrl := hcs5.BuildHCS1HRL("0.0.700001")

// BuildMintWithHRLTx builds a TokenMintTransaction with the HRL as metadata
tx, err := hcs5.BuildMintWithHRLTx("0.0.123456", "0.0.700001", "mint hashinal")
if err != nil {
	log.Fatal(err)
}

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

Helper — BuildHCS1HRL

TypeScript

import { buildHcs1Hrl } from '@hashgraphonline/standards-sdk';

const hrl = buildHcs1Hrl('0.0.700001');
// => "hcs://1/0.0.700001"

Go

hrl := hcs5.BuildHCS1HRL("0.0.700001")
// => "hcs://1/0.0.700001"
