Transactions — HCS‑20 Builders

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).

Deploy

TypeScript

import { buildHcs20DeployTx } from '@hashgraphonline/standards-sdk';

const tx = buildHcs20DeployTx({
  topicId: '0.0.100',
  name: 'Loyalty Points',
  tick: 'loyal',
  max: '1000000000',
  lim: '10000',
  metadata: 'ipfs://…',
  memo: 'deploy',
});

Go

import "github.com/hashgraph-online/standards-sdk-go/pkg/hcs20"

tx, err := hcs20.BuildHCS20DeployTx(hcs20.DeployTxParams{
	TopicID:  "0.0.100",
	Name:     "Loyalty Points",
	Tick:     "loyal",
	Max:      "1000000000",
	Lim:      "10000",
	Metadata: "ipfs://…",
	Memo:     "deploy",
})
if err != nil {
	log.Fatal(err)
}

Mint

TypeScript

import { buildHcs20MintTx } from '@hashgraphonline/standards-sdk';

const tx = buildHcs20MintTx({
  topicId: '0.0.100',
  tick: 'loyal',
  amt: '100',
  to: '0.0.12345',
  memo: 'reward',
});

Go

	To:      "0.0.12345",
	Memo:    "reward",
})

Transfer

TypeScript

import { buildHcs20TransferTx } from '@hashgraphonline/standards-sdk';

const tx = buildHcs20TransferTx({
  topicId: '0.0.100',
  tick: 'loyal',
  amt: '10',
  from: '0.0.111',
  to: '0.0.222',
  memo: 'tip',
});

Go

tx, err := hcs20.BuildHCS20TransferTx(hcs20.TransferTxParams{
	TopicID: "0.0.100",
	Tick:    "loyal",
	Amt:     "10",
	From:    "0.0.111",
	To:      "0.0.222",
	Memo:    "tip",
})

Burn

TypeScript

import { buildHcs20BurnTx } from '@hashgraphonline/standards-sdk';

const tx = buildHcs20BurnTx({
  topicId: '0.0.100',
  tick: 'loyal',
  amt: '5',
  from: '0.0.111',
  memo: 'cleanup',
});

Go

tx, err := hcs20.BuildHCS20BurnTx(hcs20.BurnTxParams{
	TopicID: "0.0.100",
	Tick:    "loyal",
	Amt:     "5",
	From:    "0.0.111",
	Memo:    "cleanup",
})

Register (Directory)

TypeScript

import { buildHcs20RegisterTx } from '@hashgraphonline/standards-sdk';

const tx = buildHcs20RegisterTx({
  registryTopicId: '0.0.999',
  name: 'Loyalty Points',
  topicId: '0.0.100',
  isPrivate: false,
  metadata: 'ipfs://…',
  memo: 'register',
});

Go

tx, err := hcs20.BuildHCS20RegisterTx(hcs20.RegisterTxParams{
	RegistryTopicID: "0.0.999",
	Name:            "Loyalty Points",
	TopicID:         "0.0.100",
	IsPrivate:       false,
	Metadata:        "ipfs://…",
	Memo:            "register",
})

Execution

TypeScript

• Node: await tx.execute(client).then(r => r.getReceipt(client))
• Browser: await (await tx.freezeWithSigner(signer)).executeWithSigner(signer) then getReceiptWithSigner

Go

response, err := tx.Execute(hederaClient)
if err != nil {
	log.Fatal(err)
}
receipt, err := response.GetReceipt(hederaClient)
