Issue an Asset on Stellar: Set Trustlines, Manage Supply & Distribution

In this tutorial, we will walk through the steps to issue an asset on the Stellar test network.

If you’d like to interact with an asset issued on the Stellar network in smart contracts, you can create or deploy the Stellar Asset Contract for that asset.

Prerequisites

You must ensure you have the required amount of XLM to create your issuing and distribution accounts and cover the minimum balance and transaction fees. If you’re issuing an asset on the testnet, you can fund your account by getting test XLM from friendbot. If you’re issuing an asset in production, you will need to acquire XLM from another wallet or exchange. If you’d like to avoid your users having to deal with transaction fees, consider using fee-bump transactions. Read more in our Fee-Bump Transaction Guide. Learn about the testnet and mainnet in our Networks section. Learn more about fees in our Fees, Resource Limits, and Metering section.

Foundational tools

Issuer account keypair

First, you must generate a unique keypair. The public key will act as your issuing identity on the network, while you use the secret key to sign transactions.

const issuerKeypair = StellarSdk.Keypair.random();

console.log("Issuer Public Key:", issuerKeypair.publicKey());
console.log("Issuer Secret Key:", issuerKeypair.secret());

from stellar_sdk import Keypair

issuer_keypair = Keypair.random()

print("Issuer Public Key:", issuer_keypair.public_key)
print("Issuer Secret Key:", issuer_keypair.secret)

KeyPair issuerKeypair = KeyPair.random();

System.out.println("Issuer Public Key: " + issuerKeypair.getAccountId());
System.out.println("Issuer Secret Key: " + issuerKeypair.getSecretSeed());

import (
  "github.com/stellar/go-stellar-sdk/keypair"
  "fmt"
)

issuerKeypair := keypair.MustRandom()

fmt.Println("Issuer Public Key:", issuerKeypair.Address())
fmt.Println("Issuer Secret Key:", issuerKeypair.Seed())

Your account address will not change once you issue your asset, even if you modify its signers. Many issuers employ vanity public keys related to their asset. For instance, you might configure a custom signer in base32 like GASTRO...USD.

Many users secure their issuing account with cold storage techniques, such as a hardware wallet or multisignature setup. This adds an extra layer of protection by keeping your secret key offline or requiring multiple approvals for transactions.

Distribution account keypair

Your asset can be issued and transferred between accounts through a payment, contract, or claimable balance. Although it is not required to create a distribution account, it is best practice, so we will do so in this example. Read more in our Issuing and Distribution Accounts section.

Three Operations

Generate a new keypair

const distributorKeypair = StellarSdk.Keypair.random();

distributor_keypair = Keypair.random()

KeyPair distributorKeypair = KeyPair.random();

distributorKeypair := keypair.MustRandom()

Import an existing keypair

const distributorKeypair = StellarSdk.Keypair.fromSecret(‘SCZANGBA5YHTNYVVV4C3U252E2B6P6F5T3U6MM63WBSBZATAQI3EBTQ4’)

distributor_keypair = Keypair.from_secret("SCZANGBA5YHTNYVVV4C3U252E2B6P6F5T3U6MM63WBSBZATAQI3EBTQ4")

KeyPair distributorKeypair = KeyPair.fromSecretSeed("SCZANGBA5YHTNYVVV4C3U252E2B6P6F5T3U6MM63WBSBZATAQI3EBTQ4");

distributorKeypair := keypair.MustParseFull("SCZANGBA5YHTNYVVV4C3U252E2B6P6F5T3U6MM63WBSBZATAQI3EBTQ4")

Employ multiple signatures

Be careful when working with raw secret keys. If you don’t have issuer trustline clawback enabled, any misstep here could permanently render assets lost. Many users put their first few projects on testnet or try out Quests which provide a low-stakes introductory sandbox.

Local asset object

The asset object is a combination of your code and your issuing public key. After your issuance, anyone can search the network for your unique asset.

const astroDollar = new StellarSdk.Asset(
  "AstroDollar",
  issuerKeypair.publicKey(),
);

from stellar_sdk import Keypair, Asset

astro_dollar = Asset("AstroDollar", issuer_keypair.public_key)

Asset astroDollar = Asset.createNonNativeAsset("AstroDollar", issuerKeypair.getAccountId());

import (
  "github.com/stellar/go-stellar-sdk/keypair"
  "github.com/stellar/go-stellar-sdk/txnbuild"
)

astroDollar := txnbuild.CreditAsset{Code: "AstroDollar", Issuer: issuerKeypair.Address()}

While anyone can create an asset, there may be real-world compliance implications relevant to your use case.

You’ll want to make sure you publish information about your asset to establish trust with your users and prevent errors. Learn how to do so with our Publish Information About Your Asset section.

Network transactions

These examples read accounts from and submit transactions to Stellar RPC. RPC takes a transaction and answers immediately with the status PENDING, so you then poll for the final result. See sendTransaction and getTransaction.

Build transaction to establish distributor trustline

Accounts must establish a trustline with the issuing account to hold that issuer’s asset. This is true for all assets except for the network’s native token, Lumens.

If you’d like to avoid your users having to deal with trustlines or XLM, consider using sponsored reserves. Read more in our Sponsored Reserves guide.

const StellarSdk = require("@stellar/stellar-sdk");
const server = new StellarSdk.rpc.Server("https://soroban-testnet.stellar.org");
const account = await server.getAccount(distributorKeypair.publicKey());

// This step only builds the transaction.  It still needs to be signed.
const transaction = new StellarSdk.TransactionBuilder(account, {
  fee: StellarSdk.BASE_FEE,
  networkPassphrase: StellarSdk.Networks.TESTNET,
})
  // The `changeTrust` operation creates (or alters) a trustline
  .addOperation(
    StellarSdk.Operation.changeTrust({
      asset: astroDollar,
      limit: "1000", // optional
      source: distributorKeypair.publicKey(),
    }),
  )
  .setTimeout(100)
  .build();

from stellar_sdk import Keypair, Asset, Network, SorobanServer, TransactionBuilder

server = SorobanServer("https://soroban-testnet.stellar.org")
distributor_account = server.load_account(distributor_keypair.public_key)

transaction = (
  TransactionBuilder(
    source_account=distributor_account,
    network_passphrase=Network.TESTNET_NETWORK_PASSPHRASE,
    base_fee=100
  )
  .append_change_trust_op(asset=astro_dollar, limit="1000")
  .set_timeout(100)
  .build()
)

SorobanServer server = new SorobanServer("https://soroban-testnet.stellar.org");
TransactionBuilderAccount distributorAccount = server.getAccount(distributorKeypair.getAccountId());

Transaction transaction = new TransactionBuilder(distributorAccount, Network.TESTNET)
  .addOperation(

    .asset(new ChangeTrustAsset(astroDollar))
    .limit(new BigDecimal("1000"))
    .sourceAccount(distributorKeypair.getAccountId())
    .build()
  )
  .setBaseFee(Transaction.MIN_BASE_FEE)
  .setTimeout(100)
  .build();

import (
  "context"

  "github.com/stellar/go-stellar-sdk/clients/rpcclient"
  "github.com/stellar/go-stellar-sdk/keypair"

)

ctx := context.Background()
client := rpcclient.NewClient("https://soroban-testnet.stellar.org", nil)
distributorAccount, _ := client.LoadAccount(ctx, distributorKeypair.Address())

transaction, _ := txnbuild.NewTransaction(
  txnbuild.TransactionParams{
    SourceAccount:        distributorAccount,
    IncrementSequenceNum: true,
    BaseFee:              txnbuild.MinBaseFee,
    Operations: []txnbuild.Operation{
      &txnbuild.ChangeTrust{
        Line:  astroDollar.MustToChangeTrustAsset(),
        Limit: "1000",
      },
    },
    Timebounds: txnbuild.NewInfiniteTimeout(),
  },
)

Issuer payment to distributor

Payments are the most popular operation to actually issue (or mint) your asset, compared to other issuances. A payment creates the amount of an asset specified, up to the maximum 64-bit integer. Relevantly, you do not need to scale up the issuing amount of your asset by the XDR minimum increment.

// We're using TransactionBuilder(...) as a short-hand here
// to show that these operations can be "chained" together.
const transaction = new StellarSdk.TransactionBuilder(...)
  // The `payment` operation sends the `amount` of the specified
  // `asset` to our distributor account
  .addOperation(StellarSdk.Operation.payment({
    destination: distributorKeypair.publicKey(),
    asset: astroDollar,
    amount: '1000',
    source: issuerKeypair.publicKey()
  }))

# We're using TransactionBuilder(...) as a short-hand here
# to show that these operations can be "chained" together.
transaction = (
  TransactionBuilder(...)
  .append_payment_op(
    destination=distributor_keypair.public_key,
    asset=astro_dollar,
    amount="1000"
  )
)

// We're using TransactionBuilder(...) as a short-hand here
// to show that these operations can be "chained" together.
Transaction transaction = new TransactionBuilder(...)
  .addOperation(PaymentOperation.builder()
    .destination(distributorKeypair.getAccountId())
    .asset(astroDollar)
    .amount(new BigDecimal("1000"))
    .sourceAccount(issuerKeypair.getAccountId())
    .build())

// We're using TransactionBuilder(...) as a short-hand here
// to show that these operations can be "chained" together.
transaction, _ := txnbuild.NewTransaction(
  txnbuild.TransactionParams{
    SourceAccount:        issuerAccount,
    IncrementSequenceNum: true,
    BaseFee:              txnbuild.MinBaseFee,
    Operations: []txnbuild.Operation{
      &txnbuild.Payment{
        Destination: distributorKeypair.Address(),
        Amount:      "1000",
        Asset:       astroDollar,
      },
    },
    Timebounds: txnbuild.NewInfiniteTimeout(),
  },
)

You can also create a market directly from the issuing account and issue tokens via trading.

Optional transactions

Configure maximum supply

This section details how to lock your account with the purpose of limiting the supply of your issued asset. However, locking your account means you’ll never be able to do anything with it ever again—whether that’s adjusting signers, changing the home domain, claiming any held XLM, or any other operation. Your account will be completely frozen.

You can permanently configure the exact number of an asset that will ever exist. Learn more about asset supply in our section on Limiting the Supply of an Asset

const lockAccountTransaction = new StellarSdk.TransactionBuilder(...)
  // This `setOptions` operation locks the issuer account
  // so there can never be any more of the asset minted
  .addOperation(StellarSdk.Operation.setOptions({
    masterWeight: 0,
    source: issuerKeypair.publicKey()
  }))

lock_account_transaction = (
  TransactionBuilder(...)
  .append_set_options_op(master_weight=0)
)

Transaction lockAccountTransaction = new TransactionBuilder(...)
  .addOperation(SetOptionsOperation.builder()
    .masterKeyWeight(0)
    .sourceAccount(issuerKeypair.getAccountId())
    .build()
  )

lockAccountTransaction, _ := txnbuild.NewTransaction(
  txnbuild.TransactionParams{
    SourceAccount:        issuerAccount,
    IncrementSequenceNum: true,
    BaseFee:              txnbuild.MinBaseFee,
    Operations: []txnbuild.Operation{
      &txnbuild.SetOptions{
        MasterWeight: txnbuild.NewThreshold(0),
      },
    },
    Timebounds: txnbuild.NewInfiniteTimeout(),
  },
)

Approve distributor trustline

If you enable the authorization flag, the issuing account also needs to approve the distributor account’s trustline request before the issuing payment. You will need to do this for all new accounts when set for your asset.

const issuingAccount = await server.getAccount(issuerKeypair.publicKey());
const transaction = new StellarSdk.TransactionBuilder(...)
  .addOperation(
    StellarSdk.Operation.setTrustLineFlags({
      trustor: distributorKeypair.publicKey(),
      asset: astroDollar,
      flags: {
        authorized: true,
      },
    }),
  )
  .setTimeout(100)
  .build();

from stellar_sdk import SorobanServer, Keypair, Network, TransactionBuilder, SetTrustLineFlags

server = SorobanServer("https://soroban-testnet.stellar.org")
issuer_account = server.load_account(issuer_keypair.public_key)

transaction = (
    TransactionBuilder(...)
    .append_set_trust_line_flags_op(
        trustor=distributor_keypair.public_key,
        asset=astro_dollar,
        flags=SetTrustLineFlags.AUTHORIZED_FLAG
    )
    .set_timeout(100)
    .build()
)

TransactionBuilderAccount issuerAccount = server.getAccount(issuerKeys.getAccountId());
Transaction transaction = new TransactionBuilder(...)
  .addOperation(SetTrustlineFlagsOperation.builder()
    .trustor(distributorKeys.getAccountId())
    .asset(astroDollar)
    .setFlags(EnumSet.of(TrustLineFlags.AUTHORIZED_FLAG))
    .clearFlags(EnumSet.noneOf(TrustLineFlags.class))
    .build())
  .setBaseFee(Transaction.MIN_BASE_FEE)
  .setTimeout(100)
  .build();

issuerAccount, _ := client.LoadAccount(ctx, issuerKeypair.Address())

transaction, _ := txnbuild.NewTransaction(
  txnbuild.TransactionParams{
    SourceAccount:        issuerAccount,
    IncrementSequenceNum: true,
    BaseFee:              txnbuild.MinBaseFee,
    Operations: []txnbuild.Operation{
      &txnbuild.SetTrustLineFlags{
        Trustor:   distributorKeypair.Address(),
        Asset:     astroDollar,
        Authorized: txnbuild.AuthorizeFlag,
      },
    },
    Timebounds: txnbuild.NewInfiniteTimeout(),
  },
)
