1Sat Ordinals - JS Library

js-1sat-ord

A Javascript library for creating and managing 1Sat Ordinal inscriptions and transactions. Uses @bsv/sdk under the hood.

Install

Install the library, and it's peer dependency. We recommend using Bun for the best performance, but you can also use Yarn or npm:

# Using Bun (recommended)
bun add js-1sat-ord @bsv/sdk

# Using Yarn
yarn add js-1sat-ord @bsv/sdk

# Using npm
npm i js-1sat-ord @bsv/sdk

Usage

import { createOrdinals, sendOrdinals, sendUtxos, deployBsv21Token, transferOrdToken } from 'js-1sat-ord'

Example

Prepare some utxos to use in the following format. Be sure to use base64 encoded scripts. We use this encoding because it makes large scripts smaller in size.

import type { Utxo } from "js-1sat-ord";

const utxo: Utxo = {
  satoshis: 269114,
  txid: "61fd6e240610a9e9e071c34fc87569ef871760ea1492fe1225d668de4d76407e",
  script: "<base64 encoded script>",
  vout: 1,
};

You can use the helper fetchPayUtxos(address) to fetch unspent transaction outputs from the public 1Sat API and create the scripts with the correct encoding. This should be a BSV address, not your ordinals address.

import { fetchPayUtxos } from "js-1sat-ord";

const utxos = await fetchPayUtxos(payAddress)

Prepare Inscription

For a markdown inscription, you can create a string and convert it to base64:

import type { Inscription } from "js-1sat-ord";


// Create a markdown string
const markdownContent = "# Hello World!\n\nThis is a 1Sat Ordinal inscription.";

// Convert to base64
const encodedFileData = Buffer.from(markdownContent).toString('base64');

// Prepare the inscription object
const inscription: Inscription = {
  dataB64: encodedFileData,
  contentType: "text/markdown"
};

Prepare Keys

Be sure to use different keys for ordinals and normal payments:

import { PrivateKey } from "js-1sat-ord";

const paymentPk = PrivateKey.fromWif(paymentWif);
const ordPk = PrivateKey.fromWif(ordWif);

Create Ordinals

The createOrdinals function creates a transaction with inscription outputs:

import type { CreateOrdinalsConfig } from "js-1sat-ord";

const config: CreateOrdinalsConfig = {
  utxos: [utxo],
  destinations: [{
    address: ordinalDestinationAddress,
    inscription: { dataB64: encodedFileData, contentType: "text/markdown" }
  }],
  paymentPk: paymentPk
};

const result = await createOrdinals(config);

Send Ordinals

Sends ordinals to the given destinations:

import type { SendOrdinalsConfig } from "js-1sat-ord";

const config: SendOrdinalsConfig = {
  paymentUtxos: [paymentUtxo],
  ordinals: [ordinalUtxo],
  paymentPk: paymentPk,
  ordPk: ordPk,
  destinations: [{
    address: destinationAddress,
    inscription: { dataB64: encodedFileData, contentType: "text/markdown" }
  }]
};

const result = await sendOrdinals(config);

Deploy a BSV21 Token

import type { DeployBsv21TokenConfig } from "js-1sat-ord";

const config: DeployBsv21TokenConfig = {
  symbol: "MYTICKER",
  icon: "<icon_outpoint>",
  utxos: [utxo],
  initialDistribution: { address: destinationAddress, amt: "1000000000" },
  paymentPk: paymentPk,
  destinationAddress: destinationAddress
};

const result = await deployBsv21Token(config);

Transfer BSV21 Tokens

import type { TransferBsv21TokenConfig } from "js-1sat-ord";

const config: TransferBsv21TokenConfig = {
  protocol: TokenType.BSV21,
  tokenID: tokenID,
  utxos: [utxo],
  inputTokens: [tokenUtxo],
  distributions: [{ address: destinationAddress, amt: "1000" }],
  paymentPk: paymentPk,
  ordPk: ordPk
};

const result = await transferOrdToken(config);

Send Utxos

Sends utxos to the given destination:

import type { SendUtxosConfig } from "js-1sat-ord";

const config: SendUtxosConfig = {
  utxos: [utxo],
  paymentPk: paymentPk,
  payments: [{ to: destinationAddress, amount: 1000 }]
};

const { tx } = await sendUtxos(config);

Additional Configuration Options

Each function accepts additional configuration options not shown in the examples above. These include:

  • changeAddress: Address to send change to (if not provided, defaults to the payment key's address)

  • satsPerKb: Satoshis per kilobyte for fee calculation

  • metaData: MAP (Magic Attribute Protocol) metadata to include in inscriptions

  • signer: Custom signer object for transaction signing

  • additionalPayments: Additional payments to include in the transaction

Refer to the function documentation for a complete list of configuration options for each function.

Using with Bundlers

Since this package depends on @bsv/sdk there should be no issue with bundlers.

There is a public 1Sat API which is documented here:
