1Sat Ordinals - JS Library

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

It provides functions for listing, cancelling and purchasing Ordinal Lock transactions.

It also privides helpers for fetching utxos for payments, nfts, and tokens.

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 (base64). This should be a BSV address, not your ordinals address. Note: By default the script encoding will be base64, but you can provide a 2nd parameter and specify hex or asm encoding for the script property.

Note: Utxo and NftUtxo and TokenUtxo have an optional pk field for specifying a Private Key for unlocking this utxo. This is helpful when multiple keys own the inputs and you need to spend them in a single traqnsaction.

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

const utxos = await fetchPayUtxos(payAddress)

For NFTUtxos:

import { fetchNftUtxos } from "js-1sat-ord"

// collectionId is optional
const collectionId = "1611d956f397caa80b56bc148b4bce87b54f39b234aeca4668b4d5a7785eb9fa_0"
const nftUtxos = await fetchNftUtxos(ordAddress, collectionId)

For Token Utxos:

import { fetchTokenUtxos, type TokenType } from "js-1sat-ord"

const protocol = TokenType.BSV21;
const tokenId = "e6d40ba206340aa94ed40fe1a8adcd722c08c9438b2c1dd16b4527d561e848a2_0";
const tokenUtxos = await fetchTokenUtxos(protocol, tokenId, ordAddress);

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, tokens: 10 },
  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, tokens: 0.1 }],
  paymentPk: paymentPk,
  ordPk: ordPk
};

const result = await transferOrdToken(config);

Note: To burn tokens you can set the optional burn parameter to true Note: You can use the optional splitConfig parameter to configure how and when to split token change outputs, and whether change outputs should include metadata. Note: You can use the optional tokenInputMode parameter to configure whether all tokens are consumed, or only what's needed. Default is needed.

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);

Create Ordinal Listings

Creates a listing using an "Ordinal Lock" script. Can be purchased by anyone by sending a specific amount to the provided address.

const listings = [{
  payAddress: addressToReceivePayment;
  price: 100000; // price in satoshis
  listingUtxo,
  ordAddress: returnAddressForCancel;
}]

const config: CreateOrdListingsConfig = {
  utxos: [utxo],
  listings,
  paymentPk,
  ordPk,
}

const { tx } = await createOrdListings(config);

Purchase Ordinal Listing

const config: PurchaseOrdListingConfig ={
  utxos: [utxo], 
  paymentPk, 
  listingUtxo, 
  ordAddress,
};

const { tx } = await purchaseOrdListing(config);

Cancel Ordinal Listings

Spends the ordinal lock without payment, returning the ordinal to the address specified in the listing contract.

const config: CancelOrdListingsConfig = { utxos, listingUtxos, ordPk, paymentPk };
const { tx } = await cancelOrdListings(config);

Additional Configuration Options

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

Broadcasting

import { oneSatBroadcaster } from "js-1sat-ord"

// ...

const { status, txid, message  } = await tx.broadcast(oneSatBroadcaster())

Using with Bundlers

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