Register or login on to TAAL PLATFORM.
Your mainnet and testnet API keys will be displayed.
Enter the URL in your browser
Welcome to TAAL Docs!!
You can use these docs to learn more about TAAL’s core products, explore guides, and check our API references.
TAAL delivers value-added blockchain services, providing professional-grade, highly scalable blockchain infrastructure, and transactional solutions to support builders and businesses building on the BitcoinSV protocol.
As a Transaction processor (or miner) TAAL validates clients transactions and time stamps them by sequencing and encoding them into blocks, which are then published and added to the BSV blockchain.
TAAL API is an easy to integrate, open communication channel to the blockchain. By connecting an application to this endpoint data, in the form of transactions, can be processed, instantly verified, and once settled this data can be viewed anytime. Creating great value to applications that require real time blockchain data at scale, now and into the future.
1SatOrdinals in an implementation of Ordinals running on the BSV blockchain. The tokens represent individual satoshis (the smallest unit of Bitcoin) that are "inscribed" with specific data, such as images or text. 1Sat Ordinals on BSV are fast, inexpensive, and fully scriptable via native Bitcoin Script.
The ability to have low-cost transactions (less than a penny), which make a difference when issuers are dropping millions of NFTs, for example. This attribute means more margin for the issuers on primary and secondary markets.
Interoperability with ecosystem wallets and other blockchain platforms.
Transparency allows the token to be tracked throughout its lifecycle, which makes a difference in a regulatory environment.
No network congestion — as the tokens are issued at the network level on a blockchain that scales unbounded.
You can license this technology from TAAL, download the SDK, and start building their next game-changing NFT or digital asset platform today!

It is our goal to make it easier for anyone to provide metadata or showcase the on-chain data. We believe that by empowering the community, we will continue to unlock another aspect of the boundless potential of the Bitcoin blockchain.
To facilitate this, we have provided the ability to create and publish plugins. The plugins feature allows anyone to add more context or provide a different view/UI for transactions, blocks, addresses, OP_RETURN data, or user's searched terms.
On the Manage Plugins page, click on the "Lab" tab and fill in the required plugin details.
Data: You can create this Plugin type to decode and display the OP_RETURN output. The response provided by the plugin's webhook will be rendered when a user tries to decode the OP_RETURN data on the transactions page.
Block: This type of plugin can be used to share any metadata/stats for a given block. Appears as a new tab on the block page with the data provided by the plugin's webhook.
Address: This type of plugin can be used to share any metadata/stats for a given address. Appears as a new tab on the address page with the data provided by the plugin's webhook.
Transaction: This type of plugin can be used to share any metadata/stats for a given transaction. Appears as a new tab on the transaction page with the data provided by the plugin's webhook.
Script: This type of plugin can be used to share any metadata/stats for a given scripthash. Appears as a new tab on the scripthash page with the data provided by the plugin's webhook.
Search engine: If you are interested in sharing data from your specialized indexer, use this plugin type to help users search your indexed data when they search anything on whatsonchain.com via the search bar.
Don't forget to press "Save" after providing the required plugin details.
To Edit, Delete or Publish a plugin, click on the menu option next to the plugin name.
When a new plugin is created or is in the development phase, it is listed in the "Lab" tab. Plugins listed in the "Lab" are not available publicly and the plugin data is saved locally in the browser's local storage.
All the published plugins are listed under the "Plugins" section.

A recovery phrase is a group of words, usually 12 or more that are generated when a new crypto wallet is created. You can use the recovery phrase to retrieve your crypto accounts, using any compatible wallet.
The Passphrase is an advanced feature that adds a 13th word of your choosing to your recovery phrase.
Using a Passphrase will cause an entirely different set of addresses to be created which cannot be accessed via the 12-word recovery phrase alone.
Aside of adding another layer, the Passphrase grants you plausible deniability when under duress.
If using a Passphrase, it’s key to store it securely and remember it perfectly, character for character.
Enables user to get the latest balance reflected in the account.
Testnet only. Will send a small amount of BSV test coins to your account.

List of tech stack used
BSV-21 protocol was originally called BSV-20 v2 but was renamed for clarity.
"This iteration of the BSV-20 protocol introduces a new tickerless mode functionality. Tickerless mode forgoes the first is first nature of BRC20-BTC, and allows the capabilities to have a smart contract, or an administrator, control distribution. Additionally, every transaction of a tickerless mode token forms part of a single on-chain DAG (Directed Acyclic Graph), such that the transaction can easily be tracked back to that token's genesis mint.

Satoshis
The smallest indivisible unit of a bitcoin. 1E8 Satoshis = 1 bitcoin
Script
Low level bitcoin script.
SDK
Software Developer Kit is a software library to make certain tasks easier for a software developer.
UTXO
An Unspent Transaction Output is an amount of bitcoin that can be spent by the recipient.
Inscription ID
An outpoint representing a particular inscription, comprised of a transaction ID and output index with the following formatting: `txid_vout`
Inscription Number
This is an auto-incrementing id given to each inscription as they appear in mined blocks, starting with inscription #0. Because inscription numbers are dependent on the order of transactions in a block, inscription numbers are not assigned until a transaction is confirmed. This also makes inscription number sensitive to reorgs.
Origin
This is like a "low resolution" ordinal number. It represents the last time a particular ordinal became a 1 satoshi output. Since utxos can be split and joined over time, an ordinal can have more than one origin. This is a 1Sat protocol specific concept, not present in the original ordinals protocol.
Ordinal Number
An ordinal is an identifier given to a specific satoshi. It is given when the sat comes into existence during a coinbase transaction. To learn more about this concept read the original "ordinal theory" documentation.
Blockchain
It is a form of distributed database (or ledger) that acts as a record of all the valid transactions which are transmitted to the blockchain network.
An on-chain document representing the contract between token issuer and user.
Mint a token from an on-chain contract transaction.
The most common locking script used by default to send bitcoin.
Destroy the token and return the locked Satoshis to the issuer.
The smallest indivisible unit of a bitcoin. 1E8 Satoshis = 1 bitcoin.
Low level bitcoin script.
Software Developer Kit is a software library to make certain tasks easier for a software developer.
A token script named after its creator Stas. Also a reverse acronym: Substantiated Tokens from Actualized Satoshis.
It is a type of digital property or control element that can be transferred using a blockchain.
An Unspent Transaction Output is an amount of bitcoin that can be spent by the recipient.

Github Repository
mkdir 1sat-tutorial
cd 1sat-tutorial
Demo code using our 1Sat Token Studio API can be found on Github so you can clone our repository or if you want to do it manually, we need to make now a node project
npm init
and answer in the questions.
Let’s add the dependencies
npm install bsv@1.5.4
npm install axios
Make sure your package.json looks like this (you might need to change the type to “module” and add a new entry to run the tutorial- "tutorial": "node index.js"
{ "name": "1sat-tutorial",
"version": "1.0.0",
"description": "1sat-tutorial",
"type": "module",
"main": "index.js",
"scripts": { "test": "echo \"Error: no test specified\" && exit 1",
"tutorial": "node index.js"
},
"author": "TAAL",
"license": "ISC",
"dependencies": {
"dependencies": { "axios": "^1.7.2",
"bsv": "^1.5.4"
}
}
Now we are ready to start coding. Create the main file you specified during the setup e.g. index.jsin the root of the 1sat-tutorial folder as well as the helping file 1sat_utils.cjs using your editor or IDE of choice.
Copy the code from our files and paste.
in index.js you will need to replace the sample API key from your TAAL API Key
You can also tune which steps to run, only the creation of a single/standalone token, the inscription of a collection with one item or individual steps you may want to debug in depth e.g.
const STEPS_TO_TEST =[ 'single', 'collection'];
///const STEPS_TO_TEST =['1.1','1.2','1.3','1.4','1.5', '1.6', '1.7']; //const STEPS_TO_TEST =['2.1','2.2','2.3','2.4','2.5', '2.6', '2.7', '2.8', '2.9'];
You can test now. If all was properly configured you should see something like this:

The current standard fee rate which applies to all transactions submitted to any of the TAAL transaction processing APIs is: 1 sat/kb
The minimum fee for any transaction is 1 sat.
The fee required is rounded depending on size of the transaction. The following list exemplifies the logic:
Transactions with 1.4999... kb > size > 0.0 kb => min absolute fee required = 1 sat.
Transactions with 2.4999... kb > size > 1.5 kb => min absolute fee required = 2 sat
Transactions with 3.4999... kb > size > 2.5 kb => min absolute fee required = 3 sat
...
