The blockchain development landscape has just gotten significantly more accessible with the release of XDB CHAIN’s comprehensive TypeScript SDK. This developer-focused toolkit provides everything needed to build sophisticated blockchain applications on one of the most innovative and eco-friendly blockchain networks available today.

What is XDB CHAIN?

XDB CHAIN is a user-friendly, open-source blockchain platform designed to facilitate digital assets such as branded coins, NFTs, payment tokens, and more. Originally starting as a fork of the Stellar Blockchain, XDB CHAIN has evolved into a completely independent blockchain with groundbreaking features that enable seamless support for all Stellar-based blockchains.

Key Network Features:

• High Performance: Processing speed of 10,000 TPS, with plans to increase to 1.19 million TPS upon the launch of a layer 2 solution
• Eco-Friendly: Built with sustainability as a core principle
• Enterprise-Grade: Designed specifically for brands and enterprise use cases
• Cross-Chain Compatibility: Allows users from any Stellar-based blockchain to import their accounts

Introducing the TypeScript SDK

The newly released ts-xdbchain-sdk is available on both npm and GitHub, providing developers with a robust toolkit for building on XDB CHAIN. This SDK abstracts the complexity of blockchain interactions while maintaining full access to the network’s powerful features.

Market Data:

• getOffers(publicKey, options) – Retrieve account orders
• getOrderbook(selling, buying, limit) – Access market orderbooks
• getTrades(publicKey, options) – Query trade history
• getTradesForAssetPair(baseAsset, counterAsset, options) – Asset pair trading data

6. Real-Time Monitoring

The SDK includes powerful streaming capabilities for real-time applications:

Balance Monitoring:

• getBalances(publicKey) – Get all account balances
• getXDBBalance(publicKey) – Get native XDB balance
• watchBalances(publicKey, callback) – Real-time balance updates

Transaction Streaming:

• watchTransactions(publicKey, callback) – Monitor transactions in real-time
• watchPayments(publicKey, callback) – Track payment activities
• getTransactionHistory(publicKey, options) – Historical transaction data

7. Advanced Features

Claimable Balances:

• createClaimableBalance(senderSecret, claimantPublicKey, amount, asset) – Create conditional payments
• claimBalance(claimantSecret, balanceId) – Claim pending balances
• getClaimableBalances(publicKey) – Query claimable balances

Multi-Signature Support:

• signTransaction(transaction, signers) – Sign transactions with multiple keys
• createMultiSigTransaction(sourceAccount, operations, signers) – Create complex multi-signature transactions

Data Management:

• manageData(secretKey, options) – Store arbitrary data on-chain

Network Configuration

The SDK supports both mainnet and testnet environments:

Real-World Use Cases

Building a Payment Application

Creating a Trading Bot

Integration with Branded Coins (BCO)

XDB CHAIN features Branded Coins (BCO), where every new BCO allocates up to 2.5% of its total supply for regular XDB buyback and burning, creating a deflationary mechanism. The SDK provides full support for creating and managing these branded assets:
