DeFindex SDK

A TypeScript SDK for interacting with DeFindex Vaults on the Stellar Soroban network. DeFindex is a protocol for creating and managing multi-asset investment vaults with customizable strategies.

Overview

DeFindex Vaults serve as the core of the DeFindex platform, responsible for:

• Managing multiple assets
• Executing investment strategies
• Ensuring proper asset rebalancing
• Minting/burning dfTokens (vault shares)

Installation

npm install defindex-sdk
# or
yarn add defindex-sdk

Quick Start

import { Vault, SorobanNetwork } from 'defindex-sdk';

// Initialize a vault instance
const vault = new Vault({
    network: SorobanNetwork.TESTNET,
    contractId: 'YOUR_VAULT_CONTRACT_ID'
});

// Deposit assets
const txHash = await vault.deposit(
    accountAddress,
    100, // amount
    true, // signAndSend
    sorobanContext,
    secretKey
);

Features

• Asset Management: Deposit and withdraw multiple assets
• Balance Tracking: Monitor your vault share balance
• Transaction Handling: Built-in support for Soroban transactions
• Type Safety: Full TypeScript support

  • amount: Amount of dfTokens to burn
  • signAndSend: Whether to sign and submit the transaction

  • secretKey: Optional secret key for signing

• Returns: Transaction hash

balance(account: string, sorobanContext: SorobanContextType): Promise<number>

Checks the dfToken balance of an account.

• Parameters:

  • account: The account address
  • sorobanContext: Soroban context object

• Returns: Balance amount

Example Usage

import { Vault, SorobanNetwork } from 'defindex-sdk';

async function main() {
    // Initialize vault
    const vault = new Vault({
        network: SorobanNetwork.TESTNET,
        contractId: 'YOUR_CONTRACT_ID'
    });

    // Create Soroban context
    const sorobanContext = await createSorobanContext();
    
    // Check initial balance
    const balance = await vault.balance(accountAddress, sorobanContext);
    console.log('Balance:', balance);

    // Deposit assets
    const txHash = await vault.deposit(
        accountAddress,
        100,
        true,
        sorobanContext,
