@leapwallet/ondo-gm-core

Core package providing fundamental building blocks for Ondo protocol integration - transaction clients, query utilities, state management, and TypeScript types.

Features

• 🔧 Transaction Clients: Prepare and execute Ondo protocol transactions
• 📊 Query Utilities: TanStack Query configurations for API data fetching
• 🏪 State Management: MobX-based state stores for application data
• 📝 TypeScript Types: Comprehensive type definitions for all Ondo protocol entities

Installation

npm install @leapwallet/ondo-gm-core
# or
pnpm add @leapwallet/ondo-gm-core
# or
yarn add @leapwallet/ondo-gm-core

Quick Start

Basic Setup

import { OndoGMApi } from '@leapwallet/ondo-gm-core';

// Initialize the API client
const apiClient = new OndoGMApi({
  baseUrl: 'https://api.ondo.finance',
});

Query Utilities

The core package provides pre-configured query options for use with TanStack Query:

import { useQuery } from '@tanstack/react-query';

import { getAssetPriceQuery, getAssetsQuery } from '@leapwallet/ondo-gm-core';

// Fetch all asset prices
const assetsQuery = getAssetsQuery(apiClient);
const { data: assets } = useQuery(assetsQuery);

// Fetch specific asset price
const assetPriceQuery = getAssetPriceQuery(apiClient, {
  asset: 'USDC',
});
const { data: price } = useQuery(assetPriceQuery);

Transaction Client

import { ChainType, type TransactionParams } from '@leapwallet/ondo-gm-core';

// Prepare transaction parameters
const transactionParams: TransactionParams = {
  chainId: '1',
  fromAddress: '0x...',
  toAddress: '0x...',
  amount: '1000000', // 1 USDC (6 decimals)
  // ... other required fields
};

// Transaction preparation and execution would be handled by chain-specific clients
// (see @leapwallet/ondo-gm-evm-client for EVM implementation)

State Management

import { OndoGMState } from '@leapwallet/ondo-gm-core';

// Access the global state store
const store = OndoGMState.baseState;

// The state is observable with MobX
// Use with @leapwallet/ondo-gm-react-adapter for React integration

API Reference

Query Functions

• getAssetsQuery(apiClient, options?) - Fetch all asset prices
• getAssetPriceQuery(apiClient, query) - Fetch specific asset price
• getMarketQuery(apiClient, query) - Fetch market data
• getOHLCQuery(apiClient, query) - Fetch OHLC (candlestick) data
• getAccountQuery(apiClient, query) - Fetch account information

Transaction Types

• ChainType - Supported blockchain types (ETHEREUM, SOLANA)
• TransactionParams - Parameters for transaction preparation
• PreparedTransaction<T> - Prepared transaction with gas estimates

State Stores

• OndoGMState.baseState - Global application state store

Type Definitions

The package exports comprehensive TypeScript types for all Ondo protocol entities, generated from the OpenAPI specification.

import type { Account, Asset, Attestation, Market, OHLCData } from '@leapwallet/ondo-gm-core';
