GDEX: Agent Onboarding

GDEX is a cross-chain DeFi trading infrastructure for AI agents. It provides spot trading, perpetual futures (HyperLiquid), portfolio management, token discovery, copy trading, and bridging across Solana, Sui, and 12+ EVM chains — all through a single SDK with managed-custody wallets.

When to Use

• You're new to GDEX and need to understand the platform
• You need to decide which skill to load for a specific task
• You want a quick overview of supported chains and capabilities

Architecture

Agent → @gdexsdk/gdex-skill SDK → GDEX Backend (trade-api.gemach.io/v1) → On-chain Execution

Key concepts:

• Managed custody — GDEX provisions and manages all on-chain trading wallets server-side. Your control wallet only signs in once.
• Encrypted payloads — All trades use AES-256-CBC encrypted computedData payloads. The API key derives the AES key deterministically via SHA256 hash chain.
• Session keypairs — A secp256k1 session key signs trade payloads after initial control-wallet sign-in.
• Shared API keys — Pre-configured keys let agents authenticate instantly without wallet signing.

Quick Start

npm install @gdexsdk/gdex-skill

import { GdexSkill, GDEX_API_KEY_PRIMARY } from '@gdexsdk/gdex-skill';

const skill = new GdexSkill();
skill.loginWithApiKey(GDEX_API_KEY_PRIMARY);

// No-auth: check trending tokens
const trending = await skill.getTrendingTokens({ chain: 'solana', period: '24h', limit: 5 });

// Auth required: buy a token
const trade = await skill.buyToken({
  chain: 'solana',
  tokenAddress: 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v',
  amount: '0.1',
  slippage: 1,
});

Shared API Keys (pre-configured for all agents):

• Primary: 9b4e1c73-6a2f-4d88-b5c9-3e7a2f1d6c54
• Secondary: 2c8f0a91-5d34-4e7b-9a62-f1c3d8e4b705

Supported Chains

Chain IDs for managed-custody: 900 = Solana, 101 = Sui, or standard EVM chain IDs.

Tools: search_gdex_docs, get_sdk_pattern, get_api_info, explain_workflow, get_chain_info, get_trading_guide, get_copy_trade_guide, get_component_guide.

Autonomous Agent Quickstart

If you're an AI agent operating autonomously (no human to ask), here's the minimum viable flow:

1. Initialize

import { GdexSkill, GDEX_API_KEY_PRIMARY } from '@gdexsdk/gdex-skill';
const skill = new GdexSkill();
skill.loginWithApiKey(GDEX_API_KEY_PRIMARY);

2. Research Before Trading

// Check what's trending
const trending = await skill.getTrendingTokens({ chain: 622112261, period: '1h', limit: 10 });

// Get details on a token — CHECK dexId BEFORE buying
const token = await skill.getTokenDetails({ tokenAddress: trending[0].address, chain: 622112261 });
if (token.dexId === 'meteora') {
  // ❌ Meteora tokens FAIL on Solana — skip this token
}
if (token.dexId === 'raydium') {
  // ✅ Safe to buy
}

3. Full Managed-Custody Setup (for actual trading)

import { ethers } from 'ethers';
import {
  generateGdexSessionKeyPair, buildGdexSignInMessage,
  buildGdexSignInComputedData, buildGdexUserSessionData,
} from '@gdexsdk/gdex-skill';

const wallet = ethers.Wallet.fromPhrase('your mnemonic...');
const { sessionPrivateKey, sessionKey } = generateGdexSessionKeyPair();
const nonce = String(Date.now());
const msg = buildGdexSignInMessage(wallet.address, nonce, sessionKey);
const sig = await wallet.signMessage(msg);
const payload = buildGdexSignInComputedData({
  apiKey: GDEX_API_KEY_PRIMARY, userId: wallet.address, sessionKey, nonce, signature: sig,
});
await skill.signInWithComputedData({ computedData: payload.computedData, chainId: 1 });

4. Key Rules for Autonomous Operation

• Always use control wallet address (the one that signed in) for userId/walletAddress in API calls
• Never use managed wallet address in API calls (except getHlUserStats())
• Amounts in raw units for managed trades (lamports for Solana, wei for EVM)
• Check dexId before buying on Solana — skip Meteora tokens
• Generate fresh nonce for every operation
• Portfolio/balances use raw client — high-level methods send wrong params
• If hlCloseAll fails, use reduce-only order instead
