🌟 Key Features
✅ Universal EVM Wallet - ONE custodial address works for ALL EVM chains
✅ Base Trading - Fully tested and working (verified transactions)
✅ Solana Meme Coins - Including pump.fun pre-DEX tokens
✅ Limit Orders - Take profit & stop loss support
✅ Copy Trading - Automatically follow top traders
✅ Real-Time Data - WebSocket streams + comprehensive analytics
✅ HyperLiquid Futures - Opening leveraged positions WORKING! (Feb 26, 2026)
Installation
Install as a Claude skill (recommended):
npx skills add GemachDAO/gdex-trading-
This registers the skill with Claude Code so it can be invoked automatically for trading tasks. It also counts toward the skill's leaderboard ranking.
Or clone and run directly:
git clone https://github.com/GemachDAO/gdex-trading-.git
cd gdex-trading-
npm install
cp .env.example .env
npm test
SDK only (for embedding in your own project):
npm install gdex.pro-sdk ethers ws
🔑 Pre-Provided API Key (No Sign-Up Required)
A shared API key is included — no account or sign-up needed:
GDEX_API_KEY=3f6c9e12-7b41-4c2a-9d5e-1a8f3b7e6c90,8d2a5f47-2e13-4b9c-a6f1-0c9e7d3a5b21
This key is already the default in src/config.ts and pre-filled in .env.example.
Wallets are auto-generated on first run — no wallet setup needed either.
API Connectivity Requirements (Critical for Agents)
All requests to trade-api.gemach.io must include a browser-like User-Agent header. Without it the API returns 403 "Access denied: Non-browser clients not allowed". Additionally, Origin and Referer headers are required for CORS.
Required Headers
| Header | Value | Required? |
|---|
User-Agent | A Chrome/Firefox browser UA string | YES — all requests (primary gatekeeper) |
Origin | https://gdex.pro | YES — all requests (CORS) |
Referer | https://gdex.pro/ | YES — all requests (CORS) |
createAuthenticatedSession() and initSDK() inject these automatically. For direct axios/fetch calls:
const GDEX_HEADERS = {
'Origin': 'https://gdex.pro',
'Referer': 'https://gdex.pro/',
'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/122.0.0.0 Safari/537.36',
};
await axios.get('https://trade-api.gemach.io/v1/status', { headers: GDEX_HEADERS });
Health Check
Use GET /v1/status → {"running":true} or sdk.tokens.getNativePrices(). Do NOT use /v1/health — returns 404.
🔑 Critical: Universal Custodial Wallet System
IMPORTANT FOR AGENTS: GDEX uses TWO wallet addresses - understanding this is critical!
Your Control Wallet (from .env)
- Address you control with private key
- Used for authentication only
- Example:
0x01779499970726ff4C111dDF58A2CA6c366b0E20
GDEX Custodial Wallets (GDEX controls)
- ONE address for ALL EVM chains ← This is the game changer!
- Different address for Solana
- Send funds HERE to trade
- Auto-processed in 1-10 minutes
Get Your Custodial Addresses
Quick command:
npm run wallets:qr
Programmatic:
const session = await createAuthenticatedSession({ chainId: 42161 });
const userInfo = await session.sdk.user.getUserInfo(
session.walletAddress, session.encryptedSessionKey, 42161
);
const evm_custodial = userInfo.address;
const solSession = await createAuthenticatedSession({ chainId: 622112261 });
const solUserInfo = await solSession.sdk.user.getUserInfo(
solSession.walletAddress, solSession.encryptedSessionKey, 622112261
);
const sol_custodial = solUserInfo.address;
Funding for Multi-Chain Trading
For ANY EVM chain (Base, Arbitrum, Ethereum, BSC, Optimism):
- Send ETH, USDC, or any token to your EVM custodial address
- Use the network you want to trade on
- Same address works across ALL EVM chains!
For Solana:
- Send SOL to your Solana custodial address
- Works for all Solana tokens including pump.fun
Authentication Architecture (Critical)
The SDK uses EVM (secp256k1) signing internally for ALL chains, including Solana. You must always use an EVM wallet (0x-prefixed address) even when trading on Solana.
The authentication flow produces a session that separates concerns:
- Wallet private key — used ONLY for the one-time login signature
- Session private key — used for all trading POST requests (buy, sell, limit orders)
- Encrypted session key — used for authenticated GET requests (holdings, orders, user info)
Never pass the wallet private key to trading functions. Use the session's tradingPrivateKey instead.
Quick Start
The fastest way to authenticate and trade:
import { createAuthenticatedSession, buyToken, formatSolAmount } from 'gdex-trading';
const session = await createAuthenticatedSession({
apiKey: process.env.GDEX_API_KEY || '3f6c9e12-7b41-4c2a-9d5e-1a8f3b7e6c90,8d2a5f47-2e13-4b9c-a6f1-0c9e7d3a5b21',
walletAddress: process.env.WALLET_ADDRESS,
privateKey: process.env.PRIVATE_KEY,
chainId: 622112261,
});
const result = await buyToken(session, {
tokenAddress: 'PASTE_SOLANA_MINT_ADDRESS_HERE',
amount: formatSolAmount(0.005),
});
if (result.isSuccess) {
console.log('Transaction hash:', result.hash);
}
Manual Authentication
If you need more control over the login flow:
import WebSocket from 'ws';
(globalThis as any).WebSocket = WebSocket;
import { createSDK, CryptoUtils } from 'gdex.pro-sdk';
import { ethers } from 'ethers';
const apiKey = process.env.GDEX_API_KEY!.split(',')[0].trim();
const sdk = createSDK('https://trade-api.gemach.io/v1', { apiKey });
const sessionKeyPair = CryptoUtils.getSessionKey();
const publicKeyHex = Buffer.from(sessionKeyPair.publicKey).toString('hex');
const nonce = CryptoUtils.generateUniqueNumber();
const wallet = new ethers.Wallet(process.env.PRIVATE_KEY!);
const address = process.env.WALLET_ADDRESS!;
const message = `By signing, you agree to GDEX Trading Terms of Use and Privacy Policy. Your GDEX log in message: ${address.toLowerCase()} ${nonce} ${publicKeyHex}`;
const signature = await wallet.signMessage(message);
const userInfo = await sdk.user.login(
address,
nonce,
'0x' + publicKeyHex,
signature,
'',
622112261
);
const encryptedSessionKey = CryptoUtils.encrypt('0x' + publicKeyHex, apiKey);
const tradingPrivateKey = sessionKeyPair.privateKey.toString('hex');
const buyResult = await sdk.trading.buy(
address,
'5000000',
'TOKEN_ADDRESS_HERE',
622112261,
tradingPrivateKey
);
Core Capabilities
1. Token Operations
Get market data, search tokens, analyze trends, and retrieve price information across all supported chains.
import { createSDK } from 'gdex.pro-sdk';
const sdk = createSDK('https://trade-api.gemach.io/v1');
const trending = await sdk.tokens.getTrendingTokens(10);
const results = await sdk.tokens.searchTokens('PEPE', 10);
const token = await sdk.tokens.getToken('TOKEN_ADDRESS', chainId);
const prices = await sdk.tokens.getNativePrices();
const newest = await sdk.tokens.getNewestTokens(622112261, 1, undefined, 10);
2. Trading Operations
Execute market orders and limit orders. All trading functions require a session — see Quick Start above.
import {
createAuthenticatedSession,
buyToken,
sellToken,
createLimitBuyOrder,
createLimitSellOrder,
getOrders,
formatSolAmount,
formatEthAmount,
} from 'gdex-trading';
const session = await createAuthenticatedSession();
const buy = await buyToken(session, {
tokenAddress: 'TOKEN_ADDRESS',
amount: formatSolAmount(0.005),
});
const sell = await sellToken(session, {
tokenAddress: 'TOKEN_ADDRESS',
amount: '1000000',
});
const limitBuy = await createLimitBuyOrder(session, {
tokenAddress: 'TOKEN_ADDRESS',
amount: formatSolAmount(0.01),
triggerPrice: '0.002',
profitPercent: 20,
lossPercent: 10,
});
const limitSell = await createLimitSellOrder(session, {
tokenAddress: 'TOKEN_ADDRESS',
amount: '500000000',
triggerPrice: '0.005',
});
const orders = await getOrders(session);
Or using the raw SDK with a session's trading key:
const buyResult = await session.sdk.trading.buy(
session.walletAddress,
'5000000',
'TOKEN_ADDRESS',
622112261,
session.tradingPrivateKey
);
const limitResult = await session.sdk.trading.createLimitSell(
session.walletAddress,
'500000000',
'0.002',
'TOKEN_ADDRESS',
622112261,
session.tradingPrivateKey
);
3. Copy Trading
Automatically copy trades from top-performing traders on supported chains.
const session = await createAuthenticatedSession();
const topTraders = await session.sdk.copyTrade.getTopTraders(622112261);
const copyTrade = await session.sdk.copyTrade.createCopyTrade(
session.walletAddress,
'0xTraderAddress',
'Top Trader Copy',
'20',
1,
'1000000000',
false,
'10',
'20',
true,
[],
622112261,
session.tradingPrivateKey
);
const copyTrades = await session.sdk.copyTrade.getCopyTradeList(
session.walletAddress,
session.encryptedSessionKey
);
4. Solana Meme Coin Trading (VERIFIED WORKING)
Buy and sell meme coins on Solana, including pump.fun tokens still on bonding curve. This flow has been tested and confirmed working with multiple verified transactions.
SDK: gdex.pro-sdk | Endpoint: https://trade-api.gemach.io/v1 | Chain ID: 622112261
Pump.fun tokens WORK — isListedOnDex: false tokens on the bonding curve trade fine through GDEX. No need to wait for DEX graduation.
⚠️ CRITICAL (Mar 2026): The old POST /purchase SDK endpoint returns 401 { error: 'Unsupported token' } for Token2022 tokens, which are now 88%+ of all pump.fun tokens. buyToken() and sellToken() automatically use the v2 async endpoints (POST /purchase_v2 + POST /sell_v2) for Solana, which handle Token2022 and Raydium LaunchLab tokens correctly. Do not call sdk.trading.buy() directly for Solana — always use the buyToken() wrapper.
import { createAuthenticatedSession, buyToken, sellToken, formatSolAmount } from 'gdex-trading';
let session;
try {
session = await createAuthenticatedSession({ chainId: 622112261 });
} catch {
session = await createAuthenticatedSession({ chainId: 42161 });
}
const newest = await session.sdk.tokens.getNewestTokens(622112261, 1, undefined, 20);
const sorted = [...newest].sort((a, b) => (b.txCount || 0) - (a.txCount || 0));
const target = sorted[0];
const buyResult = await buyToken(session, {
tokenAddress: target.address,
amount: formatSolAmount(0.005),
chainId: 622112261,
});
await new Promise(r => setTimeout(r, 5000));
const sellResult = await sellToken(session, {
tokenAddress: target.address,
amount: formatSolAmount(0.005),
chainId: 622112261,
});
Verified transactions (all successful):
- Buy COMPOZY (pump.fun, 75% bonding curve):

- Buy Detectarena.ai (Token2022, via
/purchase_v2, Mar 2026): 5LNCnudBsX2adMfvZjc4w4Bhw8s2HayNbGSCH9NJds9eTMsCqU3nQGL1XJfFTLVP5WY2UGkw86VyaStb3BBzi9Ad
Key details:
buyToken() / sellToken() in src/trading.ts use POST /purchase_v2 + POST /sell_v2 for Solana (async + polling) — not sdk.trading.buy() directly- The v2 flow: POST → get
requestId → poll GET /trade-status/:requestId until success/error
- Default slippage: 2000 bps (20%) — set
slippageBps to override; optional tip in SOL for priority
- Uses
session.tradingPrivateKey (session key), NOT wallet private key
- Amount is in lamports (0.005 SOL = 5,000,000 lamports)
- The GDEX backend executes on-chain via its custodial Solana wallet
- Token2022 tokens work (confirmed Mar 2026) — v2 handles them; old
/purchase does NOT
- Pump.fun tokens work even with
isListedOnDex: false and bondingCurveProgress < 100%
Token selection strategy (best to worst):
- Sort by
txCount — higher = more activity = better liquidity
- Prefer higher
bondingCurveProgress — closer to graduation = more reserves
- Check
marketCap > 1000 — avoid dead/abandoned tokens
isListedOnDex, isRaydium, isMeteora, isPumpSwap flags indicate DEX graduation (nice-to-have but NOT required)

5. EVM Chain Trading (Base, Ethereum, BSC, etc.) - ✅ FULLY WORKING
ALL EVM chains use the SAME custodial wallet! This is revolutionary - fund once, trade everywhere.
Verified Base Chain Trading
Base trading is fully tested and working with verified on-chain transactions.
import { createAuthenticatedSession, buyToken, sellToken, formatEthAmount } from 'gdex-trading';
const session = await createAuthenticatedSession({ chainId: 8453 });
const tokens = await session.sdk.tokens.getNewestTokens(8453, 1, undefined, 50);
const tradeable = tokens.filter(t => t.priceUsd > 0);
const buyResult = await buyToken(session, {
tokenAddress: tradeable[0].address,
amount: formatEthAmount(0.00001),
chainId: 8453,
});
const sellResult = await sellToken(session, {
tokenAddress: tradeable[0].address,
amount: formatEthAmount(0.00001),
chainId: 8453,
});
Verified Base transactions:
Same Wallet for All EVM Chains
The custodial address from getUserInfo() works for:
- ✅ Base (8453)
- ✅ Arbitrum (42161)
- ✅ Ethereum (1)
- ✅ BSC (56)
- ✅ Optimism (10)
- ✅ Fraxtal (252)
- ✅ Any other EVM chain
const userInfo = await session.sdk.user.getUserInfo(
session.walletAddress,
session.encryptedSessionKey,
42161
);
const custodialAddress = userInfo.address;
Funding for EVM Trading
- Send ETH, USDC, or tokens to your custodial address
- Use ANY EVM network (Base, Arbitrum, Ethereum, etc.)
- GDEX processes in 1-10 minutes
- Trade immediately on that network
Quick command:
npm run wallets:qr
npm run base:trade
npm run base:balance
6. HyperLiquid Perpetual Futures - ✅ FULLY WORKING (Feb 26, 2026)
FULLY WORKING: Deposit, open leveraged positions, and cancel orders all verified.
✅ DEPOSIT TO HYPERLIQUID - WORKING!
Endpoint: POST /v1/hl/deposit
Working Implementation:
const encodedData = CryptoUtils.encodeInputData("hl_deposit", {
chainId: 42161,
tokenAddress: "0xaf88d065e77c8cC2239327C5EDb3A432268e5831",
amount: "10000000",
nonce: generateNonce().toString()
});
const userId = session.walletAddress.toLowerCase();
const signature = CryptoUtils.sign(`hl_deposit-${userId}-${encodedData}`, session.tradingPrivateKey);
const payload = { userId, data: encodedData, signature, apiKey };
const computedData = encrypt(JSON.stringify(payload), apiKey);
await axios.post(`${apiUrl}/hl/deposit`, { computedData }, {
headers: {
'Origin': 'https://gdex.pro',
'Referer': 'https://gdex.pro/',
}
});
Note: These headers are required for ALL API requests, not just HyperLiquid endpoints. When using createAuthenticatedSession() / initSDK(), they are injected automatically. Only add them manually for direct axios/fetch calls.
Status: ✅ VERIFIED WORKING - Successfully deposited $10 USDC to HyperLiquid custodial account
Script: src/deposit-hl-correct.ts
Command: npm run deposit:hl 10
✅ LEVERAGED POSITION OPENING - WORKING! (Feb 26, 2026)
Endpoint: POST /v1/hl/create_order
Status: ✅ VERIFIED WORKING - Orders successfully placed on HyperLiquid
Critical Requirements:
- Browser User-Agent —
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7)...Chrome/122.0.0.0 (axios UA gets 403)
apiKey in payload — { userId, data, signature, apiKey } (not just { userId, data, signature })- Numeric-style nonce —
Date.now() + Math.floor(Math.random() * 1000) as number
- Custodial address for open_orders — query
?address=CUSTODIAL_ADDR not control wallet
- Min order value — price × size ≥ $11
Working Implementation:
import { createHash, createCipheriv } from 'crypto';
import { CryptoUtils } from 'gdex.pro-sdk';
import axios from 'axios';
const GDEX_HEADERS = {
'Origin': 'https://gdex.pro',
'Referer': 'https://gdex.pro/',
'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/122.0.0.0 Safari/537.36',
};
function deriveKeyAndIv(apiKey: string) {
const hashAPI = createHash('sha256').update(apiKey).digest('hex');
const key = Buffer.from(hashAPI.slice(0, 64), 'hex');
const ivHash = createHash('sha256').update(hashAPI).digest('hex').slice(0, 32);
const iv = Buffer.from(ivHash, 'hex');
return { key, iv };
}
function encrypt(data: string, apiKey: string): string {
const { key, iv } = deriveKeyAndIv(apiKey);
const cipher = createCipheriv('aes-256-cbc', key, iv);
let encrypted = cipher.update(data, 'utf8', 'hex');
encrypted += cipher.final('hex');
return encrypted;
}
const session = await createAuthenticatedSession({ chainId: 622112261 });
const apiKey = process.env.GDEX_API_KEY!.split(',')[0].trim();
const userId = session.walletAddress.toLowerCase();
const priceRes = await axios.get(`${apiUrl}/hl/meta_and_asset_ctxs?dex=`, { headers: GDEX_HEADERS });
const ethPrice = parseFloat(priceRes.data?.data?.[1]?.[1]?.markPx || '2050');
const nonce = Date.now() + Math.floor(Math.random() * 1000);
const limitPrice = (ethPrice * 0.5).toFixed(1);
const params = {
coin: 'ETH', isLong: true, price: limitPrice, size: '0.013',
reduceOnly: false, nonce: nonce.toString(),
tpPrice: '0', slPrice: '0', isMarket: false,
};
const encodedData = CryptoUtils.encodeInputData('hl_create_order', params);
const signature = CryptoUtils.sign(`hl_create_order-${userId}-${encodedData}`, session.tradingPrivateKey);
const payload = { userId, data: encodedData, signature, apiKey };
const computedData = encrypt(JSON.stringify(payload), apiKey);
const res = await axios.post(`${apiUrl}/hl/create_order`, { computedData },
{ headers: { ...GDEX_HEADERS, 'Content-Type': 'application/json' } });
Cancel Order (works for any order — including previous sessions — via explicit orderId):
const cancelNonce = Date.now() + Math.floor(Math.random() * 1000);
const cancelParams = { nonce: cancelNonce.toString(), coin: 'ETH', orderId: order.oid.toString() };
const cancelEncoded = CryptoUtils.encodeInputData('hl_cancel_order', cancelParams);
const cancelSig = CryptoUtils.sign(`hl_cancel_order-${userId}-${cancelEncoded}`, session.tradingPrivateKey);
const cancelPayload = { userId, data: cancelEncoded, signature: cancelSig, apiKey };
const cancelComputed = encrypt(JSON.stringify(cancelPayload), apiKey);
await axios.post(`${apiUrl}/hl/cancel_order`,
{ computedData: cancelComputed, isCancelAll: false },
{ headers: { ...GDEX_HEADERS, 'Content-Type': 'application/json' } });
Script: src/test-create-order.ts
Command: npm run hl:order
Note: Open orders appear under the EVM custodial address, not the control wallet. Query with GET /hl/open_orders?address=CUSTODIAL_ADDR&dex=
Orphan cleanup: Test/dev orders accumulate across sessions. Run npm run hl:cancel-orphans to cancel all open orders at once (queries HL public API for the full order list, then cancels each by orderId).
Endpoint Status
| Endpoint | Open | Close | Status |
|---|
/v1/hl/deposit | N/A | N/A | ✅ WORKING |
/v1/hl/create_order | ✅ | N/A | ✅ WORKING (Feb 26, 2026) |
/v1/hl/cancel_order | N/A | ✅ | ✅ WORKING (any order by explicit orderId) |
hlPlaceOrder (reduceOnly=true) | ❌ | ✅ | SDK close only |
hlCreateOrder (SDK method) | ❌ | ❌ | Broken — use REST endpoint |
hlDeposit() (SDK method) | ❌ | ❌ | Broken — use /v1/hl/deposit |
What WORKS:
- ✅ Opening leveraged positions via
/v1/hl/create_order ← NEW as of Feb 26, 2026!
- ✅ Depositing to HyperLiquid via
/v1/hl/deposit
- ✅ Cancelling orders via
/v1/hl/cancel_order
- ✅ Closing positions:
hlPlaceOrder with reduceOnly=true
- ✅ Balance/position queries
- ✅ Copy trading
- ✅ Withdrawals
- ✅ Close all positions
What DOESN'T work (legacy SDK methods):
- ❌
hlPlaceOrder with reduceOnly=false → error 102
- ❌
hlCreateOrder (SDK method) → "Sent order failed"
- ❌
hlDeposit() (SDK method) → "Unauthorized"
Closing Positions (WORKS)
const session = await createAuthenticatedSession({ chainId: 42161 });
await session.sdk.hyperLiquid.hlPlaceOrder(
session.walletAddress,
'ETH',
false,
'2100',
'0.01',
true,
session.tradingPrivateKey
);
await session.sdk.hyperLiquid.hlCloseAll(
session.walletAddress,
session.tradingPrivateKey
);
Balance & Position Queries (WORKS)
const session = await createAuthenticatedSession({ chainId: 42161 });
const hlBalance = await session.sdk.hyperLiquid.getHyperliquidUsdcBalance(session.walletAddress);
const gbotBalance = await session.sdk.hyperLiquid.getGbotUsdcBalance(session.walletAddress);
const state = await session.sdk.hyperLiquid.getHyperliquidClearinghouseState(session.walletAddress);
const orders = await session.sdk.hyperLiquid.getHyperliquidOpenOrders(session.walletAddress);
const stats = await session.sdk.hyperLiquid.getHyperliquidUserStats(session.walletAddress);
const btcPrice = await session.sdk.hyperLiquid.getHyperliquidMarkPrice('BTC');
const prices = await session.sdk.hyperLiquid.getMultipleHyperliquidMarkPrices(['BTC', 'ETH', 'SOL']);
const leaders = await session.sdk.hyperLiquid.getHyperliquidLeaderboard('week', 10, 'desc', 'pnl');
Copy Trading on HyperLiquid (WORKS - opens positions indirectly)
await session.sdk.hyperLiquid.hlCreate(
session.walletAddress,
'0xTraderWallet',
'HL Copy #1',
1,
'100000000',
'10',
'20',
false,
session.tradingPrivateKey
);
Custodial Deposit Flow
const userInfo = await session.sdk.user.getUserInfo(
session.walletAddress, session.encryptedSessionKey, 42161
);
const depositAddress = userInfo.address;
const usdc = new ethers.Contract(
'0xaf88d065e77c8cC2239327C5EDb3A432268e5831',
['function transfer(address to, uint256 amount) returns (bool)'],
wallet
);
const tx = await usdc.transfer(depositAddress, ethers.parseUnits('5', 6));
await tx.wait();
Deposit Requirements: Min 5 USDC, Arbitrum only, needs ETH for gas.
New @gdex/sdk (PENDING - api.gdex.io not live yet)
The @gdex/sdk package (github:TheArcadiaGroup/gdex-sdk) is installed but targets api.gdex.io which doesn't resolve yet. Once live, it should support opening leveraged positions via client.createOrder(). The SDK is already installed and built at node_modules/@gdex/sdk/.
❌ Methods That DON'T Work
await sdk.hyperLiquid.hlDeposit(address, tokenAddress, amount, chainId, privateKey);
await sdk.hyperLiquid.hlPlaceOrder(addr, 'BTC', true, '50000', '0.1', false, key);
await sdk.hyperLiquid.hlCreateOrder(addr, 'BTC', true, '50000', '0.1', '0', '0', false, true, key);

Data sources:
sdk.connectWebSocketWithChain(622112261) → newTokensData, effectedTokensData eventssdk.tokens.getNewestTokens(622112261, page, undefined, 20) → polled every 10s, pages 1-3sdk.tokens.getToken(address, chainId) → individual token details (includes sentiment)
Implementation: src/solana-scanner.ts — single self-contained file with TokenStore, WSManager, PollingManager, TradeExecutor, Renderer, and InputHandler classes.
Multi-Agent Autonomous System — npm run pumpfun:alpha
A 6-agent autonomous trading system that runs continuously, scoring and trading pump.fun tokens.
Command: npm run pumpfun:alpha
Agents (all run in parallel as child processes):
| Agent | Script | Role |
|---|
| SCANNER | pumpfun-scanner.ts | Polls getNewestTokens every 30s, tracks prices via WebSocket, writes /tmp/pumpfun-watchlist.json |
| ANALYST | pumpfun-analyst.ts | Scores tokens 0–100 (bonding curve, txCount, mcap, velocity, security), writes /tmp/pumpfun-scores.json |
| TRADER | pumpfun-trader.ts | Buys tokens scoring >60, manages up to 5 positions, auto-exits at TP/SL |
| SCALPER | pumpfun-scalper.ts | Fast scalper targeting tokens <2 min old with +10% TP / -3% SL / 30s max hold |
| RISK | pumpfun-risk.ts | Circuit breaker — halts trading on consecutive losses or daily loss limits |
| ANALYTICS | pumpfun-analytics.ts | Tracks P&L, win rate, and writes stats to /tmp/pumpfun-stats.json |
Shared state (JSON files in /tmp/):
/tmp/pumpfun-watchlist.json — current token universe/tmp/pumpfun-scores.json — analyst scores/tmp/pumpfun-positions.json — trader open positions/tmp/pumpfun-scalp-positions.json — scalper positions/tmp/pumpfun-log.json — trade history/tmp/pumpfun-balance.json — wallet balance snapshot/tmp/pumpfun-stats.json — running P&L stats
Requirements: Solana custodial wallet must have >0.01 SOL. System runs until Ctrl-C.
Individual agents can also run standalone:
npm run pumpfun:scanner
npm run pumpfun:analyst
npm run pumpfun:trader
npm run pumpfun:scalper
8. Real-Time WebSocket Data
Stream live token data and market updates.
Important: Node.js requires a WebSocket polyfill — this is handled automatically by createAuthenticatedSession() and initSDK().
import WebSocket from 'ws';
(globalThis as any).WebSocket = WebSocket;
import { createSDK } from 'gdex.pro-sdk';
const sdk = createSDK('https://trade-api.gemach.io/v1');
await sdk.connectWebSocketWithChain(622112261);
const wsClient = sdk.getWebSocketClient();
wsClient.on('message', (data) => {
if (data.newTokensData) {
console.log('New tokens:', data.newTokensData);
}
if (data.effectedTokensData) {
console.log('Token updates:', data.effectedTokensData);
}
});
sdk.disconnect();
9. User Management
Handle portfolio tracking, watchlists, and settings.
import { createAuthenticatedSession, getHoldings, getUserInfo } from 'gdex-trading';
const session = await createAuthenticatedSession();
const holdings = await getHoldings(session);
const userInfo = await getUserInfo(session);
const watchlist = await session.sdk.user.getWatchList(
session.walletAddress,
session.chainId
);
await session.sdk.user.addWatchList(
session.walletAddress,
'TOKEN_ADDRESS',
true,
622112261,
session.tradingPrivateKey
);

Amount Formatting
Amounts must be in smallest unit as strings:
| Chain | Decimals | Example | Helper |
|---|
| Solana | 9 | 1 SOL = "1000000000" | formatSolAmount(1) |
| EVM (ETH/BNB) | 18 | 1 ETH = "1000000000000000000" | formatEthAmount(1) |
| USDC (Arbitrum) | 6 | 5 USDC = 5000000 (5 * 1e6) | ethers.parseUnits('5', 6) |
Critical: Use 1e6 not 1^6!
- Correct:
5 * 1e6 = 5,000,000 (exponential notation)
- Wrong:
5 * 1^6 = 5 (exponentiation always equals 1)
HyperLiquid:
- Deposits: Use custodial flow (send USDC to deposit address)
- Minimum: 5 USDC
- Withdrawals:
hlWithdraw() - no decimal multiplication needed
Common Gotchas
-
Solana custodial wallet needs SOL for gas — The custodial wallet (getUserInfo().address on chain 622112261) must hold enough SOL to pay for transaction fees and token account creation. If buys fail with isSuccess: false, check the balance first. Recommend keeping >0.01 SOL in the custodial wallet. Token2022 tokens (all modern pump.fun tokens) trade fine once funded via the v2 endpoints.
-
"Unsupported token" (401) — The old POST /purchase endpoint doesn't support Token2022 tokens (88%+ of pump.fun tokens as of Mar 2026). Always use buyToken() / sellToken() from src/trading.ts — they auto-route Solana through POST /purchase_v2 / POST /sell_v2. Never call sdk.trading.buy() directly for Solana.
Check balance:
npm run wallets:qr
const session = await createAuthenticatedSession({ chainId: 622112261 });
const info = await session.sdk.user.getUserInfo(
session.walletAddress, session.encryptedSessionKey, 622112261
);
const custodialAddr = info.address;
-
HyperLiquid deposits use custodial flow — Do NOT use sdk.hyperLiquid.hlDeposit() directly! It will fail with "Unauthorized" errors. Instead, get your deposit address from getUserInfo() and send USDC to that address on Arbitrum. GDEX processes it automatically (1-10 minutes). Minimum: 5 USDC. See section 4 above for complete implementation.
-
EVM wallets for all chains — The SDK uses secp256k1 signing internally, even for Solana. Always use a 0x-prefixed EVM wallet address.
-
Session key vs wallet key — The wallet private key is ONLY for the login signature. Trading uses the session key's private key (session.tradingPrivateKey). Passing the wallet key to sdk.trading.buy() will fail.
-
Comma-separated API keys — The .env file may contain multiple API keys separated by commas. Always split and use the first: apiKey.split(',')[0].trim(). The createAuthenticatedSession() helper handles this automatically.
-
WebSocket polyfill — Node.js doesn't have a native WebSocket. Add (globalThis as any).WebSocket = WebSocket (from ws package) before any SDK calls. The createAuthenticatedSession() and initSDK() helpers handle this automatically.
-
Amount units — All amounts are strings in smallest units (lamports, wei). Use formatSolAmount() and formatEthAmount() helpers to convert. For USDC: multiply by 1e6 (not 1^6!) - 5 USDC = 5 * 1e6 = 5,000,000 units.
-
No /v1/health endpoint — Do NOT use /v1/health for connectivity checks; it returns 404. Use GET /v1/status → {"running":true} or sdk.tokens.getNativePrices() as lightweight unauthenticated checks.
Error Handling
Always wrap SDK calls in try-catch blocks:
try {
const result = await buyToken(session, {
tokenAddress: 'TOKEN_ADDRESS',
amount: formatSolAmount(0.005),
});
if (result?.isSuccess) {
console.log('Success:', result.hash);
} else {
console.log('Failed:', result?.message);
}
} catch (error) {
console.error('Error:', error.message);
}

Agent Integration
Connectivity Detection
Agents should verify API reachability before attempting trades. Do NOT call /v1/health (it doesn't exist). Use this pattern:
import { initSDK } from 'gdex-trading';
const sdk = initSDK('https://trade-api.gemach.io/v1', process.env.GDEX_API_KEY);
const prices = await sdk.tokens.getNativePrices();
const isOnline = prices && Object.keys(prices).length > 0;
Required Header Injection
The initSDK() and createAuthenticatedSession() functions automatically inject the required Origin, Referer, and User-Agent headers into the SDK's internal HTTP client. No additional configuration is needed.
For agents that bypass the SDK and make direct HTTP calls:
import { REQUIRED_HEADERS } from 'gdex-trading';
const response = await fetch('https://trade-api.gemach.io/v1/token/native_prices', {
headers: { ...REQUIRED_HEADERS }
});
Offline Fallback
If the API is unreachable (network issues, not header misconfiguration), agents can still:
- Read cached wallet info from
.env
- Generate QR codes for wallet addresses
- Display static skill documentation
- Show deterministic wallet reports
But cannot execute trades, fetch live prices, or authenticate sessions.
Security Notes
- Never log or expose private keys
- Use session keys for trading, not wallet keys
- Validate addresses before transactions
- Test with small amounts first
- Verify chain IDs match intended network
