GMGN Smart Money Buy Signals — Live Whale, KOL & Smart-Wallet Crypto Buy Feed

Watch the smartest crypto wallets in real time. This actor scrapes GMGN.ai's smart-money cards (tokens where verified smart wallets are buying) and the live smart-money trade stream across all six chains GMGN supports — Solana, BSC, Ethereum, Base, Tron, Monad.

The fastest copy-trade / alpha-feed input on Apify. Per run: up to 100 tokens × 5-20 wallets each = 500-2,000 buy-signal records, refreshed continuously.

🚀 What this actor does

Smart money on-chain is real money. GMGN tags wallets that consistently make profit, follow KOLs, or carry verified Twitter / fund profiles. When those wallets are concentrated on a single token, it's a high-conviction signal.

This actor pulls two complementary GMGN feeds:

1. Smart-money cards (/api/v1/smartmoney_cards/cards/{chain}/24h) — per token: the token's full security audit, market cap / liquidity / swaps / holders, AND a list of smart wallets that bought in the last 24 hours (each wallet with tags, net inflow, buy/sell counts, side, timestamps).
2. Live trade feed (/api/v1/smartmoney_cards/trades/{chain}) — every individual smart-money trade as it happens, with token info, USD amount, price, side, transaction hash, and maker (wallet) info.

You pick which mode (cards, trades, or both) and which chains. With explodeWallets: true the cards mode emits one row per (token × wallet) — the most actionable format for copy-trade bots.

---

💡 Use cases

• Copy-trade bots — auto-buy when ≥ 3 smart wallets accumulate a token in the last hour.
• Discord / Telegram alpha bots — auto-post "👀 Smart money buying X" when a card has ≥ N wallets.
• Alpha-feed Substack / X newsletter — daily roundup of smart-money picks across chains.
• AI signal training — collect labelled smart-money trades over months to train classifiers.
• Whale watching dashboard — power your own SaaS with the live smart-money trade stream.
• Anti-frontrun detector — track fresh-wallet smart trades; correlate with subsequent KOL tweets.
• Compliance / forensics — audit which "smart" wallets are buying questionable tokens.
• Memecoin sniper backtest — backfill historical smart-money cards into ML training data.

{
  "chains": ["sol","bsc","eth","base","tron","monad"],
  "mode": "cards",
  "explodeWallets": true,
  "tagFilter": ["smart_degen"]

🛡️ Under the hood

• Endpoints — GET /api/v1/smartmoney_cards/cards/{chain}/24h, GET /api/v1/smartmoney_cards/trades/{chain}?limit=100.
• Auth — none (Cloudflare-fronted, fingerprint-gated).
• Proxy — Apify Residential default. Datacenter works but with higher rate-limit risk for this endpoint.
• Retries — 5 attempts with exponential backoff on 403 / 429 / 5xx.
• Decompression — Brotli auto-handled.

❓ FAQ

What's the difference between "cards" and "trades"?

Cards = per-token aggregation ("which tokens are smart wallets buying?"). Trades = atomic events ("here are the last 100 smart-money trades"). Use cards for token-level alerts, trades for trade-by-trade telemetry.

What does isOpenOrClose: 1 mean?

The wallet opened a NEW position with this trade (1) vs closed/reduced an existing one (0). When sniping copy-trades, only 1 is interesting.

How fresh is the data?

The 24h cards refresh every ~30 seconds. Trades refresh every block. Actor pulls whatever's current at call time.

Why are some cards showing only 1 wallet?

GMGN's algorithm surfaces tokens where AT LEAST one tagged smart wallet bought in 24h — single-wallet cards are common. Use minSmartWallets: 3 to filter to multi-wallet conviction.

Can I filter by wallet ENS / nickname?

Not server-side, but the walletEns and walletName fields are exposed — filter client-side.

Does the actor catch sells too?

Yes — the trades feed includes both buys and sells. Set onlyNewBuys: false to keep position closes.

What's walletNetInflow (negative)?

Negative net inflow means the wallet has net-bought (more outflow of quote = SOL/BNB → more inflow of token). It's how GMGN tracks USD-equivalent position direction.

Can I follow a specific wallet over time?

Not directly through this actor — use GMGN Wallet Portfolio & PnL Tracker for wallet-centric scraping.

What's tradeBalance?

The wallet's balance of the token after the trade. Useful to spot full exits (tradeBalance == 0 and tradeSide == "sell").

How do I correlate buys with Twitter / TG chatter?

Combine this actor's output with GMGN Crypto KOL Twitter & Telegram Signal Feed — join on address to see which tokens have both smart-money buys AND KOL mentions.
