Smart Money Wallet Tracker

Automatically discover and monitor whale wallets across Ethereum, Base, Arbitrum, BSC, and Solana. Find wallets that buy tokens before they pump, track their current positions, and get structured market insights — no API key required.

What It Does

Most whale trackers require you to already know which wallets to watch. This Actor goes further:

1. Discover — Automatically finds wallets that bought top-gaining tokens before they pumped. Ranks them by "hit rate" using a persistent scoring database.
2. Monitor — Scans tracked wallets for large transactions, aggregates token flow, and detects coordinated buying signals.
3. PnL Analysis — Calculates realized PnL, unrealized PnL, and win rate per wallet using FIFO trade matching — similar to GMGN but using direct blockchain data, not a scraper.
4. Insights — Outputs structured signals: which tokens smart money is accumulating, how many wallets are piling in simultaneously, and net inflow/outflow by token.

Modes

Recommended schedule:

• Daily: mode: "discover" — refresh smart money rankings
• Hourly: mode: "monitor" — get fresh transaction data and signals

Input

Example: Fully automated (no wallet list needed)

{
"mode":"both",
"chains":["ethereum"],
"minTxValueUsd":50000,
"lookbackHours":24,
"maxDiscoveredWallets":20
}

Example: Monitor specific wallets

{
"mode":"monitor",
"wallets":[
"0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
"0x47ac0Fb4F2D84898e4D9E7b4DaB3C24507a6D503"
],
"chains":["ethereum","base"],
"minTxValueUsd":100000
}

Pricing

Pay-Per-Event (PPE):

• $0.02 per wallet scanned
• No charge for discover-only runs
• Apify platform usage included

Example: Monitoring 20 auto-discovered wallets on Ethereum hourly = $0.40/hour = ~$9.60/day

How the Discovery Works

1. Fetches the top 20 tokens by 24h price gain (>20%) from CoinGecko
2. For each token, scans Ethereum transfer history 72 hours before the pump
3. Identifies wallets that made repeated purchases (not DEX routers or burn addresses)
4. Scores each wallet: score = hits × log(1 + hits) — rewards consistency
5. Results persist in a named Apify KV Store across runs, so the ranking improves over time

Running discover daily for a week gives you a high-confidence smart money list with proven prediction history.
