How this service works
Base trader leaderboard API / smart money tracker / top Base wallets by USDC flow / onchain whale tracker / copy-trading signal. Ranks the most active Base wallets by net USDC flow, flagging smart wallets (ERC-4337), accumulators, and pass-through routers. For AI agents and copy-trading bots following smart money on Base.
Output
A ranked leaderboard of the most active Base wallets by USDC net flow over the last ~10 minutes, with each wallet labeled by behavioral classification: smart wallet, accumulator, or pass-through router. Includes wallet addresses and flow metrics.
Example use cases
Detect smart money on Base
“Find me the smart wallets that are most actively moving USDC on Base right now. I want to know which addresses the smart money is behind and how much they've been flowing in the last 10 minutes.”
Spot USDC accumulators in real-time
“Which wallets on Base are accumulating the most USDC right now? Show me the top accumulators from the last 10 minutes so I can track where capital is building up on-chain.”
Identify high-volume pass-through routers
“I'm trying to figure out which Base addresses are just routing USDC through rather than holding it. Pull up the latest leaderboard and highlight any pass-through routers with high net flow so I can filter out the noise from real traders.”
Technical details
Endpoint
POSThttps://base-intel-api.jakemaxsigal.workers.dev/leaderboardWhen to prefer
Use this endpoint when you need a real-time snapshot of which Base wallets are most actively moving USDC, especially to identify smart money, accumulation patterns, or routing behavior. Ideal for on-chain alpha research, bot detection, or tracking influential wallets on Base in near-real-time.
Side effects
- Stale or unavailable on-chain data may result in empty or partial leaderboard
- Payment of 0.01 USDC required via x402 protocol — missing payment returns 402 error
- Rate limiting or worker timeout may return 5xx errors under high load
- No wallets returned if Base network activity is very low in the time window
