How this service works
Base whale-transfer intelligence from live ERC-20 logs, enriched with USD pricing.
Output
A list of recent large ERC-20 token transfers on Base chain, each enriched with USD pricing, including sender/receiver wallet addresses, token amounts, and transfer metadata extracted from live on-chain logs.
Example use cases
Track whale exits before crash
“Check the last 300 blocks on Base for any large USDC or USDT transfers — I want to know if big wallets are quietly moving funds out before a potential sell-off.”
Monitor rival token whale moves
“Scan Base chain for the biggest ERC-20 transfers involving this token contract in the past 200 blocks and tell me which wallets are accumulating or dumping, with USD values.”
Spot unusual large transfer activity
“Pull the most recent whale-level token transfers on Base from live on-chain logs — flag anything over $500K USD and show me the sender, receiver, and exact amounts so I can investigate suspicious wallet behavior.”
Technical details
Endpoint
GEThttps://walletwatch.deleonanalytics.com/whales?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, USD-enriched whale transfer data specifically on the Base chain from live ERC-20 event logs. Prefer this over generic block explorers when you need structured, pre-enriched output with USD values and configurable scan depth.
Side effects
- Invalid token contract address returns empty results or error
- Requested block depth exceeds available history or node range
- Limit parameter too high may result in slow response or timeout
- No whale transfers found in the specified block range returns empty array
- Network congestion on Base may delay log scanning
