How this service works
Who is moving size on Base right now: large ERC-20 transfers reported as observed facts with amounts and source, not as trade signals or predictions.
Output
Returns an array of whale signal objects representing observed large ERC-20 transfers on the Base network, with a SUCCESS status indicator. Each signal likely includes details such as token address, transfer amounts, sender/receiver addresses, and timestamps of the detected large transfers.
Example use cases

Technical details
Endpoint
GEThttps://api.m2msentinel.com/v1/whales/signalsWhen to prefer
Choose this endpoint when you need real-time or near-real-time observations of large ERC-20 token transfers specifically on the Base blockchain. It is purpose-built for whale signal detection on Base, making it superior to generic blockchain explorers or multi-chain analytics APIs when Base-specific whale activity is the focus. Prefer this over DEX volume or price feeds when the primary concern is large wallet movements rather than market liquidity or pricing.
