How this service works
Track large wallet movements (whales) with on-chain transaction monitoring
Output
Returns an array of recent whale transactions matching the specified chains, minimum USD value, and token filters, including details about each large on-chain movement detected.
Example use cases
Alert on million-dollar Bitcoin moves
“Let me know whenever there are Bitcoin transactions over $1 million on-chain — I want to stay ahead of any big whale activity that could signal a market move.”
Monitor DeFi whale activity in real time
“Keep an eye on large wallet movements in DeFi tokens on Ethereum and Solana, anything above $250,000, so I can spot when whales are rotating into or out of major DeFi protocols.”
Track USDC transfers across blockchains
“Find all recent large USDC transfers across Ethereum, BNB Chain, and Solana above $500,000 — I need to see if any big players are moving stablecoins right now.”
Technical details
Endpoint
POSThttps://coinrailz.com/x402/service/whale-alertsWhen to prefer
Use this endpoint when you need real-time on-chain surveillance of large wallet movements across one or more blockchains, optionally filtered by minimum USD value or specific token contracts. Prefer this over general market data endpoints when you care specifically about individual large transactions rather than aggregate price or volume data.
Side effects
- Invalid chain identifiers return error or empty results
- Extremely low minValueUsd thresholds may return very large result sets
- Invalid token contract addresses may return no results
- Payment failure via x402 protocol blocks the request
- Temporary blockchain node unavailability may cause stale or missing data
