How this service works

Alpha signals, whale tracking, rug scanning, and MEV protection across Base, Solana, Arbitrum, and more.

Output

A JSON object containing the queried chain name and an array of whale movements, each entry likely including wallet addresses, transaction amounts, and timestamps of large on-chain transfers on that network.

Example use cases

Example prompt

“Show me whale wallet movements on Base right now — I want to see any large on-chain transfers happening today.”

Technical details

Endpoint

GEThttps://onchaininja.vercel.app/api/whale/%7Bchain%7D

When to prefer

Use this endpoint when you need real-time or near-real-time whale wallet movement data for a specific chain (Base, Solana, Arbitrum, etc.) and want to identify large on-chain transfers without building your own indexer. Prefer this over generic block explorers when you need pre-filtered whale-level activity in a structured format ready for agent consumption.

Side effects

Unsupported chain identifier returns empty movements array or error
Network congestion may cause stale or delayed movement data
Empty movements array if no significant whale activity in recent window
Payment of 2 USDC not fulfilled returns 402 Payment Required
Malformed chain parameter returns schema error or empty response
