Stablecoin Whale MonitorDocumentation
Everything you need to use the monitor, call the API and understand how the system works.
What it does
Stablecoin Whale Monitor is a public, read-only record of large USDC and USDT transfers on Ethereum mainnet. It watches only transfers of 100,000 tokens or more, waits for 6 confirmations before recording them, keeps 7 days of history, and links every record to Etherscan so you can check it against the chain.
It serves three kinds of reader:
- Analysts researching large movements, mints and burns.
- Treasury and operations teams following an address and sharing the same view with colleagues.
- Developers reading the same records from a small JSON API.
There is no sign-in and no wallet connection.
