Alternatives / Arkham
Arkham alerts alternative — ChainSonar
ChainSonar is for traders who want clean Ethereum exchange flow alerts — real deposits and withdrawals from known exchange and whale wallets, without the noise of an exchange moving funds between its own addresses.
The difference: internal transfers filtered
ChainSonar tracks known exchange wallets (Binance, Coinbase, Kraken, Bitfinex, Upbit, Robinhood) and known whale wallets on Ethereum. It marks exchange-internal transfers — an exchange moving funds between its own wallets — and hides them by default, so alerts show real deposits and withdrawals. You get real-time alerts by Telegram plus a live web dashboard, choose your own USD minimum and which wallets to follow, and start with a 14-day free trial (no card needed). Read-only: ChainSonar never asks for wallet keys and never holds funds.
Example
$248M USDC into Coinbase 10 looked huge — it was Coinbase moving funds between its own wallets. ChainSonar marks this as internal and hides it. A real $109M USDC move the same week was shown.
