Your wallet just gave away unlimited spending rights
A contract created two days ago can now spend all of your USDC — $6,020 today, and anything you add later. If that wasn't you, cancel it now.
This is a real alert, word for word. No dashboards to interpret.
All quiet.
Four wallets, down 2.1% with the market. No new permissions, no lookalike addresses, nothing that needs you. We checked 4,104 times.
Four ways a quiet wallet loses money.
Old permissions
Years ago you allowed a site to spend tokens from your wallet — a standing permission that never expires. It is the most common way wallets get drained. We find every one still open and tell you which to cancel.
Lookalike addresses
Attackers plant addresses in your history that match the first and last characters of your real contacts — the only characters your eye checks. This trick stole over $83M last year.
Money leaving
A large outflow, a new contract touching your balance, a drop that doesn't match the market. We read the chain around the clock and write the moment something moves.
Every chain at once
Bitcoin, Ethereum, Base, Arbitrum and Polygon in one report. Your wallet app only sees itself — a watchman has to see everything.
Three steps, and one of them is waiting.
Paste an address
A public address, nothing else. It can receive money; it can never send it. No install, no account, no seed phrase.
Read the report
Plain sentences, not a dashboard: what is open, what is odd, what is fine, and what to do about each one.
Let it keep watching
Add it to your watch and we check continuously. You hear from us when something happens — and once a week when nothing does.
Pay once, for a period you choose. Nothing renews itself.
In USDC, from your own wallet. We never hold a card, never charge you again without being asked, and never sell what we see.

Built to be distrusted.
You should be suspicious of crypto sites. So: Canary reads only public blockchain data — the same data anyone can see. A public address can receive money; it can never send it. We never ask for keys or seed phrases, we run no ads, and our scanning rules are published. Read exactly what we check and what we can't see.
Can Canary move my money?
No. We only ever read public blockchain data — the same rows anyone can read. We never ask for a private key or a seed phrase, and there is no place in the product to enter one.
Does the subscription renew itself?
Never. When a period ends it simply stops. We remind you a week before and again the day before, and you decide whether to buy another.
How do I pay?
In USDC, from your own wallet, on Base, Arbitrum, Polygon or Ethereum. No card, no processor, and nothing stored — we read your transaction from the chain and turn the watch on.
What do you know about me?
A username and a password. No email is required to sign up. Addresses you watch are stored encrypted, and alerts go wherever you choose — Telegram, email, or both.
