Put account access, networks and permissions into one simple review.
LET’S PICTURE IT
Imagine a visitor asks to see your club membership card, then hands you a separate authorization form. Treat those as different requests.
SEE IT FOR YOURSELF
From a public address to a verified signatureStep 1 / 4
An address is public receiving information. It is not the private key that authorizes actions.
An address is public receiving information. It is not the private key that authorizes actions.The local signing system uses secret authorization material. It produces a signature; the private key is not sent along with it.A verifier checks the signed request under the account’s rules. A valid signature does not by itself prove that the action is safe.Balances belong to network state. A wallet is an interface and signing system, not a box containing coins.

Scenario one: an account appears
A website asks you to connect an account. That can reveal a public address and network context. It is not the same as signing the site’s next transaction, and public account exposure can still affect privacy.
Scenario two: a tiny value, a large allowance
The site displays a small intended purchase but asks for a much larger approval. Read the spender and allowance rather than judging the request only by the visible payment. Closing the tab afterward does not erase an onchain approval.
Scenario three: a missing balance
After changing networks, your balance display changes. First check chain, account and asset identity. Switching a network is not a bridge, and an address shared across chains does not create a shared balance.
Scenario four: a helpful stranger
Someone claiming to be support asks for a phrase to “refresh” the account. Do not provide it. A public receiving address is enough for many diagnostic conversations; secret key material gives authorization, not just information.
QUICK CHECK · NO PRESSURE
Which action revokes an ERC-20 allowance by itself?
The allowance is contract state. Changing it requires the appropriate authorized action.
