How do you avoid Web3 scams?

A valid transaction remains valid even when obtained through deception.

Fraudsters copy a brand, manufacture urgency and steer users toward an irreversible gesture.

The weak point is often not the network or wallet, but the context shown to the user.

One changed letter in a domain is enough to imitate a familiar interface.

Ads, private messages and fake support place the malicious link at the right moment.

The browser lock encrypts the connection; it does not prove the site is legitimate.

Signing a message can connect an account, prove identity or authorise an action.

Signing a transaction can transfer an asset or call a complex contract.

If the wallet cannot make the action readable, refusing is safer than guessing.

An approval lets a contract move certain tokens later without the same new permission.

An unlimited allowance turns a one-off mistake into lasting exposure.

Disconnecting the site does not revoke permission recorded on-chain.

Urgency — an offer or account supposedly expires

Authority — fake support demands a procedure

Reward — an airdrop promises much for one small gesture

Isolation — the fraudster prevents checking another source

Domain — open from a bookmark or official source

Network and contract — confirm expected addresses

Action and amount — read what actually leaves

Test — use a small amount and a separate wallet

Separate savings from the wallet used with applications.

Regularly revoke approvals that are no longer needed.

Never enter a seed after following a link: legitimate support never asks for it.

When in doubt, stop, verify elsewhere and accept missing the opportunity.
