Which of these did you sign? 👇

example of a token approval transaction

Token Approval

What to do

- Go to Revoke.cash
- Revoke approvals for any tokens you signed for
- Especially if the allowance is to an address like 0x… rather than “Opensea”

example of a seaport signature

Seaport Signature

What to do

Invalidate previous Seaport Signatures

Option 1
- Go to the Seaport contract on Etherscan
- Click Connect to Web3
- Click "Write" under "incrementCounter" and sign

Option 2
- Visit Harpoon
- Click and sign Button 1 which does the same as above

example of a dangerous eth_sign transaction

Generic signature (eth_sign)

What to do

This signature can do almost anything to your wallet, so
- Create a new wallet and transfer your assets there

Otherwise do all the above steps

example of a fake/scam "upgrade to" transaction

"Upgrade to"

What to do

- Go to Revoke.cash
- Revoke approvals to OpenSea (old) for tokens that you care about

example of a dangerous 'security update' web3 transaction

"Security Update"

What to do

This scam usually takes your ETH immediately
Unfortunately there's nothing you can do here to get that ETH back 😞

I don't remember what I signed!

Create a new wallet (with a new seedphrase)
Move everything to that new wallet

I didn't sign a transaction or signature!

You might have a compromised seedphrase.
This usually happens through being tricked (e.g. fake Metamask support) or downloading malware (e.g. fake P2E game).

What to do
- Create a new wallet with a new seedphrase.
- Move your assets to that new wallet ASAP.
If you suspect it's malware, do these two steps with a different, safe device. Or remove the malware first with Malwarebytes or other programs.
