EIP-7702 is the greatest marketing disaster in Ethereum history...
- no mainstream (or any that I know of) wallet implements a flow for signing an arbitrary delegation
- attackers use EIP-7702 once they have the user's private key, to make draining easier
- user sees EIP-7702 on chain and immediately thinks "I got phished into signing a delegation", not "my private key is compromised"
For anyone in this situation who doesn't believe me, just send funds to your compromised address on a DIFFERENT chain. You will see a NEW delegation appear, without your involvement, and your funds get drained.
