🧵 Seed phrases are not a feature. They’re a bug.
Crypto keeps telling people:
“Write this 12-word phrase. Never lose it. Never share it.”
Then blames them when it goes wrong.
That’s not security.
It’s a failure waiting to happen.
ALT Dark blue background with centered bold text. The first line reads: “Seed phrases are not a feature.” The second line, in turquoise green, reads: “They’re a bug.” The Vultisig logo appears in the bottom right corner.

first time I've seen this scam, so posting it as a heads up for users and interfaces
someone bought the ens "[myEthereumAddress].eth"
so when you paste in my address, the top result in some UIs is an ens match instead of the resolved ENS name
impt for UIs to filter these out

1/ SOMEONE JUST LOST $5M in an ERC-20 phishing transaction using so-called increaseAllowance() method.
ERC20 phishing scams netted $50M/m to the bad guys, mostly using permit(), increaseAllowance(), approve().
What are these methods and why do people keep losing money?
