Vitalik on Transaction Simulation for Crypto Wallet Security
Wallet security used to be about one thing: don’t lose your seed phrase. In 2026, that’s still true—but it’s not the main way people lose money.
Now the most common disasters are “I signed something” moments: a fake approval, a malicious contract interaction, a confusing signature prompt, or a wallet drainer that empties tokens before you even realize what happened.
