Ethereum's Clear Signing feature is live. It makes transactions human-readable before a user signs, eliminating the blind signing risk that has cost people millions in stolen funds. For years, attackers exploited wallets that only showed a hash — users approved without knowing what they were actually authorizing. That hole is now closed.
The blind signing problem
Blind signing forced users to approve transactions based on an unintelligible hash. Scammers abused this by slipping in malicious contract calls. It wasn't a theoretical risk — real thefts happened repeatedly. The industry called it a design flaw, but fixing it meant changing how wallets and protocols handle signatures.
How Clear Signing works
Instead of a hash, Clear Signing displays the transaction's key details in plain language: the token, the amount, the recipient, and the function being called. The feature sits at the protocol level, meaning any compatible wallet can surface this data without custom integrations. No more guesswork. No more "sign this and hope."
Who benefits most
Everyday users who interact with DeFi dApps or sign approvals are the immediate winners. Power users and developers also get a clearer audit trail. The fix doesn't require users to change behavior — just update their wallet to one that supports the new standard.
What happens now
Wallet providers are expected to roll out support over the coming weeks. Ethereum's core developers have already pushed the necessary reference code. For users, the advice is simple: switch to a Clear Signing–compatible wallet as soon as one you trust adds support. The blind signing era is over — but only if people actually use the new tools.
