The Ethereum Foundation and an Ethereum Working Group launched Clear Signing on May 12 — an open standard designed to turn opaque Ethereum transaction approvals into human-readable fields. The move directly targets blind signing, the practice of approving transactions without seeing the full intent in readable form, which has been linked to billions in user losses including the Bybit hack. Separately, ERA Wallet introduced ERA Lens, an on-device engine that parses raw calldata into plain language before signing.
Why blind signing is a structural flaw
Blind signing isn't a niche bug — it's a structural flaw. Hardware wallets protect private keys but don't solve the core problem: users still approve transactions they can't read. The Bybit hack demonstrated that even when private keys remain secure, a malicious approval can still drain assets. The attacker tricked the signer into approving a transaction that looked legitimate on a hardware wallet screen but actually handed over control of funds. Clear Signing aims to eliminate that gap by converting transaction data into readable fields such as function, amount, recipient, token, and protocol.
How Clear Signing works
The standard transforms raw calldata into structured, human-readable fields before the user signs. But coverage depends on support from wallets, dApps, metadata providers, and the broader ecosystem. It's not a magic switch — it's an infrastructure play. The Ethereum Working Group is pushing for adoption, but the standard only helps when the entire transaction chain participates. Screenless hardware devices still need to verify transactions on a connected device, which remains exposed to phishing or malware.
ERA Lens takes a different route
ERA Wallet's ERA Lens approaches the same problem from the device side. Instead of relying on external metadata, ERA Lens runs an on-device transaction parsing engine that converts raw calldata into plain-language details before signing. That means the parsing happens locally, not on a connected phone or PC. It's a direct answer to the screenless hardware wallet vulnerability — though it only works inside ERA Wallet's own ecosystem for now.
Neither Clear Signing nor ERA Lens solves blind signing overnight. Clear Signing needs wallet and dApp adoption; ERA Lens needs broader device support. The Ethereum Foundation hasn't announced a specific deadline for mandatory Clear Signing compliance, and wallet makers are still evaluating the standard. For users, the practical takeaway is the same as before: don't sign what you can't read. But for the first time, there's an open standard trying to make that possible.
