Ethereum Just Made It Harder for Hackers to Steal Your Crypto — Here’s How

TLDR

• The Ethereum Foundation and major wallet developers launched “Clear Signing,” a new security standard to make crypto transactions human-readable before users approve them.
• It replaces confusing code with plain-language descriptions of what assets are moving, who receives them, and what permissions are granted.
• The standard is built on ERC-7730 and includes a public registry where transaction descriptions can be verified by independent security researchers.
• Wallets including Ledger, Trezor, and MetaMask are among the earliest adopters. Trezor aims to implement it before June 30.
• The move follows billions in losses from blind signing exploits, including the $1.4 billion Bybit hack.

When a crypto user approves a transaction, they often see a wall of unreadable code. Most people click approve anyway. That gap between understanding and action has cost the industry billions of dollars.

The Ethereum Foundation wants to fix that.

On May 12, 2026, the foundation and a group of major wallet developers announced “Clear Signing,” a new security standard designed to make transaction approvals readable for everyday users.

The idea is straightforward. Instead of displaying raw technical data, wallets would show plain-language prompts — what assets are moving, who is receiving them, and what permissions are being granted.

The foundation called blind signing a “structural flaw” in how crypto transactions currently work. It pointed to the $1.4 billion Bybit hack as a direct example of how attackers exploit this weakness by manipulating transaction signatures that users cannot read or understand.

North Korean state-backed hackers alone have stolen over $7 billion in crypto since 2009. Many of those thefts relied on tricking users into signing transactions they did not understand.

How Clear Signing Works

The standard is built on a proposed Ethereum improvement called ERC-7730, which was originally initiated by Ledger. It also includes a public registry where transaction descriptions can be submitted and reviewed by independent security researchers.

Wallet providers can then choose which trusted sources to pull from when displaying information to users. An attestation framework is also included, allowing auditors to verify that the descriptions shown are accurate.

The Ethereum Foundation’s Trillion Dollar Security Initiative said it will oversee the registry infrastructure and push for wider adoption across the ecosystem.

Who Is On Board

Ledger, Trezor, MetaMask, Keycard, WalletConnect, Argot, Sourcify, Zama, ZKnox, and Fireblocks are among the first platforms to adopt and contribute to the standard.

Trezor’s chief technology officer, Tomáš Sušánka, said attackers have been exploiting blind signing because no widely accessible tool existed to tell the difference between a legitimate transaction and a malicious one.

The feature is being described as a “What You See Is What You Sign” approach to transaction security.

The Ethereum Foundation said approving a transaction is meant to be the last line of defense for users. When done blindly, that defense fails.

Clear Signing does not require changes to the Ethereum blockchain itself. It is a framework that wallets and developers can choose to adopt, making rollout relatively straightforward for participating platforms.

The standard is open-source and publicly available for review.
