What Is “Blind” Signing and Why Is It Dangerous?
Within the Ethereum ecosystem, users frequently interact with decentralized applications (DeFi), swap tokens, and connect wallets to various services. To confirm these operations, users must sign transactions through crypto wallets such as MetaMask, Ledger, or Trezor. Until recently, however, most transaction requests were displayed as complex technical data that ordinary users could neither verify nor fully understand. Instead of seeing a clear explanation like “swap 1,000 USDC for 0.42 ETH via Uniswap,” users were presented with strings of symbols and code. As a result, many people approved transactions without understanding what permissions they were granting or what actions would be performed with their assets. Scammers actively exploit this weakness: victims can be tricked into signing transactions that grant access to their tokens or transfer cryptocurrency to another address. These confirmations are often the final stage of phishing attacks and crypto theft.
The New Clear Signing Standard: Transparency and Protection
On May 12, 2025, the Ethereum Foundation introduced the open Clear Signing standard, intended to eliminate “blind” signing. Instead of raw code, users will now see a human-readable description of the operation they are about to approve. For example, instead of a long string of hexadecimal data, the wallet may display messages such as “grant permission to spend all tokens” or “transfer 10 ETH to address X.” This allows users to consciously approve or reject transactions. The system is built around the ERC-7730 standard and a separate open registry containing transaction descriptions that can be reviewed by independent auditors and security researchers. Major industry players participated in the initiative, including Ledger, Trezor, MetaMask, WalletConnect, Fireblocks, and other companies within the Ethereum ecosystem.
How Scammers Operate and Why Clear Signing Is a Breakthrough
“Blind signing” scams typically rely on so-called drainers—malicious smart contracts designed to steal crypto assets from wallets. If a victim connects a wallet to a drainer website and blindly signs a transaction, all accessible assets in that wallet can be drained automatically. In 2024, operators of one of the most popular drainer services announced they were shutting down after the software was reportedly used to steal $85 million from more than 21,000 victims. In most cases, drainers are embedded into fake copies of legitimate crypto project websites or phishing pages promising token or NFT airdrops. If Ethereum’s new solution gains widespread adoption, users will receive a clear warning during the signing process indicating that the transaction would transfer all available tokens to another wallet.
Why This Matters for the Entire Industry
The problem of “blind” signing is not only technical but also social. According to various studies, more than 60% of cryptocurrency users do not fully understand what they are signing when interacting with DeFi applications. This leads to massive financial losses and undermines trust in decentralized finance as a whole. The introduction of Clear Signing is a major step toward mainstream cryptocurrency adoption. When operations become transparent and easy to understand, the barrier to entry for new users decreases while overall security improves. In addition, the initiative encourages the development of smart contract auditing and promotes higher transparency standards across the industry.
Interesting Facts and Developments
Between 2023 and 2024, losses from phishing attacks and malicious smart contracts on Ethereum exceeded $1 billion. Major crypto wallets have already announced support for the new standard: MetaMask plans to integrate Clear Signing in upcoming updates, while Ledger and Trezor are expected to release firmware updates supporting ERC-7730 before the end of 2025. Interest in cryptocurrencies continues to grow in Russia: according to surveys, more than 15% of Russians own digital assets, and security remains their top concern.
Conclusion
The implementation of the Clear Signing standard is more than just a technical upgrade—it represents an important milestone in the evolution of the cryptocurrency industry. Transparent operations, understandable transaction descriptions, and independent auditing make the Ethereum ecosystem more secure and user-friendly. As a result, users will be able to manage their digital assets with greater confidence and awareness, while scammers will find it far more difficult to deceive unsuspecting cryptocurrency holders.
