Ethereum Foundation Launches Clear Signing Standard to Combat Wallet Drains
The Ethereum Foundation unveiled a new Clear Signing standard on May 12, designed to stop users from approving malicious cryptocurrency transactions they cannot read or understand. The initiative targets the widespread practice of blind signing, in which wallets display raw hexadecimal data instead of plain-language transaction details.
The proposal follows billions of dollars in cumulative losses from phishing attacks and wallet drains across the Ethereum ecosystem.
What the Clear Signing Standard Does
The standard, surfaced by CoinDesk, requires wallets and decentralized applications to display human-readable transaction details before a user signs. Blind signing, the alternative, forces users to approve opaque data strings with no clear indication of what funds are moving or to which address.
Ethereum (ETH) developers have long identified blind signing as the primary entry point for phishing exploits.
Attackers craft malicious approval transactions that drain entire wallets after a single user confirmation. The Clear Signing standard aims to close that gap by making every approval legible before it is finalized.
The Foundation did not publish an exact implementation timeline in its May 12 announcement.
Adoption will depend on wallet providers and dApp developers choosing to integrate the standard into their interfaces.
Background
Phishing attacks targeting Ethereum wallets escalated sharply between 2022 and 2025, with several high-profile drains exceeding $10 million each. Approval-based exploits, in which attackers trick users into signing token allowances that grant full access to a wallet’s holdings, became the dominant attack vector.
Security researchers at firms including Blockaid and Wallet Guard catalogued thousands of malicious approval contracts deployed across the Ethereum mainnet during that period.
The Ethereum Foundation has pursued multiple security tracks in parallel. Its prior work on account abstraction, formalized through ERC-4337, laid groundwork for programmable wallet logic that can reject suspicious transactions at the protocol level.
Clear Signing represents a complementary layer targeting the human-readable interface rather than the underlying execution logic.

What Comes Next
Wallet providers including MetaMask, Ledger, and Rabby have each introduced partial transaction-decoding features in recent product cycles. Whether those teams adopt the Foundation’s standard as a unified specification, or continue building proprietary decoders, will determine how quickly users benefit from the change.
The Ethereum ecosystem processes hundreds of billions of dollars in monthly transaction volume.
Even incremental reductions in successful phishing attacks represent meaningful protection at that scale. Observers will watch whether the Clear Signing standard advances toward a formal EIP, which would formalize its requirements for all compliant wallets.
