Ledger has rolled out smart contract proxy support for its clear signing process, giving hardware wallet users stronger protection against stealthy exploits that target upgradeable contracts. The update tackles a growing threat in the Ethereum ecosystem where attackers manipulate proxy logic without altering the visible contract address.

Proxy contracts are widely used by developers because they separate a contract’s fixed address from its executable code.

A lightweight proxy holds the address users interact with, while pointing to a separate logic contract that contains the actual functionality.

This design makes upgrades easier and cheaper, as only the logic contract needs redeployment.

However, the same mechanism creates…
