Trezor enabled Clear Signing on September 8, allowing users of supported hardware wallets to review smart contract actions, token amounts and destinations in readable form rather than approving opaque hexadecimal transaction data. Trezor and the Ethereum Foundation confirmed the ERC-7730 integration on X. The feature works automatically through Trezor Suite, WalletConnect and Trezor Connect on the Safe 7, Safe 5, Safe 3 and Model T; the Model One is not supported. Initial protocol coverage includes 1inch, Aave, Lido, Tether, LiFi and Hyperliquid. ERC-7730, formalized by Ledger in 2024 and now governed by the Ethereum Foundation, uses off-chain descriptors and an attestation layer to help wallets interpret contract calls without requiring contract redeployment. The rollout targets blind signing, an information gap the Foundation has associated with major crypto thefts, including the $1.5 billion Bybit breach it cited as the largest crypto hack on record. Protection depends on protocols supplying descriptors to the clearsigning.org registry, which grew roughly 28% between May 2026 and the end of July 2026.
