ERC-7730 now has a cross-wallet network effect: one protocol descriptor can render on Trezor and Ledger, while the Ethereum Foundation stewards a registry any wallet can mirror. Descriptor review joins the security boundary because [ERC-7730](https://eips.ethereum.org/EIPS/eip-7730#registry-poisoning) says registry poisoning must be assumed. Trezor names 1inch, Aave, Lido, Tether, LiFi and Hyperliquid at launch; every unsupported contract drops straight back to blind signing.
