A hardware wallet can keep private keys off the computer and still leave a user with an unclear DeFi signing request.

Ethereum DeFi adds approvals, permits, swaps, staking actions, bridge calls and typed-data signatures. The practical comparison is therefore not only which device stores keys securely. It is which setup lets the user verify the intended action on the trusted display.

Clear signing is conditional. Human-readable prompts depend on supported metadata, firmware, companion software and the transaction path. If an interaction is not recognized, the device may show raw fields or require blind signing.

Test the real workflow before moving meaningful funds:

• Use a disposable wallet with a negligible amount

• Try the wallet software and connection path you intend to use

• Test a swap, permit or token approval

• Confirm token, spender, allowance, destination and value

• Record which fields are clear and which remain opaque

• Confirm that recovery restores the expected address path

Browser simulation and hardware verification should be treated as separate security layers. Compare the decoded browser view with the final device display. If critical details disagree, do not sign.

Compatibility can also differ between browser-extension and mobile workflows. Verify the exact software, operating system, connection method and chain path instead of relying on a generic compatibility badge.
