Core security principles
Outdated operating systems and browsers increase exposure to known vulnerabilities, so wallet devices should maintain reasonable patching and screen-lock practices. When working with Device Security, separate what the interface displays from facts that can be verified on-chain. A wallet can organize information and prepare requests, but the network, address, contract, and final transaction state still need independent context. If a critical field cannot be explained, stop before confirming and verify it again instead of responding to urgency from a page, an unknown contact, or short-term market movement.
Public computers, shared devices, and untrusted public Wi-Fi are poor environments for handling seed phrases, private keys, or high-value signing requests. In a real workflow, Device Security should not be reduced to a single click or one status message. Review the network, account, requested action, amount, and permission scope as separate checkpoints so inconsistencies become visible earlier. If a critical field cannot be explained, stop before confirming and verify it again instead of responding to urgency from a page, an unknown contact, or short-term market movement.
Key fields
- Confirm that the network, address, or contract involved in Device Security matches the intended context
- Use public information for verification and never submit a seed phrase, private key, or verification code
- Treat signatures, approvals, transfers, and contract calls as separate decisions rather than permanent trust

Remote-control software, screen sharing, and clipboard tools can expand exposure of sensitive information, so confirm the environment is under your control before wallet operations. Risk often hides inside familiar-looking details. Similar names, addresses, domains, and repeated confirmation dialogs can make a request feel routine even when the underlying target or authority is different. If a critical field cannot be explained, stop before confirming and verify it again instead of responding to urgency from a page, an unknown contact, or short-term market movement.
Order of operations
- Confirm that the network, address, or contract involved in Device Security matches the intended context
- Use public information for verification and never submit a seed phrase, private key, or verification code
- Treat signatures, approvals, transfers, and contract calls as separate decisions rather than permanent trust

Outdated operating systems and browsers increase exposure to known vulnerabilities, so wallet devices should maintain reasonable patching and screen-lock practices. After a Device Security action, review the final state and retain non-secret reference information such as the transaction hash, network name, or contract address when relevant so later verification is possible. If a critical field cannot be explained, stop before confirming and verify it again instead of responding to urgency from a page, an unknown contact, or short-term market movement.
