Frequently asked questions
Does a clean result guarantee access to the wallet funds?
No. The checker helps you catch structural mistakes, but the final wallet software, derivation path, and phrase history still determine whether recovery succeeds. Always verify critical recovery data with your own wallet workflow.
Should I paste a real production seed phrase here?
Use the page carefully and prefer test phrases whenever you can. If you must review sensitive data, confirm the page trust badges and keep your own security policy in mind before you paste recovery material anywhere.
