Build a wallet change log
Make changes understandable to your future self.
Source foundation
Wallet security includes backups, access protection, and recovery planning. Bitcoin: securing your wallet.
A worked example
A fictional owner changes devices in January, updates recovery instructions in March, and tests a small transfer in April. A log containing only dates is hard to interpret. Adding the purpose, non-secret result, and unresolved issue makes the sequence reviewable without exposing signing material.
Original hypothetical example. Amounts, people, events, and scenarios above are invented for learning; they are not historical observations or forecasts.
What to take from it
Record what was verified rather than declaring the whole setup safe.
Try it on paper
Create a blank log with date, change, verification, and follow-up columns.
Keep the assumptions beside your answer. Check the result before applying the idea to a different situation.
