Wallet hygiene is to wallets what password hygiene used to be to web accounts: a set of small, repeated practices that compound into safety over time.
The basics:
- Separate wallets by role. Treasury, operations, dApp interaction, and personal funds should never be the same address. A drain on the dApp-interaction wallet should not touch treasury.
- Review every approval. Hardware-wallet displays are the source of truth, not the dApp UI.
- Revoke approvals you don't need. Use Revoke.cash or equivalent monthly.
- Simulate before signing. Tap-into-Tally, Pocket Universe, or built-in wallet simulation will tell you what a transaction actually does.
- Cold storage for what you don't move. If you haven't transferred from an address in 30 days, it should be on a hardware wallet, not a hot wallet.
- Disposable burner addresses for new dApps. A burner with $50 in it is the right wallet to test a new mint.
