Protecting a seed phrase is essential, but it is only one layer of wallet security.

A recovery phrase can remain offline and uncompromised while the wallet itself accumulates dangerous permissions. An unlimited token allowance can let a spender move assets later. An NFT operator approval can cover an entire collection. A signed permit can create spending authority even when the user never submits a normal approval transaction directly.

The wallet’s interaction history matters too. Repeated contact with unverified contracts, risky counterparties, unknown bridges or compromised applications can change the wallet’s exposure long after it was created.

Strong custody therefore requires ongoing review. Check active token allowances, NFT operators, delegated authority, smart-account modules and unfamiliar counterparties. Investigate unexpected funding paths and unusual asset movements. Separate the safety of the private key from the safety of the permissions attached to the address.

The practical rule is simple: protecting the backup prevents one class of failure. Reviewing what the wallet can currently authorize helps prevent another.
