Understanding Seed Phrases and Wallet Security

So the seed phrase is not the key, just so you're aware.

Seed phrase is what you use to regenerate a wallet address.

The keys are separate of that, and they are on the blockchain,

and they are exposed when you send or receive things.

In order to keep your wallet quantum-proof and best secured,

you would want to rekey it after any transaction where you send assets out of the wallet.

Sending assets to the wallet is only going to expose one key,

whereas sending assets out of the wallet will then expose the additional key.

And rekeying that sending key is going to be what's best needed

in order to keep it quantum secure.

And again, I would just Google it.
