Private key handling outside of BIP44 or BIP32 derivation

[shuse2]

Hello,
I have question regarding handling the private key.

I have different derivation protocol than BIP44 or BIP32 need to support.
To be precise, sign.keyPair.fromSeed(hash(recovery phrase)) using ed25519.

Is it possible to access the imported root private key from snap?
Otherwise, only option I see is that importing recovery passphrase or private key from UI to snap directly through wallet_invokeSnap.

Security wise is it allowed or safe to communicate the private key or secret passphrase between dapp and snap? (Only once when importing)

Hi @shuse2, thanks for reaching out. Could you tell me which protocol you are trying to support with this derivation?

Im trying to integrate Lisk using the snap.
The derivation is specific to the legacy protocol on the previous version that I want to support
