+#### P2PK Derivation
+
+Wallet are able to generate private keys is a deterministic way to have proofs locked to them.
+
+The following BIP32 derivation path for derivation of the key: `m/129372'/10'/0'/0'/{counter}`:
+
+- 129372': Registered SLIP-0044 coin type for Cashu.
+- 10': Purpose for generating private keys for usage in P2PK.
+- {counter}: Incrementing counter encoded as an unsigned 64-bit integer in big-endian format.
+
+This will allow wallets to swap proof that are still locked to a public key during a restore process.
