Summary of gRPC methods

Full details available here.

• ValidateAddress ➔ check whether an address is valid for the given chain parameters.

• DeriveExtendedKey ➔ derive a child extended key based on BIP0032 derivation rules.

• EncodeAddress ➔ serialize public key into a network-specific address.

• GetAccountExtendedKey ➔ serialize public key-material into xPub.

• CreateTransaction ➔ prepare a raw TX based on TX params.

• SignTransaction ➔ combine a raw TX with DER signatures to produce the signed TX.

• GetKeypair ➔ derive an extended public-private keypair from a seed on a given derivation.

  ⚠️ Note: for use in tests only.

• GenerateDerSignatures ➔ sign a raw TX with a private key to produce DER signatures.

  ⚠️ Note: for use in tests only.
