ErrBadChecksum describes an error in which the checksum encoded with a serialized extended key does not match the calculated value.

ErrDeriveBeyondMaxDepth describes an error in which the caller has attempted to derive more than 255 keys from a root key.

ErrDeriveHardFromPublic describes an error in which the caller attempted to derive a hardened extended key from a public key.

ErrInvalidChild describes an error in which the child at a specific index is invalid due to the derived key falling outside of the valid range for secp256k1 private keys.

ErrInvalidKeyLen describes an error in which the provided serialized key is not the expected length.

ErrInvalidSeedLen describes an error in which the provided seed or seed length is not in the allowed range.

ErrNotPrivExtKey describes an error in which the caller attempted to extract a private key from a public extended key.

ErrUnusableSeed describes an error in which the provided seed is not usable due to the derived key falling outside of the valid range for secp256k1 private keys.
