@susil-mohanty Seems the example code is outdated w/ the pycoin lib.
Let's try this instead

from pycoin.ecdsa.secp256k1 import secp256k1_generator

def sign_ecdsa_secp256k1(msg, priv_key):
    return secp256k1_generator.sign(priv_key, sha3_256(msg))


def verify_ecdsa_secp256k1(msg, sig, pub_key):
    return secp256k1_generator.verify(pub_key, sha3_256(msg), sig)

ImportError: cannot import name 'sign', 'verify'

Same error is coming for sign and verify...
