TIL ColdCard's libngu code reference is "Number go up"... oh the irony

ColdCard used a python library named "ngu" for "Number go up"
ngu.hash
ngu.secp256k1
ngu.random
ngu.codecs
ngu.hdnode
ngu.hmac

def generate_seed(): # Generate 32 bytes of best-quality high entropy TRNG bytes. seed = ngu.random.bytes(32) assert len(set(seed)) > 4 # TRNG failure # hash to mitigate any possible bias in TRNG return ngu.hash.sha256d(seed) 

The funny and sad irony is that all of these users actually saw "Number go zero"...

They (ColdCard/CoinKite) need to go belly up and liquidate all of their holdings... and distribute them back to victims.
