Crypto Payment Security Checklist Released by NOWPayments and BlockSec
A free checklist for crypto payment security and technical compliance has been released by NOWPayments and BlockSec. The guide, available on Chainwire, covers 25 controls across nine areas to help businesses protect themselves from key compromise, suspicious transactions, account takeover, or a stablecoin freeze.
The checklist is designed for daily use and can be applied before starting crypto payments, during vendor reviews, or as part of regular control assessments. It includes items such as verifying private key security, smart contract security, transaction verification, and on-chain monitoring.
'The most common mistake is to treat a crypto payment like a normal online payment,' said Andy Zhou, co-founder of BlockSec and professor at the Chinese University of Hong Kong. 'On-chain transfers are final, so weak key management, unreviewed transaction approvals, or thin compliance checks can turn one mistake into a permanent loss.'
The guide helps businesses answer questions such as whether operating wallets are separated from reserve wallets and if there's a plan for a stablecoin freeze event.
