NOWPayments, in collaboration with BlockSec, has released a crypto payment security and compliance checklist covering 25 security control measures.

Crypto payment gateway provider NOWPayments has partnered with blockchain security firm BlockSec to jointly release the *Crypto Payment System Security and Technical Compliance Checklist*, aimed at helping enterprises enhance the security of their crypto payment systems. The checklist covers 9 core security and compliance categories, totaling 25 control measures, spanning areas including private key and wallet security, smart contract security, transaction verification and signing, identity and account management, domain security, on-chain monitoring and incident response, AML/CFT technical compliance, stablecoin freeze risk management, and continuous improvement. NOWPayments noted that key risks facing crypto payment systems include private key leaks, suspicious transactions, account takeovers, and stablecoin freezes. Given the irreversibility of on-chain transfers, enterprises need to establish more robust wallet management, transaction approval, and compliance monitoring mechanisms. Andy Zhou, co-founder of BlockSec, stated that many enterprises mistakenly treat crypto payments as traditional online payments. Since on-chain transactions cannot be reversed, weak key management, unvetted transaction authorizations, and insufficient compliance checks can all lead to permanent financial losses. The checklist is designed for enterprises to use during crypto payment deployment, vendor evaluation, and routine security reviews, helping security, operations, compliance, and product teams jointly identify risks and clarify accountability. NOWPayments currently supports over 350 cryptocurrencies and more than 30 stablecoins, offering crypto payment, automatic conversion, and settlement services for merchants, online platforms, and enterprises. BlockSec provides blockchain security services including smart contract audits, real-time security monitoring, attack defense, and on-chain investigations.
