DarkPay is a community-driven, privacy-focused BitPay equivalent. Bringing an extended BWS API middleware and merchant system, based on Bitcoin core but using PoS V3, the transactional privacy of users is improved because the value of funds being transferred is obfuscated.
Known as CT/RingCT (Confidential Transactions), this is a privacy feature that was implemented into the Monero protocol.
