keys4coins have 0-conf for bch payments
keys4coins accepts 0-conf Bitcoin Cash (BCH) tranactions in their gift card operation.
They have done this for a long time, even before the doublespend proofs are generally available and in use (in the past also for BTC).
To protect themselves, they currently have a safety limit of 100 EUR before 1-conf is required.
Although 0-conf is common in physical stores, and not essential in web stores, the gift cards are money like instruments and the business is exposed to double spend scam attempts for that reason. So kudos to keys4coins to limit the risk as much as possible and do it anyway."
