About RefCo
RefCo (referral-code.org) helps traders sign up on the right crypto derivatives exchange – with a working referral and the facts that matter before you deposit.
What we do
We focus on the largest exchanges in CoinMarketCap's derivatives ranking and publish one page per exchange with the same structure: a quick answer, key facts, fees, an honest description, pros and cons, safety notes, availability and a FAQ. That makes exchanges easy to compare.
Our methodology
- Market data (open interest, 24h volume, number of markets) comes from CoinMarketCap's derivatives ranking and is dated on every page.
- Fees and leverage are taken from each exchange's official fee schedule for the standard (non-VIP) tier.
- Licences and incidents are based on official announcements and reputable news coverage.
- Review cycle: data is re-checked regularly; the current review date is October 11, 2026.
Independence
We earn referral commissions from the exchanges we list – details in our affiliate disclosure. That never changes the facts we publish, and we always mention weaknesses and restrictions.
