About Resfinex exchange

Resfinex is one of a kind when it comes to crypto exchanges. The thing is that Resfinex was developed from scratch, unlike many other exchanges that were built with standardized engines. That is why Resfinex is much faster and more user-friendly.

If you want to sign up on Resfinex, all you have to do is confirm your email. What’s more, you can forget about KYCs altogether — there is no need to complete them on this platform! Basically, the most tradable coins on Resfinex are Ethereum and ERC-20, which have sound liquidity and are paired with USDT.

The exchange is fully mobile-friendly so that you can trade whenever you want.

Resfinex aims to support decentralization and promising crypto projects, too. The exchange is run by a small but highly motivated team of professionals from the British Virgin Islands.

Bounty campaign encouraging users to enable 2FA

Both ADAMANT and Resfinex are companies which encourage security and privacy. We decided to run shared Bounty campaign for Resfinex users to secure their accounts.

Users who set up ADAMANT 2FA on Resfinex, will receive bounty reward of 30 ADM and 3 RES tokens. You can find out more about 2FA bounty campaign on Resfinex.
