Hello this is Doo, Korea Lead & Asia Partnership at Maker Foundation,

MakerDAO's Dai is the largest decentralized stablecoin and it's listed on various exchanges including Coinbase, Bitfinex, Bittrex, and Upbit. It's also used by many entities including UNICEF and HTC.

Currently, there's an initiative where we invite audit companies (both security, legal, and economic) to support Dai payment option to show their support for decentralized and secure blockchain ecosystem.16 audit companies signed up so far. Let me know if your team is interested as well.
