El Dorado is a stablecoin-powered payments SuperApp for Latin America whose public API provides crypto onramp/offramp (buy and sell) infrastructure across Argentina, Brazil, Colombia, Peru, Bolivia, Panama, Paraguay, the Dominican Republic and more.

Authentication uses per-partner ClientID and ReferralID headers plus a JWT bearer token obtained via an OTP login flow. El Dorado is backed by Multicoin Capital, Coinbase Ventures and Berkeley SkyDeck and has surpassed 500,000 users.
