The DeFi platform mentioned in the article is Gains Network ($GNS). It uses a GMX-style trading system where users trade against a pooled DAI and utilizes Chainlink oracles to determine asset prices.
Based on the platform stats dashboard (

What caught my attention is that the forex pairs generate almost as much volume as their crypto pairs. The commodity pairs still lagging behind though, typically registering daily volumes in the single-digit millions. But still, the fact that there's a functional platform in the DeFi space to trade forex with such significant daily volume is remarkable. Especially considering that we're still in a bear market.
