Ripple's USD-pegged stablecoin RLUSD has rapidly grown to a $170 million market cap since its December launch, outpacing internal projections. The token is gaining traction through increased institutional interest, DeFi liquidity pool usage, and NGO adoption. Ripple CEO Brad Garlinghouse predicts the stablecoin will be in the top five by year-end, bolstered by recent regulatory developments and potential cross-border financial applications.
