Ripple has minted 99% of the total supply of its stablecoin RLUSD in preparation for its launch.The launch of RLUSD poses a challenge to established stablecoins like USDC and USDT in the $1 trillion stablecoin market.Ripple's ability to offer its rail (XRPL blockchain) and establish RLUSD for cross-border payments gives it an edge over competitors.The XRPL community has approved two major amendments, 'fixEmptyDID' and 'fixPreviousTxnID', to expand the use cases of RLUSD.
