Justin Sun, the founder of TRON, has invested $8 million in River to enhance the deployment of its stablecoin infrastructure within the TRON ecosystem. This strategic investment aims to integrate River's chain-abstract stablecoin, satUSD, which can be minted at a 1:1 ratio with USDT, USDD, or USD1. The stablecoin will support cross-chain assets as collateral and is set to be used in liquidity mining and lending on platforms like SUN.io and DeFi JUST. The initiative will initially focus on native sTRX staking rewards.
