Justin Sun has made an $8 million strategic investment in River to support its deployment of stablecoin infrastructure within the TRON ecosystem.

River's stablecoin, satUSD, can be minted using USDT, USDD, or USD1 at a 1:1 ratio. It supports cross-chain assets as collateral and is planned for use in liquidity mining and lending on platforms such as SUN.io and DeFi JUST. The first entry point is native sTRX staking rewards.
