The growth of River's TVL is evident, but what about its quality? Recently, River's TVL surged from $300M to $600M, nearly doubling in just a month and a half. The numbers are impressive, but the more critical question is: how sustainable is this growth? Is it reliant on short-term incentives? Many DeFi protocols initially rely on high APY incentives to climb the rankings, but funds often come in quickly and leave just as fast. In River's TVL growth, while the yield from satUSD+ is a significant attraction, there haven't been extreme high rates, indicating that the funds are not purely profit-driven, and the growth foundation is relatively stable. The real use cases of satUSD satUSD has already been split, collateralized, and lent in protocols like Pendle and Lista. Users are not just minting it and leaving it; they are genuinely participating in the secondary market circulation. Funds are being utilized within the ecosystem rather than just locked up, which is a key indicator of whether growth can be sustained. Comparison with mainstream stablecoins Compared to USDT/USDC, the trading pair depth of satUSD is still limited, but it has already formed a certain scale in some markets (like Pendle). If it can expand more cross-chain payment and trading scenarios in the future, the quality of growth will further improve. Retention and stickiness Community-driven initiatives like River4Fun allow some funds and users to engage not just once but form long-term interactions. This social binding can enhance fund retention rates and avoid purely short-term mining and selling. ▰▰▰▰▰ Summary The growth of River's TVL is not only reflected in the numbers but also shows a certain quality: ※ No excessive reliance on short-term incentives ※ Signs of user retention and interaction ※ satUSD is being genuinely used within the ecosystem However, whether this can be maintained in the future will depend on the trading depth of satUSD and the sustainability of protocol revenue. If funds are merely minted and collateralized without actual consumption scenarios, growth may be difficult to sustain long-term. In my view, the project should have more deployments and plans in the future, such as expanding new ecosystem collaborations, enhancing satUSD's payment and lending applications across different chains, and further amplifying usage demand through community interactions like River4Fun. Once these aspects gradually materialize, River's growth curve is expected to shift from mere capital influx to long-term usage and retention!
