River has launched a 40% APR deposit activity with a validity period of 45 days, but the upper limit is only $10 million. Therefore, we have to rely on hand to hand speed to grab the quota. Any deposit activity must figure out where the underlying income comes from, otherwise you will become a source of income. River's 40% income this time consists of two parts. Firstly, the stable coin satUSD with an actual return rate of 16.8%, which comes from the satUSD staking pool, protocol incentives, and automated Defi+DeDefi strategy. Secondly, there is a token with an implied return rate of 24%. Each 1U can earn 1.5 River points, which can be exchanged for tokens after TGE. The points issued this time are based on $200 million FDV. @RiverdotInc is a full chain over collateralized CDP stablecoin project, which can mint stablecoins on various chains without the need for a bridge and obtain returns and liquidity. This means that stablecoins such as satUSD can be minted on the B chain after pledging assets on the A chain. It is the first cross chain CDP system built using LayerZero's OFT standard, supporting the deposit of BTC, ETH, BNB as collateral. As it is over collateralized, the minimum collateralization rate is 110%, otherwise it will be liquidated. Alternatively, stablecoins such as USDT can be directly exchanged for satUSD at a 1:1 ratio. The main purpose of adopting this full chain model is to solve the problem of liquidity. In any chain, you can mortgage the corresponding assets and exchange them for a unified asset on the target chain, thus activating the validity of each chain asset, and then using the unified asset as a medium. Prior to this, in order to handle this requirement, you need to go through the process of cross chain collection of assets from multiple chains, then mortgage and exchange them for stablecoins, and then cross chain sending the stablecoin to the target chain you need to use. The whole process is cumbersome and may cause wear and tear, and involves a lot of manual operations. If you are not careful, you may be hacked, The entire process of River is automatically completed in smart contracts, with low loss and high security. Therefore, it is named River in the hope of allowing blockchain assets and liquidity to converge and flow towards their destination like a river. In terms of risk control, the minimum collateral ratio mentioned above is 110%. However, if the total collateral ratio is lower than 150%, a recovery mode will be triggered, and stricter rules will be implemented to restore system health. This is also a key security mechanism within River, which will reduce system pressure by restricting lending and clearing high-risk user positions in advance. Therefore, it is recommended that individual users increase their collateral ratio to 150% or above for greater safety. Because River allows multiple collateral assets to be deposited, and different assets have different risks, River also has specialized risk control measures for isolation, tailoring an independent management approach and safety factor for each asset to regulate loan ratios, coinage limits, etc. The most critical issue with over collateralized stablecoins is how to generate liquidation in a timely manner. River did not use auction mode, but adopted an instant, permissionless liquidation mode. When a user's collateral ratio is below 110%, anyone can trigger liquidation to obtain arbitrage opportunities. This open game system can incentivize more people to participate in identifying and handling single point risks, thereby maintaining the stability of the entire system. And it has a lightning loan clearing mechanism, which can provide instant liquidity without the need for prepayment. Users can repay the settled position debt in a single transaction and repay the funds in the same block. This way, even in the case of insufficient stablecoin funds, the protocol can quickly process clearing. So overall, River has put a lot of effort into the design of the protocol mechanism, especially in risk control. Currently, it supports a total of 8 chains, generating $600 million in collateral and $240 million in satUSD, which is still in a very healthy state in terms of this ratio. Currently, it ranks second among stablecoin users on BNB Chain, only behind its own son ListaDAO.
