Cryptocurrency is a necessary means for blockchain ecosystem which enables running a trusted social network in a decentralized ecosystem. However, cryptocurrency has not only fully carried out its purpose but also has been treated as an insufficient asset when it comes to market utilization. Currently, a large portion of the entire cryptocurrency outstanding is sleeping inside wallets without single transaction, limiting individuals’ access to it and cutting them out from potential investment opportunities. Traditional financial market, though its structurally safe environment, has been discriminating alienated individuals against those possessing privileges of getting access to information faster than the others, also as known as the information asymmetry problem. As a result, the majority of individuals has difficulties in finding attractive investment opportunities with stable and decent return.

DA:Ground has developed a hybrid DeFi(Decentralized Finance) architecture, only taking advantages from both centralized and decentralized models: transparency and stability from the decentralized, and speed and efficiency from the centralized. While common DeFi services in the market try to decentralize all functions including asset management, collateral management and transaction, etc, sandbank's hybrid DeFi model keeps these functions off-chain(central servers) to enhance user experience in a highly efficient way. It maintains other features like instant asset price and transaction records on blockchain, enhancing the integrity of our financial service and providing trustworthiness to it. As a result, sandbank responds more spontaneously to the needs of fast-growing crypto market investors, and simultaneously provide transparent and secure services in a decentralized manner specifically available by blockchain.Learn more about DeFi

What happens if the prices of collateralized cryptocurrencies plunge?

sandbank's Collateral Management System automatically reflects the dramatic change in market condition and calculates collateral value for all outstanding loans. Next, the system requests borrowers to deposit additional collaterals if they want to maintain loans outstanding. If they do so and return the collateral ratio back to the secure level, the loans are safe and continue to go on. If they do not deposit any additional collateral by the given due date, the system immediately sells a portion of collateral and increase the collateral ratio to the secure level.
