Kashi is a lending and margin trading platform, built upon BentoBox, which allows for anyone to create customized and gas-efficient markets for lending, borrowing, and collateralizing a variety of DeFi tokens, stable coins, and synthetic assets. Such a broad diversity of tokens is supported through the use of a unique isolated market framework. Unlike traditional DeFi money markets where high-risk assets can introduce risk to the entire protocol, in Kashi, each market is entirely separate in its own (similar to the Sushiswap DEX), meaning the risk of assets within one lending market has no effect over the risk of another lending market. Traditional lending projects have permitted users to add liquidity into a pool-based system. In these systems, if one of the assets were to drop in price faster than liquidators could react, every user and every asset would be negatively impacted. In this sense, the total risk of pool-based platforms determined largely by the riskiest asset listed on the platform. This risk increases with every extra asset that is added, leading to a very limited choice in assets on most platforms. Kashi’s unique design enables a new kind of lending and borrowing. The ability to isolate risks in individual lending markets means that Kashi can permit users to add any token. In addition, isolating the risks of the different lending markets enables users to achieve leverage in one click, without ever leaving the platform.
The main difference is that Kashi uses lending markets, and isolated risk markets, while other lending platforms both calculate risks globally, such that the solvency of any token can affect the solvency of the whole platform. One important consequence of using isolated risk markets is that Kashi is able to allow any token to be listed [see What are isolated risk markets? in the Kashi FAQ]. Another important consequence is that an elastic interest rate is used to incentivize liquidity in a certain range [see What is the elastic interest rate? in the Kashi FAQ]. Yet another consequence of lending pairs and isolated risk markets is that Kashi’s oracles need to be customizable to provide price feeds for infinitely many tokens.
