# Casten

DeFi is a decentralized financial system based on smart contracts that function without intermediaries, such as banks or insurances. DeFi applications strive to fulfill the services of traditional finance in a frictionless, global and transparent manner built on the blockchain.

Casten is a DeFi lending protocol where real-world businesses can borrow efficient and risk-priced capital, enabling investors to earn differentiated yields across an array of trade finance and loan products.&#x20;

Currently, top lending protocols in DeFi like Compound, Aave, etc need borrowers to be overcollateralized in order be able to create a borrowing position. *However, Casten is uncollateralised protocol, where various participants are incentivised to secure the protocol and its funds by staking/auditing/originating etc.*
