NEST is a decentralized financial (DeFi) service platform. At present, NEST DAPP based on Ethereum has been launched to centralize the digital asset mortgage lending function: support mortgage ETH to borrow TUSD stable currency, and support mortgage HT, BAT, OMG, LOOM and other mainstream ERC20 Token to borrow ETH and TUSD stable currency. NEST adopts the mechanism of “chain contract” + “excess mortgage” + “no need to make up the position”, and the real digital assets [decentralized + peer-to-peer] mortgage lending.
