Teller is a lending platform combining traditional loan access with on-chain borrowing. Users can pre-qualify for unsecured loans without pledging assets or borrow USDC against crypto and tokenized assets such as BTC, ETH, and stocks. Its asset-backed lending model uses fixed action windows rather than continuous price-based margin calls, allowing borrowers to retain exposure to their assets while accessing liquidity. Teller also offers portfolio tracking, stablecoin yield features, and an on-chain Teller Score designed to unlock no-collateral borrowing. The protocol operates across networks including Ethereum, Base, Arbitrum, Polygon, and HyperEVM.
