TrueFi
Meet TrueFi, the DeFi protocol for uncollateralized lending. Earn high yields on stablecoin loans and borrow capital without collateral. We’re proud to introduce TrueFi, a protocol for uncollateralized lending, and TRU, the native token used for staking and voting on loan requests. The goal of TrueFi is to bring uncollateralized lending to DeFi. This helps cryptocurrency lenders enjoy attractive, sustainable rates of return, while giving cryptocurrency borrowers predictable loan terms without requiring collateral. Importantly, all lending and borrowing activity on TrueFi is fully transparent, allowing lenders to fully understand participating borrowers and flows of funds engaging with TrueFi. Lenders (like you) add TrueUSD into a TrueFi pool to be used for lending, earning interest and farming TRU. Any unused capital is sent into the Curve protocol to maximize earnings. Borrowers (like OTC desks, exchanges, and other protocols) submit proposals to borrow capital from the pool.

Arch
Arch Lending offers crypto-backed loans that enable digital-asset holders to unlock liquidity without selling their holdings. You can pledge Bitcoin, Ethereum, or Solana as collateral, receive funding in fiat USD or USDC, pay no credit check, access funds usually within the same day, and avoid asset rehypothecation. Your collateral remains in qualified custody and is never lent out or otherwise deployed. From an APR starting at around 9.50 %, loans feature flexible terms (up to 24 months), optional pay-down or roll-over, and the ability to increase your borrowing as your collateral appreciates. The platform emphasises trust and security, stating that the business model does not make use of the client’s assets and all collateral is held one-to-one in secure custody. Arch aims to support both individual and institutional borrowers, with specialist services for “private wealth” clients and bespoke institutional lending.

Teller
Teller is a decentralized lending protocol that offers time-based, no-margin-call loans using any Ethereum asset or ERC-20/NFT as collateral, enabling borrowers to access liquidity for 1–30 days without being liquidated due to price fluctuations so long as they repay on time; collateral is placed in isolated escrow vaults and loans can be refinanced or extended based on prevailing offers. Lenders create custom loan terms and keep supplied funds in their own wallets, allowing them to make unlimited offers with the same capital while retaining control, and if a borrower defaults, liquidity providers have first refusal to liquidate and seize collateral. The system emphasizes safety and transparency with audited smart contracts (insured by Sherlock up to defined limits), and it supports isolated pools and perpetual-style structures to give users credit-like access to DeFi capital.
