Liquidium
Liquidium is a decentralized Bitcoin lending protocol where users can borrow BTC against Ordinals, Runes, and BRC-20 tokens, and lend BTC to earn up to 380% APY. Borrowers can secure Bitcoin loans using their digital assets as collateral, with inscriptions safely locked in a Discreet Log Contract (DLC) until repayment, ensuring a secure and fast process. Lenders provide BTC and earn interest; if the borrower repays, the lender receives the BTC plus interest, and if not, the lender receives the collateral. All transactions are natively secured on the Bitcoin blockchain, with no wrapping or bridging, just Bitcoin. Liquidium's non-custodial escrows use DLCs to securely store collateral during a Bitcoin loan. It supports borrowing and lending against Bitcoin assets like Ordinals, Runes, and BRC-20 tokens. Lend your BTC and earn interest; each loan is secured by an inscription in a Bitcoin DLC.

Debifi
Debifi is a non‑custodial, Bitcoin‑backed lending platform that lets borrowers tap into institutional‑grade liquidity without relinquishing control of their coins. Built by Bitcoiners, it uses a strict three‑of‑four multisignature escrow system, keys are generated on a separate device, never held by Debifi, and distributed among borrower, lender, and trusted third‑party signers, to ensure maximum transparency and eliminate collateral rehypothecation. Users connect through a lightweight app to create dedicated escrow addresses on Bitcoin’s blockchain, initiate loan contracts, and manage repayments directly with lenders. Debifi aggregates global liquidity providers to offer flexible loan terms from short‑term funding to five‑year stablecoin or fiat loans, with customizable loan‑to‑value ratios and competitive, risk‑adjusted interest rates. Institutional lenders benefit from over‑collateralization, a tiered margin‑call system, and automatic liquidations.

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.
