Aave
Aave is an open source and non-custodial liquidity protocol for earning interest on deposits and borrowing assets. Aave is a decentralized non-custodial money market protocol where users can participate as depositors or borrowers. Depositors provide liquidity to the market to earn a passive income, while borrowers are able to borrow in an overcollateralized (perpetually) or undercollateralized (one-block liquidity) fashion. At Aave, security is our top priority and we are constantly auditing and improving our protocol. The funds are stored in a non-custodial smart contract on the Ethereum blockchain. You control your wallet. Regulated and auditable by code. To ensure top notch security, Aave Protocol has had audits by trail of bits, open zeppelin, consensys diligence, certik, peckshield and certora. All audits are publicly available.

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.

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.
