List of Decentralised Borrowing & Lending projects on Optimism (2026)

Sky Money is a self-custodial yield app that lets users earn on stablecoins through the Sky Savings Rate and curated lending vaults. Depositing into the savings module mints a savings token that grows in value as yield accrues, while vaults allocate stablecoin deposits across lending markets. Users can also stake the governance token to earn rewards, borrow stablecoins against the staked position, and delegate voting power. Built-in conversion moves between the protocol's stablecoins and legacy tokens at fixed rates, alongside trading between ecosystem tokens. The app runs across multiple blockchains, and users keep full control of deposited funds throughout.

ChangeNOW Exchange is a decentralised exchange that lets users swap cryptocurrencies without creating an account. It matches trades using liquidity sourced from multiple venues and offers both fixed and floating rate options for each swap. The service also includes a fiat-to-crypto on-ramp so users can acquire assets using traditional payment methods, trading directly from their own wallets across multiple supported blockchains.

Compound v2 provides pooled liquidity markets enabling users to supply assets as collateral and borrow multiple asset types. The system uses cTokens as receipt tokens representing supplied assets, with interest rates determined algorithmically based on utilization. Users can borrow any supported asset against their collateral while earning interest on supplied funds.

Compound III provides single-asset borrowing markets with isolated collateral pools for enhanced security and capital efficiency. Each deployment supports borrowing one base asset using approved collateral types that remain user property unless liquidated. The protocol features reduced gas costs, lower liquidation penalties, and algorithmic interest rates while eliminating pooled-risk across multiple borrowable assets.

Nostra is a decentralized finance application on Starknet that combines lending and borrowing, liquidity pools, token swaps, and cross-chain bridging in one connected-wallet experience. Users supply and borrow assets against tokenized collateral positions using risk tiers, efficiency modes, and dynamic interest rates, with flash loans and automated liquidation protection built in. The platform also runs automated market maker pools with verified, experimental, volatile, stable, and degen risk designs that feed liquidity into the swap function for token exchanges. A bridging module, powered by a cross-chain interoperability partner, moves assets between Starknet and other blockchain networks.

Balanced is a cross-chain DeFi platform providing a money market and exchange across multiple blockchains. The money market enables users to supply crypto assets to earn variable-rate interest and borrow against cross-chain collateral. The exchange aggregates prices from multiple decentralized exchanges via SODAX Intents, settling cross-chain swaps within seconds. The bnUSD stablecoin is accessible as a fixed-rate borrowable asset, backed by over-collateralized crypto collateral.

Venus Protocol operates algorithmic money markets enabling over-collateralized lending and borrowing through core and isolated pool architectures. The system calculates interest rates based on supply and demand dynamics while maintaining collateral ratios through automated liquidation mechanisms. Risk management separates assets into distinct pools with independent parameters including collateral factors and rate models. Protocol revenue distributes to XVS stakers through Venus Prime using non-transferable soulbound tokens that boost yields based on staking duration and market participation. Users mint VAI stablecoin against supplied collateral with peg stability maintained through direct swaps between VAI and other stablecoins at fixed ratios.

PWN Protocol is a permissionless peer-to-peer lending protocol that lets users borrow and lend using virtually any digital asset as collateral. Loans are set up with fixed terms negotiated between counterparties, and because pricing is oracle-less, collateral cannot be seized through price-based liquidation, only through missed repayment. The protocol supports several access modes, from simplified fixed-term note strategies to curated markets and a fully customizable peer-to-peer marketplace, and integrates with a range of external DeFi lending and yield venues to source liquidity and collateral options.

Moonwell Protocol is a decentralized lending and borrowing platform that lets users supply digital assets to earn yield or borrow against posted collateral. It operates through isolated markets with dynamic, algorithmic interest rates and includes tokenized vaults that route deposits across lending markets for aggregated yield. The protocol is governed by its community and runs across multiple blockchains, giving users a consistent interface for money-market activity regardless of network.

Arcadia Finance is a decentralized liquidity management platform that lets users set up automated positions on automated market maker exchanges. It provides curated one-click strategies, custom liquidity ranges, and automated compounding and rebalancing for concentrated and virtual liquidity positions, alongside lending pools for passive yield. The platform is non-custodial, giving users self-owned accounts that retain control of assets while automations execute within onchain boundaries.

Spark is a decentralized protocol providing stablecoin savings vaults and a non-custodial lending market, powered by automated cross-chain capital deployment infrastructure. Savings vaults accept multiple stablecoins and ETH, with yield generated by allocating capital across DeFi protocols, CeFi venues, and real-world assets via the Spark Liquidity Layer. SparkLend enables borrowing of USDS and USDC at governance-set rates against curated collateral including ETH and liquid staking tokens, deployed across multiple EVM-compatible networks.

Pike Markets is a decentralized money market protocol featuring integrated DEX functionality, multi-tier governance, and cross-chain capabilities. The system supports customizable lending markets with tailored risk parameters through modular architecture and dual-oracle pricing infrastructure.

Gearbox Protocol is a decentralized borrowing and lending protocol that pairs passive lending pools with leveraged Credit Accounts. Lenders deposit assets into pools and receive share tokens that accrue the interest paid by borrowers. Borrowers open Credit Accounts that hold collateral and debt and execute approved actions on integrated protocols, with solvency checks and liquidations protecting the pool. Curators can deploy their own markets on the same infrastructure, setting supported assets, debt ceilings, rates, and oracle rules.

Stormbit is non-custodial settlement software for tokenized-asset transactions, used by holders of assets such as BTC or ETH and by capital providers who fund positions. Holders select a program, Harvest for income above a chosen price, Accumulate for a paid commitment to buy at a chosen price, or Prime for fixed-term credit under a protective floor and cap, and a counterparty prices the terms before the holder authorizes settlement from their own wallet. Prime blocks price-based liquidation during the protected term, opening it permissionlessly only after maturity plus four hours. Capital providers fund these programs through vaults, depositing into epoch-based pools and receiving a share redeemable as positions settle, with variable, unguaranteed returns.

Exactly Protocol implements autonomous fixed and variable interest rate markets through utilization-based pricing, enabling users to lend and borrow crypto assets across multiple maturity pools. The system determines fixed rates based on pool demand rather than token pricing while maintaining capital efficiency through automated liquidity provision between variable and fixed rate pools.
