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

Sky Money is a self-custodial app for earning yield on stablecoins. Users supply stablecoins to the Sky Savings Rate, curated lending vaults, a variable-rate pool that funds SKY-backed borrowing, or a fixed-yield market, and can receive ecosystem token rewards for supplying USDS. Users can stake SKY to accrue staking rewards and borrow USDS against the staked position. The app converts between USDC and USDS in both directions without fees. It runs across multiple blockchains, and users keep custody of their funds.

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 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.

SODAX is a cross-network execution and liquidity protocol that coordinates financial actions across multiple blockchain networks through a solver-based intent model. A proprietary solver evaluates execution paths and routes user intents through a multi-bridge architecture combining proprietary relays with third-party bridging protocols. An integrated money market provides lending and borrowing infrastructure that also serves as execution liquidity for cross-network settlement.

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 is a decentralized money market where users supply assets to earn interest and borrow against collateral. The core pool sets interest rates by supply and demand, offers E-Mode for more efficient borrowing against related assets, and liquidates undercollateralized positions. Users can mint the VAI stablecoin against collateral and open leveraged positions in a single transaction. Liquidity Hub vaults route one deposited asset across several yield sources. Venus Prime boosts yields for XVS stakers through non-transferable tokens funded by protocol revenue.

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 Savings is a savings product that lets users deposit supported assets into vaults and earn a governance-set rate on the same asset. Yield comes from the Spark Liquidity Layer, which allocates capital across DeFi, centralized finance, and real-world asset strategies, and deposits stay withdrawable. The same app includes SparkLend, a non-custodial money market where users supply assets and borrow against curated collateral at governance-set rates. Vaults and markets run on multiple EVM-compatible blockchains.

Pike Markets is a decentralized money market with integrated exchange functionality for correlated assets. Users supply assets to earn yield, borrow against collateral, and swap assets whose liquidity can also serve as lending collateral. Governors create custom lending markets with their own risk parameters, and each market stays isolated from the rest. Governance uses multiple tiers with time-delayed execution of protocol changes.

Gearbox Protocol is an onchain lending and leverage protocol where lenders deposit assets into pools and earn the interest paid by borrowers. Borrowers open Credit Accounts that hold collateral and debt and can act only on approved protocols, with solvency checks and liquidations protecting the pool. Curators deploy their own markets on the same contracts, setting assets, debt ceilings, rates, and oracle rules.

Kapan Finance is a lending aggregator that manages DeFi borrowing and lending positions across multiple protocols and blockchains from one screen. Flash-loan-funded atomic transactions let users refinance, loop, swap collateral, or move a whole position to another protocol with one signature and no extra capital. The app is non-custodial, charges no protocol fee, and is used by borrowers looking for lower rates.

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.
