Introduction & Platform Snapshot
Euler Finance, launched in 2021 by Euler Labs, is a decentralized finance (DeFi) protocol on Ethereum, designed for flexible lending and borrowing of digital assets. By Q1 2025, Euler has regained traction after a significant exploit in 2023, achieving substantial total value locked (TVL) in its lending pools.
The platform supports a wide range of assets, offering competitive yields and low transaction fees, with unique features like permissionless lending and risk-based asset tiering. Euler’s community-driven governance via the EUL token and audited smart contracts enhance trust, though the 2023 exploit underscores ongoing smart contract risks.
Accessible through Euler’s website, the protocol leverages Ethereum’s robust ecosystem, making it a compelling choice for DeFi users, though regulatory uncertainties and technical complexity require vigilance.
Company Background & Reputation
Euler Finance, launched in 2021 by Euler Labs, aims to provide a flexible, user-centric DeFi lending platform on Ethereum. Led by Michael Bentley, the team has developed innovative features like permissionless lending, allowing users to add new assets without governance approval. Euler raised significant funding through a 2021 token sale, backed by investors like Paradigm and Coinbase Ventures, fueling its growth.
The platform faced a major setback in March 2023, when a smart contract exploit led to a $197 million loss, impacting its reputation. By 2025, Euler has recovered through enhanced security measures, full user reimbursement, and transparent communication, rebuilding trust. Partnerships with Chainlink for price oracles and integrations with Ethereum DeFi protocols like Aave bolster its credibility, though the 2023 exploit remains a cautionary note.
Reputation Scoring Summary
Strong recovery and innovation, with concerns from past exploit.

Regulatory Compliance & Licensing
Euler operates as a decentralized protocol on Ethereum, without traditional licenses, relying on blockchain-specific compliance standards. Its permissionless nature and EUL token governance navigate jurisdictional laws, but regulatory scrutiny, such as potential securities classification of EUL, poses challenges in regions like the United States or Europe.
The open-source code, hosted on GitHub, allows public scrutiny, and community governance fosters transparency. Users in restrictive regions like China may face access limitations, requiring awareness of local regulations.
Compliance Scoring Summary
Effective decentralized compliance, though regulatory uncertainties persist.

Interest Rates & Earning Mechanics
Euler offers variable interest rates, typically 3-10% APY for stablecoins like USDC and USDT, and 2-7% for volatile assets like ETH or WBTC, adjusted dynamically based on market conditions. Users can lend assets to earn interest or provide liquidity for rewards, with no lock-up periods ensuring flexibility. Transparent reporting on pool utilization and rates via the Euler interface ensures clarity, though yield variability requires active monitoring. The platform’s risk-based asset tiers (collateral, cross, isolated) optimize yield and safety.
Interest Rates Scoring Summary
Competitive yields with flexible mechanics, though variability requires attention.

Supported Assets
Euler supports over 30 assets, including ETH, USDC, USDT, DAI, WBTC, and permissionless tokens added by users, leveraging Ethereum’s ecosystem for broad compatibility and liquidity. The permissionless lending feature allows new assets without governance approval, a unique advantage. Integration with decentralized exchanges like Uniswap ensures deep liquidity, though the asset range is narrower than multi-chain platforms like Aave.
Supported Assets Scoring Summary
Broad asset support with permissionless flexibility, though ecosystem-specific.

Loan Terms & LTV Options
Euler’s lending model offers collateralized loans with Loan-to-Value (LTV) ratios up to 75% for stablecoins and lower for volatile assets, with interest rates of 2-8% APR. Loans are open-ended with no prepayment penalties, and automated liquidations protect lenders. Real-time alerts via the Euler interface manage risks, though market volatility requires vigilance. The asset tiering system minimizes risk by categorizing assets based on volatility.
Loan Terms Scoring Summary
Flexible loan terms with effective risk management, though volatility is a concern.

Fees & Cost Structure
Euler’s transaction fees are tied to Ethereum’s gas costs, which are moderate on Layer-1 but can be optimized via Layer-2 integrations. DeFi protocols like Euler charge minimal fees for lending or borrowing, transparently reported, making it cost-effective compared to high-gas platforms. Users pay gas fees for transactions, typically under $1 with Layer-2 solutions.
Fees Score Scoring Summary
Low protocol fees, transparent, though Ethereum gas costs vary.

Security Architecture & Custody
Euler employs audited smart contracts, with post-2023 audits by firms like OpenZeppelin addressing vulnerabilities from the exploit. Multi-signature wallets and Chainlink price oracles enhance security, and no major breaches have been reported since 2023. Users retain control via non-custodial wallets like MetaMask, minimizing counterparty risk, though smart contract vulnerabilities remain a concern.
Security & Custody Scoring Summary
Robust security with audited contracts, minor risks from past exploit.

Insurance & Risk Mitigation
Euler lacks traditional insurance, relying on over-collateralization (e.g., 120% of loan value) and automated liquidations to mitigate risks. Regular stress tests ensure resilience against market volatility, but users must remain cautious of smart contract vulnerabilities and lack of insurance coverage.
Risk Mitigation Scoring Summary
Strong risk mitigation, though no insurance coverage.

User Experience (Web & Mobile)
Euler’s interface, accessible via its website, offers intuitive navigation and real-time data on lending pools and loan metrics. Integration with wallets like MetaMask is seamless, though mobile access via browsers requires technical familiarity. Educational resources support users, enhancing accessibility.
UX Scoring Summary
User-friendly interface, though technical knowledge needed.

Customer Support & Community
Euler relies on community-driven support through X, Discord, and forums, with regular AMAs fostering engagement. Comprehensive documentation aids self-reliance, but the lack of centralized support may challenge some users.
Customer Support Scoring Summary
Strong community engagement, though decentralized support may limit accessibility.

Unique Features & Differentiators
Euler’s standout features include:
- Permissionless Lending: Users can add new assets without governance approval.
- Asset Tiering: Collateral, cross, and isolated tiers optimize risk and yield.
- EUL Governance: Community-driven decisions enhance transparency.
- Defer Liquidity Checks: Allows flexible borrowing strategies.
These features distinguish Euler from platforms like Aave or Compound, emphasizing flexibility and innovation.
Unique Features Scoring Summary
Innovative features with strong DeFi integration.

Historical Performance & Market Events
Euler launched successfully in 2021, gaining traction with its permissionless lending model. The March 2023 exploit, costing $197 million, was a significant setback, but Euler’s full reimbursement and enhanced security measures by 2024 restored trust. By 2025, TVL growth and integrations with Ethereum DeFi protocols highlight its recovery and resilience.
Track Record Scoring Summary
Strong recovery, though past exploit raises caution.

Risks & Transparency
Euler’s open-source code, hosted on GitHub, and EUL governance ensure transparency. Clear reporting on yields and loans fosters trust, though decentralized governance may limit direct accountability.
Transparency & Risk Scoring Summary
High transparency with governance-driven accountability.

Future Outlook & Roadmap
Euler plans to expand asset support, enhance Layer-2 integrations, and improve user interfaces by 2027. Continued focus on security and governance aims to solidify its position as a leading DeFi protocol, though regulatory navigation remains ongoing.
