What Is Euler Finance (EUL)? A Guide to the Decentralized Lending Protocol

Euler Finance is gaining attention in the world of decentralized finance. Designed to make lending and borrowing more flexible, it allows users to turn nearly any ERC20 asset into collateral.

Its modular design and permissionless approach give both everyday users and developers the freedom to create custom lending markets.

With Euler V2, the protocol has reimagined its architecture to improve capital efficiency, enhance security, and isolate risk.

This guide explores what Euler Finance is, how it works, and why its native token EUL plays an important role in its ecosystem.

Key Takeaways

1. Flexible Lending and Borrowing: Euler allows nearly any ERC20 token to be used as collateral, opening more DeFi opportunities.

2. Modular V2 Architecture: Permissionless vaults and customizable interest rates enable users and developers to manage risk effectively.

3. EUL Token Utility: EUL is used for governance, fee flow auctions, and rewards, empowering the community to influence the protocol.

What Is Euler Finance (EUL)?

Euler Finance is a decentralized lending and borrowing platform on Ethereum. It allows users to lend assets to earn interest or borrow using collateral.

Unlike traditional banks or older DeFi protocols, Euler focuses on modularity and flexibility, giving users more control over how they interact with the ecosystem.

Everyday Users

Euler makes borrowing and lending simple while giving users the freedom to experiment with different strategies.

Depositors can earn interest, while borrowers can access liquidity without relying on centralized institutions.

Developers

With Euler V2, developers can create isolated lending markets for any ERC20 token using the Euler Vault Kit (EVK).

Each vault is independent, allowing tailored interest rate models, oracles, and risk parameters. This ensures that issues in one market don’t impact others, increasing the overall stability of the protocol.

How Euler V2 Works

Euler V2 is a complete redesign of the protocol, emphasizing modularity and risk isolation. The architecture centers around the Euler Vault Kit, which allows the creation of independent vaults for different assets.

Core Components

• Euler Vault Kit (EVK): A toolkit that allows permissionless vault creation and management for lending and borrowing.

• Vaults: Individual lending pools where users deposit assets to earn yield or use them as collateral.

• Oracles: Provide secure price feeds for assets, essential for collateral valuation and liquidation checks.

• Interest Rate Models (IRMs): Determine borrowing and lending rates based on the utilization of each vault.

• Hook Targets: Optional contracts that add custom logic to vault operations for security or advanced features.

• Ethereum Vault Connector (EVC): Acts as a secure entry point for interacting with multiple vaults, allowing atomic execution and cross-vault borrowing.

Euler V2 replaces the single, monolithic pool structure of V1 with isolated, customizable markets.

This reduces systemic risk, improves capital efficiency, and allows users and developers to experiment safely.

EUL Token and Its Utility

The EUL token is Euler’s native ERC20 token, which serves multiple roles in the ecosystem.

Governance

Holders can vote on protocol upgrades, treasury management, and other decisions impacting the Euler DAO. This ensures the community has a say in how the platform evolves.

Fee Flow Auctions

EUL is used to participate in auctions that distribute protocol fees. This process can create deflationary pressure as tokens are burned during the fee collection.

Rewards

Users earn EUL for participating in the protocol, including depositing assets or using specific Euler services.

Token Distribution

• Euler DAO: Around 34% of tokens support the community and ecosystem growth.

• Euler Foundation: About 3.7% are allocated for ecosystem facilitation.

• Strategic Partners: Roughly 39.5% went to early growth partners.

• Euler Labs: Around 26.5% allocated to founders and contributors.

The total supply of EUL is 27,182,818 tokens, reflecting Euler’s homage to the mathematical constant e.
