euler-vaults — Руководство по работе с DeFi протоколом Euler Finance

--- name: euler-vaults description: Core guide for interacting with Euler Finance V2 protocol. This skill should be used when building DeFi integrations, managing lending positions, or understanding Euler architecture. Triggers on tasks involving lending, borrowing, collateral, liquidation, EVC, EVK, or core Euler operations. For specialized topics, see companion skills. license: MIT metadata: author: Euler Labs version: "1.0.0" --- # Euler Finance Agent Skill Core guide for interacting with Euler Finance V2 protocol. Contains rules across 5 categories covering vault operations, EVC orchestration, risk management, architecture concepts, and security. ## Companion Skills For specialized topics, use these companion skills: - **euler-irm-oracles** - Oracle adapters, EulerRouter, price resolution, Interest Rate Models - **euler-earn** - EulerEarn yield aggregation, strategies - **euler-advanced** - Hooks, flash loans, fee flow, rewards - **euler-data** - Lens contracts, subgraphs, contract interfaces, developer tools ## When to Apply Reference these guidelines when: - Depositing, borrowing, or managing positions on Euler vaults (EVK) - Batching operations via the Ethereum Vault Connector (EVC) - Monitoring health factors and liquidation risk - Understanding Euler architecture (vault types, market design) - Security practices and audit information ## Rule Categories by Priority | # | Category | Impact | Prefix | Key Questions | |---|----------|--------|--------|---------------| | 1 | Vault Operations | CRITICAL | `vault-` | Get APY, deposit, borrow, create market | | 2 | EVC Operations | CRITICAL | `evc-` | Batch calls, sub-accounts, operators | | 3 | Risk Management | HIGH | `risk-` | Check health, liquidation, risk managers, curators | | 4 | Architecture | HIGH | `arch-` | Market design, vault types | | 5 | Security | CRITICAL | `sec-` | Audits, best practices | ## Quick Reference ### 1. Vault Operations (CRITICAL) - `vault-get-apy` - How to get vault APY and interest rates - `vault-deposit` - How to deposit assets into a vault - `vault-borrow` - How to borrow assets from a vault - `vault-repay` - How to repay borrowed debt - `vault-create-market` - How to create a new vault/market ### 2. EVC Operations (CRITICAL) - `evc-batch` - How to batch multiple operations atomically - `evc-sub-accounts` - How to use sub-accounts for isolated positions - `evc-operators` - How to delegate control via operators - `evc-enable-collateral` - How to enable vault as collateral ### 3. Risk Management (HIGH) - `risk-check-health` - How to check account health factor - `risk-liquidation` - How liquidations work on Euler - `risk-managers` - Understanding risk manager roles ### 4. Architecture (HIGH) - `arch-market-design` - Understanding Euler market design - `arch-vault-types` - Core, Edge, and Escrow vault types ### 5. Security (CRITICAL) - `sec-audits` - Security practices and audit information ## Core Protocol Components ### Ethereum Vault Connector (EVC) The EVC is the foundational layer mediating between vaults. It provides: - **Batching**: Execute multiple operations atomically - **Sub-accounts**: 256 isolated positions per address - **Operators**: Delegate control over your accounts to other addresses - **Deferred checks**: Temporarily violate constraints within a batch ### Euler Vault Kit (EVK) Credit vaults extending ERC-4626 with borrowing: - Standard ERC-4626 deposit/withdraw/mint/redeem - Borrow and repay functionality - Collateral and controller management - LTV ratios (borrow LTV vs liquidation LTV) ## How to Use Read individual rule files for detailed explanations and code examples: ``` rules/vault-get-apy.md rules/evc-batch.md rules/risk-check-health.md ``` Each rule file contains: - Brief explanation of why it matters - Incorrect code example with explanation - Correct code example with explanation - Additional context and references ## Full Compiled Document For the complete guide with all rules expanded: `AGENTS.md`
