Euler Lens & Data Agent Skill

Euler Lens & Data Agent 技能指南

Developer tools and data access guide for Euler Finance V2. Covers Lens contracts, subgraphs, interfaces, and deployment tools.
Euler Finance V2 开发者工具与数据访问指南，涵盖Lens合约、subgraph、接口及部署工具。

When to Apply

适用场景

Reference these guidelines when:
  • Querying account positions and health using AccountLens
  • Querying vault data using Lens contracts (VaultLens, OracleLens, IRMLens, UtilsLens)
  • Tracking active accounts via Euler subgraph
  • Looking up contract addresses and ABIs
  • Building dashboards or analytics for Euler
  • Integrating with Euler from frontends or bots
在以下场景中可参考本指南：
  • 使用AccountLens查询账户持仓状况与健康度
  • 使用Lens合约（VaultLens、OracleLens、IRMLens、UtilsLens）查询金库数据
  • 通过Euler subgraph追踪活跃账户
  • 查询合约地址与ABI
  • 为Euler构建仪表盘或分析工具
  • 从前端或机器人中与Euler进行集成

Quick Reference

快速参考

Lens Contracts

Lens合约

  • AccountLens - Query account positions, liquidity, health factor, time to liquidation (TTL)
  • VaultLens - Query vault state, configuration, LTVs, IRM info
  • OracleLens - Check oracle configuration and prices
  • IRMLens - Interest rate model details and calculations
  • UtilsLens - Utility functions: APY calculations, token balances, allowances
  • EulerEarnVaultLens - Query EulerEarn vault data and strategies
  • AccountLens - 查询账户持仓、流动性、健康系数、清算倒计时（TTL）
  • VaultLens - 查询金库状态、配置、LTV、IRM信息
  • OracleLens - 查看预言机配置与价格
  • IRMLens - 利率模型详情与计算
  • UtilsLens - 实用函数：APY计算、代币余额、授权额度
  • EulerEarnVaultLens - 查询EulerEarn金库数据与策略

Subgraphs

Subgraph

The subgraph is intentionally minimal - use Lens contracts for detailed data:
  • Vault - Track which factory created each vault
  • TrackingActiveAccount - Active accounts indexed by address prefix (first 19 bytes)
  • TrackingVaultBalance - Per-account vault balances and debt (at the time of the last update)
Subgraph设计得较为精简——如需详细数据，请使用Lens合约：
  • Vault - 追踪每个金库的创建工厂
  • TrackingActiveAccount - 按地址前缀（前19字节）索引的活跃账户
  • TrackingVaultBalance - 每个账户的金库余额与债务（基于上次更新时的数据）
