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。

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：

Rule	Impact	Description
`tools-lens`	MEDIUM	Query vault, account, and oracle data via Lens contracts
`tools-subgraphs`	MEDIUM	Track active accounts and vault factories via subgraph
`tools-interfaces`	MEDIUM	Contract addresses and ABI references

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

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：

Read individual rule files for detailed explanations and code examples:

rules/tools-lens.md
rules/tools-subgraphs.md
rules/tools-interfaces.md

阅读单个规则文件获取详细说明与代码示例：

rules/tools-lens.md
rules/tools-subgraphs.md
rules/tools-interfaces.md
