Euler Lens & Data Agent Skill
Developer tools and data access guide for Euler Finance V2. Covers Lens contracts, subgraphs, interfaces, and deployment tools.
When to Apply
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
Rule Categories
| 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 |
Quick Reference
Lens Contracts
- 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
Subgraphs
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)
