1delta Unifies Three Aave Versions Into Single Data Model for Integrators
**1delta has created a unified data model** that allows developers to query Aave V2, V3, and V4 through a single interface, despite the protocols having different architectures, field structures, and risk logic.
**Key technical achievement:**
- Maps three distinct Aave versions into one standardized data model
- Enables identical queries across all Aave deployments
- Eliminates need for separate integrations per protocol version
**Real-world application:**
Decimal, a no-code Web3 automation platform, demonstrated the value by integrating ~3,000 DeFi lending markets across 121 deployments through one 1delta API integration. This approach replaced the need to build separate adapters for Aave, Compound, Morpho, Silo, and other lending protocols.
**Integration efficiency:**
- One API key
- One REST interface
- Completed and tested in a single month
The solution addresses a practical challenge for DeFi integrators: treating protocol versions that share a name but differ fundamentally in implementation as separate systems, while maintaining a consistent developer experience.
