1delta Unifies Three Aave Versions Into Single Data Model for Integrators
1delta Unifies Three Aave Versions Into Single Data Model for Integrators
🔧 Three Protocols One Interface
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.
4/ Decimal avoided that by integrating 1delta as one lending node. One API key. One REST interface. One standardized data model across Aave, Compound, Morpho, Silo, and other lenders.
How do you bring thousands of DeFi lending markets to a no-code automation platform without integrating every protocol separately? @DecimalAt did it through one integration with the 1delta API. New case study 🧵
🤝 @DecimalAt integrated DeFi lending into its no-code Web3 automation platform through one API. • ~3,000 lending markets • 121 lender deployments across six chains • One standardized data model • Integrated and tested in a single month Instead of building and
Aave V2, V3, and V4 share a name, but not the same architecture, field structure, rate model, or risk logic. For integrators, they are effectively three separate protocols. Here is how 1delta maps all three into one unified data model so they can be queried identically
AI Agents Execute Complex DeFi Lending Moves Without User Keys
**Autonomous DeFi Operations Achieved** AI agents have successfully executed complex leveraged lending position migrations across protocols without accessing user private keys. The operation involved: - Flash loan initiation - Debt repayment - Collateral withdrawal - Re-deposit to new protocol - Re-borrowing - All executed atomically in a single transaction **Independent Convergence** Two separate development teams built this capability independently, arriving at the same architectural solution—suggesting a natural design pattern for AI-driven DeFi operations. **Technical Implementation** The system uses [1delta's lending primitives](https://www.1delta.io/blog/how-ai-agents-use-1delta-to-manage-onchain-lending) to enable programmatic execution while maintaining user custody. This allows for: - Agent-driven leverage adjustments - Rules-based rebalancing - Automated hedging and short execution Users retain full control of strategy and policy while the protocol handles on-chain execution.
1delta Standardizes 3,000+ DeFi Lending Markets Into Single Queryable Layer
Finding the best USDC lending rate in DeFi requires comparing thousands of markets with different contracts, rate models, and risk parameters. **1delta's solution:** - Maps 3,000+ fragmented lending markets into one standardized data layer - Aggregates 200+ lending protocols across 50+ chains - Eliminates need for separate integrations with Aave, Morpho, Compound, and other protocols - Provides single interface for comparing rates and parameters The platform addresses DeFi's fragmentation problem by creating a unified, queryable system that makes lending market comparison straightforward.

1delta Integrates 121 Lenders Across Six Chains in Single Workflow
**1delta has completed a major integration milestone** after 1,014 days of development: - **121 lender deployments** integrated - **~3,000 lending markets** now accessible - **Six blockchain networks** supported - All accessible through **one reusable workflow block** **The technical challenge:** Each lender uses different contracts, rate formats, position models, and risk parameters. Across multiple chains, this required building, testing, and maintaining dozens of adapters. **The solution:** A unified workflow that consolidates access to diverse lending protocols, simplifying the complexity of cross-chain lending integrations.
1delta's Compound Integration Clears Certora Security Audit with Zero Critical Findings
**1delta has successfully completed a security audit by Certora for its Compound integration, with zero critical findings reported.** Key highlights: - All identified issues have been resolved - The integration is now fully audited and ready for deployment - 1delta operates as an onchain API for lending and borrowing across **50+ chains** and **200+ protocols** The audit validates 1delta's infrastructure for connecting lender liquidity with DEX liquidity, enabling decentralized margin trading with up to 10x leverage. Users can build leveraged long/short positions while benefiting from competitive borrow rates in DeFi lending protocols.
