AI Agents Execute Complex DeFi Lending Moves Without User Keys

**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.

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 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 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.
