TL;DR
- Aave integrates CoW’s solver network to unify swaps and improve pricing with MEV-protected execution across its entire platform.
- The platform adopts batch auctions and shifts away from traditional aggregators toward a solver-driven model that avoids fixed routes and reduces the likelihood of attacks.
- The agreement adds an intent-based flash loan system that enables arbitrage, refinancing, and automation through solver-optimized routes.
Aave strengthens its integration with CoW Swap and reshapes how swaps and liquidity are managed across its platform.
The expanded agreement will turn Aave into a unified environment where asset swaps, collateral swaps, debt swaps, and functions like repay with collateral are executed through CoW Protocol’s batch-auction system, with built-in MEV protection. The goal is to reduce operational costs, improve pricing, and eliminate the need for separate interfaces for each stage of a loan’s lifecycle.

Aave Introduces Intent-Based Flash Loans
The key shift is moving away from the traditional logic of DEX aggregators toward a model driven by a solver network that competes to deliver the best execution. The batch-auction structure removes predefined routes, reduces exposure to frontrunning and sandwich attacks, and gives Aave a more consistent pipeline for executing sensitive swaps, especially in leveraged positions or complex collateral adjustments.
The update also adds a new component to the ecosystem: an intent-based flash loan system. This model allows users to define the final outcome while delegating the technical resolution to solvers, which can build optimal routes without relying on a single predefined path. This enables more efficient arbitrage, refinancing operations that previously required multiple steps, and advanced automation for programmable liquidity management.
Why CoW Protocol?
CoW Protocol processes over $10B in monthly volume, and Aave argues that this track record is one of the main factors behind the strengthened alliance. The integration follows nearly two years of coordinated development between both teams, aimed at incorporating a system with greater onchain transparency, MEV-resistant execution, and verifiable savings for users who perform frequent swaps.
Aave and CoW Swap note that this is only the beginning. The roadmap includes a broader suite of intent-based products where users define outcomes and solvers compete to fulfill them securely, efficiently, and verifiably.
CoW-powered swaps are now live for assets, collateral, and debt. aToken swaps will remain on CoW Swap.
