On July 21st, 2023, After a successful  [governance vote](https://app.nexusmutual.io/governance/view?proposalId=197)  from Nexus Mutual, CoW Swap processed a  [large trade for the insurance protocol](https://twitter.com/CoWSwap/status/1682450015237857280?s=20)  using the exchange’s signature intent-based trading design and MEV protection.

## Trade Details

Nexus Mutual swapped 14,390 ETH from its capital pool for an equivalent amount in rETH. They did so in two separate orders, the first order swapped  [250 ETH for 231.8 rETH](https://explorer.cow.fi/orders/0x29a83c4990db493b7fbf47ed821288340b4e9394524b1da151251d274d64e150cafea5c050e74a21c11af78c927e17853153097d64baae44?tab=overview)  and the second order swapped  [14,140 ETH for 13,117.148 rETH](https://explorer.cow.fi/orders/0x5e84d3e19341b77c362f37e706b153e460deb929d850bec7d9697a631fe4596fcafea5c050e74a21c11af78c927e17853153097d64bab666?tab=overview).

The overall order stats:

-   **USD value of the trade**: $27.3 million
-   **Minimum asset amount**: 13,362 rETH
-   **Maximum asset amount**: 13,400 rETH
-   **Amount the DAO received**: 13,409.04 rETH

## Why CoW Swap?

CoW Swap’s solver competition ensured that Nexus Mutual received the best possible execution price, even after announcing the trade details publicly in a governance proposal ahead of time.

CoW Swap provided several benefits for this trade:

1.  Protection from attack vectors caused by the delayed execution
2.  A limit order that guarantees some minimum amount for the assets
3.  Minting rETH through CoW Swap directly, instead of swapping for the liquidity on the market

For this swap, Nexus Mutual chose the Chainlink oracle as their price checker, guaranteeing that they would receive no less than the minimum specified in the governance proposal.

Nexus Mutual Trade Breakdown

On July 10th, 2023, After a successful  [governance vote](https://app.aave.com/governance/proposal/?proposalId=267)  from Aave DAO, CoW Swap processed a large LP position trade for Aave using the exchange’s signature intent-based trading design and Milkman contract.

Since then, Aave completed another trade totaling $1,948,000 with the goal of  [treasury diversification](https://app.aave.com/governance/proposal/282/).

## 1st Trade Details

-   **Positive difference compared to direct deposit**: 1,918.72 units of B-80BAL-20WETH
-   **Positive difference due to slippage**: 556 units of B-80BAL-20WETH

## 2nd Trade Details

Aave DAO swapped DAI to USDC for treasury diversification purposes. This trade also occurred over two transactions ([Transaction 1](https://explorer.cow.fi/orders/0x03a16efc858c41dd476b8270ed7cdeac00718dd72902493e13c4ec4931a8543d944ea54ae648ceebbdc3e643e8a993a0c4e8dae564ca6b2a?tab=overview)) ([Transaction 2](https://explorer.cow.fi/orders/0xffa61ae864eeaa228ca19195887303d278bbd40f75a9c70493737eb3dbcd0280264fe3292fc2a05500d638093d88adbca487e36864ca6b31?tab=overview)).

-   **USD value of the trade**: $1,937,476
-   **Amount the DAO received**: 1,937,476 USDC
-   **Price Surplus**: $9,699.15

## Why CoW Swap?

CoW Swap’s solver competition ensured that Aave received the best possible execution price, even after announcing trade details publicly in a governance proposal ahead of time.

Compared to a direct deposit, CoW Swap provided several benefits for this trade:

1.  Protection from attack vectors caused by the delayed execution
2.  The minimum amount in a direct deposit proposal would have been uncertain, requiring a high slippage tolerance to successfully execute the trade, which in turn would expose the trade to MEV bots
3.  Use of the Milkman bot for protection against MEV, slippage, and re-entrancy risk

## Milkman

The CoW Grants Program-funded, and Yearn.fi-developed  [Milkman bot](https://github.com/cowprotocol/milkman-bot)  was critical to the Aave trade.

The Milkman bot ensures that trades execute for the real-time price or better by utilizing a price checker, such as a Uniswap v3 pool, Chainlink oracles, or a custom price checker. Instead of setting a slippage tolerance, DAOs can utilize Milkman to determine a maximum percentage deviation from the price checker, guaranteeing that their trade will finalize at a fair market price. Milkman also simplifies governance for trades as DAOs don’t have to define a fixed price re-vote if the market moves significantly.

For this swap, Aave DAO chose the Chainlink oracle as their price checker, guaranteeing that they would receive no less than the minimum specified in the governance proposal.
