Nexus Mutual, a DeFi insurance protocol, has exchanged 14,390 ETH (worth $27.3 million) from its "safety insurance module" for Rocket Pool's rETH liquid staking token using the CoW Swap DEX aggregator. This is one of the largest on-chain swaps ever made by Nexus Mutual as part of its diversification strategy. The investment committee recommended reallocating funds from its insurance module to liquid staked ether, resulting in the decision to invest in rocket ether (rETH). Nexus Mutual chose CoW Swap as its preferred DEX aggregator due to its price-matching capabilities, protection against maximal extractable value (MEV), and ability to handle substantial volumes without significant slippage.
