Decentralized exchange (DEX) aggregators are platforms that search multiple decentralized exchanges to find the best prices for cryptocurrency trades. They aggregate liquidity from various DEX platforms like Uniswap and Balancer, routing trades through the exchanges offering the best deals. Advanced intent-based DEX aggregators like CoW Swap go a step further by delegating trade execution to third-party solvers who can provide additional liquidity sources. DEX aggregators offer benefits such as better pricing, convenience, reduced price impact, and protection against miner extractable value (MEV). While 1inch is the most popular DEX aggregator by market share, CoW Swap is a leading innovator in the intent-based aggregator space, providing comprehensive trade protection and enabling price optimizations.

OnChainDen has integrated the CoW Swap Widget into their Safe app, allowing users to seamlessly swap tokens directly from the Safe user interface. This integration batches approvals and decodes CoW Swap data for signers, enabling them to verify transactions with a single signature. Users can benefit from MEV-protected swaps, lowest prices, and advanced order types like limit orders and TWAPs. The integration aims to reduce development costs and time-to-market for building DEX Safe apps while incorporating CoW Protocol's innovations.
