Suggest the best decentralized exchange (DEX) for privacy and security?

Since I trade crypto almost every week, I can't bear the wallet fees so asking for a good exchange with privacy and security? Seen many exchanges holding funds including binance.

For privacy and security, THORChain (RUNE) is ideal for cross-chain swaps without KYC, while Railgun offers ZK-SNARK-powered private transactions on Ethereum and Layer 2s. CowSwap (Gnosis) also protects against MEV attacks by using batch auctions for anonymous, gas-efficient trades.
