DEX Aggregators
1inch, Jupiter, CoW Protocol — aggregators finding best price across all DEXes.
DEX aggregators are protocols scanning multiple DEXes and finding optimal exchange routes — giving users better prices than using a single DEX directly.
How they work:
•Scan: Uniswap, Curve, Balancer, SushiSwap...
•Calculate optimal split path (path routing)
•Part of swap goes through Uniswap, part through Curve, etc.
•Minimize slippage and gas
Main aggregators:
1inch (Ethereum/EVM):
•#1 DEX aggregator by volume
•Fusion Mode — intents-based, no gas for user
•1INCH token for governance
•API available for developers
Cow Protocol / CoW Swap:
•Batch auction mechanism
•Order matching (coincidence of wants)
•MEV protection — don't pay for frontrunning
•Gasless orders
Paraswap:
•Multi-chain aggregator
•PSP token governance + fee share
Jupiter (Solana):
•#1 Solana DEX aggregator
•Scans all Solana DEXes
•Limit orders, DCA feature
•JUP token
OpenOcean (Multi-chain):
•Supports 30+ chains
•Includes CEX price comparison
Why use aggregator:
•Better price than direct DEX (typically)
•Slippage protection
•Gas optimization
•Single UI for all DEXes
