The leading intents-based DEX aggregation protocol

MerCury Protocol leverages intents, batch auctions, and the largest solver network in DeFi to bring surplus-capturing, MEV-protected trades to users

How it works

MerCury Protocol hosts a continuous competition between solvers to find better prices and protect users from MEV

Intents

MerCury Protocol users sign an "intent to trade" message instead of directly executing orders on-chain (like on Uniswap). This lets solvers trade on behalf of the user.

Solvers

Professional third parties known as solvers find the most optimal trade path from a combination of public and private liquidity sources - finding better prices than most users could find on their own.

Batch Auctions

Solvers compete for the right to settle trades in batches, which give users additional MEV protection.

The solver that wins the batch auction is the solver that finds the most surplus - so they win when you win.

Going where others can't

Thanks to its unique architecture, MerCury Protocol can do things other DEXs can't

Advanced order types
Limit orders

Placing a limit order is like setting a trap for a price for your trade. MerCury Swap is the only DEX that offers surplus on limit orders - and one of the only DEXs that offers limit orders at all

Unique trading logic
Programmatic orders

Easily deploy conditional orders that trigger when specified on-chain conditions are met

Hooks

Add pre- and post- hooks to tie your trade to any other DeFi activity (bridging, staking, depositing, etc.)

Want to build a solver?

Solvers are the backbone of MerCury Protocol. In a nutshell, solvers are optimization algorithms that compete to find MerCury Protocol users the best possible settlements for their trade intents.

Advanced solver teams can earn hundreds of thousands of dollars per year by winning batch auctions frequently.
