Existing on-chain trading forces every user to act like their own solver. You choose the route, the pool, the slippage tolerance, and the execution strategy — all before the market has competed to give you a better outcome. This creates several problems:
  • Fragmented liquidity — Users must manually search across pools and aggregators.
  • MEV exposure — Public mempool transactions are vulnerable to frontrunning and sandwich attacks.
  • Poor protection — A badly chosen minimum output or slippage setting can leave money on the table.
  • Complex UX — New users face routing decisions they shouldn’t need to make.
Reiy flips this model: users describe the outcome they want, not the path to get there. The How Reiy Works page explains the full architecture — intents, off-chain solver competition, and certificate-verified on-chain settlement.
