Introduction to 1inch

1inch is a decentralized exchange (DEX) aggregator that sources liquidity from multiple exchanges to find the best prices for token swaps. By splitting orders across multiple DEXs and optimizing routing, 1inch typically provides better rates than trading on any single exchange.

Founded by Sergej Kunz and Anton Bukov (who famously discovered an arbitrage opportunity at a hackathon), 1inch has grown from a simple aggregator into a comprehensive DeFi platform with its own limit order protocol, liquidity protocol, and multi-chain presence.

The DEX Aggregation Problem

Fragmented Liquidity

DeFi challenge:

  • Many DEXs exist
  • Liquidity fragmented
  • Best price unclear
  • Manual comparison tedious

1inch Solution

Aggregation approach:

  • Check all major DEXs
  • Find optimal route
  • Split orders if beneficial
  • Execute atomically

Why It Matters

User benefits:

  • Better prices
  • Single interface
  • Gas optimization
  • Complexity abstracted

How 1inch Works
