The initial protocol of the 1inch Network is a DEX aggregator solution that searches deals across multiple liquidity sources, offering users better rates than any individual exchange. This protocol incorporates the Pathfinder algorithm which finds the best paths among different markets over 50+ liquidity sources on Ethereum, 20+ liquidity sources on Binance Smart Chain and 7+ liquidity sources on Polygon. In less than two years the 1inch DEX aggregator surpassed $40B in overall volume. The 1inch Aggregation Protocol facilitates cost-efficient and secure swap transactions across multiple liquidity sources. The 1inch Liquidity Protocol is a next-generation automated market maker that protects users from front-running attacks and offers attractive opportunities to liquidity providers.
