As of my last knowledge update in January 2023, 1inch is a decentralized exchange (DEX) aggregator and liquidity protocol. It allows users to discover and trade on various decentralized exchanges to get the best possible rates for their trades. The 1inch platform sources liquidity from multiple DEXs and performs trades split across different liquidity pools to optimize for price and minimize slippage.

Here are some key features of 1inch:

1. DEX Aggregation: 1inch aggregates liquidity from various decentralized exchanges, providing users with the ability to access the best available rates for their trades.

2. Smart Contract Optimizations: The 1inch algorithm is designed to find the most efficient paths for executing trades, reducing slippage and maximizing returns for users.

3. Limit Orders: 1inch offers limit order functionality, allowing users to set specific price levels at which they want their orders to be executed.

4. Gas Fee Optimization: The platform aims to optimize gas fees by routing transactions through the most cost-effective paths.

5. DAO Governance: 1inch has a decentralized autonomous organization (DAO) that allows users to participate in the governance of the protocol.

Please note that developments in the decentralized finance (DeFi) space can occur rapidly, and it's recommended to check the latest information and updates from official sources for the most current details on 1inch or any other platform.
