1inch is non-custodial, and all trades take place within one transaction from a user’s wallet on any of the supported blockchains and layer-2 networks. The technical structure of all 1inch protocols provides a high degree of security to users as well. For example, insecure liquidity sources can connect to the 1inch Aggregation Protocol without users risking the loss of funds. The protocol integrates security checks during every transaction to prevent any losses. As of July 2022, more than 240 liquidity sources are integrated into the 1inch Network. 1inch smart contracts got audited by leading audit teams in the industry such as OpenZeppelin, Consensys diligence, SlowMist, Haechi Labs, CoinFabrik, Certik, Hacken, Scott Bigelow, MixBytes, and Chainsulting.

In addition, to access to deepest liquidity from multiple sources across multiple blockchains, the 1inch Network offers users attractive prices and a high degree of security being the most audited project in DeFi. In late 2022, the Fusion mode was introduced, which enables users to swap tokens without paying any network fees and at the most favorable rates. In addition, Fusion mode offers users extra MEV protection. All swaps in Fusion mode are executed by resolvers – professional traders, who use the most sophisticated and efficient ways of protecting users’ swaps from MEV.

The 1inch Network was founded by [Sergej Kunz](https://coinmarketcap.com/alexandria/author/sergej-kunz) and [Anton Bukov](https://coinmarketcap.com/alexandria/people/anton-bukov) over the course of the ETHGlobal New York hackathon in May 2019. The two had earlier met during a live stream of Kunz’s YouTube channel (CryptoManiacs) and began entering hackathons together, winning a prize at a hackathon in Singapore, as well as two major awards from the ETHGlobal. Prior to 1inch, Sergej Kunz worked as a senior developer at product price aggregator Commerce Connector, coded at communication agency Herzog, led projects at Mimacom consultancy, and then worked full time at Porsche in both DevOps and cybersecurity. Anton Bukov had worked in software development since 2002 and in decentralized finance (DeFi) since 2017. Among other projects, his resume features gDAI.io and NEAR Protocol.

The 1inch Network unites decentralized protocols whose synergy enables the most lucrative, fastest, and protected operations in the DeFi space. The 1inch Network's first protocol is a decentralized exchange ([DEX](https://coinmarketcap.com/alexandria/glossary/decentralized-exchange-dex)) [aggregator](https://coinmarketcap.com/alexandria/article/what-are-dex-aggregators-a-deep-dive-by-1inch) solution that searches deals across multiple liquidity sources, offering users better rates than any individual exchange. The 1inch Aggregation Protocol incorporates the Pathfinder algorithm for finding the best paths across over 400+ liquidity sources on 12 chains: Ethereum, BNB Chain, Polygon, Avalanche, Optimism, Arbitrum, Fantom, Gnosis Chain, Klaytn, Aurora, zkSync and Base. In just over two years the 1inch DEX aggregator has reached 1M users and surpassed $150B in overall volume on the Ethereum network alone. The 1inch Limit Order Protocol facilitates the most innovative and flexible limit order swap opportunities in DeFi. The protocol’s features, such as dynamic pricing, conditional orders, and extra RFQ support, power various implementations, including stop-loss and trailing stop orders, as well as auctions. The [1inch Wallet](https://apps.apple.com/us/app/1inch-defi-wallet/id1546049391) is a multichain mobile platform that provides an easy-to-navigate interface with secure storing, transaction, and staking capabilities. This versatile wallet was built from the ground up to streamline interacting with 1inch’s features. The 1INCH token is the governance and utility token of the 1inch Network. 1INCH holders can stake their tokens to participate in the 1inch Network's [DAO](https://coinmarketcap.com/alexandria/glossary/decentralized-autonomous-organizations-dao) governance, including the 1inch DAO Treasury management. Also, holders can choose resolvers and earn a part of their fees. With the 1inch Fusion, users can stake 1INCH tokens to receive Unicorn Power (UP), then subsequently delegate their UP to any 1inch Fusion Resolver to start receiving rewards from them. When staking, there is the option to set a custom or preset lock period. User’s st1INCH tokens cannot be unstaked/withdrawn without penalty until the designated lock period expires. In December 2020, 1inch raised $12 million in Series A funding, led by Pantera Capital, with others including ParaFi Capital, Blockchain Capital, Nima Capital, and Spartan Group. The funding round was conducted through a SAFT (simple agreement for future tokens) sale. In December 2021, 1inch has closed a $175 million Series B round, led by Amber Group. Among about 50 investors that participated in the funding event are Jane Street, VanEck, Fenbushi Capital, Alameda Research, Celsius, Nexo, Tribe Capital and Gemini Frontier Fund.
