1inch Network is a decentralized finance (DeFi) infrastructure provider best known for its DEX Aggregation Protocol. The protocol scans liquidity from hundreds of decentralized exchanges (DEXs) across multiple blockchains to identify trade routes. By utilizing the Pathfinder algorithm—which received an efficiency upgrade in June 2025—the network splits single trades across various liquidity pools to optimize execution rates and minimize gas costs.

The network has expanded beyond simple aggregation into a comprehensive cross-chain and liquidity infrastructure layer:

Aqua Protocol (November 2025): 1inch launched Aqua, a shared liquidity layer designed to improve capital efficiency. Aqua allows liquidity providers to utilize their assets across multiple DeFi strategies simultaneously, using an intent-based architecture to "pull and return" liquidity as needed for specific trades.

Solana Cross-Chain Swaps (August 2025): The network deployed Fusion+, enabling native, cross-chain swaps between Solana and over 12 EVM-compatible networks (such as Ethereum, Arbitrum, and Base). Unlike traditional bridges, this system uses atomic swaps, ensuring users retain self-custody throughout the cross-chain process.

RWA Integration (September 2025): The 1inch Swap API was updated to support Real World Assets (RWAs). Through partnerships with issuers like Ondo Finance, users can now swap native crypto assets for tokenized treasury bills and other regulated securities directly within the 1inch interface (subject to jurisdictional eligibility). Cryptoassets linked to real-world assets depend on off-chain legal and custodial structures. These arrangements may not be legally enforceable in all jurisdictions, and token holders may not have direct ownership or redemption rights over the underlying asset.

1inch Fusion: A gasless trading mode where professional market makers ("Resolvers") fill orders. This is designed to reduce exposure to Maximum Extractable Value (MEV) attacks, such as front-running, by settling trades without the user paying network gas fees directly.

1inch Wallet & Portfolio: A self-custodial mobile wallet that includes a comprehensive portfolio tracker. It aggregates data from multiple chains to provide real-time PnL analysis and asset tracking.

1inch Card: A crypto-debit card solution that allows users to spend their crypto assets at traditional merchants, utilizing the 1inch swap engine for backend conversion.

The 1INCH token is the governance and utility asset of the ecosystem:

DAO Governance: 1INCH holders vote on key protocol parameters, including the "Swap Surplus" distribution and the allocation of the DAO Treasury.

Unicorn Power (Staking): Users can stake 1INCH to receive "Unicorn Power," a delegated voting power used to participate in governance and to delegate to Fusion Resolvers.

Token Type: Governance & Utility (ERC-20, BEP-20)

Total Supply: Capped at 1.5 Billion 1INCH

Supported Networks: Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Solana, Base, zkSync, and others.
