Following the latest reports, 1inch, a leading decentralized exchange (DEX) aggregator, has announced its integration with the Solana blockchain. This brings 1inch’s Fusion protocol to Solana, enabling users to execute secure token swaps with optimized rates and minimal fees. As 1inch expands to Solana, it allows for upcoming cross-chain swap functionality, further unifying major DeFi ecosystems.
Fusion Protocol Debuts on Solana
The integration introduces 1inch’s proprietary Fusion protocol to the Solana network. Fusion allows users to define their ideal swap parameters, which are then executed by professional market makers, known as “resolvers,” through Dutch auction mechanics. This system enhances swap execution by offering competitive pricing mechanisms and minimizing slippage.
Combined with Solana’s ultra-fast block times and low transaction fees, the Fusion protocol promises more efficient and seamless trading experiences. Users can now trade over 1 million Solana-based tokens directly through the 1inch decentralized application (DApp), benefiting from maximal extractable value (MEV)-protected swaps and open-source smart contract infrastructure.

Minimal Fees and Developer Tools
A 1inch representative reveals the cost-effectiveness of swaps on Solana, stating that users can expect transaction costs of less than one cent. This affordability is an advantage for traders seeking efficient and economical transactions.
Additionally, as 1inch expands to Solana, it includes access to six APIs through the 1inch Developer Portal, providing developers with tools to create new DApps and services on top of the 1inch-Solana infrastructure. These APIs encompass Swap API, Balance API, Token API, Spot Price API, Transaction Gateway API, and Gas Price API .
Cross-Chain Swap Functionality on the Horizon
Looking ahead, 1inch plans to roll out cross-chain swap functionality in the coming months. This feature aims to allow swaps between Solana and more than 10 other blockchains already supported by 1inch, including Ethereum, BNB Chain, Polygon, Avalanche, Fantom, Arbitrum, Optimism, Gnosis Chain, Base, and zkSync Era.
While there is no fixed launch date, development is progressing well, and the company expects the feature to go live in the near future. The cross-chain swaps will initially support the 10 blockchains already integrated into 1inch’s cross-chain swap ecosystem, with the final list to be confirmed closer to launch .

1inch’s expansion into Solana comes as the blockchain has outperformed Ethereum and layer-2 networks in several key DeFi metrics. Over the past three months, Solana posted a 33% higher DEX trading volume ($539 billion), handled 400% more transactions, and hosted 180% more active addresses than its rivals .
Conclusion
The integration of 1inch with Solana is a step toward a unified multichain DeFi ecosystem. By combining 1inch’s advanced aggregation and swap functionalities with Solana’s high-performance blockchain, users can expect enhanced trading experiences characterized by speed, efficiency, and cost-effectiveness. The forthcoming cross-chain swap functionality further promises to bridge liquidity across major blockchains, fostering greater interoperability and innovation within the DeFi space.
