Integration Brings Fusion Protocol and MEV Protection to Solana Users

1inch, one of the leading decentralized exchange (DEX) aggregators, has officially launched on Solana, marking a major step forward in its goal of building a “unified multichain” decentralized finance (DeFi) ecosystem.

According to an April 28 press release, the integration allows users to trade over 1 million Solana-based tokens directly through the 1inch DApp, featuring:

• Maximal Extractable Value (MEV)-protected swaps

• Optimized trading rates

• Open-source smart contract infrastructure

The launch brings the 1inch Fusion protocol to Solana for the first time. Fusion enables users to define their ideal swap parameters, which are then executed via Dutch auction mechanisms by competing professional market makers, known as “resolvers.”

Combined with Solana’s ultra-fast block times, the setup is designed to deliver cheaper, faster, and more efficient trades compared to many other blockchain networks.

“Users may expect costs of less than one cent when executing swaps on Solana,” a 1inch representative told Cointelegraph.

Crosschain Swaps on the Horizon

Beyond enabling Solana-based swaps, 1inch revealed it is actively developing crosschain functionality, which will eventually allow users to swap assets between Solana and over 10 other blockchains already integrated into its ecosystem.

“At this stage, there is no fixed launch date,” the 1inch representative said.
“However, development is progressing well, and we expect the feature to go live in the coming months.”

The initial crosschain expansion will focus on the 10 blockchains currently supported by 1inch’s crosschain interoperability protocol, with the final list to be confirmed closer to launch.

Solana’s DeFi Momentum Outpaces Rivals

1inch’s expansion into Solana comes amid strong DeFi performance metrics for the network. Over the past three months, Solana has:

• Achieved 33% higher DEX volume ($539 billion) than rivals

• Handled 400% more transactions

• Hosted 180% more active addresses

The data, compiled by Dune Analytics, underscores Solana’s rapid adoption and growing status as a serious challenger to Ethereum in the DeFi space.

“Both Solana and Ethereum play critical roles in the evolving DeFi landscape,” the 1inch representative said, acknowledging Ethereum’s continued dominance in liquidity depth while praising Solana’s performance gains.

Developer Tools and Long-Term Interoperability Vision

Alongside the user-focused upgrades, 1inch’s integration also includes access to six APIs through the 1inch Developer Portal, allowing builders to create new DApps and DeFi services on top of 1inch-Solana infrastructure.

This move follows 1inch’s September 2024 white paper unveiling its intent-based, crosschain interoperability protocol, aimed at resolving crosschain fragmentation while preserving self-custody.

In September 2024, the project also launched Fusion+, a crosschain swap feature designed to let users move assets across chains seamlessly without relinquishing control of their wallets.

Final Thoughts: 1inch Positions Itself for a Multichain DeFi Future

1inch’s expansion onto Solana is strategic and timely, tapping into one of the fastest-growing ecosystems while preparing for a future where crosschain operability is essential.

As DeFi matures and multichain infrastructure becomes the norm, platforms that offer speed, low fees, and seamless crosschain experiences are likely to dominate — and with its Fusion protocol and upcoming crosschain capabilities, 1inch is betting it will be one of them.
