1inch Launches Solana Integration, Paving the Way for Cross-Chain DeFi Expansion

Decentralized exchange aggregator 1inch has announced the launch of support for Solana, enabling users to perform on-chain swaps through its dApp and access six APIs via the 1inch Developer Portal.

The announcement was made during TOKEN2049 Dubai, signaling a major milestone for the platform’s cross-chain ambitions. This marks the first major deployment of the 1inch Fusion protocol on Solana, paving the way for seamless swaps between SOL and over ten other blockchains already integrated with 1inch.

Why Solana?

The integration comes as Solana showcases standout performance. According to Dune Analytics, Solana outpaced Ethereum in several key areas over the last three months:Solana’s short block times and high throughput make it an ideal match for the 1inch Fusion protocol, which introduces a novel intent-based trading mechanism. In this system, users define trading parameters, while market makers, termed “resolvers,” compete to fulfill orders via a Dutch auction process. This setup reduces slippage, boosts efficiency, and enhances liquidity aggregation.

Fusion Protocol: MEV Protection and Transparency

With the new integration, over 1 million Solana-based tokens are now easily accessible for trading through 1inch. These tokens benefit from the Fusion protocol’s unique properties, which include:optimal routing for best prices and fast execution.

Moreover, 1inch highlighted that its Solana implementation includes the most audited smart contracts in the ecosystem, further solidifying its commitment to security and trust.

What’s Next?

In the upcoming months, 1inch plans to introduce cross-chain swap functionality between Solana and other networks supported by 1inch. This capability will allow users to trade assets seamlessly across chains, facilitating the interconnection of major blockchains like Bitcoin, Ethereum, Optimism, Arbitrum, Polygon, and Fantom with Solana.

This initiative addresses the fragmentation that has historically encumbered the growth of decentralized finance (DeFi).

“This integration is a leap toward dissolving the isolation of individual blockchains and constructing a unified multichain DeFi ecosystem,” noted 1inch.

As 1inch expands its reach into the high-speed Solana network, the move represents not just technical progress but also a broader shift toward a more interconnected and user-friendly decentralized financial landscape.
