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

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, laying the foundation for seamless swaps between SOL and over ten other blockchains already integrated with 1inch.

Why Solana?

The integration comes amid Solana’s standout performance in the blockchain space. According to Dune Analytics, Solana outpaced Ethereum in several key areas over the last three months:

$395 billion in DEX trading volume (vs. Ethereum’s $364 billion) 4.8 billion transactions processed (vs. Ethereum’s 1 billion) 224 million active addresses (vs. Ethereum’s 78 million)

Solana’s short block times and high throughput make it an ideal match for 1inch’s Fusion protocol, which introduces a novel intent-based trading mechanism. In this system, users define trading parameters while market makers — referred to as “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 tradable via 1inch. These tokens benefit from:

MEV (Miner Extractable Value) protection Aggregation across all available liquidity sources Open-source smart contracts, offering increased transparency compared to other DeFi platforms on Solana

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

What’s Next?

Looking ahead, cross-chain swap functionality between Solana and other networks supported by 1inch is expected to launch in the coming months. This capability will allow users to trade assets seamlessly across chains, addressing the fragmentation that has historically hindered DeFi growth.

“This integration is a leap toward dissolving the isolation of individual blockchains and constructing a unified multichain DeFi ecosystem,” 1inch stated.
As 1inch extends its reach into the high-speed Solana network, the move represents not just technical progress but a broader shift toward a more interconnected and user-friendly decentralized financial landscape.
