Decentralised finance aggregator 1inch has introduced a new system for crosschain swaps between Solana and EVM-compatible networks, removing the need for bridges and embedding protection against maximal extractable value (MEV). The launch is positioned as a milestone in creating a safer and more seamless decentralised trading experience.

The Problem with Crosschain Transfers

More than five years into decentralised finance, moving assets between blockchains remains one of the industry’s weakest points. Bridges and offchain messaging protocols have repeatedly been targeted by exploits and operational failures, causing heavy losses. Fragmented liquidity and complicated interfaces also push many users towards centralised exchanges for simple transactions.

Even when trades succeed, users often face value leakage from MEV attacks, where onchain actors manipulate transaction ordering. These risks have made crosschain activity feel slow, costly and insecure the opposite of what decentralised finance promises.

A Native Path Between Solana and EVM Networks
Against this backdrop, 1inch has launched a bridge-free method for direct swaps between Solana and 12 EVM chains. Instead of depending on custodial intermediaries or third-party relays, the system uses smart contracts and cryptographic guarantees.

The company describes the launch as “true trustless DeFi interoperability,” claiming that users can now move assets between Solana and EVM networks with the same simplicity as single-chain swaps. The feature is available through the 1inch DApp, the 1inch Wallet and the Fusion+ API, which is accessible via the 1inch Developer Portal.

Intent-Based Aggregation and MEV Protection
The new capability builds on 1inch Fusion, introduced in late 2022, which allows users to set trading “intents” rather than fixed paths. Traders define the outcome they want, such as a minimum return and time window, and professional resolvers compete to fulfil those requests. Pricing follows a Dutch auction, where acceptable rates decline over time, encouraging faster and more efficient execution.

Crucially, this architecture also limits MEV risks. Because intents are filled off the public mempool and settled under strict rules, opportunities for front-running or sandwich attacks are significantly reduced. This makes MEV defence a default feature rather than an optional add-on.

Atomic Settlement Across Chains
The Fusion+ upgrade, rolled out in late 2024, extended this intent-based model across multiple chains. Crosschain swaps now operate with atomic logic, guaranteeing an “all-or-nothing” outcome. If any condition fails, transactions are reversed and funds are safely returned.

For end-users, the process mirrors a normal token swap: select a token on Solana, choose a token on an EVM network and confirm the intent. The platform requires users to keep the swap tab open until final verification, underlining the reliance on cryptographic proof rather than offchain assurances.

Why It Matters for Traders and Builders
Crosschain activity has long been the point where users feel most exposed to risk. By removing bridges and embedding MEV protection, 1inch aims to make these boundaries effectively invisible. Developers can also integrate direct Solana–EVM swaps into their applications via the Fusion+ API, while individual traders can access the same capability through 1inch’s wallet and DApp.

The wider 1inch ecosystem already includes decentralised exchange aggregation, a self-custodial wallet, portfolio tracking tools, a developer portal and even a crypto debit card, positioning the platform as a comprehensive hub for asset management across chains.

Scale and Next Steps
The new feature builds on a large base of existing activity. According to company data, 1inch has processed almost $700 billion in trading volume, with nearly 25 million users completing around 200 million swaps. This established user base provides a foundation for expanding crosschain liquidity.

Looking forward, the company plans to add more networks, increase resolver participation and improve user experience around verification and error handling. The long-term goal is to make crosschain transactions as simple and reliable as paying with a card, moving towards a chain-agnostic financial system where the underlying ledger becomes irrelevant to end-users.

By linking Solana with EVM liquidity through atomic, MEV-aware intents, 1inch is pushing DeFi closer to that future of seamless and secure interoperability.
