Solana–EVM swaps go trustless with native, bridge-free routing

1inch rolls out intent-based crosschain swaps to connect Solana and EVM networks with built-in MEV protection.

A half-decade into decentralized finance (DeFi), moving value across chains remains the industry’s most brittle link. Bridges and offchain messaging protocols have repeatedly exposed users to smart-contract exploits and operational lapses, while fractured liquidity and unfamiliar interfaces push many to centralized exchanges for simple transfers

Even when a swap clears, traders risk value leakage from maximal extractable value (MEV), where onchain actors can reorder or sandwich transactions. The upshot is a crosschain experience that feels slow, costly and precarious — exactly the opposite of what permissionless finance promises.

A bridge-free path for Solana and EVM

Against that backdrop, DeFi aggregator 1inch is positioning a new, native method for swapping directly between Solana and EVM networks — without bridges or third-party message relays

The company frames the launch as a milestone in “true trustless DeFi interoperability,” arguing that users and developers can now route assets on and off Solana with the same ease as single-chain swaps, and with MEV protection built in

The capability is live across the 1inch DApp, 1inch Wallet and via the Fusion+ API — which is available in the 1inch Developer Portal — aiming to dissolve Solana’s historical isolation from the broader Web3 liquidity pool and to simplify cross-ecosystem flows for apps and market makers.

Intent-based aggregation

1inch’s pitch rests on its aggregation stack and an “intent” model introduced with 1inch Fusion in late 2022. Rather than signing a swap that must execute at a fixed path, users sign the outcome they want — an intent that sets a minimum return, a time window and other presets. Professional traders known as “resolvers” then compete to fill that intent, drawing on both onchain and offchain liquidity sources

Source: 1inchPricing follows a Dutch-auction curve: the acceptable fill rate decays over time within the user’s parameters, encouraging faster, more efficient execution in liquid markets and graceful fallback when liquidity thins. A smart price curve accounts for gas and market depth to steer fills toward the best effective rate while keeping slippage in check.

Crucially, the architecture bakes in MEV protection. Because resolvers fill intents off the public mempool and settle them under predefined rules, the opportunity for front-running or sandwich attacks is constrained by design, aligning with 1inch’s broader goal of sealing common value-loss vectors in DeFi.

Crosschain and atomic swaps

The late-2024 Fusion+ upgrade extends that intent engine across chains. Instead of hopping through a conventional bridge, crosschain intents are matched and settled with atomic-swap logic — an “all-or-nothing” guarantee enforced by smart contracts

If any condition fails or a timelock expires, both legs unwind and funds return to their original owners. That trust-minimized setup removes reliance on custodial intermediaries and reduces exposure to the attack surface of message-passing bridges.

Source: 1inchFor users, the practical flow mirrors a normal swap: select a token on Solana, a token on an EVM chain (or vice versa) and confirm the intent. 1inch requires keeping the Swap tab open until the transaction is fully verified across both networks, reflecting the product’s focus on cryptographic verification rather than offchain assurances. Behind the scenes, resolvers compete to source the best route from a pooled, pan-Web3 liquidity set — one reason 1inch argues it can consistently surface competitive prices.

Why it matters for builders and everyday traders

Crosschain has long been the moment when users feel most vulnerable. By eliminating bridges and embedding MEV defenses, 1inch aims to make chain boundaries fade into the background. For wallets and DApps, the company provides a Fusion+ API to program direct Solana-EVM swaps into their flows while end-users can access the same capability through the 1inch DApp and self-custodial wallet

The broader 1inch suite — DEX aggregation for best-rate routing, a self-custodial wallet, a portfolio tracker, a developer portal and even a crypto debit card — rounds out the pitch as a single-platform toolkit for trading and managing assets across ecosystems.

While several teams are exploring intent layers and crosschain settlement, 1inch contends its approach stands apart on a few fronts: a mature aggregation algorithm tuned for best execution, a bridgeless design for surface-area reduction and MEV-aware execution as a default, not an add-on

By the numbers — and what’s next

The rollout lands on top of significant usage. According to 1inch, total trading volume across its platform has reached roughly $700 billion, with almost 25 million users executing about 200 million swaps. Those figures suggest a large installed base for seeding crosschain liquidity and a familiar interface for trying trustless Solana–EVM routing.

The roadmap centers on expanding interoperability and continuously refining execution quality. With a new approach to crosschain, expect more networks, deeper resolver participation and incremental UX improvement — particularly around verification, status clarity and failure handling.

If DeFi is to compete with centralized venues on simplicity and safety, the experience of moving value between chains must feel as reliable as paying with a card. The end state 1inch articulates is chain-agnostic finance: users trade, save and build without caring which ledger finalizes their transactions

Unifying Solana with EVM liquidity via atomic, MEV-aware intents moves the industry closer to that outcome — where interoperability becomes the default.
