Transferring value across blockchains has long been one of the most fragile parts of decentralized finance. Bridges and messaging systems often expose users to risks of hacks, code errors, and complex processes. Liquidity remains fragmented across multiple platforms, pushing many traders back to centralized exchanges just to complete basic transfers. Even when trades succeed, users can still lose money to MEV (Maximal Extractable Value), where transactions are reordered or manipulated for profit.
To solve these issues, 1inch has launched a bridge-free system that enables direct swaps between Solana and EVM chains. By removing bridges and integrating built-in protection against MEV, the goal is to make cross-chain trading safer, easier, and closer to the original vision of decentralized finance.
How It Works
Instead of relying on risky intermediaries, the system is built on intent-driven swaps. Users specify the outcome they want — such as the number of tokens expected and a time window for execution — and professional traders, known as resolvers, compete to fulfill the request. Prices adjust step by step over time, ensuring trades remain fair during both high- and low-volume market conditions.
Another key improvement is how trades are processed. They do not sit in public mempools, where others can front-run or exploit them. Instead, swaps follow fixed, transparent rules that all participants must respect. This significantly reduces the risks of strategies like frontrunning and sandwich attacks, making trades more reliable.
Fusion+ Upgrade
With its Fusion+ upgrade, 1inch has extended this mechanism across chains. Solana and EVM tokens can now be swapped directly using atomic logic, guaranteeing an “all-or-nothing” outcome. If any condition fails, the trade is canceled and funds are safely returned to the user, eliminating the risks typically associated with bridging.
For traders, the process feels no different from a standard swap: select a token on Solana, choose a token on an EVM chain, and confirm the trade. Developers can integrate the feature through the Fusion+ API, while everyday users can access it directly in the 1inch app and wallet. By combining MEV protection with bridgeless swaps in a familiar interface, barriers are lowered for both communities.
Scale and Vision
1inch already supports significant activity, having processed about $700 billion in trading volume across 25 million users and nearly 200 million successful swaps. This strong base of liquidity could help Solana–EVM swaps quickly gain traction.
The company’s broader vision is chain-agnostic trading, where blockchains fade into the background and users transact as easily as making a card payment. By connecting Solana and EVM liquidity pools in a trustless, bridge-free way, 1inch has taken another step toward making decentralized finance more unified, simple, and secure.
