Trezor Integrates 1inch Fusion for Gasless Crypto Swaps

Trezor has integrated 1inch Fusion into its Trezor Suite platform, enabling gasless and MEV-protected cryptocurrency swaps.

Trezor Users Gain Gasless Token Swaps with 1inch Fusion

The Trezor integration allows users to trade tokens across multiple blockchains—including Ethereum, Polygon, and Arbitrum—without needing native tokens to pay gas fees. Swaps are executed directly within Trezor Suite, leveraging 1inch Fusion’s liquidity aggregation and protection against front-running attacks.

In a release shared with Bitcoin.com News, key features include MEV attack prevention, cross-chain liquidity access, and hardware-level security. All transactions are signed offline via Trezor devices, ensuring private keys remain secure. The service is available for Trezor Model T, Safe 3, and Safe 5 users.

1inch Fusion eliminates gas fees by abstracting network costs, simplifying decentralized trading. It essentially uses a method called “meta-transactions.” Instead of users paying gas directly with native tokens like ether, the protocol bundles and routes trades through special resolvers—third-party entities that pay the gas fees upfront. The protocol also shields users from sandwich attacks, which exploit price slippage during transactions.

In a sandwich attack, a malicious trader detects your pending transaction and swiftly executes orders both ahead of and behind yours, artificially distorting the price. This sleight of hand forces you into a less favorable trade while pocketing the difference as profit. The protocol thwarts this trickery by obscuring trade timing, making it far more difficult for opportunists to identify—and exploit—your moves

According to the team, Trezor’s partnership with 1inch aligns with its focus on self-custody and security. The integration aims to streamline DeFi access while maintaining hardware wallet protections. “By removing the need for native gas tokens and protecting users from MEV attacks, Fusion delivers frictionless, secure token swaps directly within the Trezor ecosystem,” Danny Sanders, the CCO at Trezor, remarked.
