Trezor Has Officially Integrated 1inch Fusion

Trezor has officially integrated 1inch Fusion into its Trezor Suite, giving users a new way to swap cryptocurrencies without needing native gas tokens.

Trezor has officially integrated 1inch Fusion into its Trezor Suite, enabling users to swap cryptocurrencies without needing native gas tokens. This collaboration marks a significant step in simplifying and improving the security and usability of decentralized finance (DeFi).

While hardware wallets like Trezor are renowned for their security, managing gas tokens for different chains can be a common pain point for users. However, thanks to a partnership with 1inch Network, Trezor Suite will now allow users to perform token swaps across various blockchains—including Ethereum, Polygon, and Arbitrum—using only ETH to cover gas fees.

This integration introduces meta-transactions, a core technology that enables the system. Unlike typical transactions requiring users to pay gas fees in ETH or MATIC, the 1inch Fusion system routes transactions through resolvers, third-party actors who cover gas fees on the user’s behalf. In practice, users can execute a swap even if their wallet doesn’t contain native tokens to fund the transaction.

“We are excited to announce the integration of 1inch Fusion into Trezor Suite, offering our users a seamless and gasless way to swap tokens on various chains,” said Tomas "Toto" Votava, CTO of Trezor. “This partnership aligns perfectly with Trezor's broader focus on decentralization and user autonomy.”

One of the standout advantages of 1inch Fusion are its strong defenses against MEV (Miner Extractable Value) attacks, particularly sandwich attacks. These types of manipulation tactics are commonly used by bots and traders monitoring blockchain activity in search of pending transactions.

When a pending transaction is detected, a malicious actor can place one order before and one order after the victim’s transaction, thereby manipulating the market to their advantage. This results in the victim receiving a worse price, while the attacker profits from the engineered slippage. Because 1inch hides the timing and type of trades, it’s difficult for attackers to target and take advantage of them. The risk of manipulation is therefore significantly lowered.

The partnership with 1inch allows Trezor to expand the capabilities of its hardware wallet, already a preferred choice for those seeking maximum security in self-custody solutions. As the threat of phishing schemes and exploits targeting smart contracts increases, the importance of securing private keys and transactions is paramount.

Available for users of the Trezor Model T as well as the newer Safe 3 and Safe 5 devices, this update provides deeper integration with the DeFi ecosystem. As the leading hardware wallet, Trezor is known for its broad compatibility, further increasing accessibility to decentralized finance.

In a move that optimizes the user experience, Trezor will handle the technicalities of gasless transactions and integration with the 1inch Fusion protocol. Users can simply select the tokens they wish to swap and the amounts, and the Trezor Suite will execute the transaction in the background.

This partnership also highlights Trezor’s commitment to decentralization and user autonomy. With increasing numbers of users turning away from centralized exchanges and seeking direct access to DeFi services, having such services accessible within a secure hardware environment is becoming increasingly crucial.

The partnership with 1inch will enable users to perform token swaps across various blockchains using only ETH to cover gas fees. This eliminates the need for users to manage gas tokens for each chain, a common pain point in decentralized finance.

“We are thrilled to be partnering with Trezor to bring the benefits of 1inch Fusion to their users,” said Erich, the spokesperson for 1inch Network. “We believe that this integration will further enhance the Trezor experience by providing a simple yet powerful way to access and use DeFi.”

The integration of 1inch Fusion into Trezor Suite lessens the burden on users to learn the intricacies of gasless transactions or external dApps. Instead, they can focus on what matters most: managing their crypto assets seamlessly and securely.
