Ledger has integrated the Uniswap (UNI) Trading API, enabling secure, permissionless swaps within Ledger Wallet, enhancing user control and access to onchain liquidity.
Ledger, renowned for its digital asset security solutions, has integrated the Uniswap (UNI) Trading API to enable secure, decentralized swaps directly within the Ledger Wallet. This strategic move pairs self-custody with robust onchain liquidity, according to Uniswap Labs.
Addressing User Demand
As the popularity of swapping activities grew among Ledger users, the company sought a way to incorporate trusted, decentralized swap functionality within its wallet. This would allow users to remain within the secure environment of their Ledger devices, avoiding the need for redirection to external platforms.
The challenge was to integrate a solution that provided deep liquidity, permissionless access, and consistent execution without compromising on security or user control.
Choosing Uniswap Trading API
After evaluating various options, Ledger selected the Uniswap Trading API for its reliable performance and alignment with Ledger's core principles. The API offered a production-ready solution for decentralized swaps, eliminating the complexities of gas estimates and routing, and was supported by a responsive team and comprehensive documentation.
This integration maintained Ledger’s secure device-based signing flow, ensuring a seamless experience for users. The API's clear design and support facilitated a swift and smooth implementation process.
Implementation and Impact
Since its introduction in January 2025, the Uniswap Trading API has become a popular option within the Ledger Wallet, allowing users to access onchain liquidity while staying secure. The integration also provides a straightforward path for Ledger to expand support to more blockchain networks in the future.
Jean-Francois Rochet, EVP of Consumer Services at Ledger, highlighted the synergy between Ledger's secure signing and Uniswap's liquidity infrastructure, emphasizing the enhanced simplicity, choice, and security for users.
Significance in the DeFi Space
The collaboration between Ledger and Uniswap Labs underscores a shared commitment to secure, user-owned access to decentralized finance (DeFi). By combining Ledger’s hardware-backed self-custody model with Uniswap’s liquidity infrastructure, the partnership delivers a seamless and trusted decentralized swap experience.
This integration represents a significant step in providing users with a more comprehensive and secure DeFi experience, leveraging the strengths of both Ledger's security and Uniswap's liquidity capabilities.
