Ledger, the global leader in digital asset security for consumers and enterprises, integrated the Uniswap Trading API to offer decentralized, permissionless swaps directly inside Ledger Wallet.
By choosing Uniswap’s API, Ledger enables native support for swaps while maintaining its core principles of user control and security.
The challenge
Ledger Wallet is trusted by millions, and works seamlessly with Ledger signer devices to provide full control and secure self-custody of digital assets.
As swapping activity grew among its users, Ledger looked for a way to offer trusted, decentralized swap functionality natively inside the wallet. This would allow users to stay in the secure environment of their Ledger device without being redirected elsewhere.
Meeting this demand required Ledger to integrate a solution with access to deep liquidity, fully permissionless access and fast, consistent execution.
The solution
After evaluating options, Ledger chose the Uniswap Trading API. It provided a trusted, production-ready way to add decentralized swaps without having to deal with the complexity of gas estimates or building their own routing.
Uniswap’s deep liquidity, reliable performance, and alignment with Ledger’s commitment to user control made it the clear choice, supported by an API that is well-designed, easy to work with, and backed by a consistently responsive team.
The API also allowed Ledger to maintain its secure device-based signing flow, and the combination of clear documentation and hands-on support helped make implementation fast and smooth across engineering and product teams.
"Uniswap has been present since January 2025 within the Ledger Wallet App. Uniswap API has been built to offer the best possible and the simplest Swap experience to any Wallet user. Since Ledger has made the Uniswap Trading API available to Ledger Wallet users, the combination with Ledger's signers' clear signing on secure screen brings together simplicity, choice, fast transaction time and unique security." — Jean-Francois Rochet, EVP of Consumer Services at Ledger
The results
Uniswap has quickly become a popular swap option within Ledger Wallet. Users can access onchain liquidity while staying in Ledger’s secure signing environment.
The integration also gives Ledger a straightforward path to add support for more chains over time.
Why it matters
Ledger and Uniswap Labs share a commitment to secure, user-owned access to DeFi.
By connecting Ledger’s hardware-backed self-custody model with Uniswap’s liquidity infrastructure, the integration delivers a seamless decentralized swap experience within an environment users already trust.
