Uniswap Labs, the developers of the decentralized finance (DeFi) protocol Uniswap, and Ledger, a crypto hardware wallet provider, have announced a new integration to improve DeFi accessibility.
The partnership will enable Uniswap’s Trading API to be integrated with the Ledger Live crypto asset management app.
The integration will allow users to swap tokens directly within Ledger Live while maintaining control of their assets through their Ledger hardware wallet.
Mary-Catherine Lader, chief operating officer of Uniswap Labs, told Cointelegraph that the team’s integration is part of the mission “to unlock value through universal exchange” and simplify the self-custody user experience.
Clear signing directly from the DApp
Ian Rogers, chief experience officer and board member of Ledger, told Cointelegraph about the clear signing feature supported by the Uniswap API on Ledger Live.
“Clear signing is the only secure way users should be authorizing transactions,” he said. “If it’s unverifiable, it’s unreliable.”
With clear signing, transaction details are human-readable, allowing users to comprehend precisely what they’re authorizing — removing the “need for blind-signing permissions” or third-party wallet APIs, Rogers said.
The integration eliminates the need for hot wallets and intermediaries, allowing users to swap on Uniswap “directly from Ledger to the DApp,” he added. 
Primary use case and future plans
Initially supporting the Ethereum network, the integration focuses on token swapping as the primary use case, such as exchanging Ether (ETH) for stablecoins directly from self-custody.
Rogers highlighted that this partnership aligns with the shared vision of providing secure, trusted platforms for digital asset management.
“Long-term, more DeFi users are moving closer to universal exchange, all while maintaining self-custody,” Rogers said.
Uniswap Wallet flagged for vulnerability
On Jan. 13, ScaleBit, a subsidiary of security auditor BitsLab, flagged a vulnerability on the Uniswap Wallet app that could potentially compromise “all stored assets” in the decentralized exchange’s (DEXs) Web3 wallets.
The suspected flaw could enable attackers with physical access to a user’s device “to bypass the wallet’s authentication mechanism” and directly retrieve the “seed phrase” stored on the device.
Uniswap has yet to respond to the allegations, and Cointelegraph could not independently verify the vulnerability at the time of publication.
