Case Study: Ledger achieves secure, seamless remote control of hardware crypto wallets with A.Team

Building a remote control app to interact with hardware crypto wallets

Ledger, a hardware crypto wallet company, needed a secure "remote control" for Ledger Live so users could interact with web3 services from their browser while still authorizing transactions on their hardware device. A.Team was engaged to build a browser extension companion app that would act as that remote control, enabling crypto signatures across any blockchain while maintaining the security of Ledger hardware.

A.Team delivered a browser extension with reliable, consistent communication to the desktop Ledger Live app that triggers approval messages on the Ledger device to authorize signatures. The solution lets investors access web3 services, synchronize accounts (the UI shows 6 accounts), and perform buy/swap/trade flows from the browser while keeping private keys on the hardware—demonstrating secure, seamless cross-chain interaction enabled by A.Team.
