42 secure applications brought to go-live on Ledger hardware wallets

The challenge

Ledger hardware wallets protect their users’ cryptographic assets. Every third-party service that wants to run on these devices — wallets, exchanges, DeFi protocols, NFT platforms — needs a dedicated, security-reviewed device application.

What we did

Our role

Every application published for Ledger devices goes through an external security audit before go-live. Over five years, Blooo has taken 42 applications to go-live across 5 device types, building security into each one from design, and none of these audits found a flaw (Kudelski Security, Quarkslab).

Working closely with Ledger, Blooo helps strengthen the security of digital assets and the trust their users place in them.

How we work

• Integrate: security is built in from the design of each application, with the constraints of the devices’ secure chip.
• Deploy: each application goes through acceptance testing and the external security audit before go-live.
• Watch: Blooo continuously tracks emerging threats and new attack methods, so that each go-live remains resilient against new vulnerabilities.

Blooo and Ledger share the same goal: a digital environment where users can rely on cryptographic technologies with confidence, with solutions that meet the highest standards of security and performance.

These are the Integrate and Deploy activities of Trusted Integration: delivering security through to go-live, and proving that it works, here through external audits.
