About the project

The Supplier shall provide twelve (12) months of production maintenance for Cardano hardware-wallet support. This is a continuity engagement for an existing, proven access layer, not the build of a new wallet product.

The Services comprise Ledger and Trezor compatibility updates, maintenance of supporting interoperability libraries and cardano-hw-cli, developer support for ecosystem integrators, support for integration paths involving externally maintained components where shared hardware-wallet flows intersect, release and test work, incident response for high-priority compatibility and signing issues, and vendor-required product or security audits (including Ledger-certified audits) where firmware or app changes trigger them.
