概要
SIPO DRepレビュー支援用の日本語作業訳です。正式な内容はHydra Voting上の英語原文を参照してください。
VacuumLabsのHardware Wallet Maintenance 2026は、CardanoのLedger/Trezor対応、cardano-hw-cli、hardware wallet interoperability libraries、エコシステム開発者支援、vendor-required auditsを12か月継続保守する提案です。予算は1,310,960 ADAで、compatibility updates/release engineering 845,208 ADA、incident response/developer support 281,736 ADA、external audits 145,833 ADAを含みます。SIPOとしては、hardware walletはCardanoの安全なアクセス層であり、Pillar 1/2の公共インフラとして重要だと評価します。一方で、Ledger Technologies SASのLedger公式提案群との役割分担、過去のLedger App Rewriteの成果、TrezorとLedgerの責任範囲、T&M上限の時間単価・未使用返還、監査reserveの発動条件、SLA/priority、公開compatibility matrix、Treasury保護を確認する必要があります。

*Why now: Cardano protocol evolution, vendor firmware and app release cycles, and growing wallet and dApp integration demand continue to create compatibility risk on this security-critical access layer. Funding continuity in 2026 is less costly and less disruptive than waiting for breakage to accumulate and reacting only after users or integrators lose access.* *Cardano’s hardware-wallet stack must be maintained continuously or users and integrators lose secure access when Cardano, Ledger, or Trezor introduce breaking changes. This proposal requests 12 months of funding for production maintenance of Cardano hardware-wallet support: 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, and vendor-required product or security audits where firmware or app changes trigger them.* *This is a continuity proposal for an already-proven Cardano access layer, not a request to build a new wallet product; scope is limited to compatibility, security, supporting libraries/tooling, release support, and vendor-required audit work needed to keep supported hardware-wallet flows operational. This proposal is limited to hardware-wallet compatibility, tooling, and vendor-required assurance, and does not duplicate broader core-node, ledger, or general infrastructure maintenance budgets.* *The value to Cardano is continuity: users retain secure signing,builders avoid broken integrations, protocol and vendor changes do not strand hardware-wallet users, and newer utility layers can rely on a maintained hardware-wallet path. The proposal aligns with Cardano’s strategy around security, interoperability, developer experience, and adoption,and it will be delivered with clear milestones,evidence,and transparent capped T&M reporting so DReps can verify value as it is produced.*
