Post-quantum wallets

Wallet software for transaction signing, encrypted wallet-file protection, recovery, and integration with post-quantum blockchain and custody systems.

Wallet scope

Key use and recovery are designed together.

The wallet layer controls how a transaction is assembled, approved, signed, submitted, and recovered. It can operate with protected software keys or route key operations to an HSM.

Recovery material can be separated using Shamir-based shares so the deployment does not depend on one complete recovery file or one operator.

Transaction workflow

Wallet policy defines the full path from an application request to a signed network transaction.

  • Transaction construction and network binding
  • Approval policy before signing
  • Submission, status tracking, and receipt verification

Post-quantum signing

The wallet can use post-quantum signature profiles supported by the connected blockchain and custody environment.

  • ML-DSA signing for compatible network profiles
  • Algorithm and key profile selected per deployment
  • Software or HSM-backed signing boundary

Encrypted wallet files

Wallet material is stored in an encrypted format with recovery designed as a separate operational process.

  • Encrypted wallet-file protection
  • Shamir-based splitting of recovery material
  • Configurable recovery threshold and share custody

Custody integration

Higher-assurance deployments can keep sensitive key operations inside the ATL PCIe HSM and expose only the required wallet operation to applications.

  • Policy-controlled key generation and signing
  • Application integration through a defined service boundary
  • Recovery, backup, and operator roles documented with the deployment
Project discussion

Define the requirement and deployment boundary.

ATL can scope this area as a focused component, an integration, or part of a complete engineering program.
