Overview

Planbok Organizational Wallets are enterprise-grade MPC wallets designed for businesses, treasuries, and DAO operational funds. They provide high-stakes security with granular organizational controls.

Key Features

• Institutional 2-of-2 MPC: Master private keys are split between two secure MPC nodes managed by Planbok. For maximum security, the Node 1 share is blinded by an organization-managed secret when trustless mode is enabled.
• Trustless Mode Support: Organizations can contribute high-entropy via an "Organization Secret" during registration. This ensures Planbok is cryptographically unable to sign without the secret provided by the client.
• Wallet Export & Portability: Organization Owners can export their private keys to use in external systems. Note: This feature is exclusive to Trustless MPC wallets as it requires the organization-managed secret to reconstruct the full key.

Security Model

Planbok Organizational Wallets utilize a 2-of-2 MPC framework with two distinct security tiers:

Standard MPC

Both key shares are generated and managed within Planbok's globally distributed infrastructure. This provides high availability and resilience against single-node failures while maintaining institutional-grade security protocols.

Trustless MPC (Organization Secret)

For organizations requiring a cryptographic boundary, Trustless Mode uses a client-provided "Organization Secret" during key generation:

1. Node 1 Share: Blinded by the Organization Secret. Planbok holds the blinded share but cannot unwrap it.
2. Node 2 Share: Managed by Planbok's secure infrastructure.

This ensures that transactions can only be signed when the organization provides the secret during the signing request, preventing any unilateral action by Planbok. This model also enables full key export, as the organization-managed secret is the final piece required to reconstruct the master private keys for external use.
