LeCoffre
A B2B2C notary certification SaaS built for sensitive document exchanges. Its interface aligns notary rigor requirements with the clarity their clients need.
Context
Simple, secure notary management
The platform centralizes and automates sensitive document collection. From their workspace, the notary reviews every document before securing the final file via blockchain anchoring.
On the client side, a guided workflow allows users to submit credentials and track file status autonomously.

Problem
Client clarity, notary control
Notarial document collection traditionally suffers from manual follow-ups, scattered files, and a lack of formal tracking. Faced with this complexity, designing a single shared portal would have required too many compromises.
Notaries demand high data density and total control, while clients require absolute clarity. Merging these asymmetric needs would have inevitably degraded the experience for one side or the other.
Solution
Three spaces for a single file
Three distinct spaces rely on a single source of truth, enabling the notary to manage, the client to submit, and the administration to supervise access.
This separation guarantees strict functional isolation. By eliminating broad compromises, each environment is tailored to its user’s priorities without ever degrading the experience for others.
Decisions
Simplifying through design choices
Separated spaces
The notary gets a data-dense view built for expertise, while the client benefits from a clean, distraction-free flow.
Progressive statuses
A visual pipeline replaces vague states with clear milestones, cutting down on manual client follow-ups.
Embedded blockchain
Blockchain anchoring integrates directly into the notary’s workflow, turning into a seamless action with instant visual feedback.
Notary workspace
Centralizing file management
The notary workspace centralizes the entire lifecycle of the file, from document requests to final certification. Built as the platform’s most data-dense environment, it enables one-click document validation and blockchain anchoring.
Management relies on a dynamic status system (empty, in progress, completed, action required, validated, anchored) reflecting the exact status of the file in real time.

Client workspace
Streamlining the interface to guide submission
The client environment eliminates cognitive load to focus solely on the required action: knowing which document to submit and where, without the complexity of the management system.
Following secure identity verification, a guided flow takes over. The interface clearly separates validated documents from those still requested by the notary office, offering immediate clarity on pending tasks.

Admin workspace
Vote-based governance
The admin workspace centralizes control across notary offices using three distinct permission tiers, designed for granular responsibility segmentation.
To protect sensitive data, the Super-Admin role incorporates mandatory voting. This design decision ensures that no critical updates to ecosystem permissions can be unilaterally approved by a single user.

Impact
Zero onboarding, zero follow-ups
The interface eliminates adoption friction for users with asymmetric workflows. By isolating workspaces, every stakeholder gets an environment tailored to their operational goals, free of visual noise.
For notary offices
Zero manual follow-ups lost in email threads. The interface centralizes real-time case tracking, provides full visibility, and enables one-click reminders or certifications.
For clients
Full autonomy from day one. Secure identity verification eliminates authentication friction, while the guided flow specifies required documents and notifies the client at every step.
