Project goals & our vision

Our primary objective was to build the foundational identity layer for the Canton ecosystem. We focused on three key goals:

GOAL 1SOLUTION 1

Build a single unified identification platform

Create a central hub for identity verification, allowing users to complete KYC once and use it everywhere in the network.

How we achieved it?

We implemented a one-time KYC process using Sumsub integration. Once a user is verified, a proof of their status is recorded on a Daml smart contract. This creates a single, tamper-proof credential with a consent-based sharing model, ensuring data is only shared after the user explicitly approves the request.
GOAL 2SOLUTION 2

Monetize protocol activity via rewards

Design the solution to leverage Canton Network's native incentive model, allowing the client to earn rewards based on interaction volume.

How we achieved it?

We structured the platform to align with the Canton Network’s native reward system – each utility-generating activity with the identity solution generates a Canton reward coupon. These coupons are a claimable right for participants to mint Canton Coin, effectively monetizing the protocol's activity and incentivizing usage.
GOAL 3SOLUTION 3

Accelerate ecosystem onboarding for businesses

Build the platform as a foundational service that new projects can easily adopt, lowering the technical barriers to entry.

How we achieved it?

We delivered a comprehensive API, allowing businesses to implement a compliant, enterprise-grade KYC solution with minimal effort and resources.

Delivery

The final product is a complete, multi-faceted platform that empowers every participant in the Canton network.

  • Users undergo KYC procedure once and can then immediately use any project's services.
  • Businesses, after connecting to the platform, can leverage the user pool that is interested in their project, and onboard customers in under 2 minutes.
  • The entire system's integrity is secured by two custom Daml smart contracts that automate verification and consent on the blockchain.

Our process

Screen design for the Starlink Energy case for different devices

Deep technical protocol research

Our process began with deep technical research to ensure we architected the best possible solution. From there, we followed a transparent and agile methodology.

Requirements & planning

We collaborated closely with the client and core team behind Canton to define precise requirements, map out all technical details, and establish a clear project roadmap.

Agile development & design

Working in sprints, our team designed the UI/UX and developed the platform's core components. We held regular demos at each stage to ensure alignment and incorporate feedback. Two distinct Daml smart contracts were developed to manage verification proofs and consent logic.

Integration & deployment

We integrated the platform with Sumsub, saving development time and operational cost for a client, and deployed the solution for production use.
