[Stratos Lab] Workflow Orchestration with BPMN
We’re excited to introduce Stratos Lab and the two products we’re building for the Canton Network ecosystem.
A bit of background — we first entered the ecosystem through Canton Catalyst, where we built a privacy-preserving margin calculation tool. The idea was simple: counterparties could compute margin obligations on Canton without exposing the underlying positions.
That experience shaped a lot of how we think about the network today:
- privacy as the primitive,
- sub-transaction segregation as the unlock,
- and BPMN-style orchestration as the missing connective tissue between business intent and Daml execution.
Since then, we’ve been heads-down building two products.
Flow
Flow by Stratos Lab is our multi-destination workflow orchestration tool designed around BPMN and Daml permission design.
You sketch a process on a Camunda-compatible BPMN canvas, attach Signatories, Controllers, and Observers directly to workflow nodes, and Flow compiles each pool into:
- Daml contracts on Canton,
- plus the off-ledger dispatch layer needed to drive execution.
That dispatch layer can target:
- Daml Trigger,
- Cloudflare Workflows,
- Chainlink CRE,
- or custom worker runtimes.
The canvas is real-time collaborative, and includes a natural-language agent that generates a first-cut BPMN flow and Daml stub directly from plain-English descriptions.

Portal
Portal is our multichain wallet infrastructure anchored on Canton Network, built for gated DeFi applications.
Our thesis is that:
- DeFi access control,
- entitlements,
- counterparty checks,
- and jurisdictional gating
belong on a privacy-preserving permissioned layer, while settlement and execution can fan out across whichever chains the application ultimately uses.
Portal anchors identity and gating logic on Canton, while signing and execution operate across multiple chains through MPC-backed key management.
We had been exploring featured-app status, but following the recent changes to the requirements, we’ve decided to defer that track for now and focus on shipping both Portal and Flow to the broader ecosystem.
We’d love to connect with:
- validators,
- app providers,
- infrastructure teams,
- and builders across the Canton ecosystem.
Especially teams who:
- want a BPMN-first design surface for multi-party workflows,
- or are thinking about how to gate DeFi access without giving up multichain reach.
Happy to set up calls, demo Flow, or discuss architecture here.
