Deep Canton expertise
Our engineers have production deployments on Canton Network. We understand PQS, Daml template semantics, participant node architecture, and the operational edge cases that only surface under real load.

Outer Sunset is building the operational layer Canton needs — one critical workflow at a time.
The problem
Canton is production-ready. The operational stack isn't.
Running a Canton Network participant means managing real financial obligations — validator rewards, domain fees, delegation flows, period-end accounting. Most operators are handling this with spreadsheets, manual reconciliation, and bespoke scripts. That works until it doesn't. Outer Sunset builds the infrastructure that makes Canton operations reliable, auditable, and scalable from the first month.
Products
Purpose-built for the Canton ecosystem.
The finance close stack for Canton validators and apps.
Ingests your transaction stream via PQS, generates double-entry journal entries, manages a structured month-end close with maker-checker controls, and commits a tamper-evident rollup attestation on-ledger at period end. Built for the finance operator who needs to close the books — and prove it.

Why Outer Sunset
We build where Canton actually runs.
Most tooling for blockchain networks is built by people who understand the protocol. We understand the protocol and the operational reality of running enterprise infrastructure on top of it.
Enterprise-grade by default
Maker-checker controls. Immutable on-ledger attestations. Versioned configuration with signed changelogs. Audit packages an external auditor can verify without touching a live system. We build for environments where correctness is not optional.
Narrow scope, deep execution
We don't try to solve every problem in the Canton ecosystem. We identify the workflows that matter most to enterprise operators and build them to a standard that holds up under scrutiny.
Who we work with
Built for organizations that operate at scale on Canton.
Validator operators
You earn rewards, pay domain fees, and manage delegations — every month. OS Ledger gives your finance team a structured close workflow, a defensible audit trail, and QuickBooks-compatible exports. No more spreadsheets.
Enterprise participants
Canton is designed for institutions. Your operational tooling should match that standard. Outer Sunset builds the software that sits between Canton's protocol layer and your finance, compliance, and audit teams.
Systems integrators
Building a Canton deployment for a client? Outer Sunset products slot into the operational stack without requiring custom accounting infrastructure. Talk to us about integration and white-label options.
