SaaS Platform

Primary roadmap
Pending approval
proposed primary delivery

SaaS-first deployment where keys and signing remain under customer custody. First integration target: platform operations.

Direct sales contact is currently unavailable while commercial pricing, usage tiers, and licensing terms are pending owner approval.
Customer retains exclusive custody of signing keys, secrets, and funds
Hosted control plane for operator management, dashboards, and event delivery
Deposit detection, policy-bounded payouts, and transactional outbox webhooks
Multi-network derivation index separation without custodial commingling
Commercial subscription fees, billing provider, and usage quotas pending approval
Proposed primary delivery architecture. Service level agreements and response commitments are not yet approved.

Self-Hosted Stack

Pending approval
separately sold source stack

Full engine source code sold separately for operators requiring internal deployment, complete infrastructure autonomy, and local modification.

Sales inquiries are unavailable until licensing terms, commercial source rights, and distribution policies undergo legal and owner review.
Complete repository source stack across all bounded contexts and admin surfaces
Non-exclusive commercial license with source code access sold as a distinct offering
Runs on your infrastructure: your Postgres schemas, your servers, your networks
Independent key management and local signing without mandatory cloud dependencies
Offline policy, modification rights, and commercial license terms pending approval
Separately sold commercial edition. Perpetual guarantees, offline grace rules, and warranty terms are subject to owner decision and legal review.

Commercial and delivery questions

What commercial delivery models are planned?

The primary planned model is SaaS-first with customer key custody, where the client keeps signing keys and funds under their own control while using a hosted control plane. A full self-hosted deployment with source code is planned as a separately sold commercial edition for operators who run their own infrastructure.

What are the approved prices and licensing terms?

Prices, licensing terms, and billing models are currently under evaluation and have not yet been approved. Neither free perpetual usage nor specific fee schedules are authorized until owner decisions and legal reviews are finalized.

Are support SLAs or guaranteed response times available?

No guaranteed response times, emergency response SLAs, or dedicated engineer assignments are currently approved. Service level commitments will be published only after commercial terms and operational capacity are formalized.

Does the engine charge a percentage of custody or volume?

No volume-based fees or percentage-of-custody pricing are approved. The system architecture enforces customer key custody, meaning customer funds never pass through a vendor-held float.

How can developers evaluate the payments engine today?

Developers can review the bounded context architecture, examine the signing specifications in the documentation, and test workflows using the non-payable local simulation demo.
