- Reconciliation dashboard and documentation
Best fit for
- SaaS and digital products
- Web3 merchants
- Client-owned checkout systems
Direct settlement to the client
The integration can generate payment references or client-controlled receiving addresses, monitor chain confirmations and reconcile payments with internal orders. TierZero does not receive, pool, exchange or forward customer funds.
The client is responsible for supported jurisdictions, sanctions controls, taxes, refunds and any licensing analysis applicable to its business model.
Delivery and operational boundaries
TierZero provides software engineering, testing, documentation and deployment support. The client controls its infrastructure, accounts, credentials, wallets and product decisions. We do not custody client or end-user assets, transmit funds on a client's behalf, operate customer trading accounts, recommend specific investments or guarantee financial results. Production use remains subject to the client's legal, compliance and risk review.
Technical scope
What we design and verify
A production on-chain payment integration is more than a working demo. Each major component below is scoped around the target network or platform, expected load, failure conditions and the way your team will operate it after handover.
Payment request and invoice flow
This part of On-Chain Payment Integration is specified as a separate, testable component with acceptance criteria, logging and documented configuration rather than hidden hard-coded behavior.
Chain confirmation monitoring
Operational visibility is part of the delivered system: health, important actions, failures and relevant business metrics are exposed without placing private keys in the interface.
Webhook and order-state integration
Submission and execution logic includes simulation, configurable limits, explicit failure states and structured logs. Production credentials and signing authority remain separated from application logic.
Underpayment and duplicate-payment handling
This part of On-Chain Payment Integration is specified as a separate, testable component with acceptance criteria, logging and documented configuration rather than hidden hard-coded behavior.
Reconciliation dashboard and documentation
Operational visibility is part of the delivered system: health, important actions, failures and relevant business metrics are exposed without placing private keys in the interface.
Definition of done
Before delivery, we validate the agreed happy path, expected failures and operational controls. You receive the applicable source code, configuration reference, deployment instructions and a walkthrough of the system. Any third-party fees, infrastructure subscriptions or external dependencies are identified during scoping.
Delivery
How the engagement works
Technical discovery
We confirm the objective, constraints, integrations and acceptance criteria.
Architecture & scope
You receive milestones, responsibilities, timeline and the final quote.
Build & verification
Implementation is tested against the agreed scenarios with visible progress.
Handover & support
We deploy or hand over the code, documentation and operating instructions.
Built for production
Scope, security and ownership
Delivery model
Application, data and infrastructure components are scoped as independently testable services with clear interfaces.
Security baseline
Secrets, authentication, observability, backups and deployment access are handled with least-privilege defaults.
What we need from you
User flows, integrations, traffic expectations, hosting constraints and existing code or infrastructure.
Questions before you start
What is included in the On-Chain Payment Integration starting price?+
The $1,500 figure is a starting point. We confirm the exact scope, integrations, acceptance criteria and fixed quote before work begins. The listed deliverables are included unless the agreed proposal says otherwise.
How long does delivery take?+
Timing depends on integrations, testing depth and whether existing code is involved. After a short technical discovery, we provide milestones and a delivery estimate before payment.
Who controls the source code, infrastructure and keys?+
The agreed source code and deployment are handed over to the client. Production wallets, seed phrases and private keys remain client-controlled; we design integrations around scoped credentials and least-privilege access.
How do we verify the result?+
We agree measurable acceptance criteria before implementation, then provide testing evidence, documentation and a handover walkthrough for the delivered scope.
Can you work with our existing code or infrastructure?+
Yes. We can begin with a focused review, identify reusable components and propose the smallest safe implementation path instead of forcing a full rebuild.
