On-Chain Payment Integration

Non-custodial payment software that lets a merchant receive supported on-chain payments directly into accounts it controls.

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.

01

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.

02

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.

03

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.

04

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.

05

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

01

Technical discovery

We confirm the objective, constraints, integrations and acceptance criteria.

02

Architecture & scope

You receive milestones, responsibilities, timeline and the final quote.

03

Build & verification

Implementation is tested against the agreed scenarios with visible progress.

04

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

How is On-Chain Payment Integration priced?+

We quote each project after discussing the required features, integrations and deployment. Send a short description; a finished specification is not required. We agree the scope, milestones and price before work begins.

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.

Discuss your project and get an estimate

A few sentences about your idea are enough. We'll clarify the requirements and prepare an individual proposal. No finished specification or payment is needed to enquire.
