Technical scope
What we design and verify
A production dapp development 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.
Next.js dApp with wallet connect
Wallet and account workflows use scoped permissions, explicit transaction review points and client-controlled secrets. Seed phrases are never required for ordinary development access.
Contract integration (wagmi/viem, web3.js)
The component is verified against agreed scenarios and edge cases. Assumptions, privileged operations and known limitations are documented for the client team.
Live on-chain data & tx flows
This part of dApp Development is specified as a separate, testable component with acceptance criteria, logging and documented configuration rather than hidden hard-coded behavior.
Deploy, hosting & handover
Delivery includes repeatable setup instructions and a handover path for client-owned infrastructure, so operation does not depend on permanent access by TierZero.
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 dApp Development starting price?+
The $3,000 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.
