Wallet-connected frontend
Wallet connection, account and network selection, signed actions, transaction status and recovery from rejected or failed transactions.
Blockchain application development
DApp development, from product scope to working application.
Build a blockchain product with the contracts, wallet experience, frontend, APIs and operator tools it needs. Start with one user journey and target network; agree delivery evidence before expanding the scope.
01
What a DApp development engagement can include
Select the modules your product needs. The statement of work lists deliverables, exclusions and the owner of each integration.
Smart contracts and programs
Data and asset models, role permissions, business rules, upgrade or migration decisions, tests and deployment scripts for the agreed chain.
APIs, indexing and admin tools
Event indexing, off-chain business data, role-based administration and operator workflows, with retry and reconciliation rules where required.
Testing and deployment handoff
A documented code version, test results, environment setup, contract addresses where deployed, release steps and an operating handoff.
02
Choose a chain around the product
A chain name alone does not define the scope. Confirm wallet coverage, transaction costs, finality, data access and the team's operating responsibilities.
Ethereum, Base, BNB Chain and EVM networks
Review Solidity contract requirements, wallet libraries, RPC capacity, indexer coverage and deployment targets. Adding another EVM network still requires network-specific testing.
Programs and account-based workflows
Scope program logic, account permissions, wallet transaction flows and event or account indexing separately from an EVM build.
Sui and Aptos
Evaluate the asset and object model, Move modules, wallet support and indexer path before confirming delivery. Chain-specific work is estimated after technical review.
03
What determines DApp cost and timeline?
A frontend prototype, a contract module and a complete production application are different purchases. A scoped estimate separates discovery, build, testing, deployment and ongoing support.
Scope and technical dependencies
The main variables are user journeys, networks, contract complexity, existing code quality, integrations, security review and operational requirements. RPC, hosting, gas and independent audit charges are identified separately.
Milestones with entry and exit criteria
Discovery confirms the architecture and acceptance plan. Implementation covers the agreed modules; testing covers normal and failure paths. Production rollout depends on environment access, review findings and customer release approval.
The starter is a scoping engagement
The pricing page lists a US$2,500 DApp Development Starter for architecture review, wallet-flow scope and delivery planning. It is not the price of a complete DApp. Confirm the written scope and invoice before payment.
04
How the application is accepted and handed over
Agree measurable checks before coding. A successful deployment is one item in the acceptance record, alongside product behavior and operating readiness.
Verify the complete user journey
Test wallet connection, wrong-network handling, rejected signatures, transaction confirmation and the resulting business state. Record expected outcomes and unresolved limits.
Test permissions and failure paths
Check role boundaries, duplicate events, delayed indexing and recovery after service interruption where relevant. Record the release commit, test environment and retest results.
Make the handoff reproducible
Deliver the agreed source, build instructions, dependency and environment notes, deployment records and monitoring guidance. Confirm repository access, software licenses and source ownership in the contract.
Agree support separately
Document defect handling, support hours, response expectations and the change-request process. Independent audit, mainnet launch and ongoing operations are included only when specified in scope.
Plan the development engagement
Prepare the questions for scope, handoff and partner collaboration. These guides are in simplified Chinese.
DApp cost and timeline
Scope, cost drivers and milestone estimates.
Source and deployment handoff
Review acceptance evidence and operating handoff.
Working with an engineering partner
Agree responsibilities, code access and support.
Common project questions
Understand the engagement before requesting a quote.
Can DAPPWEB deliver both smart contracts and the application?
Yes. An engagement can include contracts or programs, wallet integration, frontend, APIs, indexers, admin tools and deployment handoff. The proposal identifies which modules are included and which depend on an existing provider.
Can another development agency use DAPPWEB as an engineering partner?
Yes. We can scope a module, implementation milestone or technical handoff with product studios and integration teams. Agree customer communication, repository permissions, source ownership, confidentiality and acceptance responsibilities before work starts.
What should I provide to request a DApp quote?
Share the user journey, target network, must-have features, current repository or wireframes, integrations, budget range and launch target. Do not include private keys, seed phrases or API secrets.
Is payment integration part of DApp development?
It can be included when the product needs it. Order state, provider callbacks, reconciliation and recovery are scoped as a separate integration workstream. See the payment integration service for those deliverables.
