DappWeb builds EVM DApps, Solidity contracts, wallet frontends, admin dashboards, event indexers, and launch runbooks for Ethereum-compatible chains.

## What this service covers

DappWeb builds EVM DApps, Solidity contracts, wallet frontends, admin dashboards, event indexers, and launch runbooks for Ethereum-compatible chains. The scope can include product architecture, user journeys, contract or program integration, backend APIs, event indexing, admin dashboards, observability, deployment verification, and operating documentation.

**Disclosure:** This is service planning guidance, not evidence of a completed client deployment on every EVM network.

## Best-fit projects

Ethereum-compatible products that need contract logic, wallet UX, dashboards, analytics, and security review.

## Engineering decisions

- Choose the contract boundary first: Solidity contracts hold on-chain rules and state; APIs and indexers handle off-chain application needs.

- For an ERC-20 integration, define balances, allowances, approve/transfer flows, and how Transfer and Approval events update the interface.

- Record privileged roles, external calls, and upgrade decisions before connecting administrative actions to a wallet.

## Inputs required for scope

- Target chain and test environment, contract source or ABI, token addresses, wallet requirements, and the intended user journey.

- An explicit split between token operations, application data, and operator permissions, with expected failure behaviour.

## Acceptance evidence

- Requested acceptance: contract tests for permissions and business rules, plus wallet tests for rejected signatures, reverts, and insufficient allowance.

- For the agreed deployment: verified source, contract addresses, event-to-dashboard checks, and a named owner for privileged operations.

## Constraints and operating risks

An EVM-compatible chain still needs its own addresses, fees, wallet configuration, and release checks. A token contract alone does not provide the frontend, indexing, support tools, or business workflow.

## Security and compliance boundary

DappWeb provides technical services only: software development, smart contract review, analytics infrastructure, AI workflow implementation, and cloud operations. DappWeb does not manage client assets, provide investment advice, operate an exchange, or guarantee market outcomes.

## Buyer questions

### Is an ERC-20 contract a complete DApp?

No. ERC-20 specifies token functions and events. A usable product also needs wallet interactions, transaction feedback, application data, and the operator tools agreed in scope.

### What changes the development scope?

New contract rules, upgradeability, privileged actions, oracle dependencies, extra networks, and recovery requirements add distinct implementation and review work.
