# Custom Blockchain & Web3 Development Services Services for Growing Businesses

Build secure, scalable smart contracts, DeFi protocols, and Web3 solutions on Ethereum and EVM-compatible networks. Our blockchain development services include Solidity smart contracts, gas optimization, and full-stack dApp development.

## Best for

Startups launching utility tokens, NFT collections, web3 authentication integrations, and connecting legacy web platforms to decentralized protocols.

## What the service includes

- Solidity Smart Contracts
- Hardhat & Foundry Testing
- Web3.js / Ethers.js Wallet Connections
- DeFi & NFT Protocol Integration

## Technology stack

The listed stack covers Solidity contracts, EVM-compatible chains, contract tooling, and frontend wallet connections.

Solidity, EVM Chains, Hardhat & Foundry, Ethers.js / Wagmi, Next.js Smart Frontends

## Business model

### Technical discovery and scope

Review the contract behavior, chain requirements, and integrations, then quote the work based on the technical scope.

### Contract and dApp implementation

Build the agreed smart contract and application integration, with contract testing included in the implementation scope.

### Phased delivery

Agree milestones for development, testing, integration, and release after scoping the required functionality.

## Frequently asked questions

### What blockchain development work do you offer?

The listed work includes Solidity smart contracts, DeFi and NFT integrations, wallet connections, and dApp frontends on Ethereum and EVM-compatible chains.

### Which tools are used for smart contract development?

The published stack includes Solidity, EVM chains, Hardhat, Foundry, Ethers.js, and Wagmi. Tool choices depend on the chain and product requirements.

### Are smart contracts tested?

The service scope lists Hardhat and Foundry testing. Testing requirements are agreed alongside the contract behavior and integrations during technical discovery.

### How are blockchain projects estimated?

Projects are quoted after a technical review of the contracts and integrations required. The timeline is agreed after scoping development, testing, and release requirements.

### Which networks can you build for?

The published service focuses on Ethereum and EVM-compatible networks. The target chain is selected after reviewing deployment, wallet, and integration requirements.

### Does smart contract testing include an independent security audit?

The service includes contract testing with Hardhat or Foundry. An independent security audit is a separate specialist engagement and should be arranged before production use when required.

### Can you connect a dApp to existing contracts or wallets?

Yes. Wallet connections and EVM integrations are listed capabilities. Existing contract interfaces, target networks, and wallet requirements are reviewed before estimating the integration.
