dApp Development Company

dApp development pricing depends on protocol complexity, audit scope, and chain targets. A functional MVP — single smart contract system, basic frontend, internal testing — typically runs $40,000–$80,000. A full-scale DeFi protocol or RWA tokenization platform with multi-chain deployment, third-party audit, and compliance modules ranges from $150,000 to $400,000+. Annual maintenance averages 15–20% of initial development cost. We provide fixed-scope estimates after an initial architecture session.

We deploy primarily on EVM-compatible networks: Ethereum mainnet, Arbitrum, Optimism, Linea, Polygon zkEVM, and BNB Chain. For Solana-native projects, we use Rust with the Anchor framework. Chain selection is driven by your TPS requirements, gas cost tolerance, and the liquidity or user base already present on a given network — not by our internal preferences.

For any dApp handling real user funds, an external audit is non-negotiable. Smart contract exploits cost the industry over $3.1 billion in 2025 alone. Audit duration depends on contract line count and complexity: a single ERC-20 token contract takes 1–2 weeks; a multi-contract DeFi protocol takes 4–6 weeks. We prepare contracts for audit with documented invariants, Natspec comments, and Slither pre-screening to minimize auditor turnaround time and remediation rounds.

We implement Account Abstraction using the ERC-4337 standard. Users interact through smart contract accounts rather than EOAs. This enables login via Apple ID, Google OAuth, or biometrics; gasless transactions funded through Paymaster contracts; and social recovery mechanisms that restore account access without a seed phrase. The result is a Web2-equivalent UX layer over a fully non-custodial architecture — what the market calls a "Web2.5" experience.

Yes. For EU-market dApps, we design around Crypto Asset Service Provider (CASP) requirements from day one: on-chain client asset segregation, transparent transaction reporting, and AML monitoring integration. For stablecoin issuers, we address e-money token (EMT) requirements including reserve attestation logic. Compliance architecture is documented as part of the technical specification deliverable — not retrofitted post-launch.

Ethereum mainnet (L1) provides the highest security guarantees but costs $5–$50+ per transaction during congestion and has limited throughput (~15–30 TPS). Layer 2 networks like Arbitrum or Linea settle to Ethereum for security but execute transactions off-chain, achieving 100,000+ TPS at sub-$0.01 per transaction. For most dApps in 2026 — DeFi, NFT marketplaces, gaming, DAO tooling — an EVM-compatible L2 is the correct default. We help you quantify the tradeoffs based on your specific transaction volume projections.

Reentrancy protection is implemented structurally — using checks-effects-interactions pattern, ReentrancyGuard from OpenZeppelin, and pull-payment patterns where appropriate. Beyond reentrancy, we audit for integer overflow/underflow (mitigated via Solidity 0.8+ built-ins), flash loan attack vectors, oracle manipulation risks, and access control gaps. Fuzz testing with Echidna generates thousands of randomized inputs against defined invariants, catching edge cases that manual review misses.

Full IP transfer is standard in our contracts. Upon completion and final payment, you receive: all smart contract source code with verified deployment history, front-end repositories, infrastructure access credentials, and all signing keys. We do not retain license rights or back-door access to deployed contracts. Ownership is unambiguous and documented in the development agreement.

A well-scoped dApp project runs 10–14 weeks from kickoff to mainnet deployment. The breakdown: 1–2 weeks for protocol design and architecture review; 4–6 weeks for smart contract development and internal testing; 3–4 weeks for third-party audit and remediation; 1 week for frontend integration and mainnet deployment. Timelines extend for projects requiring multi-chain deployment, complex governance systems, or regulatory compliance modules requiring legal review.

Yes. AI integration in Web3 takes two forms: (1) AI-assisted development — using LLM-based tooling for code pre-audit, gas optimization, and NatSpec generation during our build process; and (2) AI agents as on-chain actors — architecting dApps that accept autonomous agent transactions via ERC-4337 smart accounts, enabling micropayments and data exchange without human approval at each step. We assess the trust model for any AI-controlled account and implement appropriate rate limits and multi-sig override mechanisms.

Yes — decentralized exchange development is one of our core verticals. We build AMMs, order-book DEXs, and hybrid liquidity protocols on EVM-compatible L2 networks, with MEV protection, on-chain governance, and gas-optimized Solidity contracts audited before mainnet launch. You can explore architecture patterns and product configurations on our DEX solutions page. A typical DEX MVP — core swap logic, liquidity pool contracts, and frontend integration — ships in 10–14 weeks with a third-party audit included in the scope.
