// Build

Web3 development built on security and trust

dApps, DeFi interfaces, smart contract integration, wallet connectivity, and on-chain data indexing. We build decentralised applications that users trust with their assets — because we treat security as a first-class engineering requirement.

// Standards

Web3 engineering standards

Security by design

Transaction simulation before signing, explicit approval display, signature verification, and no private key exposure anywhere in the stack.

Wallet-agnostic

WalletConnect v2 + RainbowKit support for 300+ wallets. No MetaMask dependency that excludes mobile users.

Gas-efficient UX

Gas estimation with buffers, batch transaction design, and clear gas cost display before every user action.

Multi-chain ready

Chain-agnostic abstractions that support Ethereum, Polygon, Base, Arbitrum, and other EVM chains without architecture rewrites.

Type-safe contracts

Typed contract interactions with viem + generated ABIs — eliminating a class of runtime errors from contract integration code.

On-chain monitoring

Event monitoring, transaction success tracking, and anomaly detection for production dApps handling user funds.

Common questions about Web3 development

Which blockchain networks do you build for?+

EVM-compatible chains (Ethereum, Polygon, Base, Arbitrum, Optimism, BNB Chain) and Solana. Multi-chain within a single dApp is supported through chain-agnostic abstractions.

Do you audit the smart contracts you integrate with?+

We conduct internal security reviews on all contracts we integrate with. For contracts we write, we recommend third-party audits for any contract handling significant value before mainnet deployment.

Do users need MetaMask to use our dApp?+

No — we implement WalletConnect v2 which supports 300+ wallet apps. For mainstream audiences, we can implement embedded wallets (Privy, Dynamic) that use email/social login without requiring any wallet installation.

Can you build a DeFi interface for an existing protocol?+

Yes — we build protocol interfaces for existing deployed contracts. We need the contract ABIs, deployment addresses, and protocol documentation to scope the integration.

How do you handle real-time blockchain data in the UI?+

The Graph subgraphs for indexed historical data (fast, cost-free queries), Moralis Streams or WebSocket subscriptions for real-time events, and polling with SWR/React Query for current state that changes periodically.
