Web3 Development

dApp & DeFi Development

We build production-grade dApps: clean wallet flows, reliable contract interactions, and fast data layers. From DeFi dashboards to DAO tooling, we ship experiences that stay stable under real users and real network conditions. Web3 frontends built for reliability: signing, confirmations, and user safety (UK/EU overlap (GMT/BST-friendly)).

Benefits

What you get

Wallet UX Done Right

Clear connect/sign flows, transaction states (pending/success/fail), and guardrails for both new users and crypto natives.

Fast Data Layer

Indexing + caching for balances, positions, and activity feeds—so your UI stays responsive without overloading RPCs.

Multi-Chain (EVM) Support

Ethereum, Polygon, Arbitrum, Optimism, BSC and more—with safe chain switching, RPC strategy, and environment-based config.

Security-Aware Frontend

Read-only mode, permission boundaries, signature safety, and defensive UI against common Web3 edge cases and scams.

Features

What we deliver

Next.js/React dApp frontends with wallet-first UX

Wallet integration (MetaMask, WalletConnect, Coinbase Wallet)

Contract reads/writes using wagmi + viem (or ethers.js when needed)

Transaction flows: simulation, gas estimation, nonce handling, retries

Multi-chain configuration + chain switching with safe fallbacks

Real-time updates via event listeners + indexed activity feeds

DeFi integrations: staking, swaps, lending dashboards (protocol-dependent)

DAO tooling: proposals, voting UI, treasury views (safe read/write flows)

FAQ

Frequently asked questions

For modern React/Next.js apps we usually use wagmi + viem (great TypeScript support and clean hooks). We use ethers.js when we need lower-level flexibility or to match an existing codebase.

We design around real states: disconnected, wrong network, pending transaction, revert errors, and RPC timeouts. We also add read-only mode so users can explore first and only connect a wallet when they’re ready.

We combine contract event listeners with a cached/indexed data layer for feeds and dashboards. This keeps the UI responsive without excessive RPC calls.

We add simulation and clear gas estimates where possible, show total cost transparently, and handle common failure reasons (slippage, insufficient funds, allowance, network issues) with helpful UI messages.

Yes. We build responsive UIs that work well on mobile browsers and wallet apps (WalletConnect deep links). If you need native, we can also build a React Native wrapper with wallet support.

Delivery considerations for your region

Compliance & Data (UK/EU)

For UK teams, we default to GDPR-first thinking: data minimisation, purpose-limited storage, and clear access boundaries.

We can work under a DPA (template available on request) and implement practical retention/deletion flows when needed.

  • GDPR-first patterns (minimise, restrict, document)
  • DPA template available on request
  • Retention/deletion and export flows where required
  • Least-privilege access and secure session handling
  • PII-safe logging + secure-by-default configuration
  • NDA available for early-stage discussions

Timezone & Collaboration (UK/EU)

We align to UK time and EU overlap (GMT/BST with CET-friendly windows) for fast feedback cycles.

We keep the process lightweight: async updates, clear priorities, and written decisions to avoid ambiguity.

  • UK/EU overlap with GMT/BST windows
  • Async-first delivery with documented scope
  • Weekly milestones and structured demos
  • Clear escalation path for blockers
  • Tight change control with clear sign-offs

Engagement & Procurement (UK)

We support typical UK procurement flows with clear scopes, change control, and invoice cadence.

If you prefer a discovery-first engagement, we can run a short paid discovery to lock requirements before build.

  • GBP-based engagements and invoicing options
  • Discovery-first option to reduce delivery risk
  • Milestone-based billing when appropriate
  • Transparent change control and sign-offs
  • Vendor onboarding pack on request

Security & Quality (UK/EU)

We build for reliability and maintainability: clean PRs, tight review loops, and test coverage that matches risk.

Performance budgets and release checklists keep launches predictable—especially when multiple stakeholders review changes.

  • CI-friendly testing: unit + integration + smoke tests
  • Performance budgets + bundle checks (Core Web Vitals-minded)
  • Structured release notes and rollback-safe deployments
  • Security checklist for auth, roles, and data flows
  • Observability hooks (logs + error tracking) ready for production
