Web3 Development
dApp & DeFi Development
Production-grade Web3 UIs: wallet connect/sign flows, transaction states, contract reads/writes, and a fast data layer for dashboards and activity feeds. If you need a DeFi dApp development services company for staking or liquidity views, we build safe experiences with clear edge-case handling.
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 development company UK delivery patterns: staking, swaps, lending dashboards (protocol-dependent)
DAO tooling: proposals, voting UI, treasury views (safe read/write flows)

Use Cases
Who this is for
DeFi Dashboards
Positions, rewards, staking, swaps, and portfolio views with accurate on-chain data and a UI that stays fast at scale.
Token & NFT Experiences
Minting, claiming, transfers, and gated access—paired with clean transaction states and reliable metadata display.
DAO & Governance Apps
Proposal creation, voting flows, and treasury visibility with safe permissions and clear signing/transaction UX.
AI Add-ons
AI add-ons we can integrate
AI can help Web3 products reduce support load and improve onboarding—without changing your on-chain trust assumptions. We integrate assistants, RAG knowledge bases, and ops automations as optional modules around the dApp experience.
We keep AI features modular with safe fallbacks so critical transaction flows remain deterministic and user-trustable.
Includes: safety controls + monitoring baseline + handoff notes.
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
Data and risk discovery (United Kingdom)
Privacy, security, residency, and regulatory requirements differ by workflow. We document the applicable data flows, roles, retention needs, and control owners before recommending an architecture.
The resulting proposal lists the controls and evidence that are actually in scope. It is not a generic compliance, certification, or legal-assurance promise.
- Map data sources, destinations, roles, and sensitive fields
- Record access, retention, logging, and deletion requirements
- Identify required security or procurement evidence before contracting
- Use an NDA or DPA only when the parties mutually execute it
Working model (United Kingdom)
Exact live-overlap hours, response expectations, meeting windows, and escalation contacts are confirmed in the proposal for each engagement.
Written decisions, scoped milestones, and asynchronous updates reduce unnecessary meetings without implying an unagreed service level.
- Proposal-specific overlap and meeting windows
- Named owners for decisions and blockers
- Written scope, assumptions, and change decisions
- Milestone cadence agreed before kickoff
Commercial setup (United Kingdom)
The contracting entity, proposal currency, invoicing cadence, payment terms, intellectual-property terms, and required vendor documents are agreed before work begins.
The Opportunity Sprint can establish the evidence needed to scope a production pilot; it does not pre-commit either party to a rollout.
- Contracting entity and currency confirmed in writing
- Milestones and acceptance criteria defined in the proposal
- Vendor-document requirements identified before signature
- Scope changes require an explicit written decision
Delivery controls (United Kingdom)
Testing, observability, release, security, and handover controls are selected for the actual system risk rather than promised as a generic bundle.
Acceptance measures and production responsibilities are recorded before implementation so both teams know what evidence will support release.
- Risk-based testing and acceptance measures
- Release, rollback, and observability responsibilities
- Security controls tied to the agreed threat model
- Handover artifacts defined in the signed scope
