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. dApps with wallet flows, chain UX, and safe transaction handling (EU overlap (CET/CEST-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)

DAO & Governance Apps
Proposal creation, voting flows, and treasury visibility with safe permissions and clear signing/transaction UX.
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 (EU)
For Germany/EU delivery, we keep GDPR-first patterns: data minimisation, purpose-limited storage, and explicit access boundaries.
We can work under a DPA (template available on request) and implement pragmatic retention/deletion flows when needed.
- GDPR-first architecture patterns (generic, no legal claims)
- DPA template available on request
- Retention/deletion and export flows where required
- Least-privilege access and safe logging defaults
- Documented data flows and access boundaries
Timezone & Collaboration (EU)
We align to EU working hours with CET-friendly collaboration windows and async progress updates.
We keep delivery predictable: weekly milestones, documented decisions, and clear scope control.
- EU overlap with CET-friendly windows
- Async-first delivery with written decisions
- Weekly milestone demos and progress checkpoints
- Clear change control to avoid surprises
- Escalation path for blockers and risks
Engagement & Procurement (EU)
We support procurement-friendly engagements with clear scopes, milestone plans, and documentation that stakeholders can review.
For EU teams, we can structure invoices and milestones for EUR-based engagements where appropriate.
- EUR-based engagements and invoicing options
- Discovery-first option to reduce delivery risk
- Milestone-based billing and scope sign-offs
- Vendor onboarding documentation on request
- Transparent change control and approvals
Security & Quality (EU)
We prioritise reliability: reviewable PRs, predictable releases, and tests that protect critical paths.
Performance budgets and clear release discipline keep the product stable as it grows.
- CI-friendly testing: unit + integration + smoke tests
- Performance budgets + bundle checks
- Release checklist + rollback-safe deployments
- Security checklist for auth and sensitive data flows
- Observability hooks (logs + error tracking) ready for production
