Smart Contract Development

We design and build secure smart contracts for EVM chains like Ethereum and Polygon—tokens, NFTs, staking, governance, and DeFi primitives. Clean code, tested flows, and deployment support from testnet to mainnet. Smart contract delivery with test coverage, deployment checklists, and verification handoff (UK/EU overlap (GMT/BST-friendly)).

Use Cases

Who this is for

DeFi & Staking

Staking contracts, reward distribution, vesting, and simple DeFi building blocks with careful accounting and safety checks.

Tokens & NFTs

ERC20 launches, NFT drops, minting logic, allowlists, royalties, marketplaces hooks, and metadata strategies.

DAO & Governance

Voting systems, timelocks, treasury controls, multi-sig workflows, and governance modules that are easy to operate.

FAQ

Frequently asked questions

Ethereum is strongest for security and ecosystem. Polygon / Arbitrum are common for lower fees and faster UX. BSC is popular for low-cost transactions. We help you choose based on user needs, cost constraints, and integrations.

We do internal reviews and build contracts to be audit-friendly (tests, clear patterns, docs). For higher-stakes protocols, we recommend a third-party audit before mainnet launch and we support the full audit-fix cycle.

Yes, using upgradeable patterns like Proxy or UUPS. Upgradeability adds operational responsibility, so we only use it when it’s truly needed. Otherwise, we prefer immutable contracts with carefully designed parameters.

We optimize where it matters: storage layout, batching, minimizing writes, and avoiding expensive patterns. We balance cost with safety and maintainability—especially for contracts that will be audited.

A token or NFT contract can take ~2–4 weeks. Staking/vesting flows are often ~4–8 weeks. DeFi or governance systems vary widely and usually include an audit window. We’ll give a timeline after scope and risk review.

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
