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. Security-first smart contracts with clear audit-readiness posture (EU overlap (CET/CEST-friendly)).
Benefits
What you get
Security-First
Threat modeling, internal reviews, and test coverage from day one. We follow proven patterns and avoid risky shortcuts.
Gas-Aware Design
Efficient storage, careful loops, and batch operations where they make sense—without sacrificing readability or safety.
Proven Standards
OpenZeppelin-based implementations for ERC20 / ERC721 / ERC1155 with safe extensions for your use case.
Mainnet-Ready Delivery
Local + CI tests, deployment scripts, verification, and runbooks for upgrades, roles, and emergency controls.

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 (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
