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 (North America overlap).

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 (Canada)

For Canadian teams, we focus on practical privacy and security: least-privilege access, clear boundaries, and reviewable operational controls.

We can align implementation with SOC 2 / ISO-friendly practices (without claiming certification) and support documented data flows.

  • SOC 2 / ISO-friendly patterns (no certification claims)
  • Least-privilege access and secure session handling
  • Retention/deletion and export flows where required
  • PII-safe logging + access boundary documentation
  • NDA and vendor onboarding docs on request

Timezone & Collaboration (North America)

We work with Canadian teams with North America overlap and meeting windows that fit your schedule.

Delivery stays predictable via weekly milestones, async updates, and clearly documented decisions.

  • North America overlap and responsive communication
  • Async-first updates with written scope decisions
  • Weekly milestone demos and progress checkpoints
  • Clear escalation path for blockers
  • Tight change control with clear sign-offs

Engagement & Procurement (Canada)

We support procurement-friendly delivery: clear scope, change control, and billing cadence aligned to milestones when appropriate.

We can invoice in CAD for CAD-based engagements where required.

  • CAD-based engagements and invoicing options
  • Milestone-based billing and scope sign-offs
  • Time-and-materials for evolving requirements
  • Vendor onboarding pack on request
  • Optional paid discovery to de-risk delivery

Security & Quality (North America)

We keep quality visible: clean PRs, reviewable changes, and test coverage that matches the risk of each feature.

Performance budgets and release discipline help maintain stability as the product scales.

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