What you get
Many projects fail after deployment because the operational layer is missing. We design for the bigger picture: backend services, indexing, and monitoring so the system can run in production.
We ship contracts that are maintainable, testable, and safe to operate over time.
Contract architecture & design
+Define modules, permissions, upgrade strategy, and failure handling. Output: spec + architecture mapping from business rules to contract components.
Implementation (Solidity)
+Clean, reviewable code with clear interfaces and documentation. Output: contracts ready for integration and staged rollout.
Testing strategy
+Unit tests, integration tests, and invariant/property-based testing where it matters. Output: test suite designed to catch regressions and edge cases.
Upgradeability & migrations
+Upgrade paths that don’t break integrations or operational workflows. Output: upgrade/migration plan + scripts + runbooks.
Deployment pipelines
+Repeatable deployments, configuration management, and release discipline. Output: deployment scripts, environments, and checklists.
Integration support
+Contract interfaces designed to fit backend services, indexers, and reporting outputs. Output: integration guidance + event design that supports downstream systems.
Common use cases
Scenarios where robust engineering matters more than just "making it work".
Token contracts and lifecycle logic
+Issuance, transfers, restrictions, redemption-oriented flows, and role-based permissions.
Stablecoin payment primitives
+Escrow, routing, fee logic, settlement helpers, and programmable controls.
DeFi modules
+Lending/borrowing logic, interest accrual, collateral rules, liquidations, and fee models.
Protocol upgrades & refactors
+Upgrading legacy contracts safely, with staged rollouts and integration stability.

Smart Contract Engineering - Frequently Asked Questions
- What makes a Solidity smart contract "production-grade"?
- Production-grade means the contract is maintainable (clean, reviewable code with clear interfaces), testable (unit, integration, and invariant tests that catch regressions), upgradeable without breaking integrations (proxy patterns or migration scripts with documented runbooks), and observable (events designed to support indexing and downstream reporting). Contracts that meet only functional requirements but not operational ones typically require expensive rewrites within 12–18 months.
- What testing approach do you use for smart contracts?
- We write unit tests for individual functions and access control, integration tests for cross-contract interactions, and property-based or invariant tests for protocol-level constraints (e.g., total supply invariants, liquidation solvency conditions). We also include edge case tests derived from threat modeling. Test coverage is a starting point - we prioritize testing the scenarios most likely to cause real failures.
- How do you handle smart contract upgradeability?
- We evaluate whether upgradeability is actually required before adding proxy complexity. When it is needed, we implement transparent or UUPS proxy patterns with clear upgrade authorization and time-lock controls. Every upgrade includes a migration runbook, rollback procedure, and pre/post-upgrade verification tests. We don't add upgrade mechanisms as a default - they increase attack surface.
- Do you work with existing codebases or only greenfield projects?
- Both. For existing codebases we start with a code review to understand the architecture, identify risks, and define what safe changes look like. Refactors and upgrades are delivered incrementally with clear rollback points. We have migrated legacy contracts on Ethereum (Alior Bank) and built greenfield protocols from scratch (Soil.co).
