EVM Smart Contract System for Automated Trading Operations
Designed and implemented a production-grade contract architecture to manage strategy execution, permissions, and safe asset handling for automated on-chain operations.

What improved
Lower operational risk via explicit invariants and controlled execution flows, plus clearer monitoring signals for day-to-day operations and incident response.
The problem we were solving
Automated on-chain operations are easy to start and painful to operate safely. The scope focused on creating explicit execution flows, tight permissioning, and reliable safety exits for assets and operators.
- Multiple strategy operators with different permission levels
- Safe withdrawals with explicit invariants
- Event instrumentation for monitoring and incident review
Design choices that reduce risk
The architecture emphasized separation of responsibilities and tight access control, with clear surfaces for execution, custody boundaries, and recovery paths.
- Role-based permissions and explicit operator management
- Guardrails on execution to prevent unintended calls
- State + events designed for operational observability
How it was shipped
Delivery included a tested Solidity codebase and practical deployment documentation to reduce the risk of misconfiguration and to support future upgrades.
- Unit + integration tests for critical flows
- Deployment and rollback checklist
- Migration plan for moving from prior contracts
What was handed over
- Solidity codebase + tests
- Deployment notes and rollback checklist
- Migration plan and upgrade guidance
- Instrumentation notes (events and monitoring hooks)
