Complete Hiring Guide
Everything You Need to Know
Solidity is the language for Ethereum smart contracts. The question is not just 'can this person write Solidity' — it is 'can this person write Solidity that doesn't get exploited.'
The Solidity Skills That Separate Junior from Senior
Junior Solidity developer:
Can implement a contract to a provided specification. Knows the ERC-20 standard. Has used OpenZeppelin. Can write unit tests for happy paths. Does not have independent security intuition.
Senior Solidity developer:
Designs the contract architecture from business requirements (no specification required). Identifies attack vectors during design — not just in code review. Has encountered and fixed reentrancy, oracle manipulation, and access control vulnerabilities in production code. Can manage an external audit engagement and respond to findings technically.
What We Deliver
Our Solidity development engagements include: formal specification authored by a senior Solidity architect, development by experienced engineers against that specification, internal security review (Slither, Mythril, manual review by a senior engineer who did not write the code), and independent external audit management. We do not place solo contractors. We deliver complete systems with production-ready security posture.
