Hire a Solidity developer, or hire someone to ship the whole thing?
A solo contractor at $80–150 an hour is the right answer if you have technical leadership. Most founders typing this query do not. The difference matters more than the rate.
Most founders searching this query land on Toptal, Arc, Upwork, Uplers, or web3.career. Each promises to match you with a vetted Solidity developer in 48–72 hours. The promise is real. The problem the founder usually has is not.
A Solidity contractor solves one specific problem: you need a senior engineer to write the smart contracts that your in-house team will integrate, audit, and deploy. If you have an in-house team that can do all of that, hiring a contractor is cheaper and faster than hiring an agency. If you do not, you are buying a kit car when you needed a working car.
When each one wins
Solo contractor
$80–150/hr
Right when you have a CTO, a frontend team, audit relationships, and a clear scope. The contractor writes contracts; you do everything else.
Agency MVP
€19–79k fixed
Right when you need contracts plus frontend plus integrations plus audit prep plus deploy plus a deadline. The whole product, not the part.
In-house hire
$200–250k/yr
Right after Series A when you have ongoing contract work for 12+ months. Wrong for a single MVP build.
The hidden cost of hiring just a contractor
A senior Solidity contractor on a marketplace bills $80–150/hr and delivers smart contract code. That is what they sell and what they are good at. Everything around the contracts is your job:
- Frontend development that integrates with the contracts
- Wallet integration, transaction state management, error handling
- Test environment, CI/CD, deploy scripts for testnet and mainnet
- Audit firm relationship, audit prep package, audit response
- Documentation, NatSpec, threat modeling for the auditor
- Project management, scope discipline, deadline enforcement on the contractor
If you have a technical co-founder who can do all of this, the contractor route is cheaper. Roughly $30–45k for the contract work at a senior rate, plus your co-founder's time on the rest. Total cash out of pocket is lower than an agency.
If you do not have that co-founder, you are about to spend your runway learning Solidity tooling instead of building distribution.
When the contractor route is right
Honest disclosure: agencies do not always win. The contractor route beats us when:
- You have a technical co-founder who can integrate, deploy, and manage the audit cycle.
- Your scope is contracts only — the frontend exists, the wallet integration exists, you need someone to write a specific module.
- You are augmenting an existing team rather than building from zero.
- Your timeline is not deadline-driven and you can absorb a rework cycle if the contractor underdelivers.
- You have done at least one prior web3 build and know what good looks like.
If two or more of these are true, hire a contractor. Skip the agency overhead.
When the agency route is right
You should be on the agency side of the line when:
- You are non-technical or technical-but-not-web3.
- You need contracts, frontend, wallet integration, and deploy in one engagement.
- You have a fundraise, launch, or grant deadline driving the schedule.
- You have never coordinated an audit and do not want to learn under pressure.
- You want one accountable party rather than three contractors and a Slack channel.
Hire a contractor if you have technical leadership. Hire us if you do not.
