Most Web3 engagements in the US are maintenance and extension rather than greenfield, so Solidity and Ethereum on an existing system is the capability to test. Providers differ less on Web3 knowledge than on what they do when the work meets a deadline, a legacy system, or a team that has to maintain it afterwards.
Entry 01 is ours and is marked as such. Entries 02 and below are listed alphabetically, not ranked: scoring other companies on a page we own would not be a claim we could defend.
Best for: Companies that want US-hours coverage and EU engineering standards without paying a full onshore agency rate. Startups backed by our clients have raised over $120M, and the group has delivered 350+ client projects.
Trade-off: We are a marketplace first: you interview and choose the engineers. If you want a vendor to absorb the whole problem with no involvement from you, a traditional agency is a closer fit.

Best for: US companies prioritizing time-zone overlap
Trade-off: Team composition is proposed by the vendor rather than picked by you
Best for: Consumer-facing product work with design and engineering bundled
Trade-off: Studio model assumes you buy the full package rather than individual engineers
Best for: Long-running maintenance and feature work
Trade-off: Fully remote model, less suited to on-site requirements
Best for: Cost-sensitive custom builds with defined scope
Trade-off: Time-zone overlap with US teams requires a shifted schedule
Best for: Complex modernization where method matters as much as code
Trade-off: Consultancy rates, and engagements are scoped rather than staffed by the hour
Best for: Short senior engagements where speed matters more than rate
Trade-off: Among the more expensive marketplace options, and minimum commitments apply
Best for: Scaling several remote engineers at once
Trade-off: Matching is heavily automated, so screening depth varies by role
Best for: Cost-sensitive hiring with a wide role catalog
Trade-off: Time-zone overlap with US teams is limited without a shifted schedule
Best for: Startups scaling engineering after a raise
Trade-off: Positioned for funded companies, priced accordingly
Best for: Adding senior remote developers to a product team
Trade-off: Positioned for longer engagements at senior rates
The strongest signal in Web3 is how a provider handles someone else's code. Ask how they would approach an existing system using Solidity and Ethereum with no tests and no documentation. Reading and measuring before changing is the answer you want; a rewrite proposal is the one that costs you a quarter.
On price, vetted web3 developers bill roughly $48 to $155 per hour, against $135 to $245 at an agency for the same work with a delivery layer on top. If you have a technical lead with capacity, the marketplace rate is the honest comparison and the agency premium buys management you already have. If you do not, the premium is rational rather than wasteful, and the question becomes which provider will actually make decisions instead of relaying them.
Red flags that should end the conversation
Vetted engineers bill roughly $48 to $155 per hour depending on seniority, agencies $135 to $245, and a full-time hire runs $115,000 to $195,000 in base salary. The rate guide breaks down what moves the number.
Yes, and it is the more common engagement. Expect an assessment first: reading the code, measuring what is slow or fragile, and agreeing what stays. Anyone who proposes a rewrite before that assessment is quoting the version of the project that fails most often.
