Hire Solidity developers
Contracts, marketplaces and the indexing layer around them — written by people who treat the on-chain surface as the irreversible part, because it is.
What hiring a Solidity engineer here gets you
The terms, before the pitch.
Senior and mid+ Solidity engineers, billed per engineer per month with a three-month minimum, embedded in your team. Evidenced by a shipped Polygon marketplace with gas-optimised contracts and real-time indexing that reached $2.4M in first-month trading volume, and by NEAR on our client list.
The discipline that matters in this role is restraint about scope. A duplication bug in ordinary software is a rollback; a duplication bug that minted assets is a permanent supply change and often a legal conversation. Keeping the on-chain surface deliberately small is the cheapest way to control both risk and cost.
What a Solidity engineer covers here
Six things this role owns, rather than a list of technologies.
Contract development
ERC-721, ERC-1155 and custom contracts, written against a threat model rather than a feature list — reentrancy, access control, integer overflow, oracle manipulation.
Upgradeability, decided up front
Transparent or UUPS proxy patterns, chosen at deployment because they cannot be added to a deployed contract retroactively. Getting this wrong is unrecoverable.
Gas optimisation
Storage layout, batching and calldata work. On a marketplace this is not a micro-optimisation — it is the difference between users transacting and users bouncing.
Indexing and read paths
Subgraphs and event indexers, so the interface reads state in milliseconds instead of querying a chain per render.
Internal security review
Standard on every engagement, covering the four classes above. Not a substitute for an external audit, and we say which one you need.
Wallet and dApp integration
The frontend side: connection flows, transaction states, and making a pending transaction legible rather than a spinner.

How the engagement works
Six steps from a role brief to an engineer on your board.
Define the role
The stack, the seniority, and what the first month has to produce. That last part is the one most role briefs leave out, and it is the one that makes a shortlist useful.
Meet the engineers
You interview, against your bar and your process. If we do not have the right person for the role we say so rather than putting forward the nearest one — a bad match costs you a quarter.
Contract and NDA
An NDA before any of your code or design material is shared. You hold 100% of the IP from day one. Work can start within 1–2 weeks of signing.
Onboard into your process
Your board, your repo, your standups, your review conventions. The target for week one is a small change landed in your pipeline, not an architecture proposal.
Run it monthly
Billed per engineer per month, $4,000–$7,000 by seniority and from $4,000. Three months minimum, then rolling — below three months onboarding eats most of the value and both sides know it.
Scale or stop
Add engineers as the work grows, or end it with notice. A team of two to eight plus a tech lead is the usual shape, with a QA engineer when the work needs one.
When this is the wrong choice
Outstaffing is the wrong shape for some of the work people bring to it, and finding that out in month two is expensive for everyone.
You need an audit, not an engineer
Internal review is standard and it is not an audit. For contracts holding meaningful value the answer is a specialist firm — Trail of Bits, OpenZeppelin, Certik — which we arrange and pass through at cost.
The gameplay is meant to run on-chain
Block times are seconds and gameplay is milliseconds. Ownership belongs on-chain, the game loop does not, and crossing that line is where most Web3 game projects lose a year.
Tokenomics is the open question
That is an economics problem before it is an engineering one. A Solidity engineer will implement whatever you specify, faithfully, including a design that does not work.
Common questions
The three that come up on nearly every first call about this role.
What this role has shipped
Two deliveries, and the first one you can install.
Metarun — the ownership layer
Hero and skin ownership, access-ticket and genesis mints, and the marketplace those assets change hands in, on BNB Chain — inside a game that is live on Google Play.
