Hire Solidity developers

Honestly, for most Solidity briefs you should not. We did crypto work earlier — a consumer fintech app that was later acquired, a collectibles platform, a wallet, on-chain trading tooling — and the engineers who did it are still here, but it is not a practice we are currently growing and our records show three of them across two engagements. If contracts are the whole product, hire a firm that does only this. If contracts are one component of a product that also needs a backend, a web app and someone to keep it running, that is a conversation we can have.

Not quickly. There is no Solidity bench here to match you from, and we have opened one Solidity role in five years. Any engagement starts with whether the engineers who have done this work before are free, and if they are not, we will tell you rather than recruit into a practice we are not building.

Location matters less here than review discipline. Contract code is public, immutable once deployed and holds funds, so what protects you is a second engineer reading every line, a test suite that models adversarial behaviour, and an external audit before anything touches mainnet. Any vendor who will skip the audit to hit your date is telling you what they think of your users’ money.

Rarely just the contracts. A typical scope includes the on-chain logic, the tests around it, the deployment and upgrade path, and the backend that indexes chain events so your product can read state without hammering a node.

• Smart contract design, implementation, and test coverage.
• Deployment scripts and an upgrade strategy decided before launch.
• Event indexing and off-chain services that mirror on-chain state.
• Wallet integration and transaction handling in the client.

Adversarial tests alongside the happy path, covering reentrancy, access control, integer edges, and oracle assumptions. Internal review by a second engineer before anything leaves a testnet. A third-party audit for contracts that will hold meaningful value — we will tell you when we think you need one rather than leaving it as a line item you can quietly drop.

Yes. Most EVM-compatible chains reuse the same Solidity skills, so L2s and sidechains are usually a deployment and gas-model question rather than a rewrite. Non-EVM chains are a different language and a different talent pool, and we will say so upfront rather than stretching a Solidity team across a gap it cannot cover.
