Client Reviews

\"

The developer from Nexcode was writing clean, production-ready code from their very first PR. No ramp-up overhead, no hand-holding - they added value immediately. Exactly what we needed and could not find locally at this quality level.

Verified Review

Do blockchain developers also build the frontend?

Yes - our blockchain developers work with wagmi + viem for the Web3 frontend integration layer, alongside React for the UI. They handle wallet connection, transaction signing, on-chain state reading, and event subscriptions.

Do you audit your own smart contracts?

We do internal review (Slither static analysis, full manual review, test coverage for known attack vectors). For contracts holding significant value, we recommend and coordinate third-party audits from Consensys Diligence, Trail of Bits, or OpenZeppelin.
