dApp & smart contract FAQs.
Which chains do you work with?
We choose per use case after comparing chains, custody and infrastructure options. Our smart contract work has shipped across multiple chains.
How do you handle security?
Contracts go through a full audit before launch and every finding is worked through before deployment. Our most recent audit launched with zero critical findings.
Can you build the front end too?
Yes. We build the dApp interface and wallet connection alongside the contracts.
How long does a Web3 build take?
It depends on scope. For reference, we delivered a centralized exchange in 20 weeks and stablecoin payment rails in 5. We agree milestones up front.
