Common questions, straight answers.
The questions we hear most from founders, treasuries, and protocol teams considering an engagement.
What you actually want to know.
Not exhaustive — just the questions we get asked at least weekly. If yours isn’t here, write to us.
Engagement basics
How does scoping work?
After a scoping call we send a written proposal with deliverables, timeline, and named engineers. If the scope changes, we document the change explicitly, in writing, and only with your sign-off.
What's the smallest engagement you take?
We typically don't take work under two weeks of senior time — the overhead of scoping, kicking off, and signing reports doesn't make sense below that. If you have a tighter brief, write to us anyway; we'll point you somewhere good if it isn't a fit for us.
How fast will you reply to a brief?
A senior engineer reads every brief and replies within two business days with scope, timeline, and next steps — or with an honest "this isn't us, here's who you should talk to."
Working together
Where are you based?
Mozaca Labs is a globally distributed studio. We work asynchronously and use working hours overlap as the rule that decides who staffs which engagement.
Who actually does the work?
The engineer on your kickoff call is the engineer on your code. We don't do bait-and-switch staffing. Every engagement names its team in the proposal.
Do you sign NDAs?
Yes. Mutual NDA on request, before any technical detail is shared. For audit work we also publish a redacted summary only with explicit written approval from the client.
Scope of work
Do you take audit-only engagements?
Yes. Smart contract audit is one of our three core services. We deliver a signed report with reproducible findings, severity ratings, and remediation guidance — and we re-test after fixes.
Will you build on a chain we choose, even if it isn't your favourite?
Within reason. We've shipped on EVM, Solana, Cosmos, and Stellar. If you bring a brief on a chain we don't have working production experience with, we'll tell you up-front and either staff the right expertise or refer you out.
Do you offer ongoing retainers?
Yes — for clients we've already shipped with. Retainers are scoped monthly around a named workstream, and either party can end them with 30 days' notice.
Products vs. services
Can I license Zent, Hazina, or Fedha?
Yes — all three are ready to ship. Tell us your use case (consumer wallet, business treasury, institutional digital-asset desk) and we'll scope a deployment path: white-label, API integration, or co-branded launch.
Are your products regulated?
Where regulation applies, we operate or partner through licensed counterparties. Specifics are shared under NDA during scoping.
Write to us — even a one-line question. A senior engineer will answer.
