FAQ
Frequently Asked Questions
Why are you 30% cheaper than market? Is quality compromised?
Two reasons: (1) fully remote — no office or sales-team overhead; (2) we maintain mature codebases for all 50 specialties, so we never charge you to reinvent wheels. Quality-wise, core members come from Coinbase, OpenAI, Google and peers; contract projects always include internal pre-audit plus an external audit firm report.
Is the quote final? Any mid-project price increases?
Before signing, we break requirements into a feature list written into the contract — a fixed all-in price. If you add new requirements mid-project, we quote them separately and only proceed with your approval.
Who owns the source code and IP?
You do, 100%. Delivery includes complete source code, deployment docs and technical docs, with the GitHub repo created under your own organization.
Not sure which option fits — can we talk first?
Yes, the first consultation is free. We'll recommend the most cost-effective path for your stage (fundraising / PMF validation / scaling) — and we'll openly talk you out of anything that isn't worth building.
Payment methods?
USD settlement or bank transfer. Standard schedule is 30-40-30: signing, mid-project demo, acceptance.
The team is pseudonymous — how do I verify capability?
Before signing we can arrange video due diligence (real faces), show sanitized case studies and deployed contract addresses; for contract work you may also appoint a third-party reviewer you trust.
How does 51kaifa.app relate to kaifaai.app?
Sister sites of the same team: 51kaifa.app covers full-stack Web3 development (chains, wallets, contracts, dApps, bridges); kaifaai.app focuses on AI-only products (agents, RAG, fine-tuning, digital humans). Both publish fixed prices and share one delivery standard.
How much for a Telegram mini app or bot?
TG mini apps are one of the 26 Web3 directions — see the full price table. Fixed price by feature list, written into the contract; no surprise add-ons.
How much and how fast for an MVP?
dApps/MVPs run $3,800–28,000; a validation demo ships in as fast as 12 hours, full MVPs in 4–8 weeks.
How much for an AI project?
All 18 AI directions are transparently priced from $3,800, ~30% below market. Per-direction pricing is on the price table.
How long does delivery take?
Websites 1–2 weeks, dApps/MVPs 4–8 weeks, L1/L2 chains 8–16 weeks. The schedule is written into the contract up front.
What if the project stops midway?
Milestone-based payments (30/40/30) with deliverables written into the contract. Stop anytime; source of delivered milestones is already yours.
Do you sign NDAs? Can I verify past work?
Yes. All 150 public cases are anonymized by type and region; client names, amounts and on-chain addresses stay under NDA.
How is smart-contract security handled?
Solidity and Rust, 95%+ test coverage, mandatory internal pre-audit; you can also appoint a third-party auditor of your choice.
What is included in delivery?
Full source code, deployment scripts and docs; the GitHub repo lives in your org. 60-day free warranty, long-term support optional.
What tech stack do you use?
Chosen per project: Next.js/TypeScript, Solidity/Rust, Cosmos SDK/Substrate, OP Stack, ClickHouse, etc. Trade-offs are explained in the proposal.
How is this different from Upwork/Fiverr?
A fixed team, milestone contracts, full source handover and a 60-day warranty — not solo gig work. See the side-by-side comparison.
Templates or built from scratch?
All 41 directions (23 Web3 + 18 AI) run on mature code libraries, customized to your needs — that's how pricing stays ~30% below market.
Can I start with just an idea?
Yes. The first scoping call is free (30 min); idea-only projects welcome — and we say no fast when a project doesn't fit.
Do you work in English?
Yes. Core members come from Coinbase, OpenAI, Google and other top teams; delivery is bilingual, with a full English site.
What do I do if my outsourced project stalls or gets abandoned?
Three steps to stop the bleeding. (1) Collect the deliverables you already paid for — source code, deployment scripts, technical docs. If the contract never listed deliverables, at minimum demand an export of the current repository snapshot. (2) Run a third-party code audit (1–2 weeks, from $3,800) to confirm the code is salvageable before putting more money into it. (3) Re-sign on milestone terms (30-40-30) and write every milestone deliverable into the contract. 51kaifa.app has taken over half-finished builds: assessment first, quote after, no charge if the assessment is not useful to you.
How much does it cost to build a blockchain, and how long does it take?
A custom L1 chain starts at $128,000 and takes 8–16 weeks; an L2 rollup starts at $68,000 and takes 6–12 weeks. Pricing covers the consensus layer, RPC nodes, a block explorer, SDKs and deployment scripts. If all you need is an application chain, building on OP Stack or the Cosmos SDK is materially cheaper and faster than writing your own consensus. Item-by-item prices are on the Pricing page.
