Custom Crypto & Web3
Development Services

Bespoke mobile apps, web platforms, Telegram bots, and AI chatbots — engineered by crypto-native developers for projects that have outgrown templates and freelancers.

Why Custom Engineering

Template solutions are fast to launch — and just as fast to break. We build systems that scale with your product, your users, and your long-term vision. Every project is tailored to your use case, not forced into a one-size-fits-all framework.

Crypto and Web3 specifically eat templated software for breakfast: wallet integrations break, RPC providers go down, contracts mutate mid-roadmap, and exchanges change their APIs every quarter. The projects that survive are the ones built on fundamentals that already understand those failure modes — and that is exactly what we engineer for.

How a BlockAI Engagement Runs

Every project follows the same disciplined process — discovery first, fixed scope second, weekly demos always. No surprises, no endless contracts.

  1. 01

    Discovery Sprint

    1–2 paid weeks where we map requirements, audit any existing code, design the architecture, and produce a fixed-scope quote you can take or leave.

  2. 02

    Design & Spec

    Wireframes, data models, contract interfaces, and a delivery plan with weekly milestones — signed off before a single production line of code is written.

  3. 03

    Build in Sprints

    Two-week sprints with a working build at the end of each. You get a staging environment, demo, and written progress note every Friday.

  4. 04

    Test, Audit, Harden

    Unit, integration, and end-to-end tests. Smart contracts go through internal review and an external audit when on-chain value is at stake.

  5. 05

    Launch & Maintain

    Production deployment, monitoring, and a defined warranty window. Most clients continue with us on a monthly maintenance retainer.

Engagement Models

Three ways to work with us, depending on whether you need a defined deliverable, ongoing velocity, or a permanent team extension.

Fixed-Scope Project

Defined deliverables, fixed milestone payments, and a clear definition of done. Best when requirements are well understood — MVPs, single-feature builds, contract suites.

Monthly Retainer

A standing engineering bench for ongoing work. Best when product velocity matters more than a frozen scope — feature backlogs, maintenance, optimisation.

Dedicated Team

Engineers embedded into your team and your tooling. Best when you need extra capacity that operates as part of your roadmap rather than as an outside vendor.

Industries We Build For

We are crypto-native, but our engineering team ships into the adjacent industries that crypto founders actually have to operate in.

Crypto & DeFi

Token dashboards, staking and vesting interfaces, on-chain governance, NFT mint flows, DEX integrations, and bridge UIs.

Fintech

Compliance-aware payment flows, KYC integrations, internal admin tooling, and analytics platforms for revenue and risk teams.

AI & Web3 Tooling

LLM-powered support bots, retrieval pipelines, agent workflows, and data-extraction platforms tailored to crypto-native use cases.

What's Always Included

Every BlockAI engagement, regardless of stack or scope, ships with the same baseline: clean code you can audit, environments you can deploy yourself, and operational visibility you do not have to ask for.

  • Production-quality TypeScript / typed code with linting and tests
  • CI/CD pipelines and reproducible deployments to staging + prod
  • Documentation: architecture diagram, runbooks, and a README that lets a new engineer ship in a week
  • Monitoring and alerting wired up before launch, not after the first incident
  • Source-code ownership transferred to your repos — no lock-in
  • Defined warranty window after launch with bug-fix-only support

Development FAQ

The questions founders ask us most often before kicking off a build with BlockAI.

What types of projects does BlockAI build?

We build custom mobile apps, web platforms, Telegram bots, and AI chatbots for crypto, fintech, and Web3 teams. Typical projects include trading dashboards, staking interfaces, token-gated communities, DeFi front-ends, AI customer-support bots, and admin tooling.

Which technology stacks do you work with?

Mobile: React Native, Expo, Swift, Kotlin. Web: Next.js, React, TypeScript, Tailwind. Backend: Node.js, Python, FastAPI, NestJS. Data: PostgreSQL, MongoDB, Redis. On-chain: Solidity, Anchor (Solana), Foundry, Hardhat. AI: OpenAI, Anthropic Claude, custom LLM pipelines.

Do you handle smart contract development?

Yes. We work with audited templates for ERC-20, ERC-721, ERC-1155, and SPL tokens, and we build custom contracts (staking, vesting, escrow, on-chain governance) on Ethereum, BNB Chain, Base, Arbitrum, Polygon, and Solana. All deployments are verified on the relevant block explorer.

How are projects scoped and priced?

Most engagements start with a paid 1–2 week discovery sprint where we map requirements, design the architecture, and produce a fixed-scope quote. From there, we run as fixed-scope milestone projects, monthly retainers, or dedicated team augmentation depending on what the project needs.

How long does a typical build take?

Discovery: 1–2 weeks. MVP web platform or mobile app: 6–12 weeks. Production-grade Telegram or AI bot: 3–8 weeks. Custom smart-contract suite: 4–10 weeks plus audit. We are explicit about timelines and update them weekly.

Do you provide post-launch maintenance and support?

Yes. Every build includes a defined warranty window, and most clients move into a monthly maintenance retainer that covers monitoring, patching, dependency upgrades, and incremental feature work. SLAs are tailored to whether the system is consumer-facing or internal.

Who actually does the work?

BlockAI's in-house engineering team — all crypto-native, all under direct project leadership. We do not white-label work to anonymous freelancer marketplaces. You can meet the engineers on your project before signing.
