Custom wallet, fintech and blockchain software, built by a team that runs it in production.
When an off-the-shelf module is not enough, we build what you need: a wallet app, a payment flow, an integration, a token, or a new product on top of your platform. The same engineers built and operate the exchange, wallet, custody and payment stack behind BitPolaris.

From one feature to a whole product.
Crypto wallets
Mobile (iOS and Android), desktop and web wallets: custody, recovery, multi-chain balances, notifications, and the store submission.
Payments and stablecoins
Checkout, invoicing, payouts, merchant panels and webhooks for USDT, USDC and other assets, with reconciliation built in.
Exchange features
Order types, market making, earn, launchpad, referral and reward programmes, and the admin tools your operations team needs.
Blockchain integrations
New chains and tokens, deposit scanning and sweeping, gas and TRON energy management, RPC failover and node operations.
Tokens and smart contracts
Token contracts from audited standard templates, vesting, multisig ownership, explorer verification and listing on your own exchange.
Fintech back office
KYC and KYB provider integrations, ledgers, reconciliation, reporting, Proof of Reserves and compliance exports.
We build what we already run.
Production experience
Our team runs a live exchange, wallet, custody and payment stack every day. We know which parts break at 3 a.m. and design for them from the start.
Money handled with care
Dry runs, two-person review and on-chain receipts for every treasury movement. The same habits go into the code we write for you.
Tested and documented
More than 1,000 automated tests behind our own stack, and written documentation with every delivery, so your team can run what we build.
Built for your markets
Interfaces and content in English, Turkish, Russian, Spanish, Arabic and Georgian, right-to-left layouts included.
Three ways to engage.
- Fixed-price project
- Scope, milestones and price agreed in a written proposal before work starts. Changes are quoted before they are built.
- Dedicated team
- Engineers working on your roadmap month by month, with a shared backlog and a demo at the end of every sprint.
- Extension of BitPolaris
- Custom modules built on top of a BitPolaris licence and carried forward with every update.
- Where it runs
- On your servers or hosted by us. You receive deployment scripts and documentation either way.
- Stack
- TypeScript, React, Next.js, React Native, Python, Ruby · PostgreSQL, MySQL, Redis, RabbitMQ · Docker · Bitcoin, EVM chains, TRON, Solana, XRP Ledger
In writing, from the first message.
- Step 1
Requirements
You describe what you need. We reply with written questions, not a sales call.
- Step 2
Proposal
Scope, milestones, timeline and a fixed price, within about a week.
- Step 3
Build
Milestone by milestone, each one demoed on a staging environment before it is signed off.
- Step 4
Launch and support
Deployment, handover documentation and an optional maintenance plan.
Questions
Do you work on systems you did not build?
Yes. We start by reading the code and documentation, then tell you in writing what we would change and what it costs.
How is the price set?
Per milestone, in the written proposal. Anything outside the agreed scope is quoted before it is built.
Do you sign an NDA?
Yes, before you share the details of your project.
Can you build on top of our BitPolaris licence?
Yes. Custom modules are built against the same codebase and carried forward when you update.
Have a project in mind?
Send a short description: what you want to build, for which users, and by when. We reply with written questions, then a proposal.
