# PopeyeX ## Centralized Cryptocurrency Exchange — Source Code for Sale *Summary for prospective buyers · September 2026 · Web version: * A working centralized cryptocurrency exchange — spot, USDT-margined perpetual futures, web, admin console and native mobile apps — with its full source code, for a one-time **$15,000 USDT**. > **$15,000 USDT** · one-time · non-exclusive source-code licence · no royalties > Comparable exchange source packages are offered at around $150,000. --- ## 1. What You Get PopeyeX is a centralized cryptocurrency exchange that ran in production in 2025 and has since been shelved. We are offering the platform itself: the complete source code, the build tooling, the database schema, and a single-node deployment that boots the whole exchange with one command. **You skip the expensive part.** We have already put a five-figure sum into getting PopeyeX running again — packaging it, fixing the security defects we found, building a one-command deployment and getting the end-to-end test to pass. Comparable exchange source packages are offered at around $150,000; PopeyeX costs a tenth of that. This is a **non-exclusive source-code licence** for a one-time fee. You get the complete source, run it on your own infrastructure and change it however you like — no royalties, no revenue share and no ongoing dependency on us. Hefes keeps ownership of the code and may license it to other buyers. ## 2. The Exchange - **Spot trading** on a built-in matching engine — limit and market orders, live order books, trade history and maker/taker fees. - **USDT-margined perpetual futures** — adjustable leverage, isolated and cross margin, mark pricing, funding, take-profit/stop-loss and liquidation, running on a dedicated engine per trading pair. - **Member accounts** — email registration, Google Authenticator two-factor, fund password, identity verification, deposits, withdrawals and internal transfers. - **Secondary products present in the code** — copy trading, P2P, simple earn, launchpad, token sets and coin conversion. These were not all exercised in the demonstration; the diligence pack states exactly which features were verified. ## 3. Operator & Compliance Console - Member management and identity-verification (KYC) review. - Withdrawal review and approval queue — customer withdrawals wait for an administrator. - Configuration of coins, spot trading pairs and perpetual contracts — leverage tiers, fees and margin requirements. - Risk, compliance and large-transaction monitoring. - Market-making robot and price-feed management. - Role-based administrator permissions and an audit log. ## 4. Platform & Clients - **Web exchange** — Next.js 15, with translation bundles for 17 languages. - **Admin console** — React and Ant Design. - **Native Android and iOS apps** — supplied as source. - **Backend** — 26 Java / Spring Cloud microservices on JDK 17, with MySQL 8, MongoDB, Redis, Kafka, RocketMQ and Nacos. - **Integration points** for custody, KYC providers, SMS and email, and Indian payment rails (UPI) — you connect them with your own provider accounts. ## 5. Ready for Diligence - ✅ **Boots on one machine** with Docker; every image is built from the supplied source. - ✅ **An end-to-end test passes 27 of 27 steps** on a fresh install — registration, identity approval, a matched and settled spot trade, a perpetual position opened and closed, and a withdrawal reaching the review queue. - ✅ **Security-reviewed during packaging.** The defects found were fixed, and each one is documented for the buyer. - ✅ **A full documentation set** — architecture, installation, operations runbook, admin manual, configuration reference, security hardening guide, upgrade roadmap and a written disclosure. ## 6. Barebone — What You Bring PopeyeX is deliberately barebone: the trading engines, operator console and apps are done, and the regulated layer is left for you to choose. Before going live you'll need: - **Custody** — a custody and wallet-infrastructure provider such as Fireblocks, connected through the custody integration point. - **KYC/AML** — your own identity-verification and AML screening provider, and your compliance programme. The console already has the KYC review and withdrawal-approval workflows. - **A licence** — the registration or licence to operate an exchange wherever you launch. No licence is included, and none can be transferred. ## 7. Sold As-Is — Please Read We would rather you hear this from us than find it in diligence: - **No licences, registrations or regulatory approvals transfer.** Operating an exchange is regulated in most jurisdictions, and that is the buyer's responsibility. - No users, balances, liquidity, trading history or production data are included. - No third-party credentials are included; each integration is configured with your own accounts. - The backend descends from an Apache-2.0 open-source project and has been substantially extended since; its lineage is documented in the diligence pack. - Parts of the application framework (Spring Boot 2.x) are past end-of-life. A costed upgrade roadmap is included. - The mobile apps are supplied as source and must be re-signed and rebuilt before release. - No warranty and no ongoing support are included; customisation and hands-on help are available as separate paid work. - The licence is non-exclusive: the same codebase may be licensed to other buyers. ## 8. Need It Customised? PopeyeX is sold as-is, but it doesn't have to stay that way. We can take on branding, custody and KYC/AML integration, new markets and trading pairs, the Spring Boot upgrade, or deployment on your infrastructure. Tell us what you need and we'll scope and quote it separately. ## 9. How a Purchase Works 1. **Enquire** — tell us who you are and what you intend to do with the platform. 2. **NDA** — we sign a mutual non-disclosure agreement. 3. **Demo & diligence** — a live walkthrough of the running demo, plus access to the documentation, the disclosure and the source code. 4. **Close** — licence agreement, a one-time payment of $15,000 in USDT, and delivery of the full source repository. --- ## Next Steps Email or message us to start a conversation — including if you need customisation.
