Crypto Exchange Software
Digital Asset Exchange Infrastructure
Spot trading, wallets, ledger, fiat rails, AML/KYC, Travel Rule support, back office and production infrastructure — one modular platform, deployed around the customer's brand, jurisdiction and operating model and delivered as auditable operating infrastructure rather than a trading interface.
The Customer Problem
More Than a Trading Interface
Off-the-shelf scripts and unverified packages usually stop at the trading screen. In a regulated venue the real weight sits elsewhere: wallet security, financial records, AML/KYC workflows, permissions and the evidence an audit will request.
Projects built on incomplete foundations discover this close to launch: order and trade records fall short of audit expectations, wallet operations remain manual, and when vendor support ends the system cannot be extended.
Grumpio treats an exchange as an operating financial system: trading, wallets, ledger, AML/KYC, permissions, records, reporting and production infrastructure are designed as one platform. Deployment, customisation and regulatory-readiness work progress in parallel, and the system is documented for transfer to the customer's engineering team.
Module Scope
One Architecture. Every Exchange Module.
The modules below operate within one architecture; scope is configured per project around jurisdiction, authorisation and operating model. Spot trading is the default market, while margin, futures, perpetuals and OTC workflows remain optional modules that depend on jurisdiction-specific legal and authorisation assessment.
Spot trading and order management
Spot trading with market, limit and stop-limit order types, alongside an order book, trade history and real-time market data.
Wallet and custody
Hot, cold and multisignature wallet models with chain-specific deposit and withdrawal policies and pre-transaction risk checks. Third-party custodian integration is supported.
Ledger and financial records
Financial movements are maintained through double-entry and auditable transaction history rather than mutable balance fields; reconciliation data is produced by the system.
Fiat deposits and withdrawals
Bank transfer, vIBAN provider and multi-currency integrations with status management and limit controls; availability depends on the customer's authorisation and provider agreements.
AML, KYC and wallet risk
AML screening, KYC verification and blockchain wallet-risk checks are integrated into the onboarding flow through Legichain or the customer's selected providers.
Travel Rule support
Originator and beneficiary information, customer declarations and transfer-party identification with records and reporting; a messaging provider can be integrated, and scope follows the jurisdiction's operating model.
Fee and limit engine
Maker/taker fees, KYC-tier limits, asset and network rules, and segment-based fee structures are managed centrally.
Back office and reporting
Customer, wallet, trade, fee and limit administration with role-based permissions, audit history and exports for auditors and supervisory review.
Performance
Engineered for High Order Throughput
up to 700,000 orders / second
Matching-engine capacity measured under defined test conditions
A matching engine tested at up to 700,000 orders per second. The figure reflects defined test conditions rather than continuous production throughput; capacity for each deployment is planned around hardware, network and trading profile, and validated through load testing.
Technical Structure
Built for Production Conditions
The platform is designed around high availability, horizontal scaling and observability requirements. The engineering approach — languages, data layer, messaging and deployment — is described on the technology page.
-
Event-driven financial workflows
High-volume financial workflows are coordinated through event and messaging systems rather than depending on one synchronous application path.
-
Web, iOS and Android applications
Registration, KYC, portfolio, trading, deposits and withdrawals, and security settings are delivered through web and mobile applications customised to the customer's brand.
-
Central monitoring and audit records
Customer, administrator, financial and system events can be centrally monitored and reported for operations and audit.
-
Continuity and recovery
Backup is designed together with restore testing, RTO/RPO planning and alternative operating environments.
-
Multi-chain network support
Bitcoin, Ethereum, Solana, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Tron, Polkadot, Near, Cosmos and Aptos are supported or integration-target networks; exact token and asset coverage is validated per deployment.
Regulatory Context
Regulation Starts in the Architecture
The exchange software is structured around the customer's regulatory framework, with the United Kingdom and the European Union treated as distinct implementation programmes. Readiness work is technical and operational preparation; it is not legal advice and does not amount to authorisation.
Explore regulatory readiness-
United Kingdom
We prepare the technology, records, AML/KYC workflows and operating controls required to support a UK cryptoasset business through the current MLR framework and the transition to the incoming FSMA regime.
-
European Union
The MiCA transition has ended. New EU cryptoasset projects must be designed for an authorised CASP operating model from the beginning. The platform and its operating evidence embed DORA requirements into the technology lifecycle rather than treating them as a separate policy exercise.
Deployment
Customer-Specific Deployment
The platform is not locked to one cloud provider; deployment follows the customer's regulatory, data-residency, cost and operating requirements. In source-code engagements, the customer can select and contract its own servers, cloud or data-centre provider, while installation, environment configuration and handover are delivered by Grumpio. Infrastructure ownership and managed-service responsibilities are separated in the contract.
On-premises and dedicated
Installation on customer-selected servers or dedicated infrastructure, configured around the data-residency requirements of the operating jurisdiction.
Private and public cloud
Deployment on the preferred cloud provider with environment separation, secrets management and security configuration.
DevOps and handover
Containerised deployment, CI/CD, logging and backup form part of the installation, together with training for the customer's operating team.
Commercial Model
White-Label and Source-Code Models
The same platform is offered through two principal models, selected around internal engineering capacity, data residency, intellectual-property expectations and the intended support model. A white-label engagement launches from an established platform under licence, while the source-code enterprise model licenses the code to a named legal entity for internal development. Final rights and delivery scope in either model are contractual.
| Scope | White-Label | Source-Code Enterprise |
|---|---|---|
| Starting model | Launch from an established platform under a monthly or annual licence | Source code licensed to a named legal entity |
| Customisation | Brand identity, module selection, fee and limit configuration, provider integrations | Full source-code access for internal development; independent resale is not permitted |
| Data and hosting | Customer-controlled infrastructure where legally and technically appropriate | Customer-selected servers, data centre or cloud provider |
| Delivery scope | Installation, training, ongoing support and updates | Source code, deployment assets, technical documentation and handover training |
| Transition | An option to acquire the source code under defined commercial terms | Contractual transferability with the sale of the legal entity |
Integrations
Integration Categories
The platform connects to the business's current and planned provider ecosystem; integration scope is defined per project, in line with provider agreements and the authorised operating model.
- Banking and fiat: bank transfers, vIBAN providers and multi-currency flows.
- KYC and AML providers: Legichain or customer-selected providers; multi-provider use is supported.
- Liquidity providers: market-data feeds, order routing and reconciliation connections.
- Custodians: third-party custodian and wallet-infrastructure integrations.
- Blockchain networks: multi-network connectivity through nodes and RPC providers, with a fallback model supporting continuity.
FAQ
Frequently Asked Questions
The platform combines spot trading, the matching engine, wallets, ledger, fiat deposits and withdrawals, AML/KYC integrations, Travel Rule support, fee and limit management, back office, reporting, and web and mobile applications in one system. Module scope is configured per project around the operating model and jurisdiction.
In the white-label model, an established platform is customised to the customer's brand, fee structure and integrations under a licence model. In the source-code enterprise model, source code, deployment assets, technical documentation and handover training are delivered under a licence to a named legal entity; independent resale is not permitted.
In the United Kingdom, the platform supports the current MLR framework and the transition to the incoming FSMA cryptoasset regime, including financial-promotion journeys and Travel Rule workflows. In the European Union, the MiCA transition has ended and the platform is structured around an authorised CASP operating model, with DORA treated as a current operating framework. This is technical and operational preparation, not regulatory approval or authorisation.
Wallet infrastructure is configured around hot, cold and multisignature models, with HSM and separated key-management options, adapted to the customer's operating and risk model. Third-party custodian integrations can be added to the project scope.
Deployment is selected around regulation, data residency and operating requirements: on-premises, private cloud, the preferred cloud provider or a dedicated data centre. Installation, CI/CD, logging and backup are configured within the project scope.
Maintenance, defect resolution, regular releases, new module development, infrastructure support, incident response and regulation-driven changes continue under the support model defined in the contract, together with operations and engineering-team training.
