Market model
Define products, order states, fees, throughput and the authority that matches orders.
Exchange platforms around orders, balances and control.
Build digital-asset trading workflows with deterministic ledgers, custody boundaries, reconciliation, operator approvals and visible market operations.

Tools & technologies
- TypeScript
- Event-driven services
- PostgreSQL
- Redis
- Streaming infrastructure
- Custody APIs
- Observability
Set the operating boundaries before matching orders.
External dependencies
Map identity, liquidity, market data, custody and reporting providers to their failure and recovery paths.
Owner responsibilities
Licensing, market access and custody approval remain with the accountable business owners.

Part of an order fills. The rest can be cancelled.
Read this example
Place a sample order for 10 units.
- Order accepted. Funds for the sample order are reserved in the internal ledger. Open quantity: 10.
- Partial fill recorded. Four units match. Six remain open. Filled: 4 · remaining: 6.
- Remainder cancelled. The open six units are cancelled and their unused reservation is released. Filled quantity remains 4.
Cancellation affects the unfilled remainder while completed fills remain recorded.

The detail behind delivery.
Delivery stages
Market and balance model
Specify products, order states, fees, accounts and balance movements.
Custody and authority boundaries
Separate signing, withdrawal, operator and provider responsibilities.
Trading and ledger architecture
Design order, matching, ledger, settlement and event boundaries.
Platform implementation
Build customer journeys, services, administration and integrations.
Reconciliation and release
Test concurrency and failure, then monitor market and custody health.
Technology and integration options

- Event-driven services
- PostgreSQL
- Redis
- Streaming infrastructure
- Custody APIs
- Observability
Scope dependencies and operating risks
Delivery depends on
- Market, order and fee decisions
- Custody, identity and liquidity dependencies
- Ledger, security and regulatory review ownership
Review before release
- Order and balance transitions are deterministic
- Custody and operator authority use separated approvals
- Ledger, custody and customer balances are reconciled
A few practical questions.
When is Exchange Development a good fit?
It fits a defined digital-asset market with accountable custody, operating and regulatory owners and clear order and settlement rules.
Which technical decisions matter first?
Market model, order types, matching authority, custody, internal ledger, identity controls and reporting matter first.
Can it connect to our existing systems?
Yes. Custody, identity, liquidity, market data and reporting services can be connected through validated, observable boundaries.
How is the work tested?
Concurrency, order transitions, partial execution, ledger invariants, provider failures, withdrawals and reconciliation are exercised.
What do you need before starting?
We need the market and fee model, asset scope, custody plan, identity requirements, expected throughput and operating owners.
What affects the delivery timeline?
Market types, matching throughput, custody, asset coverage, identity controls, migration and operating responsibilities drive scope.
Start with the market and balance rules.
Bring order types, fees, asset scope, custody providers, identity requirements and operating owners.
