The Challenge
Bitbuts came to us with a clear ambition: stand up a credible multi-asset trading platform for the Canadian market, built to the engineering standard that traders actually expect rather than to the lower bar most regional retail platforms quietly settle for. The team had the market thesis, the relationships, and the regulatory pathway already in motion — what they needed was an engineering partner who could ship the platform itself without cutting corners on the parts that matter most under load.
The brief carried real constraints. Order placement and management had to feel tight under live market conditions, market data and charts had to update in real time without the UI thrashing, KYC onboarding had to satisfy Canadian regulatory expectations end-to-end, and the custody integration had to be safe enough that the operations team could trust the system with real customer balances. None of those pieces were optional, and none of them could be papered over with marketing language once the platform was open to actual users.
Our Approach
We architected and built the platform end-to-end. The defining decision was to treat the order path as the system's hot core — every other surface (charts, balances, history, admin) bends around the requirement that order placement, modification, cancellation, and matching/routing logic stay low-latency and predictable under load. That meant a deliberate split between the synchronous order path and the asynchronous reporting and analytics paths, so a spike in chart subscriptions or a slow analytics query could never back up the order queue.
The trading surface itself ships the order types and the order-book interactions traders expect. Market data flows in over WebSockets with a fan-out layer in front so the matching engine never serves chart subscribers directly. The KYC onboarding pipeline is built as a state machine — identity capture, document upload, sanctions screening, and approval — with the operations console giving compliance staff the audit trail they need to defend each decision in the context of Canadian regulatory expectations.
- Order placement & management — market, limit, and stop variants with explicit, traceable state transitions and idempotent cancel/replace.
- Real-time market data & charts — WebSocket-backed feeds with reconnection discipline, snapshot-plus-delta semantics, and a chart layer that survives connectivity gaps.
- KYC onboarding — identity capture, document verification, sanctions/PEP screening, and a reviewable approval workflow for compliance.
- Custody integration — safe boundary between the trading platform and the custody layer, with reconciliation jobs that catch any drift before it compounds.
- Admin console — operations tooling for user management, compliance review, order-book oversight, and the day-to-day work of running a live venue.
We engineered for a sub-200ms p99 latency target on the order path, which forced the kind of architectural discipline — connection pooling, queue topology, careful database access patterns — that doesn't show up in screenshots but defines whether the platform feels real or feels like a demo. The custody integration was treated as a security-first surface, with the reconciliation logic doing the unglamorous load-bearing work of ensuring on-platform balances and custody-side balances stay in agreement at all times.
Stack: Laravel · React · WebSockets · PostgreSQL, deployed on infrastructure sized for live retail-trading load and tuned for the latency profile of the order path.
The Outcome
The platform is live in production serving Canadian customers. Orders flow through the system end-to-end — placed on the trading surface, matched and routed through the order path, settled against custody, and reflected back into the user's balance and history without manual reconciliation. KYC onboarding is operational and the compliance team has the tooling to review and approve users with a defensible audit trail.
Our engagement continues as Bitbuts extends the platform with additional asset coverage and operational depth. The architectural choices made early — separating the hot order path from the analytics and reporting paths, building custody integration as a reconciled boundary rather than a trusted link — have held up under live trading load and gave the team the headroom they needed to grow into the platform rather than around it.
