Digital asset custody: hot, warm and cold, and the controls between them
Losses at exchanges and custodians rarely come from broken cryptography. They come from weak controls around keys, approvals and withdrawals.
Trading Platforms
Trading infrastructure for brokers, exchanges and institutional desks, covering order entry, matching, liquidity and market surveillance.
Overview
Trading floors like the one in the photograph have mostly gone quiet; the activity now happens inside matching engines and order-management systems. We build and integrate those systems for securities brokers, commodity and FX desks and digital-asset exchanges: the customer front end, pre-trade risk checks, the order book and the back-office link to clearing and custody.
Surveillance is part of the scope from the start. Regulators expect a broker or exchange to detect spoofing, wash trades and unusual patterns, and to show how each alert was handled. We deliver the detection rules and the case-management screens compliance officers work in.

PCI DSS v4: what changed for merchants and acquirers
The requirements that were "best practice" until March 2025 are now mandatory. Most of them land on payment pages, authentication and the way risk is documented.

ISO 20022 and the remittance counter: what exchange houses need to change
Cross-border payment messages have moved to ISO 20022. The richer data only helps if it is captured correctly at the counter and in the app.
