Crypto and digital-asset exchanges hold bearer value that moves irreversibly — which turns every unpatched gap into a direct loss. We secure the platform, engineer the fraud controls, and trace the money on-chain when something moves. We build and trace, not just advise — and we find the holes the Big 4 don't.
A digital currency exchange (DCE), trading venue or brokerage sits at the on-and-off ramp between the crypto economy and the banking system. That position concentrates two hard problems at once: securing infrastructure that holds bearer assets, and policing value that can leave the platform in seconds and never come back.
Credential stuffing, phishing, SIM-swap and session hijacking aimed at draining customer accounts — the single most common way real money leaves an exchange.
Key management, signing infrastructure, wallet architecture and the exchange stack itself — where a single flaw can mean an unrecoverable, catastrophic loss.
Fake deposits, chargeback and refund abuse on fiat rails, mule networks and withdrawal-address swaps that move funds before anyone notices.
Inbound and outbound exposure to sanctioned addresses, darknet markets, ransomware wallets and scam proceeds that never appears in your fiat data.
Tumblers, cross-chain bridges and rapid asset-hopping designed to break the link between source and destination and defeat naive tracing.
Wash trading, spoofing, layering and insider activity on the order book — the exchange-native equivalent of securities-market manipulation.
Engineering-led work for exchanges, DCEs, securities venues and brokers — from securing the platform to tracing stolen assets across chains. Every engagement ends in a working control or a traced result, not a report you have to action yourself.
On-chain analytics is the core of a modern exchange defence, and it is where we spend a lot of our time. We cluster and attribute addresses, screen wallets against high-risk categories — sanctioned addresses, mixers, darknet markets, ransomware and known scams — and trace the flow of value across wallets and chains. For your platform that means screening deposit and withdrawal counterparties before you credit or release funds, feeding wallet-risk into how you rate and monitor each customer, and reconstructing the path of stolen or laundered value when a suspicion forms. When funds are chain-hopped or pushed through a tumbler, we follow them through it rather than stopping at the first hop.
An exchange has two ledgers to watch, and most only watch one properly. We build and tune monitoring across both — the off-chain fiat rails (deposits, withdrawals, velocity, structuring across linked accounts) and the on-chain movements (counterparty wallets and their exposure) — and, critically, we join them together so an on-chain signal can raise an off-chain customer's risk and vice versa. We tune the rules to real crypto typologies so you catch what matters without drowning your team in false positives.
We engineer the detection logic that stops deposit fraud, withdrawal fraud and account-draining before settlement — scoring models, velocity and anomaly rules, device and behavioural signals, and step-up controls at the moments that matter. Because crypto settlement is final, the design goal is to catch and hold in real time, not to reconcile a loss after it has left the building.
Bank-grade security for infrastructure that holds bearer assets. We penetration-test the exchange application, APIs, wallet and signing infrastructure, and cloud environment; review key management and hot-wallet architecture; and harden the systems that move and hold funds. This is adversarial, hands-on testing of the specific attack surface an exchange presents — not a checklist run against a generic web app.
When the off-the-shelf tools don't fit your money flows, we build. Bespoke fraud and risk engines, wallet-screening and address-risk services, monitoring and tracing tooling, and internal case-management — engineered for your platform and integrated with your stack, not bolted on as another dashboard nobody reads.
When an exchange is breached or a customer is drained, speed decides how much you recover. We contain the incident, investigate how it happened, and trace the stolen assets on-chain — across wallets, chains and mixers — to support recovery efforts and law-enforcement referrals. Then we close the hole so the same route can't be used twice.
Our centre of gravity is security, fraud and tracing — but we can support the AML/CTF side too. Where it helps, we tune monitoring so it satisfies AML obligations as well as fraud, and we support AUSTRAC-related reporting and reviews. For the full compliance picture, our guide to AUSTRAC AML for Australian crypto exchanges (DCEs) walks through registration, programs and reporting in depth. The point stands: the AML overlay only works on top of controls that actually work — so we start with the technical holes.

Learn moreA crypto exchange holds custody of bearer assets that move irreversibly, which turns ordinary security gaps into direct losses. The distinctive risks include hot-wallet and key-management compromise, account takeover through credential stuffing and SIM-swap, deposit and withdrawal fraud, on-chain exposure to sanctioned addresses, mixers and scam wallets, and market abuse on the trading engine. Because settlement is final, prevention and fast detection matter far more than recovery.
Blockchain tracing follows the flow of funds across wallets and chains using on-chain analytics — clustering addresses, attributing them to known entities and scoring exposure to high-risk sources such as sanctioned addresses, mixers, darknet markets, ransomware and scams. An exchange uses it to screen deposit and withdrawal counterparties before crediting or releasing funds, to feed wallet-risk into customer risk ratings, and to reconstruct the path of stolen or laundered value during an investigation.
We build and we trace — we do not stop at a slide deck. We engineer fraud-detection logic, tune on-chain and off-chain transaction monitoring, penetration-test exchange and wallet infrastructure, and write custom security software that integrates with your platform. Advisory is part of the work, but the deliverable is a working control, not a recommendation you have to implement yourself.
Yes. We provide incident response for exchange breaches — containing the compromise, investigating how it happened, and tracing the movement of stolen assets on-chain across wallets, chains and mixers to support recovery efforts and law-enforcement referrals. We also harden the platform afterwards so the same hole cannot be used twice.
We can support the regulatory side, but security and fraud engineering is our centre of gravity. Where you need it, we help tune transaction monitoring so it satisfies AML obligations as well as fraud, and we support AUSTRAC-related reporting and reviews. Our starting point is finding and closing the technical holes — the AML overlay sits on top of controls that actually work.
