LMAX Group has launched Kiosk, a hosted interface designed to allow brokers and other institutional clients to accept digital assets from their customers, hold them in LMAX Custody and post those assets as margin across the group’s wider trading venues.
The new product, announced on Tuesday, sits on top of LMAX Group’s existing regulated infrastructure and is delivered as a single, broker-branded portal. According to the firm, clients can deposit crypto into LMAX Custody and immediately use those balances as collateral to trade spot FX, precious metals, digital assets, contracts for difference (CFDs) and perpetual futures.
Functionality and workflow
Kiosk is structured as an integrated interface that bundles several operational functions into one workflow. The portal supports deposits and withdrawals, API credential management, WalletConnect connectivity, security controls and cross-asset treasury management. By consolidating these features, the product is intended to streamline how brokers manage customer digital assets and related collateral across multiple asset classes.
The interface leverages LMAX Custody for safekeeping of digital assets, with those balances then usable as margin across LMAX Group’s trading venues. The group’s offering includes trading in spot FX, precious metals, digital assets, CFDs and institutional perpetual futures.
Early adoption and relationship with BlackBull Markets
BlackBull Markets is among the first brokers to adopt Kiosk. LMAX Group holds a roughly 20.8% stake in the New Zealand-headquartered multi-asset broker, acquired in 2024 as part of a partnership. BlackBull Markets is currently running an initial public offering roadshow targeting a dual listing on the Australian Securities Exchange (ASX) and the New Zealand Exchange (NZX), and reports monthly client trading volume of close to $200 billion.
Strategic context within LMAX Group
Kiosk is described as the latest element in a multi-year build-out at LMAX aimed at positioning the group in the middle of the traditional finance and crypto stack. As part of this strategy, the group launched institutional perpetual futures on BTC/USD and ETH/USD in September 2025, offering leverage of up to 100x.
LMAX Group did not disclose how many institutions had committed to the Kiosk product at launch, nor did it provide any pricing details.
