Abstract

The 2024 collapse of Synapse Financial Technologies revealed systemic vulnerabilities within the fintech sector, particularly the operational and legal risks arising from reliance on third-party service providers. This article critically examines these risks through a case study inspired by real-world practice involving Lyntera Pte Ltd, a Singapore-based cryptocurrency exchange, and Valderix AG, a Swiss blockchain infrastructure provider. The dispute illustrates how software-as-a-service (SaaS) arrangements can result in a disjunction between legal ownership and practical (technical) control, where service providers retain unilateral authority over access to digital assets and core systems. By analysing the contractual, jurisdictional, and procedural dimensions of the Lyntera-Valderix scenario, the article identifies key vulnerabilities inherent in custodial models and the limits of enforceability in cross-border digital asset disputes. It evaluates urgent legal remedies, such as emergency arbitration, interim court measures, and proprietary claims under both Singapore law and Swiss law. The article also considers the emerging recognition of digital assets as proprietary objects. The article concludes by proposing preventive contractual and technical safeguards to recalibrate control and mitigate dependency risk, thereby contributing to the broader discourse on digital asset governance and fintech operational resilience.
