Paribu Custody introduced its technology and platform capabilities at the Paribu Custody Product Showcase held at Paribu Art on Thursday, April 16, 2026.
Hosted by Paribu Founder and CEO Yasin Oral, the event presented ColdShield®, the custody architecture developed by Paribu engineers, along with hands-on demonstrations of Paribu Custody’s core capabilities. Combining HSM, MPC and Secure Enclave technologies in a robust architecture, ColdShield® was positioned as the foundation of Paribu Custody’s security model.
Digital sovereignty is becoming a strategic priority
The event opened with remarks by Cem Sağlam, Head of Institutional Sales and Business Development at Paribu Custody. In his speech, Sağlam underlined the growing importance of digital sovereignty across critical sectors such as defence, telecommunications, renewable energy and finance. He also referred to regulatory requirements for crypto asset service providers and highlighted tokenized real-world assets as a growing trend in traditional finance. As of April 2026, the market size of tokenized real-world assets exceeded USD 28 billion, while projections for 2033 point to a market of USD 18.9 trillion.
Core platform capabilities were presented through practical use cases
Ahmet Mesut Şahinoğlu, Engineering Manager at Paribu Custody, presented the technical foundations of ColdShield®. He noted that Paribu did not outsource its custody technology or security layer to third parties, and instead developed its own infrastructure in-house. He also stated that the custody technology has completed SOC 1 and SOC 2 audits and holds ISO 27001 certification.
The product presentation highlighted capabilities including segregated wallets, real-time asset visibility, fee and off-chain nonce management, role-based access control, Admin Quorum, policy management and approval flows. Platform-level features such as Travel Rule compliance through ClearTX, support for more than 80 networks and staking integration were also introduced.
Authorization, integrity and proof at the core of the architecture
During the technical session, Paribu Custody’s approach to core custody challenges was explained under three areas: authorization, integrity and proof. The roadmap for the post-quantum era was also referenced, particularly in relation to elliptic curve cryptography, which underpins major blockchain networks.
Following the break, participants were introduced to both custodian and institutional client workflows through a hands-on session led by Senior Product Manager Büşra Kırıkcı and Engineering Manager Ahmet Mesut Şahinoğlu. The session covered workspace setup, user onboarding, vault creation and policy configuration on the custodian side, followed by practical demonstrations of address declaration, asset listing, allowlisting, balance transfers, AML and staking features.
Closing remarks
The event concluded with remarks by Abdulkadir Kahraman, General Manager of Paribu Kripto Varlık Saklama Kuruluşu A.Ş. Referring to recent developments in global digital asset custody, he closed by emphasizing the role of domestically developed custody infrastructure in both local and international markets. Kahraman invited stakeholders across finance, public institutions and civil society to help build Türkiye’s digital asset infrastructure together.
