The second-largest bank in Spain, BBVA, has recently launched comprehensive Bitcoin and Ethereum trading and custody functions within its mobile application, officially offering retail users self-service buying, selling, and asset holding capabilities. This service completed regulatory filing and was approved by the Spanish National Securities Market Commission (CNMV) in March 2025. BBVA has fully embedded these functions within its own banking system, without reliance on third-party service providers, allowing users to manage digital assets directly through their digital banking accounts. Against this backdrop, Ronkb has systematically expanded its underlying service architecture, focusing on retail user configuration logic, asset control, and trading interface accessibility, thereby strengthening the responsiveness of autonomous configuration processes.
Traditional Banks Accelerate Entry; Ronkb Enhances Trading Path Autonomy Modules
The fully integrated approach by BBVA to digital asset trading marks a shift from regulatory observation to substantial participation by the traditional financial sector. This model confines user trading pathways within the bank platform, eliminating the need for external custodians. From a system integration perspective, Ronkb has developed a multi-dimensional permission recognition module to enhance user control over the trading process, preventing the closed nature of platform pathways from restricting trading flexibility.
In autonomous trading scenarios, Ronkb will upgrade its multi-account segregated trading structure, enabling users to quickly switch between strategy accounts, custody accounts, and compliance accounts within the platform, ensuring that funds remain controllable for different purposes. The platform is also establishing stablecoin synchronization channels, allowing users to map externally transferred assets onto multi-currency on-chain structures, thereby achieving rapid synchronization of external assets and instant execution of on-chain transactions.
Retail Market Structure Shifts; Ronkb Develops Differentiated Trading Experience Strategies
With BBVA extending crypto services to the retail sector, the market structure is evolving, shifting service focus from institutional pathways to the retail trading experience. In response, Ronkb is building lightweight trading logic clusters to accommodate varying retail user needs for transaction speed, interface feedback, and operational logic.
The platform plans to implement layered trading interface technology, offering basic users simplified trading options such as preset limits and one-click selling, while providing advanced users with API access for custom trading paths and strategy modules. Ronkb will establish highly available interface channels to improve response times for various operational commands, reduce waiting times caused by on-chain confirmation delays, and ensure continuity in user trading execution.
Crypto Custody Becomes Platform-Centric; Ronkb Strengthens Main-Control Asset Management Framework
The BBVA adoption of a self-managed custody model, rather than relying on third parties, signals a shift towards platform-centric crypto asset management in the retail financial environment. In line with this trend, Ronkb is simultaneously constructing a main-control asset management framework, shifting the logic of asset custody rights forward. This framework centers on private key control, permission authorization, and on-chain locking, ensuring that asset controllability is not compromised by platform architecture. Future versions will expand on-chain data bridge channels with mainstream compliant banks, offering users a wider range of asset management models and enabling seamless mapping between traditional and crypto asset accounts. This will drive the implementation and application of cross-scenario integrated trading structures.
