September 17, 2025 — Banco Santander’s digital banking arm, Openbank, has launched Polygon trading in Germany, giving retail customers access to POL alongside Bitcoin, Ethereum, Litecoin, and Cardano. The service will soon expand to Spain, bringing Polygon to millions of European users under full MiCA investor protections.
The rollout comes under the European Union’s Markets in Crypto-Assets (MiCA) regulation, which enforces strict licensing and investor protection. This ensures that assets like Polygon (POL) traded on Openbank benefit from robust compliance measures.
Santander’s compliance with MiCA sets it apart as a trusted gateway for retail crypto adoption in Europe. The integration demonstrates institutional confidence in Polygon’s Layer 2 scaling solutions, which already support thousands of decentralized applications.
Polygon has become one of the most widely adopted Ethereum scaling solutions, known for zkRollups, Plasma chains, and its zkEVM. By offering high throughput at low costs, it powers over 1,000 DeFi and NFT projects.
Analysts suggest that Santander’s decision to include POL with top digital assets could boost Polygon’s market capitalization, currently $10 billion, by as much as 20%.
Banco Santander, one of Europe’s largest banks, is leveraging Openbank’s 2 million-strong user base to bring crypto closer to traditional finance. With fees of 1.49% per trade and no custody costs, the offering lowers barriers for retail adoption.
The move continues Santander’s broader digital asset strategy, which includes prior experiments with stablecoins and regulatory licenses. As Openbank expands its portfolio and introduces inter-crypto conversions, Polygon is positioned to benefit from rising demand in regulated markets.
By adding Polygon trading in Germany, Santander’s Openbank has taken a major step toward institutional adoption of Layer 2 solutions. With Spain next in line, millions more will gain access to POL under Europe’s robust regulatory framework, marking a milestone for both Polygon and the broader crypto industry.
