Calastone Expands Fund Distribution via Polygon
Calastone, the world’s largest funds distribution network, has announced its integration with Polygon, marking a major step toward tokenizing global fund transactions. The initiative will enable over 4,500 financial institutions across 58 markets to access onchain fund distribution, enhancing efficiency and transparency in asset management.
Processing more than £250 billion in monthly transactions, Calastone connects leading banks, asset managers, and financial intermediaries worldwide. The integration with Polygon’s proof-of-stake blockchain allows the network to modernize fund transfers and settlements using tokenized infrastructure while maintaining existing compliance and regulatory standards.
Tokenized Funds Reach Global Institutions
By launching tokenized fund share classes on Polygon, Calastone aims to streamline fund management and open access to blockchain-powered efficiencies. The platform’s existing network of financial institutions will now be able to benefit from faster settlements, reduced operational costs, and improved cross-border reconciliation.

According to Polygon Labs, the integration enables asset managers to distribute tokenized funds to digital-first investors globally. Blockchain-based automation will help reduce intermediaries and simplify settlement processes while maintaining full transparency across jurisdictions.
The move is expected to support both institutional and retail investors, bridging the gap between traditional fund operations and onchain infrastructure.
Polygon’s Infrastructure Powers Tokenization
Calastone selected Polygon due to its scalability, sub-cent transaction fees, and near-instant finality. With the network’s Rio and Heimdall upgrades, Polygon can process up to 5,000 transactions per second, offering the reliability and speed required for institutional adoption.
This level of performance aligns with the growing push among global financial institutions to tokenize real-world assets (RWAs) and bring traditional markets onchain. The integration also demonstrates how blockchain technology can improve the liquidity and accessibility of regulated investment products.
Polygon’s ecosystem continues to expand, with integrations across major financial and fintech platforms, including Stripe, Manifold Trading, and NRW.BANK. The company is also developing Agglayer, a unified network of interconnected chains aimed at enhancing scalability for large-scale enterprise use.
A Step Toward the Future of Asset Management
The collaboration between Calastone and Polygon highlights a wider trend in the financial sector traditional capital markets increasingly turning to blockchain to reduce friction and modernize infrastructure.
By tokenizing fund share classes, Calastone will enable programmable fund operations, instant reconciliation, and seamless investor onboarding. This transition could serve as a model for how asset managers and custodians integrate blockchain technology without disrupting existing regulatory frameworks.
Industry analysts say the integration demonstrates blockchain’s potential beyond cryptocurrencies, offering real-world utility in fund management, settlement systems, and cross-border financial operations.
