• Calastone starts on-chain fund distribution through Polygon, speeding settlement and trimming operational costs.
  • Tokenized share classes on Polygon widen investor access and boost transparency across global markets.

Calastone, the world’s largest funds network processing more than £250 billion each month, has introduced tokenized fund share classes on Polygon . The launch links 4,500 financial institutions across 58 markets, setting a new milestone for blockchain use in global fund operations.

The integration allows asset managers to issue and manage fund share classes directly through blockchain systems while keeping the same compliance and administrative practices they already follow. The move aims to simplify settlement and cut costs across borders, powered by Polygon’s low transaction fees and instant processing speeds.

Adam Belding, Chief Technology Officer at Calastone, said, 

Calastone Tokenised Distribution offers asset managers a powerful new route to market. We make it possible to distribute existing funds via blockchain networks, instantly and at scale, without any operational upheaval or technical reinvention.

The world’s largest funds network, processing £250B+ monthly chooses Polygon to launch tokenised fund share classes to 4,500 financial institutions in 58 markets.

Faster Fund Distribution through Polygon

The partnership delivers a model for how fund tokenization can streamline global asset distribution. By running operations on Polygon, Calastone removes several intermediary layers, leading to faster transactions and improved transparency, all without affecting regulatory compliance or custody standards.

Polygon’s scalability and Ethereum compatibility make it suitable for large institutions aiming to adopt blockchain-backed solutions. Its system processes transactions at sub-cent fees and achieves near-instant finality, helping firms achieve smoother cross-border operations.

The shift also extends new opportunities to both institutional and retail investors. Fund managers gain access to digital-native investor bases globally, while blockchain automation cuts down the time needed for reconciliation and settlement.

Calastone’s initiative reflects a growing movement of traditional financial markets migrating toward open and public blockchain systems. Polygon’s recent Rio and Heimdall upgrades , which enable transaction speeds of up to 5,000 per second, further strengthen its role as a trusted network for large-scale fund transfers and tokenized assets.

Additionally, a recent Calastone report estimated that tokenization could save the asset management sector about $135 billion every year by reducing operational costs and speeding up fund launches. These savings also help cut seed capital needs, making fund creation more accessible.

Julien Hammerson, CEO of Calastone, noted,

The investment world is changing fast. New pools of capital are forming on blockchain networks, and they are not being accessed through traditional channels. Our Tokenised Distribution solution gives asset managers instant reach into these markets, without the requirement or need for transformation. We are making it easy to evolve with the market.

Calastone’s Tokenised Distribution platform is already active, with further network features expected to roll out during 2025. The expansion marks a key stage in Calastone’s broader vision to shift traditional fund management toward blockchain infrastructure.
