Calastone Brings Global Fund Distribution Onchain with Polygon

tl;dr

• Calastone, with £250B+ monthly, will launch tokenized fund share classes on Polygon
• Integration brings onchain fund distribution to 4.5k financial institutions in 58 markets
• Polygon’s sub-cent fees and near-instant finality make large-scale institutional settlement practical onchain
• Calastone is a major step toward bringing onchain capital markets built on scalable, transparent infrastructure

Calastone, the global funds network that processes more than £250 billion in transactions each month, is launching its tokenized fund distribution solution on Polygon, the go-to stack powering global money movement, supporting sending billions in value, instantly. 

The integration brings institutional-scale fund distribution onchain, enabling asset managers to operate fund share classes directly over blockchain rails while maintaining the administrative and compliance processes they already use. 

For Calastone’s network of 4,500 institutions across 58 markets, this means faster settlement, lower costs, and programmable efficiency, all backed by Polygon’s stable scalability, sub-cent transaction fees, and near-instant finality.

This marks one of the first large-scale integrations of blockchain into global fund infrastructure. Calastone’s adoption of Polygon provides a model for how tokenization can modernize asset distribution. With Polgyon’s rails, Calastone reduces intermediaries, expands cross-border access, and enhances transparency without disrupting compliance or custody standards.

Polygon delivers the scale, Ethereum compatibility, and cost efficiency that global institutions need to operate onchain, without sacrificing trust or performance.

By launching tokenized fund share classes on Polygon, Calastone unlocks new pathways for both institutional and retail investors. Asset managers can reach digital-first investor pools globally, while blockchain transparency and automation simplify settlement and reconciliation across jurisdictions.

The integration also signals a broader shift underway: the migration of traditional capital markets onto public, open infrastructure. As Polygon’s Rio and Heimdall upgrades bring speeds of up to 5,000 TPS and instant finality, the network continues to position itself as the go-to chain for institutional-grade payments and tokenized assets.

Calastone’s Tokenised Distribution is now live, with expanded functionality and network integrations planned throughout 2025, a milestone that takes a major step to bring the future of fund management onchain.
