Securitize has integrated Wormhole as its official blockchain interoperability provider for all tokenized assets, according to a Sept. 20 announcement. This collaboration enables cross-chain capabilities for current and future assets tokenized through the Securitize platform.

Notably, Securitize is the company providing the infrastructure for BlackRock’s foray into tokenized US Treasuries through its BUIDL fund. Currently, BUIDL is the largest tokenized fund in the US, with over $520 million in market cap, according to RWA.xyz‘s data.

“Tokenized securities need to thrive on public, permissionless blockchains to unlock the potential of blockchain technology,” Carlos Domingo, CEO and co-founder of Securitize, stated.

Domingo added that the partnership is important to enable Securitize to transition into a cross-chain ecosystem, which showcases how public blockchains enable new use cases that had previously been unavailable.

Thus, the integration allows tokens to move across different blockchain ecosystems, enhancing liquidity and accessibility for tokenized assets.

Securitize will use its own smart contracts in a customized approach, allowing for tailored solutions that meet specific asset manager needs and regulations while leveraging the Wormhole messaging protocol.

“Securitize has solidified itself as a leader in the tokenized asset ecosystem and we’re thrilled to bring the Wormhole platform to their customers to enable a more complete asset management experience,” Robinson Burkey, co-founder and CCO of Wormhole Foundation, added.

Burkey also highlighted that this prepares the ground for increased institutional adoption of tokenized assets, allowing the bridging of the massive traditional finance market to decentralized finance.

According to Wormholescan’s data, Wormhole’s interoperability infrastructure moved nearly $47.7 billion across chains since its deployment.

Over $2 billion divided into different blockchains

The tokenized US Treasuries market surpassed $2.2 billion in 2024, after registering a 187% year-to-date growth, according to data from RWA.xyz.

Despite Ethereum holding most of the market size, with over $1.6 billion of tokenized real-world assets deployed on its infrastructure, significant liquidity is fragmented over different ecosystems, which makes the case for a cross-chain interoperability solution in this sector.

Stellar holds $422 million in tokenized US Treasuries, followed by Solana’s $69 million market size. Arbitrum and Mantle also hold $39 million and $27 million in market size, respectively.
