About Libeara

Libeara is rebuilding capital markets on-chain through its compliance-first approach to the tokenisation of real-world assets. The company is backed by SC Ventures, the innovation arm of Standard Chartered, whose mission is to rewire the DNA of banking.

To date, Libeara’s infrastructure has supported the tokenisation of more than US$1 billion in regulated assets - including a top-rated tokenised U.S. Treasury fund and the first tokenised retail money market fund in Asia. With multi-chain interoperability and institutional-grade security and governance, Libeara is scaling access to real-world assets the right way - transparent, regulated, and on-chain.
