BlackRock has expanded its tokenised money market fund, the BlackRock USD Institutional Digital Fund (BUIDL), to the Solana blockchain. This strategic move is facilitated in collaboration with BlackRock’s blockchain partner, Securitize. The BUIDL fund, currently holding $1.7 billion in cash and treasury bills, is expected to exceed $2 billion by April. This expansion follows BUIDL's selection to tokenise half of Spark’s $1 billion real-world asset fund. The initiative highlights the growing interest in leveraging on-chain assets for enhanced accessibility, with other financial giants like Franklin Templeton also exploring similar avenues.
