BondbloX, a fractional bond exchange that uses distributed ledger technology (DLT), has completed a $6 million Series B financing round with participation from Beacon Venture Capital under KBank, Citigroup, MassMutual Ventures, Potato Productions, and Octava. BondbloX uses the Hyperledger Sawtooth enterprise blockchain to acquire traditional bonds and split them, allowing investors to purchase amounts as low as $1,000. BondbloX was launched in 2020 and was only opened to professional and qualified investors until last month, and is now open to retail investors.
