BlackRock's BUIDL fund expands to Tempo, its 10th blockchain
DeFi & Yields ·
The $2.64 billion tokenized Treasury fund now integrates with a payments-focused chain, adding institutional yield to a network built for stablecoins and treasury workflows rather than speculative trading.
BlackRock's BUIDL, a tokenized fund representing shares in a U.S. Treasury portfolio, went live on Tempo, marking its 10th blockchain deployment, according to a post on x.com. The fund holds $2.64 billion in assets under management, up 18% over the last 30 days, and currently offers a 3.40% 7-day APY. BUIDL is backed by cash, U.S. Treasury bills, and repos, and carries a Moody's AAA-mf rating.
The expansion lets investors earn Treasury-backed yield on idle stablecoin holdings without exiting onchain environments. Rather than another speculative token listing, BUIDL functions as a claim on a regulated Treasury fund, positioning it as a yield-bearing instrument for institutional and onchain treasury management alike.
Tempo's design choice is central to the launch. The chain is built specifically for payments, treasury operations, stablecoins, and tokenized deposits, rather than general-purpose DeFi speculation, making it a fit for a product like BUIDL that is meant to plug into real-world financial workflows. The integration also marks Securitize's first deployment on Tempo; Securitize provides the regulated infrastructure underlying BUIDL, handling tokenization, investor onboarding, transfer services, and ownership records that connect the fund to blockchain rails.
Pricing and valuation for the fund on Tempo are supplied by RedStone, whose oracle feeds enable daily valuation, interest accrual, and composability with other DeFi applications on the network. Together, four providers now form the stack behind the deployment: BlackRock supplies the underlying Treasury fund, Securitize tokenizes and administers it, RedStone delivers valuation data, and Tempo provides the payments and treasury infrastructure that carries it onchain.
The move comes as the broader tokenized U.S. Treasury market has grown to between $13.5 billion and $16 billion, reflecting rapid expansion in institutional real-world asset products. Notably, Tempo itself remains a comparatively small network, with roughly $28 million in total value locked and about $43 million in stablecoins, yet it has now secured one of the largest tokenized Treasury funds in crypto.
What remains unclear is how quickly BUIDL's yield and liquidity will be adopted across Tempo's existing stablecoin and payments activity, and whether the chain's limited TVL will constrain the fund's onchain composability despite RedStone's oracle support. The broader question raised is not whether more assets move onchain, but whether infrastructure like this makes them usable across financial systems at scale.
