BlackRock's BUIDL fund goes live on Tempo blockchain
DeFi & Yields ·
The tokenized Treasury fund now lets eligible users on Stripe's payments chain convert idle stablecoin balances into yield-bearing shares without leaving on-chain workflows.
BlackRock's tokenized Treasury fund, BUIDL, is now live on Tempo, a payments-first blockchain incubated by Stripe and Paradigm, according to a post on X. The integration gives eligible users a mechanism to move idle stablecoin holdings into yield-bearing fund shares while remaining within on-chain workflows, rather than routing through off-chain custodial steps.
Securitize supplies the tokenization and transfer agent infrastructure underpinning the fund's presence on Tempo, handling the issuance and administrative rails that let BUIDL shares exist and move on the network. RedStone, meanwhile, feeds daily on-chain valuation and interest accrual data, a function needed for a Treasury fund whose share price and yield must update reliably for on-chain consumption.
The move fits into a broader pattern described across the cluster: Tempo is expanding its on-chain yield offerings by adding BUIDL as a destination for stablecoin balances, with several accounts characterizing the fund as a $2.6 billion tokenized money market product now reachable from Tempo's Layer 1 environment. That framing points to BUIDL's scale as a factor in why its arrival on a payments-focused chain is being treated as notable — it extends an established institutional Treasury product into a blockchain built specifically around payment use cases.
Multiple accounts covering the story converge on the same three infrastructure pieces: Tempo as the settlement layer, Securitize as the tokenization and transfer agent, and RedStone as the oracle supplying valuation and accrual data. That consistency across separate write-ups suggests the technical description of the integration — fund access via Securitize rails, pricing via RedStone feeds — is the agreed-upon shape of the launch, even though the underlying reporting traces back to a single detailed account of the mechanics.
What remains unspecified is which categories of users qualify as "eligible" to access BUIDL shares through Tempo, and whether there are minimum balance thresholds, geographic restrictions, or onboarding requirements tied to the fund's existing eligibility rules. Also unaddressed is the timeline for broader rollout on Tempo, whether other tokenized Treasury or money market products will follow the same Securitize-plus-RedStone template, and how yield generated through the integration will be reported or taxed for participants. Further detail on adoption figures or transaction volume since launch has not yet surfaced.
