BlackRock’s USD Institutional Digital Liquidity Fund has expanded to the Tempo blockchain through Securitize, extending the tokenized fund into an ecosystem built around stablecoin payments and financial settlement. BUIDL held approximately $2.64 billion in assets as of July 31, with a net asset value of $1 per share, according to independent data from RWA.xyz.
The integration allows eligible users to convert supported onchain balances into tokenized fund shares without leaving Tempo-based applications and treasury workflows. BUIDL is not itself a stablecoin or a deposit account, but a restricted investment product that seeks U.S. dollar income while maintaining liquidity and stability of principal. Its portfolio is allocated to cash, U.S. Treasury bills and repurchase agreements.

The launch gives eligible users a way to hold stablecoin balances and access yield through tokenized fund shares.

Tokenized Treasury Yield Enters a Payments-Focused Network
Tempo describes itself as infrastructure for real-world payments, with an emphasis on rapid settlement, predictable fees and high transaction throughput. The Layer 1 network was incubated by Stripe and Paradigm and launched its mainnet in March. Adding BUIDL introduces a regulated investment product into the same technical environment used for stablecoin settlement, embedded finance and tokenized deposits.
Tempo's onchain yield offering now includes BUIDL, @BlackRock's USD Institutional Digital Liquidity Fund.
Supported by @Securitize's tokenization infrastructure, with daily onchain valuation and interest accrual via @redstone_defi oracle feeds. Eligible users can access…

For companies developing wallets, payment applications or treasury-management platforms, the integration creates a potential route for moving idle stablecoin balances into an income-producing fund position. The transaction represents a subscription to fund shares rather than interest being added directly to a stablecoin balance, preserving the legal and operational distinction between the payment asset and the underlying investment.
Securitize provides the tokenization and transfer-agent infrastructure supporting BUIDL’s deployment on Tempo. The company’s platform manages investor eligibility, issuance and blockchain-based ownership records, while BlackRock remains responsible for managing the fund’s underlying portfolio. Tempo supplies the settlement network but does not manage BUIDL or guarantee its returns.
RedStone has also deployed two dedicated BUIDL data feeds on Tempo Mainnet. One communicates the fund’s fundamental valuation, while the other tracks daily interest accrual. Both feeds operate with a 24-hour heartbeat rather than providing a continuously changing market price, reflecting the way a fund’s net asset value is calculated off-chain instead of discovered through constant exchange trading.
The oracle infrastructure can make BUIDL’s valuation information available to lending markets and other smart contracts evaluating the shares as collateral. However, an active oracle feed does not automatically make BUIDL acceptable collateral across Tempo’s DeFi ecosystem. Each protocol must separately establish eligibility rules, loan-to-value limits, liquidation procedures and other risk controls before supporting the asset.
Multichain Reach Expands, but Access Remains Restricted
BUIDL originally launched on Ethereum in March 2024 before expanding to Aptos, Arbitrum, Avalanche, Optimism, Polygon, Solana and BNB Chain. The Tempo deployment has been described as the fund’s tenth blockchain integration, although Securitize’s latest primary announcement did not publish a complete network count or updated chain roster. RWA.xyz’s public asset table listed eight unique networks before reflecting the new Tempo deployment.
The multichain strategy gives qualified investors more flexibility over where they hold and transfer their fund shares. It may also help applications integrate BUIDL without requiring users to move their capital back to Ethereum. Expansion across additional blockchains increases technical distribution rather than geographic availability, because participation remains governed by investor-qualification and compliance requirements.
BUIDL is offered in the United States under a private-placement exemption and is limited to qualified purchasers. Securitize has previously disclosed a $5 million minimum initial investment for direct subscriptions, while the interests are not registered under the Securities Act or listed on a public securities exchange. The Tempo launch therefore does not open BUIDL to unrestricted retail participation.
The fund’s size places it among the largest products in the tokenized Treasury sector. RWA.xyz valued the broader category at approximately $10.93 billion on July 31, meaning BUIDL represented close to one-quarter of tracked tokenized U.S. Treasury and Treasury-focused fund value. That market share can change as investors subscribe, redeem or reallocate assets among competing products.
Tokenization also does not remove conventional investment or technology risks. BUIDL seeks to maintain a stable $1 net asset value, but Securitize warns that the fund may not always achieve that objective and that investors remain exposed to regulatory, operational, cybersecurity and principal-loss risks. Blockchain representation changes how fund ownership can be recorded and transferred, not the fundamental risk profile of the underlying investment.
The Tempo deployment ultimately connects a large tokenized Treasury product with a network focused on stablecoin-based payment activity. Its practical impact will depend on investor allocations, application integrations and whether Tempo protocols build productive uses around the fund shares, rather than on the addition of another supported blockchain alone.
