BlackRock

BlackRock is the world's largest asset manager. On Solana, it runs cash funds whose shares live as tokens in approved wallets. The main one is BUIDL, the BlackRock USD Institutional Digital Liquidity Fund. It came to Solana in March 2025. By October 2026, Solana held more BUIDL than any other chain, per RWA.xyz. A second fund, BRSRV, launched in August 2026 to hold reserves for stablecoin issuers.

Both funds hold cash and short-term U.S. government debt. They are for big institutions only, and you need millions of dollars to get in. BlackRock has no Solana token. As of October 2026, it also has no spot Solana ETF.

What is BlackRock BUIDL on Solana?

BUIDL is a tokenized money market fund. It launched on Ethereum in March 2024 with Securitize, a registered transfer agent that runs the fund's on-chain share register. Each token is one fund share. The fund aims to hold a steady $1.00 value per share, and it pays its Treasury yield to holders as new tokens.

BUIDL added Aptos, Arbitrum, Avalanche, OP Mainnet and Polygon in November 2024. It reached Solana on March 25, 2025, according to Wormhole, which handles BUIDL's cross-chain transfers. The Solana share class carries a 20 basis point management fee. Its token address is GyWgeqpy5GueU2YbkE8xqUeVEokCMMCEeUrfbtMw6phr.

As of October 26, 2026, RWA.xyz lists BUIDL on nine networks, with Solana the largest by value. The fund had about 101 holders, which shows how few, and how large, its investors are.

How BUIDL works: Securitize, whitelisted wallets and daily yield

An investor first passes Securitize's identity and eligibility checks. Securitize then adds their wallet to an allowlist. The investor pays in, and Securitize mints BUIDL to that wallet. Holders can send BUIDL to other approved wallets at any hour, but a transfer to an unapproved address fails.

Yield builds up daily and is paid as freshly minted tokens. Redemptions go back through Securitize. RWA.xyz lists a $250,000 minimum redemption, paid in USDC.

On Solana, much of the supply sits with qualified custodians rather than in self-custody wallets. When BUIDL on Solana reached $525.4 million in the first quarter of 2026, Anchorage Digital held about 81% of it, per a CoinMarketCap report. Anchorage had just added custody support for the token.

BRSRV (RSVXX): BlackRock's stablecoin reserve fund on Solana

BRSRV is the BlackRock Daily Reinvestment Stablecoin Reserve Vehicle, fund ticker RSVXX. BlackRock filed for it with the SEC on July 31, 2026. The filing says the fund records share ownership on public blockchains including Solana, Ethereum and Tempo, per IG's reading of the filing. It launched on August 3, 2026, with Securitize again as transfer agent.

The fund is built for stablecoin issuers. It is designed to count as an eligible reserve asset under the GENIUS Act, the 2025 U.S. law for payment stablecoins. It holds only cash, short-term Treasuries and overnight repos backed by Treasuries, with no crypto exposure. It reinvests dividends daily and has a $3 million minimum initial investment, per Decrypt.

"Cash remains a foundational building block for investors, corporations, and financial institutions," said Jon Steel, who heads product and platform for BlackRock's cash management business, at launch.

BlackRock already runs reserves for one big stablecoin off-chain. The Circle Reserve Fund (USDXX), which holds USDC reserves for Circle USDC$1.000-0.1%, had about $62.8 billion in net assets at August 31, 2026. BRSRV offers other issuers a similar fund with on-chain shares. Our news covered the launch: BlackRock launches BRSRV and BSTBL tokenized money market funds.

Is BSTBL on Solana?

Not according to BlackRock. It launched BSTBL, a token share class of its Select Treasury Based Liquidity Fund, on the same day as BRSRV. Some reports, ours among them, called both funds Solana launches. But BlackRock's press release says the BSTBL share class is issued on Ethereum, with BNY as transfer agent and tokenization provider, as The Block also reported. Of the two August funds, only BRSRV names Solana.

Does BlackRock have a Solana ETF?

No. As of October 2026, BlackRock has not filed for a U.S. spot Solana ETF. It said in August 2025 that it had no immediate plans for one, Helius reported. In October 2026 it filed a third Bitcoin product instead, and analysts still noted the absence of any SOL fund.

Spot Solana ETFs do exist from other issuers, including Bitwise (BSOL), Grayscale (GSOL), VanEck (VSOL) and Canary Marinade (SOLC). Investors who want SOL exposure through an ETF have to use one of those, or hold and stake SOL directly.

Does BlackRock own Solana? BlackRock stock on Solana

Searches for "BlackRock Solana price" or "BlackRock Solana coin" often mix up three things:

• BlackRock's own Solana activity is issuing BUIDL and BRSRV shares on the network. It is not a SOL fund, and there is no BlackRock token.
• Tokenized BlackRock stock (BLK) is a separate, third-party product. Backpack Securities listed it on Solana in October 2026. It trades around the clock on DEXs and is designed to redeem 1:1 for BLK shares. BlackRock does not issue it. See our coverage: Backpack Securities lists tokenized BlackRock stock on Solana.
• Tokens with "BlackRock" or "BUIDL" in the name on DEXs are not BlackRock funds unless the mint matches the issuer's published address. Real BUIDL cannot trade on an open DEX, because transfers only work between approved wallets.

Who can invest in BlackRock's Solana funds?

These funds suit institutions that hold stablecoins or cash on-chain and want Treasury yield without leaving the chain. Every holder must first pass Securitize's checks. BRSRV is aimed at stablecoin issuers that need GENIUS Act-eligible reserves.

The constraint is size and status. BUIDL needs $5 million to start and is limited to qualified purchasers, per RWA.xyz. BRSRV needs $3 million. Retail investors cannot buy either one. For them, the nearest options are holding SOL, staking it, or buying tokenized products open to individuals.

Is BlackRock BUIDL safe? The risks

The assets are conservative: cash, Treasury bills and repo, run by the largest manager in the industry. The bigger risks sit in the token layer and the access rules.

• Issuer control. BUIDL is permissioned by design. Securitize keeps the allowlist and can freeze, redeem or reissue holdings where rules require it. Holders do not have the censorship resistance of a normal Solana token.
• Access and exit. Only approved wallets can hold or receive the token. Redemptions run through Securitize with a $250,000 minimum, so you cannot just sell on a DEX.
• Bridge and contract risk. Cross-chain transfers use Wormhole W$0.011-4.6%. A fault in the bridge or the token contracts would hit the on-chain shares, even if the fund's assets were untouched. We found no public smart contract audit for the Solana token.
• Concentration. BUIDL has about 100 holders in total, and one custodian held most of the Solana supply in early 2026. One large holder moving chains can shift Solana's balance by hundreds of millions of dollars.
• Rate risk. Yield tracks short-term U.S. rates. When the Fed cuts, BUIDL's yield falls with it.

BUIDL alternatives on Solana

BUIDL is not the biggest tokenized Treasury fund overall. By October 6, 2026, Circle's USYC and Ondo USDY$1.15-0.1%'s USDY were both larger by total value, per RWA.xyz data. On Solana, Ondo's USDY, Franklin Templeton and WisdomTree also offer tokenized Treasury products. Check each one's eligibility rules and minimums, which differ by issuer. Our report on Solana leading tokenized Treasury inflows compares the field.

The trade-off is plain. BUIDL and BRSRV carry BlackRock's name and a regulated fund wrapper, which matters to compliance teams. The cost is high minimums and a closed holder list.
