SanDisk’s return to Nasdaq created a high-priced reference share. BTECH later wrapped its economics in a transferable certificate. The decisive record, custody and redemption path, however, still run through named institutions and an approved prospectus.
SanDisk completed its separation from Western Digital and began trading as SNDK on 24 February 2025. BTECH did not yet exist: the prospectus says the ADGM company was incorporated on 17 April 2026. That sequence matters because SNDKB did not finance or govern SanDisk. It was built later to redistribute exposure to an already-listed share.
The 11 June prospectus calls each token a ledger-based security representing a one-for-one beneficial interest in SNDK. Alpaca holds the shares in BTECH’s segregated account, and BTECH holds its interest on trust for certificate holders. That protection is more specific than a synthetic price feed, yet it stops before corporate ownership: BTECH disclaims the vote, holders are absent from SanDisk’s register, and their limited recourse runs to the custodied share or its net sale proceeds rather than a guaranteed cash value from SanDisk.
The first tranche was expected to contain 545 certificates. It was seeded through a share-borrowing and market-making arrangement, while later minting follows demand. Eligible ADGM subscribers and market makers send instructions through the programme; BTECH decides allocations and BTECH Services executes the mint. A retail wallet can buy or receive SNDKB, but cannot create supply by presenting a share directly to the contract.
Inside the Binance settlement environment, title is recorded on Binance NCCL’s CSD Master Ledger. Delivery-out moves a certificate to BNB Chain, but the CSD continues to treat its ledger as the primary title record and reconciles external addresses against it. If a holding breaches eligibility, sanctions or transfer rules, the token may still appear onchain while the CSD withholds recognition and BTECH Services freezes it at contract level.
A verified holder submits a redemption through Nest Trading on Binance; Alpaca then moves the corresponding SNDK into the holder’s sub-account within Nest Trading’s omnibus account and the certificate is burned. The prospectus promises neither a deadline nor automatic acceptance. Maintenance, corporate actions, screening or issuer decisions can delay, suspend, reject or cancel the order. SNDKB therefore narrows the distance to a share, but does not erase the legal and operational bridge.
The Western Digital separation completed and SanDisk began Nasdaq trading, creating the share later used as SNDKB’s underlying.
The future certificate issuer was formed in ADGM as a Binance Holdings-owned special-purpose company.
The prospectus records the institutional account agreement under which Alpaca holds SNDK in BTECH’s segregated account.
The legal terms set the trust, CSD, transfer and redemption framework and expected an initial tranche of 545 certificates.
Binance opened the pair at 02:00 UTC+8, turning the approved certificate into a secondary-market product.
ADGM’s disclosure page published BTech Services’ schedule as of 28 August and included SNDKB among the reported bStocks.

SNDKB is the SanDisk certificate in BTECH Holdings Limited’s bStocks programme, not a token issued by SanDisk. Its 11 June 2026 prospectus identifies it as an ADGM ledger-based security on BNB Chain, ISIN AE000A4AVAX4, backed one-for-one by beneficial interests in SNDK shares held at Alpaca in BTECH’s segregated custody account. The contract address is `0x3ee4df61bd4f867e349beae8bfe07bc31b4850fb`. A certificate holder has an economic and beneficial interest through the prospectus trust structure, but is not the registered SanDisk shareholder and receives no SNDK vote.
The product tries to make expensive, market-hours-bound SNDK exposure fractional and transferable around the clock. That portability does not move the corporate share register onto BNB Chain. It adds BTECH, Alpaca, Nest Trading, Binance NCCL’s central securities depository and the Binance market between a holder and SanDisk. The result depends on custody reconciliation, eligibility screening and issuer-operated smart-contract controls. A token can remain visible at an external address while the CSD refuses to recognise the holding and the issuer freezes its transfers or economic benefits.
Only eligible ADGM subscribers and institutional market makers can request new certificates; BTECH may accept or reject allocations and mints only after corresponding SNDK exposure enters its Alpaca account. Eligible secondary investors trade certificates through Binance and may request delivery to BNB Chain, but Binance NCCL’s off-chain CSD Master Ledger remains the primary title record and is reconciled with external wallets. Redemption is routed through Nest Trading on Binance: after compliance checks, Alpaca moves the corresponding share to the holder’s sub-account within Nest Trading’s omnibus account and the token is burned. The prospectus gives no processing deadline and permits rejection, cancellation or suspension. Dividends are reinvested after 30% US withholding and reflected through a multiplier, while BTECH Services can mint, burn, freeze, pause, rescind, cancel, upgrade or migrate certificates on BTECH’s instruction.
No. The prospectus gives a verified holder a beneficial interest in SNDK held through BTECH’s trust and custody arrangement, which is stronger than a price-only promise. Legal title and the shareholder-register position remain elsewhere: the holder cannot vote SNDK shares, has no direct claim against SanDisk and becomes a registered shareholder only after a successful conversion into the broker-held equity position; the registration form then follows the brokerage and custody arrangement.
New certificates are issued to eligible ADGM subscribers or institutional market makers, at BTECH’s discretion. A verified eligible secondary investor can submit a redemption order only through Nest Trading on Binance. External possession alone does not create an anonymous mint or redemption path.
The prospectus requires one-for-one beneficial exposure in BTECH’s segregated Alpaca account, and bStocks says it reconciles custody against outstanding supply. Its public proof is periodic and can lag settlement, pending trades or operating adjustments, so a displayed proof is evidence for its stated time rather than a live guarantee for every block.
BTECH reinvests cash dividends into additional SNDK after the prospectus’s 30% US withholding tax and changes an on-chain multiplier. Splits use the same mechanism. Holders do not receive SanDisk cash dividends directly, and their effective balance can change without a matching transfer of raw token units.
A permitted holder can request delivery to a BNB Chain address and may make peer-to-peer transfers, but the security’s restrictions travel with it. The CSD monitors and reconciles external positions; an ineligible or sanctioned address can be denied recognition, frozen, blacklisted or prevented from receiving economic benefits.
Under the prospectus, BTECH Services operates the contract on the issuer’s instruction. Those powers cover minting, burning, freezing, pausing, rescinding, cancelling and upgrading; the issuer may also migrate certificates to another blockchain or system. Self-custody therefore changes where the token sits, not who administers the security.
