SanDisk Joins Solana's Tokenized Equity Roster as Sunrise and Backpack Launch $SNDK

Twelve days after Sunrise and Backpack put SpaceX on Solana, and two days after they did the same for Micron, a third tokenized US equity is live on the chain. SanDisk ($SNDK) began trading on Solana at 13:36 UTC on June 24, backed 1:1 by real shares held at Backpack Securities, the regulated US broker behind the earlier issuances.

The official Sunrise account confirmed the launch at 13:36 UTC, calling SanDisk "a global semiconductor leader and a breakout name in AI-memory." The official @solana account followed within a minute, labeling the announcement "BREAKING" and crediting Backpack Securities as issuer.

What SNDK Is and How It Works

SNDK tokens are redeemable 1:1 for actual SanDisk shares. Holders can convert them back into traditional brokerage accounts through standard settlement infrastructure, making the token a genuine custody wrapper rather than a derivative. Sunrise, an asset gateway built on Wormhole, handles the on-chain issuance and distribution. Backpack Securities, a regulated US broker, holds the underlying shares.

Trading is live 24/7 on Jupiter JUP$0.209+3.5% and Raydium RAY$0.572-4.5%, plus on Backpack Exchange itself, where up to 10x margin is available. HumidiFi is providing market making with tight spreads. Traditional equity markets run 6.5 hours a day, five days a week; SNDK trades the other 130-plus hours too.

SanDisk was spun off from Western Digital in February 2025 and now trades independently on Nasdaq. The company manufactures NAND flash memory and SSDs used across data centers, AI infrastructure, and consumer electronics, which Sunrise cited as the basis for selecting it as the third listed asset.

The Third Equity in Twelve Days

As we covered when SPCX launched on June 12, Backpack and Sunrise debuted that token the same day SpaceX listed on Nasdaq, a first for any tokenized equity. Micron ($MU) followed on June 22, timed ahead of Micron's fiscal Q3 earnings release. SanDisk is the third in the series, arriving as tokenized equities claim an all-time high share of daily Solana DEX spot volume, making them the second-largest trading category on the chain and surpassing memecoins for the first time.

The pace suggests Sunrise and Backpack are treating stock selection as a deliberate editorial program. The first two picks had clear catalysts: SpaceX's simultaneous Nasdaq IPO, then Micron's earnings window. SanDisk adds a third angle, positioning as a storage and AI-memory name tied to the data center buildout cycle.

Solana Foundation Adds a $25K Trading Campaign

Alongside the launch, the Solana Foundation announced a $25,000 prize pool through its Frontier Traders program, directed at trading SNDK on-chain. The campaign runs through Torque (Torque Protocol), which distributes rewards for qualifying trading activity. Frontier Traders is the Foundation's institutional-tier trading initiative requiring $500M in 30-day volume to participate; it previously ran a campaign around SPCX at launch, and the SNDK edition follows the same template.

The Foundation's involvement reflects the same coordinated playbook used for SPCX: issue the token, seed DeFi venue integrations on day one, and layer in a structured trading campaign to build liquidity from multiple directions at once.

How SPCX Volume Set the Benchmark for SNDK

The Sunrise-Backpack pipeline is not the only route to tokenized equities on Solana, but it has developed the clearest structure for share-backed issuance. SPCX surpassed $100 million in 24-hour trading volume within days of launch and drove 91.7% of all tokenized SpaceX volume across chains, helping Solana set a $1.04 billion weekly tokenized equity volume record on June 20.

The 1:1 share backing and ACATS-compatible redemption pathway have been the consistent differentiator in that market share. Competing products built on SPV structures or synthetic exposure have attracted less capital by comparison.

Whether SNDK replicates SPCX's volume trajectory depends partly on demand for SanDisk specifically. It is a semiconductor name with a clear AI-infrastructure narrative, but it lacks the brand recognition of SpaceX and carries the overhang of being a recent corporate spin-off. The 24/7 structure does give holders a continuous settlement window through earnings releases, analyst actions, or macro developments that move the stock after traditional market hours close.
