Solana Explainer: How Backpack Securities Brings Real Stocks Onchain

Solana's latest explainer breaks down how real stocks move onchain through Backpack Securities: purchased through the U.S. brokerage system, withdrawn onto Solana as tokens, and deposited back at any time. Two forms, one asset.

‍Key Facts

• Real stocks purchased through the U.S. brokerage system can be withdrawn onto Solana as tokens through Backpack Securities.
• Investors can move eligible stocks between the U.S. brokerage system and Solana.
• Tokenized stocks on Solana surpassed $4.9 billion in trading volume in the first half of 2026.
• Backpack's tokenized SpaceX ($SPCX) launched on Solana the same day SpaceX listed on Nasdaq.
• More than $470 million of $SPCX was traded during its first week.
• Stocks withdrawn onto Solana remain connected to the underlying security entitlement established through the brokerage system.
• Tokenized stocks can be transferred, traded, and used across the Solana ecosystem.
• Investors can deposit tokenized stocks back into Backpack Securities and redeem them 1:1 for the corresponding security entitlement.

Why Did Backpack's Tokenized SpaceX Launch Attract Attention?

‍Tokenized stocks on Solana surpassed $4.9 billion in trading volume in the first half of 2026. Then came SpaceX. Backpack's tokenized SpaceX ($SPCX) launched on Solana the same day SpaceX listed on Nasdaq. Within a week, it became the highest-volume tokenized version of SpaceX in the world, with more than $470 million traded.Why did the launch attract so much attention? The answer comes down to ownership.

What Happens When You Buy a Stock Through Backpack Securities?

‍When you buy a stock through a traditional broker, ownership is recorded within a regulated legal system. That ownership carries rights such as dividends, voting rights, and corporate actions.

Historically, that ownership has remained within the brokerage system. With Backpack Securities, an investor purchases a real security through the U.S. brokerage system, with ownership established under securities law. That same stock can then be withdrawn onto Solana as a token.

What Happens When a Stock Moves Onchain?

‍Once onchain, the token is transferable, tradable, and compatible with applications across the Solana ecosystem, 24/7.

It can also move back at any time. When deposited into Backpack Securities, the token redeems one-for-one for the corresponding underlying security entitlement.

There is no disconnect between the two forms. The same asset can move between the U.S. brokerage system and Solana because both are linked through the underlying ownership.

That is why, when SpaceX listed, investors could access the asset through both traditional brokerage infrastructure and onchain markets.

How Is This Similar to Stablecoins?

‍A useful comparison is stablecoins. Stablecoins did not replace the dollar. They enabled dollars to move on blockchain networks while remaining redeemable for the underlying asset.

Backpack Securities applies a similar concept to equities by allowing stocks purchased through the U.S. brokerage system to move onchain while maintaining a connection to the underlying security entitlement.

‍What Does This Mean for Traditional and Onchain Finance?

‍The goal is not to replace traditional finance with crypto, or crypto with traditional finance. Instead, the model enables assets to move between traditional brokerage infrastructure and blockchain networks. By connecting both environments, investors can access the same underlying asset in either form while maintaining a link to the underlying ownership.
