The press release reads like a victory lap: Backpack, the Solana-native exchange and wallet, now offers 24/7 trading of US equities, including SpaceX shares. But read between the lines. There is no mention of settlement layers, oracle feeds, or audit trails. For a protocol that claims to bridge TradFi and DeFi, the absence of technical disclosure is not a detail—it’s a signal.
If it isn’t formally verified, it’s just hope. And hope is not a cryptographic primitive.
Context: The Product and Its Missing Blueprints Backpack launched in 2022 with a focus on self-custody wallets and a centralized exchange built on Solana. Its new “24/7 US Stock Market” allows users to trade tokenized representations of companies like SpaceX—which has not yet held an IPO. The market operates round-the-clock, a clear departure from traditional exchanges that follow T+1 settlement and market hours.
The promise is simple: buy and sell fractional ownership of hard-to-access private equities, 24/7, via a crypto interface. The execution is opaque. Backpack has not disclosed whether these tokens are synthetic derivatives (price feeds with no underlying custody) or actual security tokens backed by a regulated broker-dealer. This distinction is not academic—it determines whether the product is a legitimate financial instrument or an unregistered securities offering.
Based on my experience auditing Solidity implementations for the Zeppelin library in 2017, I learned that the first thing any security-conscious architect does is demand the threat model. Here, there is none. The article from Crypto Briefing repeats the announcement verbatim. No technical details. No formal verification reports. No audit. That silence is my starting point.
Core: Teardown of the Likely Technical Stack Let me reconstruct what Backpack probably did. Given the absence of on-chain settlement details, the most plausible architecture is a hybrid model: Backpack’s centralized order book matches trades internally, while a smart contract—likely on Solana—issues a token representing the stock. The price is fed by a centralized oracle (e.g., a Bloomberg terminal API) or a decentralized one like Pyth Network, which Backpack already integrates.
This is not innovation. It is a repackaging of the FTX equity token model that collapsed in 2022. The key difference is that FTX used a regulated German custodian (CM-Equity) to hold the underlying shares and issue tokens under prospectus exemptions. Backpack has not disclosed any such arrangement.
I stress-tested a similar architecture in 2021 during my teardown of the ERC-721 vs ERC-1155 standards. The core inefficiency remains: every trade on a centralized book requires trust in the operator. The 24/7 claim is trivial when the matching engine is a central server. The real challenge is settlement finality, which Backpack does not address.
Code is law, but law is interpretive. In this case, the “code” is just a ledger entry. If Backpack’s servers go down or are seized, the tokens are worthless. Institutional-grade security requires multi-sig cold storage and SOC2 compliance. Backpack has not published its custody architecture for this market.
Contrarian: The Real Innovation Is Regulatory Arbitrage, Not Technology The contrarian angle is not about 24/7 liquidity—that’s a solved problem. It’s about the specific choice of SpaceX. Why SpaceX? Because it is the most valuable private company in the world, with a massive retail appetite for pre-IPO exposure. By tokenizing it, Backpack offers something Robinhood and Schwab cannot: unregistered, unregulated access to a private company’s equity.
This is a regulatory landmine. The Howey Test clearly applies: users invest money in a common enterprise (Backpack’s platform) expecting profits from the efforts of others (SpaceX’s management). The SEC has already taken action against similar products, such as the Uniswap governance token and various ICOs. In 2024, the agency fined a platform for offering tokenized shares of Apple without registration.
Backpack likely restricts US users, but the announcement does not state this. If US residents can trade—or if the token is accessible via VPN—the platform violates US securities laws. The risk is not hypothetical; it is structural. During the Terra collapse in 2022, I spent 72 hours analyzing the seigniorage model and concluded that the positive feedback loop was fatal. Here, the feedback loop is regulatory: either SEC enforcement shuts the market down, or liquidity fails to materialize, and the market dies from neglect.
Takeaway: A Fragile Equilibrium Backpack’s 24/7 stock market is a clever product in a regulatory vacuum. It will survive only as long as the SEC chooses to ignore it—or until a competitor with a proper license captures the liquidity. The standard is obsolete before the mint finishes.
If you are considering using this market, ask for the legal prospectus, the audited smart contract, and the name of the registered broker-dealer. If they cannot provide these, treat the tokens as synthetic derivatives with counterparty risk. The price may reflect SpaceX’s valuation, but the settlement depends entirely on Backpack’s solvency.
