The Register · tokenized SPCX
What a tokenized SPCX holder owns
11 tokens issued by 11 programs track Space Exploration Technologies Corp. Class A. They share a ticker and little else. 11 are on file; each row below links the file with the issuer’s own words.
What the holder owns
4 versions on file give the holder a claim on a real share that a custodian holds, not the share in the holder’s own name, and no vote: bStocks, Backpack Securities stock tokens, Coinbase Tokenized Stock, Anchored aStocks. 7 versions are notes or swaps that pay like the share and carry no rights in it: xStocks, PREOPAI and PRESPCX, Robinhood Stock Tokens, Ondo Global Markets, rTokens, Dinari dShares, Tessera T-Tokens. None gives the holder the Space Exploration Technologies Corp. Class A share itself, and none carries SIPC protection in the wallet.
Who may hold it
No version on file is offered to US persons.
Who can freeze it
In 5 of the 11 programs with a readable contract, one private key can freeze, pause, or claw back holders’ tokens, or grant that power: xStocks, Robinhood Stock Tokens, Dinari dShares, Coinbase Tokenized Stock, Tessera T-Tokens.
Where it is used
Coinbase Tokenized Stock’s SPCXc: Aave v4 on Base has taken AAPLc, AMZNc, GOOGLc, METAc, MSFTc, NVDAc, and TSLAc as collateral for USDC loans since 2026-09-25. A client who supplies USDC there lends against these certificates; a client who borrows against them can be liquidated into the Base bid while the stock market is closed. Read the Aave v4 memo.

Market cap is CoinGecko’s figure on 2026-09-24, for the token itself, not the share it tracks. “Freeze key held by” names the weakest key that can freeze, pause, or claw back a holder, or grant that power, read from the chain.
