Rebasing token: balanceOf already reflects the corporate-action multiplier, so one token tracks one share. 18 decimals.
Terms, as documented by the issuer
- Holder rights
- Per the xStocks documentation, each xStock represents the economic value of the underlying share, is backed 1:1 by that share held in segregated custody under a three-party account control agreement with an independent security agent, and reflects dividends and splits through an on-chain rebasing mechanism. The documentation we checked does not describe shareholder rights such as voting; treat them as not provided.
- Redemption
- Issuance and redemption through the issuer operate 24/5 for onboarded users (issuer documentation); otherwise tokens trade on secondary venues.
- Eligibility
- Not intended for distribution in the United States, to US persons or in other prohibited jurisdictions; the issuer's legal documentation lists restricted countries.
- Transfer restrictions
- Described by the issuer as permissionless with no technical transfer restrictions. On EVM networks the token rebases; the issuer provides ERC-4626 wrappers (wrapperAddressV2 in its public API) for protocols that need a non-rebasing balance.
- Fees

Nothing here is inferred from the token name. "Not provided" means the issuer pages we checked did not state it; it does not mean the right or restriction is absent.
