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
Not provided

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.

Reference prices

Loading
Reference information only. Underlying references (such as XAU / USD) price the reference asset, not the token. No execution venue is configured, so no executable quote, fee, expected output or quote expiry is shown.

Integration capabilities

  • Portfolio balance readRead-only
  • Shield / unshieldNot configured
  • Sealed batch ordersNot configured
  • Eligibility proofNot configured

The issuer quote is null outside US equity market hours, so valuations show as unavailable on weekends.

Transactional integrations are gated by configuration; see integration status.

Verification

Method
Issuer public API (api.xstocks.fi/api/v2/public/assets/{symbol}) matched against on-chain name(), symbol() and decimals(); product characteristics from docs.backed.fi.
