Wrapped bMSTR wallet

What is Wrapped bMSTR (WBMSTR)?

WBMSTR comes out of Backed's line of tokenized securities: tokens that track a listed instrument and are collateralized by the real thing held with a custodian. This one tracks MSTR stock. It is a financial product issued under an EU prospectus, and it is not offered to US persons, so the primary market side of it is closed to a good part of the world even though the token itself moves freely between addresses onchain.

The wrapped part is worth understanding. A token tracking a share has to deal with corporate actions, and adjusting a holder's token count is one way to do it, which contracts and integrations handle badly. The wrapped form fixes the token count in your wallet and carries the adjustment in the ratio between the token and the underlying instead. Your balance stays a round number; what it represents shifts.

This also means minting and redeeming happen with the issuer under onboarding conditions, not on the open market. For most holders the token is something bought and then held, sometimes across a corporate action or two, at the same address the whole time.

A position meant to sit still for years needs a key that survives just as long. Tangem generates it inside the card's secure element and never exports it, and a second card from the same set reproduces the same addresses if the first one disappears, with a seed phrase available only if you specifically want a written copy. Custody you can leave untouched for a year is the real requirement for an asset like this, and a card in a drawer meets it.
