Гаманець для Wrapped SEI (Universal)

What is Wrapped SEI (Universal) (USEI)?

What you hold with uSEI is a Base-side stand-in for SEI. The Universal protocol issues it as an ERC-20 against SEI kept one to one in custody, and burning the ERC-20 is what releases the underlying coin to whoever is entitled to claim it.

Sei's own chain is an unusual one, with a Cosmos-style account layer and an EVM layer stitched together, and the wrapped token participates in neither. No validator delegation, no Sei governance, no paying for Sei transactions. It is a Base token whose price follows SEI and whose usefulness is the lending markets, pools and swaps available on that network. If you wanted SEI in order to use the Sei blockchain, this is not the form to be holding.

As a position, uSEI tends to be bought and then simply kept, since the wrapping step is something people do once. A key that is used rarely is exactly the kind of key that gets lost, and Tangem handles that by creating it inside the card's chip and never exporting it; a duplicate card, kept apart from the first, reproduces the same wallet if anything happens to it, and whether you also want a written seed phrase is left to you. A holding you barely touch deserves storage you barely have to touch either.
