Wrapped SOMI wallet

What is Wrapped SOMI (WSOMI)?

SOMI is the native coin of Somnia, an EVM-compatible layer 1 aimed at games and consumer applications that need a lot of cheap transactions. On its home chain it pays for gas the way ETH does on Ethereum, which means it is not an ERC-20 there. WSOMI is the wrapped form that fills that gap: a standard token contract holding the native coin, so it can be bridged, listed and passed to contracts that only understand ERC-20s.

What a holder actually has, then, depends on which chain the balance sits on. A WSOMI balance on Ethereum, BNB Smart Chain or Base is a bridged representation - it is portable and easy to trade, but it does not pay gas on Somnia and does not take part in anything happening on the Somnia chain itself. Getting back to the usable native coin means crossing the bridge and unwrapping. Fees for moving the wrapped token follow the host chain: ether on Ethereum and Base, BNB on BNB Smart Chain.

Supported networks in Tangem (3): Base, Ethereum, BNB Smart Chain.

Since the same token turns up under the same address on three different chains, Tangem keeps the three balances apart in the app and states the outgoing network on the signing screen, so you read it back before the card is tapped. Holding a multi-deployment token on hardware where that check is part of the signing step, rather than an afterthought, is the sensible arrangement here.
