Wrapped CORE wallet

What is Wrapped CORE (WCORE)?

Core runs an EVM environment where CORE is the native coin, and WCORE is that coin held inside a wrapper contract and represented as a standard token. The exchange is mechanical and symmetric: deposit CORE, receive the same number of WCORE; burn WCORE, get the CORE back. Nothing about the underlying asset changes, only the interface through which contracts can touch it.

Why bother? Because a router or a liquidity pool needs to pull a balance from your address after you approve it, and native coins have no approve step. Wrapping gives CORE the same shape as every other token on the chain, which is why WCORE turns up as one side of so many pairs.

For a holder, the thing to internalise is the split between the two balances. Gas on Core is charged in native CORE, never in the wrapped form, so a wallet that wrapped its entire holding has no way to pay for the transaction that would unwrap it. The same applies to any approval or swap you sign afterwards.

Tangem handles this by holding the native coin and the token side by side in one wallet, with the card signing each action by a tap against the phone - no cable, no charging, and the gas balance is right there when the wrapper contract asks for it.
