What is c0x (CZRX)?
The asset underneath cZRX is ZRX, the token of the 0x trading protocol. Supplying ZRX to Compound v2 produces cZRX, and from that moment the wallet holds a claim on the lending market rather than ZRX itself.
A cZRX balance cannot be used where ZRX is used. It is not accepted by 0x contracts, and has to be redeemed against the cZRX contract first; the token quantity stays flat while the contract's exchange rate against ZRX is what shifts. Decimals differ too, 8 for the receipt against 18 for ZRX, so the displayed figure looks nothing like the deposit.
Redeeming is where people get stuck: it is an Ethereum transaction, and it is paid in ETH. A wallet that contains cZRX and nothing else cannot unwind the position at all. In Tangem the ETH for that call sits in the same wallet as the receipt token, and signing is a tap of the card against the phone, with no cable and no battery to worry about for a transaction that may be years overdue. Being able to close an old position in one sitting is the reason to keep both here together.
