cAAVE wallet

What is cAAVE (CAAVE)?

cAAVE is not AAVE. It is the receipt token issued by Compound's lending protocol when AAVE is supplied to its market, and confusing the two is the single biggest trip-up with this asset. Holding cAAVE means holding a claim on AAVE inside the protocol, redeemable through it; holding AAVE means holding the underlying token.

How the balance behaves

The number of cAAVE in your wallet does not change on its own. What changes is the exchange rate between cAAVE and AAVE, which moves upward as borrowers in that market pay interest. So the same token count corresponds to a slowly growing amount of redeemable AAVE, with no rebase and no action from you. Because cTokens are denominated in small units, balances often read in the thousands even for a modest position; that is the unit, not the size of the claim.

One more consequence: AAVE supplied to Compound is not sitting in your wallet, so it cannot be used for votes in Aave's own governance while it is lent out. Transferring cAAVE to someone else transfers the whole claim, redemption right included.

Since the claim grows through the exchange rate rather than through any transaction you sign, there is nothing to maintain. Tangem simply reads what the chain reports for the token, and the card can stay in a drawer for as long as the position stands, which is about as little attention as a wallet for this token needs to demand.
