Available for Compound V3.</td></tr><tr><td>getclaimedrewards</td><td>Read</td><td>Get the rewards claimed by the specified account on the protocol. Available for Compound V3.</td></tr><tr><td>getmaxamounts</td><td>Read</td><td>Get the max withdrawable amount and the max borrowable amount of the base token for a given asset in the protocol for the specified account.
