What is cToken?

A Compound v2 receipt token whose exchange rate against the supplied asset increases as lending interest accrues.

Why it matters on your return

Unlike a rebasing token, a cToken's count stays fixed while its redemption value rises. The interest is still income; the question is when. The common position recognizes it at redemption, when it becomes accessible, and treats the cToken as a deposit receipt rather than a separate asset.

Example

You supply 10 ETH to Compound and receive cETH. A year later you redeem the cETH for 10.3 ETH. The 0.3 ETH is interest income at that day's value.

Is interest on a cToken taxed as it accrues or when I redeem?

Unsettled. Because the interest is not accessible until redemption, the common position recognizes it at redemption. We document the position and apply it consistently.
