What is Principal token?

A yield-tokenization asset that represents the right to redeem principal at maturity under a protocol's terms.

Why it matters on your return

Buying a PT at a discount and redeeming at par produces gain at maturity, similar in economics to a zero-coupon bond, though crypto is property rather than a debt instrument. The common position treats the discount as capital gain on redemption; a minority view analogizes to original issue discount.

Example

You buy PT-stETH for 0.95 ETH that redeems for 1 ETH at maturity in ten months. On redemption the 0.05 ETH difference is gain; because the PT is property, the common position treats it as capital gain, short-term here.

Is the discount on a principal token interest or capital gain?

Unsettled. The common position is capital gain on redemption because the token is property; some practitioners analogize to original issue discount and accrue it. We document the position.
