Principal Tokens (PT) represent the principal portion of yield-bearing assets. At maturity, PT can be redeemed at a 1:1 ratio for the underlying asset. These are the principal assets deployed in the underlying protocol, such as Polkadot's DOT or Moonbeam's GLMR.
The process of converting matured PT into the underlying asset involves two steps (using PT-vDOT as an example):
Step 1: At maturity, 1 PT-vDOT can be converted into vDOT worth 1 DOT (the amount of vDOT convertible may be less than 1, depending on the yield-bearing asset's mechanism).
Step 2: Directly swap vDOT for DOT on Zenlink Eden (Zenlink Mega Aggregator will calculate the best trading route and execute the swap for you).
Since the total value of its yield component is separated, PT can be acquired at a discount relative to its underlying asset. Assuming no swaps occur, the value of PT will gradually approach and eventually match the value of the accounting asset at maturity when the redemption feature is enabled.
This appreciation forms the basis for its fixed RIO.
Generally, yield-bearing assets can be categorized into:
Rebasing assets - Tokens that increase in quantity over time
Examples: stETH, stDOT
Reward-bearing assets - Tokens that appreciate over time
Examples: vDOT, wstETH
For yield-bearing assets, it is important to note that PT can be redeemed at a 1:1 ratio for the underlying asset, not the yield-bearing asset. For example, the value of Bifrost's vDOT appreciates relative to DOT over time as staking rewards accumulate. Holding 1 PT-vDOT will allow you to redeem vDOT worth 1 DOT at maturity, not 1 vDOT, which has a higher value.
