Pendle: splitting a yield-bearing token into principal and yield
Pendle. Pendle.
Pendle's design wraps a yield-bearing token and splits a maturity into a principal claim and a yield claim that can be traded separately.
A reading of the project's public design document. Not a copy, not a benchmark, and not an offer.

01 Claim ledger
What the paper is allowed to say
Each row is a sentence already in the study. The status is the same on every row: a model claim, not a live measurement.
Claim 01 · Paper model
The defect
A yield token is not the yield. It is a claim on whatever the wrapped asset pays until a date. If the wrapped asset pays nothing, the claim pays nothing.
Claim 02 · Paper model
The proposal
Pendle's design wraps a yield-bearing token and splits a maturity into a principal claim and a yield claim that can be traded separately.
Claim 03 · Paper model
The mechanism
Standardised yield, in the docs, is the interface that lets different assets be split. The interface is not the source of the yield.
Claim 04 · Paper model
The bound
No APY is stated here.
02 Three cuts
Observation, model, falsifier
A desk does not stop at the summary. Each claim is cut three ways, using only this study's own assumptions and checks. Nothing here is a new figure.
01 The defect
Observation
What the study says
A yield token is not the yield. It is a claim on whatever the wrapped asset pays until a date. If the wrapped asset pays nothing, the claim pays nothing.
Model
What has to hold
No price, supply, yield, or adoption figure is added by this desk.
Falsifier
What would retire it
What asset is wrapped, and who owes its yield?
02 The proposal
Observation
What the study says
Pendle's design wraps a yield-bearing token and splits a maturity into a principal claim and a yield claim that can be traded separately.
Model
What has to hold
You are reading Pendle's protocol mechanics. A rate shown on a website is not this document.
Falsifier
What would retire it
What does the principal token redeem for at maturity?
03 The mechanism
Observation
What the study says
Standardised yield, in the docs, is the interface that lets different assets be split. The interface is not the source of the yield.
Model
What has to hold
The document is the one at the source URL. A marketing page with the same brand is not this text.
Falsifier
What would retire it
What asset is wrapped, and who owes its yield?
04 The bound
Observation
What the study says
No APY is stated here.
Model
What has to hold
You are reading Pendle's protocol mechanics. A rate shown on a website is not this document.
Falsifier
What would retire it
What asset is wrapped, and who owes its yield?
03 Sequence
One action, as an operating tape
- 01Standardised yield, in the docs, is the interface that lets different assets be split. The interface is not the source of the yield.
- 02The AMM trades the split claims. Its price is a market, not a forecast the protocol guarantees.
- 03At maturity the principal claim is about the underlying, under the rules of that underlying. Pendle does not become the issuer.
04 Load-bearing
The argument, and where a pitch drops it
What the name has to mean
The cut
Pendle's design wraps a yield-bearing token and splits a maturity into a principal claim and a yield claim that can be traded separately.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
A later client, parameter or reward formula is a different object from this paragraph.
What actually moves
The cut
The AMM trades the split claims. Its price is a market, not a forecast the protocol guarantees.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
The wrapped asset's own risk, including a depeg or a freeze, passes through the split.
What a later deployment may change
The cut
At maturity the principal claim is about the underlying, under the rules of that underlying. Pendle does not become the issuer.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
A later client, parameter or reward formula is a different object from this paragraph.

06 Divergence
What happened after the paper
The wrapped asset's own risk, including a depeg or a freeze, passes through the split.
A later client, parameter set, or reward formula is a different object. Cite this paper for the mechanism. Cite a primary release for the network. This desk has not re-run the proof.

08 Anatomy
The paper, in the order a builder needs
The problem it names
A yield token is not the yield. It is a claim on whatever the wrapped asset pays until a date. If the wrapped asset pays nothing, the claim pays nothing.
What the design proposes
- Standardised yield, in the docs, is the interface that lets different assets be split. The interface is not the source of the yield.
- The AMM trades the split claims. Its price is a market, not a forecast the protocol guarantees.
- At maturity the principal claim is about the underlying, under the rules of that underlying. Pendle does not become the issuer.
How the mechanism is specified
- Standardised yield, in the docs, is the interface that lets different assets be split. The interface is not the source of the yield.
- The AMM trades the split claims. Its price is a market, not a forecast the protocol guarantees.
- At maturity the principal claim is about the underlying, under the rules of that underlying. Pendle does not become the issuer.
What this page does not treat as proven
- No APY is stated here.
- A point or incentive programme is not the mechanism and is not cited.
- The wrapped asset's own risk, including a depeg or a freeze, passes through the split.
Why the desk still reads it
Pendle's design wraps a yield-bearing token and splits a maturity into a principal claim and a yield claim that can be traded separately.
09 Lexicon
Terms, opened into the record
- Principal token
- The claim on the underlying at maturity, not on the yield before then.
- Yield token
- The claim on the yield until maturity. It can go to zero if the source pays nothing.
