Ethena Labs. Ethena Labs.
Ethena publishes USDe as a token backed by a delta-neutral position: collateral hedged with a short derivatives position, not by cash in a bank account described in this note.
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 synthetic dollar is not a deposit. If the hedge, the exchange, or the custody fails, the token's claim is whatever the docs say survives, not par by slogan.
Claim 02 · Paper model
The proposal
Ethena publishes USDe as a token backed by a delta-neutral position: collateral hedged with a short derivatives position, not by cash in a bank account described in this note.
Claim 03 · Paper model
The mechanism
The hedge is the design. Long collateral plus a short perpetual is not the same object as a treasury bill or a bank deposit.
Claim 04 · Paper model
The bound
No yield, no reserve total, and no peg measurement 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 synthetic dollar is not a deposit. If the hedge, the exchange, or the custody fails, the token's claim is whatever the docs say survives, not par by slogan.
Model
What has to hold
You are reading Ethena's own protocol docs. Commentary that adds a yield figure is a different text.
Falsifier
What would retire it
What assets does the document say sit behind the token?

What the study says
The hedge is the design. Long collateral plus a short perpetual is not the same object as a treasury bill or a bank deposit.
Model
What has to hold
No price, supply, yield, or adoption figure is added by this desk.
Falsifier
What would retire it
Where is the hedge held, and who can refuse a withdrawal of collateral?

03 Sequence
One action, as an operating tape
- 01The hedge is the design. Long collateral plus a short perpetual is not the same object as a treasury bill or a bank deposit.
- 02Funding on the short can be a receipt or a cost. This note does not state which, and it does not state a rate.
- 03Custody of the collateral and the venue of the hedge are trust assumptions. They have to be named in the docs you rely on.
04 Load-bearing
The argument, and where a pitch drops it
What the name has to mean
The cut
Ethena publishes USDe as a token backed by a delta-neutral position: collateral hedged with a short derivatives position, not by cash in a bank account described in this note.
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
This is Ethena Labs the protocol publisher. It is not any other company with a similar name.
What actually moves
The cut
Funding on the short can be a receipt or a cost. This note does not state which, and it does not state a rate.
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 a later deployment may change
The cut
Custody of the collateral and the venue of the hedge are trust assumptions. They have to be named in the docs you rely on.
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
A secondary-market price near one dollar is not a redemption guarantee.
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.

The paper, in the order a builder needs
The problem it names
A synthetic dollar is not a deposit. If the hedge, the exchange, or the custody fails, the token's claim is whatever the docs say survives, not par by slogan.

09 Lexicon
Terms, opened into the record
- Delta-neutral position
- Collateral hedged so that a price move in the asset is offset by a derivative. The hedge can fail.
- Synthetic dollar
- A token designed to track a dollar claim. The design is not a bank deposit.
