dYdX v4: an application-specific chain for perpetuals

dYdX v4. dYdX Trading.

dYdX v4 moves the perpetual order book onto its own chain, so matching is no longer a set of Ethereum transactions in a smart contract.

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.

  1. Claim 01 · Paper model

    The defect

    Leaving Ethereum does not, by itself, change the definition of a perpetual. It changes who orders trades and which light client you must trust.

  2. Claim 02 · Paper model

    The proposal

    dYdX v4 moves the perpetual order book onto its own chain, so matching is no longer a set of Ethereum transactions in a smart contract.

  3. Claim 03 · Paper model

    The mechanism

    The chain's consensus finalises orders and trades. The v3 StarkEx deployment is a different design and a different document.

  4. Claim 04 · Paper model

    The bound

    No volume, fee, or funding rate 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.

  1. 01 The defect

    Observation

    What the study says

    Leaving Ethereum does not, by itself, change the definition of a perpetual. It changes who orders trades and which light client you must trust.

    Model

    What has to hold

    You are reading the v4 documentation. The v3 system is a different object.

    Falsifier

    What would retire it

    Which document is in force: v3 StarkEx or the v4 chain?

  2. 02 The proposal

    Observation

    What the study says

    dYdX v4 moves the perpetual order book onto its own chain, so matching is no longer a set of Ethereum transactions in a smart contract.

    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

    Which document is in force: v3 StarkEx or the v4 chain?

  3. 03 The mechanism

    Observation

    What the study says

    The chain's consensus finalises orders and trades. The v3 StarkEx deployment is a different design and a different document.

    Model

    What has to hold

    You are reading the v4 documentation. The v3 system is a different object.

    Falsifier

    What would retire it

    Which document is in force: v3 StarkEx or the v4 chain?

  4. 04 The bound

    Observation

    What the study says

    No volume, fee, or funding rate is stated here.

    Model

    What has to hold

    You are reading the v4 documentation. The v3 system is a different object.

    Falsifier

    What would retire it

    Which document is in force: v3 StarkEx or the v4 chain?

03 Sequence

One action, as an operating tape

  1. 01The chain's consensus finalises orders and trades. The v3 StarkEx deployment is a different design and a different document.
  2. 02The insurance fund and the liquidation rule are protocol parameters. This note does not restate their current values.
  3. 03A bridge for USDC or another settlement asset is not the order book. Its trust assumption is separate.

04 Load-bearing

The argument, and where a pitch drops it

  1. What the name has to mean

    The cut

    dYdX v4 moves the perpetual order book onto its own chain, so matching is no longer a set of Ethereum transactions in a smart contract.

    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

    Validator-set assumptions follow the chain they actually ship, which the docs must name.

  2. What actually moves

    The cut

    The insurance fund and the liquidation rule are protocol parameters. This note does not restate their current values.

    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.

  3. What a later deployment may change

    The cut

    A bridge for USDC or another settlement asset is not the order book. Its trust assumption is separate.

    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 has to be true

    You are reading the v4 documentation. The v3 system is a different object.

06 Divergence

What happened after the paper

This is not a statement about the dYdX foundation's governance outcomes.

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.

07 Pre-mortem

What to check before you use the idea

  4. 0 of 3 marked on this browser. A mark is a reading note, not a pass, a rating, or a recommendation.

08 Anatomy

The paper, in the order a builder needs

The problem it names

Leaving Ethereum does not, by itself, change the definition of a perpetual. It changes who orders trades and which light client you must trust.

What the design proposes

  • The chain's consensus finalises orders and trades. The v3 StarkEx deployment is a different design and a different document.
  • The insurance fund and the liquidation rule are protocol parameters. This note does not restate their current values.
  • A bridge for USDC or another settlement asset is not the order book. Its trust assumption is separate.

How the mechanism is specified

  • The chain's consensus finalises orders and trades. The v3 StarkEx deployment is a different design and a different document.
  • The insurance fund and the liquidation rule are protocol parameters. This note does not restate their current values.
  • A bridge for USDC or another settlement asset is not the order book. Its trust assumption is separate.

What this page does not treat as proven

  • No volume, fee, or funding rate is stated here.
  • Validator-set assumptions follow the chain they actually ship, which the docs must name.
  • This is not a statement about the dYdX foundation's governance outcomes.

Why the desk still reads it

dYdX v4 moves the perpetual order book onto its own chain, so matching is no longer a set of Ethereum transactions in a smart contract.

09 Lexicon

Terms, opened into the record

Application-specific chain
A chain whose state machine is the exchange, rather than a general virtual machine hosting an exchange contract.
Perpetual
A position with a funding payment and no expiry. It is not a loan and not a spot trade.
