General

These docs describe the v3 API for the dYdX decentralized perpetual contracts exchange. The exchange runs on an L2 (layer-2) blockchain system, and operates independently of previous dYdX protocols and systems, including the v1 and v2 APIs.

Like the previous iteration of dYdX perpetuals, the exchange uses a centralized order book, but remains non-custodial, and settles trades and liquidations in a trustless manner.

Layer 2: ZK-Rollups

Trades are settled in an L2 (layer-2) system, which publishes ZK (zero-knowledge) proofs periodically to an Ethereum smart contract in order to prove that state transitions within L2 are valid. Funds must be deposited to the Ethereum smart contract before they can be used to trade on dYdX.

By settling trades on L2, the exchange is able to offer much higher trade throughput and lower minimum order sizes, compared with systems settling trades directly on Ethereum (i.e. L1). This is achieved while maintaining decentralization, and the exchange is fully non-custodial.

The L2 system was developed with, and is operated jointly with, Starkware. More information about the L2 design can be found in Starkware's documentation. (Note: Some of the details described there may be specific to Starkware's previous StarkEx system and may not apply to the dYdX system.)

Data Centers

Our data centers are located in the Amazon us-east-1 region (Northern Virginia).

Number Formats

All amounts and prices in the clients and API are represented in “human readable,” natural units. For example, an amount of 1.25 ETH is represented as 1.25, and a price of $31,000.50 per BTC is represented as 31000.5.

This differs from the dYdX v1 and v2 APIs which represented amounts and prices in terms of base token units.

Base URLs

Base URLs for API endpoints are as follows:

Perpetual Contracts

The dYdX Perpetual is a non-custodial, decentralized margin product that offers synthetic exposure to a variety of assets.

Margin

Collateral is held as USDC, and the quote asset for all perpetual markets is USDC. Cross-margining is used by default, meaning an account can open multiple positions that share the same collateral. Isolated margin can be achieved by creating separate accounts (sub-accounts) under the same user.

Each market has two risk parameters, the initial margin fraction and the maintenance margin fraction, which determine the max leverage available within that market. These are used to calculate the value that must be held by an account in order to open or increase positions (in the case of initial margin) or avoid liquidation (in the case of maintenance margin).

Portfolio Margining

There is no distinction between realized and unrealized PnL for the purposes of margin calculations. Gains from one position will offset losses from another position within the same account, regardless of whether the profitable position is closed.

Margin Calculation

The margin requirement for a single position is calculated as follows:

Initial Margin Requirement = abs(S × P × I)
Maintenance Margin Requirement = abs(S × P × M)

Where:

The margin requirement for the account as a whole is the sum of the margin requirement over each market i in which the account holds a position:

Total Initial Margin Requirement = Σ abs(Si × Pi × Ii)
Total Maintenance Margin Requirement = Σ abs(Si × Pi × Mi)

The total margin requirement is compared against the total value of the account, which incorporates the quote asset (USDC) balance of the account as well as the value of the positions held by the account:

Total Account Value = Q + Σ (Si × Pi)

The Total Account Value is also referred to as equity.

Where:

An account cannot open new positions or increase the size of existing positions if it would lead the total account value of the account to drop below the total initial margin requirement. If the total account value ever falls below the total maintenance margin requirement, the account may be liquidated.

Free collateral is calculated as:

Free collateral = Total Account Value - Total Initial Margin Requirement

Equity and free collateral can be tracked over time using the latest oracle price (obtained from the markets websocket).

Liquidations

Accounts whose total value falls below the maintenance margin requirement (described above) may have their positions automatically closed by the liquidation engine. Positions are closed at the liquidation price described below. Profits or losses from liquidations are taken on by the insurance fund.

Liquidation Price

The liquidation price of a position is calculated as follows, depending on whether it is a short or long position:

Liquidation Price (short) = P × (1 + M × V)
Liquidation Price (long) = P × (1 − M × V)

Where:

This formula is chosen such that the ratio Total Account Value / Total Maintenance Margin Requirement is unchanged as individual positions are liquidated.

Funding

Funding payments are exchanged between long and short traders to encourage the price of a perpetual contract to trade close to the price of the underlying. If the perpetual trades at a premium relative to the index, long traders will typically make payments to short traders, whereas if the perpetual trades at a discount relative to the index, short traders will typically make payments to long traders.

The payments are credited or debited at the start of each hour, and are included in the realized PnL for the position.

Funding payments can be found by calling Get /v3/funding and the predicted funding rate can be found by calling Get v3/markets.

Funding Rate Units

Since funding payments are exchanged every hour, the dYdX funding rate is usually represented as a 1-hour rate, which represents the return a position may expect to earn or pay every hour.

When calculating the funding rate, the premium is scaled to have a realization period of 8 hours. That means, for example, that if a certain perpetual market trades consistently at a 0.1% premium relative to the underlying, long traders may expect to pay ~0.1% every 8 hours, and short traders may expect to earn a ~0.1% return every 8 hours (not accounting for the interest rate component).

Funding Payment Calculation

At the start of each hour, an account receives USDC (if F is positive) or pays USDC (if F is negative) in an amount equal to:

F = (-1) × S × P × R

Where:

Funding Rate Calculation

The main component of the funding rate is a premium that takes into account market activity for the perpetual. It is calculated for each market, every minute (at a random point within the minute) using the formula:

Premium = (Max(0, Impact Bid Price - Index Price) - Max(0, Index Price - Impact Ask Price)) / Index Price

Where the impact bid and impact ask prices are defined as:

Impact Bid Price = Average execution price for a market sell of the impact notional value
Impact Ask Price = Average execution price for a market buy of the impact notional value

And the impact notional amount for a market is:

Impact Notional Amount = 500 USDC / Initial Margin Fraction

For example, for a market with a 10% initial margin fraction, the impact notional value is 5,000 USDC.

At the end of each hour, the premium component is calculated as the simple average (i.e. TWAP) of the 60 premiums calculated over the course of the last hour. In addition to the premium component, each market has a fixed interest rate component that aims to account for the difference in interest rates of the base and quote currencies. The funding rate is then:

Funding Rate = (Premium Component / 8) + Interest Rate Component

Currently, the interest rate component for all dYdX markets is 0.0000125% (equivalent to 0.0001% per 8 hours).

Contract Loss Mechanisms

During periods of high volatility in the markets underlying the perpetual contracts, the value of some accounts may drop below zero before they can be liquidated.

The insurance fund is the first backstop to maintain the solvency of the system when an account has a negative balance. The account will be liquidated, and the insurance fund will take on the loss.

In the event that the insurance fund is depleted, positions with the most profit and leverage may be used to offset negative-balance accounts, in order to maintain the stability of the system.

Clients

Python and TypeScript clients are available, allowing programmatic usage of dYdX.

Python Client

Installation

Install dydx-v3-python from PyPI using pip:

pip install dydx-v3-python

API

See dydxprotocol/dydx-v3-python.

TypeScript Client

Installation

Install @dydxprotocol/v3-client from NPM:

npm i -s @dydxprotocol/v3-client

API

See dydxprotocol/v3-client.

Client Initialization

Initialize

client = Client(
    host='https://api.dydx.exchange',
    web3=Web3('...'),
    stark_private_key='01234abcd...',
)
const client: DydxClient = new Client(
    'host',
    {
        apiTimeout: 3000,
        starkPrivateKey: '01234abcd...',
    },
);

The client is organized into modules, based on the type of authentication needed for different requests. The configuration options passed into the client determine which modules are available. See Authentication for more information.

Module Description
public Public API endpoints. Does not require authentication.
onboarding Endpoint to create a new user, authenticated via Ethereum key.
api_keys Endpoints for managing API keys, authenticated via Ethereum key.
private All other private endpoints, authenticated via API key.
eth Calling and querying L1 Ethereum smart contracts.

The following configuration options are available:

Parameter Description
host The HTTP API host.
api_timeout Timeout for HTTP requests, in milliseconds.
default_ethereum_address (Optional) The default account for Ethereum key auth and sending Ethereum transactions.
eth_private_key (Optional) May be used for Ethereum key auth.
eth_send_options (Optional) Options for Ethereum transactions, see sendTransaction.
network_id (Optional) Chain ID for Ethereum key auth and smart contract addresses. Defaults to web3.net.version if available, or 1 (mainnet).
stark_private_key (Optional) STARK private key, used to sign orders and withdrawals.
web3 (Optional) Web3 object used for Ethereum key auth and/or smart contract interactions.
web3_account (Optional) May be used for Ethereum key auth.
web3_provider (Optional) Web3 provider object, same usage as web3.
api_key_credentials (Optional) Dictionary containing the key, secret and passphrase required for the private module to sign requests.
crypto_c_exports_path (Optional) For python only, will use faster C++ code to run hashing, signing and verifying. It's expected to be compiled from the crypto_c_exports target from Starkware's repository. See section on this below for more information.

C++ Methods for Faster STARK Signing

The C++ wrapper methods in the client expect an absolute path to a Shared Object. This has to be compiled from Starkware's crypto C++ library.

Private HTTP API

Authentication

There are three levels of authentication to be considered when using dYdX. All signing can be handled directly by the client libraries.

Ethereum Key Authentication

The highest level of authentication is via an account's Ethereum private key. The Ethereum key remains in control of an account's funds while they are within the L2 system. This includes the ability to forcibly close an account's positions and exit the system, in the event that the L2 operators (dYdX and Starkware) were to unexpectedly go offline or otherwise censor requests.

Ethereum key authentication is required for the following operations:

STARK Key Authentication

Within the L2 system, authentication is handled by a separate key pair, known as the account's STARK key pair.

STARK key authentication is required for the following operations:

API Key Authentication

The third level of authentication consists of the API key, secret and passphrase which are used solely to authenticate API requests made to dYdX. This includes operations such as canceling orders or retrieving an account's fills, which do not affect the L2 system.

When a user onboards via POST v3/onboarding, the server will use the signature as a seed to determinstically generate default API key credentials. An API key includes three fields:

API keys can be added and managed via the /v3/api-keys endpoints.

All requests which are not signed by an Ethereum key and which are made to private endpoints require an API key signature.

STARK Key Cryptography

The STARK and API keys are ECDSA key pairs on the STARK curve. More info on the cryptography used on L2 is available in Starkware's documentation.

Creating and Signing Requests

Within the private HTTP API, there are three groups of endpoints which each require different headers and authentication.

(Separately, and in addition to the above, STARK signatures are required for orders and withdrawals. For details, please refer to the Python and TypeScript reference implementations.)

Onboarding Endpoint: POST v3/onboarding

Request Headers

Header Required? Description
DYDX-SIGNATURE yes Ethereum key authentication
DYDX-ETHEREUM-ADDRESS yes Ethereum address of the user

Signing

The header DYDX-SIGNATURE is an EIP-712 Ethereum signature on a static message containing the fields:

See reference implementations: [Python] [TypeScript]

Ethereum Key Private Endpoints

This group includes the POST and DELETE v3/api-keys endpoints for managing API keys. Like the onboarding endpoint, requests to these endpoints require signatures by the user's Ethereum key.

Request Headers

Header Required? Description
DYDX-SIGNATURE yes Ethereum key authentication
DYDX-ETHEREUM-ADDRESS yes Ethereum address of the user
DYDX-TIMESTAMP yes ISO timestamp of when the request was signed. Must be within 30 seconds of the server time.

Signing

The header DYDX-SIGNATURE is an EIP-712-compliant Ethereum signature on a message containing the fields:

See reference implementations: [Python] [TypeScript]

API Key Private Endpoints

All private endpoints not listed above fall in this category, and must be authenticated via an API key.

Request Headers

Header Required? Description
DYDX-SIGNATURE yes HMAC of the request
DYDX-ETHEREUM-ADDRESS yes Ethereum address of the user
DYDX-TIMESTAMP yes ISO timestamp of when the request was signed. Must be within 30 seconds of the server time.
DYDX-PASSPHRASE yes The passphrase field of the API key.
DYDX-ACCOUNT-NUMBER no Account number used to scope the request. Defaults to zero.

Signing

The DYDX-SIGNATURE is a SHA-256 HMAC produced as described below, and encoded as a Base64 string.

A SHA-256 HMAC is created using the API key secret and the message timestamp + method + requestPath + body defined as follows:

The HMAC should be encoded as a Base64 string and sent as the DYDX-SIGNATURE header.

See reference implementations: [Python] [TypeScript]

Rate Limits

If more than 100 requests are made in 10 seconds, requests will be blocked for one minute. Please make use of the WebSockets API if you need real-time data.

Onboarding

Overview

A few steps are required of all accounts before they can begin trading:

  1. Create a user, providing a STARK public key to be associated with the main account.
  2. Request registration signature from dYdX.
  3. Send registration request to the L1 smart contract.
  4. Approve collateral token allowance on the L1 smart contract.
  5. Deposit collateral token to the L1 smart contract.

All of these steps are supported by the Python and TypeScript clients. See the Python integration tests for an example of onboarding and usage of various endpoints.

Fast vs. Slow Withdrawal

The normal process for withdrawing from L2 to L1 requires waiting for a block of L2 transactions to be collected, and the zero-knowledge proof for the bock to be constructed and verified on-chain.

Using the fast withdrawal process, users can get their funds on L1 much faster by essentially trading their L2 funds to an “LP” account operated by dYdX, in order to receive immediate liquidity on L1. Since the LP must then recycle these funds from L2 to L1 via the regular withdrawal process, dYdX is only able to process a certain volume of fast withdrawals within a given period of time.

Response

Parameter Description
order See order.

Order LimitFee

The limitFee is the highest fee a user would be willing to accept on an order. This should be in decimal form (i.e. 0.1 is 10%). To see current fees, call GET /v3/users and the maker/taker fee rates show what fees will be. If the order is postOnly dYdX will validate against makerFeeRate only. The opposite is true if the order is FOK or IOC - dYdX will only validate against takerFeeRate. Otherwise, dYdX assesses against the maximum of maker and taker fee rate.

Tick Size and Minimum Size

Tick Size

Each market has a specified tickSize. Order price must be a multiple of the tickSize. THe same applies to triggerPrice and trailingPercent if either of these are not null.

Minimum Size

Each market has a specified minOrderSize. Order size must be not be less than the minOrderSize.

Order Deletion

Canceled orders older than one month are deleted from the dYdX database.

Orderbook

To subscribe:

field type description
type string Set to subscribe
channel string Set to v3_orderbook
id string The market to subscribe to e.g. BTC-USD, LINK-USD
includeOffsets (optional) boolean If specified, this will return an initial response with per-price level offsets

Initial Response:

The initial response will contain the state of the orderbook and will be the same structure as GET /v3/orderbook/:market. If includeOffsets is sent and set to true in the subscription message, there will be an offset included for each price level. (See the example included)

field description
type will be subscribed
channel the channel name, i.e. v3_orderbook
id the market subscribed to e.g. BTC-USD
contents the message contents

The contents is structured as:

field type description
offset string A number used for ordering. See offset below.
bids array See PublicOrder below. Sorted by price in descending order
asks array See PublicOrder below. Sorted by price in ascending order

PublicOrder:

field type description
price string human readable price of the order (in quote / base currency)
size string human readable size of the order (in base currency)
offset string (if includeOffsets is set to true) the offset for the specific price

Offset:

The price updates are not guaranteed to be sent in order. So it is possible to receive an older price update later. For this reason, the offset is included in the message, to help order. The offset increases monotonically, and increasing values of offsets indicate more recent values.

Example messages:

Example initial response:

      },
      {

Example initial response if includeOffsets is set to true:

Request:

{
  "type": "subscribe",
  "channel": "v3_orderbook",
  "id": "ETH-USD",
  "includeOffsets": "true"
}

Response:

        "offset": "36848433",
        "size": "4.3"
      }
    ]
  }
}

Channel Data

Subsequent responses will contain the new order sizes for any price levels that have changed since the previous update:

e.g:

Subsequent messages

{
  "type": "channel_data",
  "id": "BTC-USD",
  "connection_id": "e2a6c717-6f77-4c1c-ac22-72ce2b7ed77d",
  "channel": "v3_orderbook",
  "message_id": 2,
  "contents": {
    "offset": "178",
    "bids": [["102", "12"]],
    "asks": [["104", "0" ]]
  }
}

E.g: if some orders at "102" price, get filled, then the update would be ["102", "12"], where "12" is the new size. If there are no more asks at "104", then the ask update would be ["104", "0"].
