AsiaNext Derivatives Trading Service Document

In this context, AsiaNext draws the Members’ attention to the AsiaNext Derivatives Trading Rules stipulating that the Member is responsible for compliance with the applicable laws with respect to the services obtained from AsiaNext.

1. Introduction

AsiaNext (i.e. Asia Digital Exchange Holdings Pte. Ltd. and its subsidiaries) operates separate platforms for the:

(a) trading of cryptocurrency derivatives via Asia Digital Derivatives Pte. Ltd. (ADDE),

(b) listing and trading in Security Tokens via Asia Digital Exchange Pte. Ltd. (ADX) which has obtained the Monetary Authority of Singapore’s (MAS) Recognised Market Operator (RMO) and Capital Market Services (CMS) licenses, and

(c) trading of Digital Payment Tokens via Asia Digital Asset Exchange Pte. Ltd. (ADA) – license application being reviewed by MAS.

Please refer to the respective platforms’ service documents for more information regarding trading of security tokens and digital payment tokens. Operations related queries can be directed to and all other general queries can be directed to

Asia Digital Derivatives Pte. Ltd. (hereinafter referred to as “ADDE”) (LEI: 213800C3T4MEBJ88WM62 and MIC: XAND), a wholly-owned subsidiary of Asia Digital Exchange Holdings Pte. Ltd., which is a joint venture company between SIX Group AG (in Switzerland) and SBI Holdings, Inc. (in Japan), operates a trading platform to trade cryptocurrency derivatives. ADDE operates a central limit order book and only clients meeting eligibility requirements and admitted as a “Member” may access its trading platform.

This document (“Document” or “Service Document”) is intended to provide Members and prospects with a general understanding of ADDE and the derivatives trading platform it operates, how to become a “Member” and member obligations, means of accessing the trading platform, and how to fund and trade cryptocurrency derivatives on ADDE and the margin/settlement requirements.

2. Licensing

MAS has taken the position that payment token derivatives (“PTDs”) (otherwise known as “cryptocurrency derivatives”) as a general asset class are not yet suitable to be regulated and MAS does not regulate PTDs unless they are listed on or offered by an Approved Exchange under the Securities and Futures Act (SFA) 2001 of Singapore. This means that the trading on ADDE is not a regulated or licensable activity in Singapore and, until such time where there are changes to the existing regulations, ADDE is not licensed or regulated by the MAS and hence do not fall within the regulatory purview and oversight of the MAS. Though unlicensed, ADDE will, to the extent possible, adopt similar controls and policies and risk management processes in respect of our operations of the Trading Platform as will be applied to our other regulated or to-be-regulated business operations,

3. Membership

ADDE operates a “members-only” platform for the trading of cryptocurrency derivatives. This means that only institutions admitted to ADDE as “Members” and which have agreed to comply with AsiaNext Derivatives Trading Rules (“Rules”) requirements may access its trading platform and enter orders in cryptocurrency derivatives.

A suspension or termination of a Member or a restriction of Member’s trading access does not in any way affect the liabilities of the Member to AsiaNext and other Members and all such liabilities shall continue until discharged.

4. Maintenance of a Fair, Orderly and Transparent Market

ADDE operates a central limit order book for its trading platform. To promote confidence in its trading platform, it ensures, as far as reasonably practicable, that it operates in a fair, orderly, and transparent manner. To support this, in addition to the undertaking of enforcement actions to ensure compliance with the Rules, ADDE also performs real-time monitoring and market surveillance of its trading platform.

ADDE implements automated market surveillance using tools and processes to detect and prevent, as far as possible any market abuse and market manipulation activities on the trading platform, including wash trading, spoofing, layering and pump-and-dump. This is carried out by monitoring of orders received (including amendment and cancellation of orders) and trades executed for Members on the platform in order to identify possible breaches of the Rules.

ADDE may query a Member on alerts generated by its market surveillance tool, and errant Members may be subject to disciplinary action in accordance with Rule 16.2.

5. Account Structure

ADDE supports proprietary trading by Members as well as trades conducted by Members on behalf of their clients.

For General Members, it must show proof of licensing status (or exempt status) for the provision of agency services to its clients. ADDE will also request for information or documentation evidencing the General Member’s satisfactory controls relating to CDD and AML/CFT matters, including but not limited to Wolfsberg (or other AML) Questionnaire.

5.1 Liquidity Making and Liquidity Taking

Members which have executed ADDE’s liquidity provider agreement (hereinafter referred to as “liquidity providers”) may also take liquidity from ADDE from time to time. They may conduct both types of trading activities through the same account with ADDE.

6.1. Bank Accounts and Funds Flow

Members may establish bank account(s) with banks nominated by ADDE to fund the collateral and margin requirements for derivative trades via internal transfer within the same bank. This would be the preferred way as it facilitates swift sighting of funds by ADDE and eliminates the fiat wire transfer delay. Alternatively, Members shall notify ADDE to whitelist their designated bank account(s) so that it can receive funds withdrawn from ADDE Account, and transfers from Members’ designated bank account(s) can be deposited into ADDE Account for collaterals and margin top-ups via wire transfer. The following diagram illustrates funds flow to/from ADDE Account.

6.1. Bank Accounts Used by ADDE

Presently, ADDE uses Standard Chartered Singapore Limited bank accounts for Members to fund their call accounts for trading and for default fund contribution purposes. Members who also bank with Standard Chartered Singapore Limited or its related branches are able to effect almost instant USD transfers for 22 hours a day, 7 days a week (2 hours downtime each day starting around 10pm to 11pm GMT).

ADDE is also progressing on its efforts to open bank accounts with Customers Bank and Bank Frick, both of which support 24/7 real-time USD internal transfer capability. Members will be notified when ADDE has new bank accounts so that they might be able to effect real-time USD transfers, and ADDE will evaluate the reduction of minimum deposit for these Members.

Members will not be able to view their cash balances in ADDE Account via a web interface. They should refer to the hourly settlement run reports that are automatically generated and emailed to Members or pull the required information via ADDE REST API connectivity.

6.2. Holding of Members’ Funds

Members’ funds including margins and excess collateral in their call accounts are held in reputable and regulated bank accounts in the name of ADDE. These Members’ funds are not commingled with ADDE’s and AsiaNext’s own corporate funds, and it cannot be used by ADDE for the payment of ADDE’s or AsiaNext’s debts (if any). Between ADDE and the Member, the Member’s funds can only be applied solely for the purposes agreed to by Members. Finally, Members’ funds cannot be transferred out except where the transfer is in accordance with the Members’ written instructions obtained prior to each transfer, or is permitted under ADDE Trading Rules, or is authorised by law. However, do note that, in the case where Members’ funds are held in a bank in the name of ADDE, it is not safeguarded or held on trust by the bank for ADDE’s customers and, as such, in the event of insolvency of ADDE the Member will only have an unsecured claim against ADDE for the monies held with ADDE.

A different Standard Chartered Singapore Limited USD account is used to receive Members’ default fund contributions.

7. Trading interfaces: Binary, FIX, REST and Webtrader

ADDE offers 4 interface options for Members to trade and manage their transactions and information flow.

1. Binary connections (via AWS PrivateLink or Extranet / POP)
2. FIX connections (via AWS PrivateLink or Extranet / POP)
3. AsiaNext Binary Bridge to REST (ABBR)
4. Front-end Trader web application

Binary connections: For clients that require low latency, a proprietary binary protocol is available for an efficient, streamlined, and low latency order entry and trading activity.

FIX connections: An enhanced FIX 4.2 protocol is supported.

For clients connecting via binary or FIX, a drop copy service is provided for reporting trading activities.

ABBR: For clients on REST, an AsiaNext Binary Bridge to REST (ABBR) is available. The order entry data is converted from REST to binary protocol before submission to the matching engine. Market data is provided via WebSockets (WSS).

7.2.2. Authentication and Refresh Tokens

Members are required to send a HTTP POST login request to ADDE authentication API. The response received by the Member will contain the Authentication Token and the Refresh Token. The default expiry times are set to 5 minutes for the Authentication Token and 30 minutes for the Refresh Token, and can be changed. If the authentication token expires, the Member is required to send a HTTP POST Refresh request with the refresh token in the authorization section of the request’s header.

7.2.3. Message Signing

ADDE uses the JSON Web Signature (JWS) standard for creating digitally signed and encoded JSON objects. A JWS consists of three parts:

(a) Header – contains information about the algorithm used to create the signature, as well as any additional information that is needed.

(b) Payload – the actual data being transmitted.

(c) Signature – a hash of the header, payload, and a secret key that is shared between the sender and the receiver.

Each message that is sent through the ADDE Post-Trade API needs to be signed with an authentic Secret Key that will be supplied by ADDE to the Member. Once signing has successfully taken place, the JWS will be sent in the body of the HTTP Request in the form of a JSON string. The Post-Trade API can then verify the signature using the same secret key and algorithm specified in the header, and decode the header and payload to access the data transmitted in the JWS. The Post-Trade API uses token-based Authentication. For the below HTTP calls to be successful, the Member needs to populate the “Authorization” header, of the message being sent, with the Authentication token (accessToken) received from the Authentication API on Login or Refresh.

8. Infrastructure and Cyber Security

ADDE has implemented comprehensive controls and procedures to mitigate impact from any system failure to ensure the smoothest possible and uninterrupted operation of the trading venue to its Members.

(a) Infrastructure is resilient by design with hardware and connectivity redundancies across various Availability Zones that are resilient to single site failure

(b) Rigorous system testing

(c) Micro network segmentation

(d) Multi-layered defence to block attacks at multiple layers

(e) Proactive health checks and regular system patching

(f) Security Information and Event Management via 24×7 monitoring of systems and cloud service providers, threat detection and prevention

(g) Automated and regular patching to ensure systems are up-to-date

(h) Regular vulnerability scans and penetration tests

(i) System backup and recovery

(j) Regular Disaster Recovery / Business Continuity Plan exercises

(k) ADDE’s engaged cloud service provider, Amazon Web Services (AWS), is resilient and independently verified to have met Threat, Vulnerability and Risk Assessment. AWS is also compliant with MAS’ Technology Risk Management requirements.

9. Crypto Derivative Products, Contract Expiry and Position Settlement

ADDE cryptocurrency (or “DPT” or “digital payment token”) Derivative Contracts (“Contracts”) shall have the following settlement and valuation process:

(a) Upon contract expiry, final settlement will be via cash debit or credit.

(b) The Final Settlement Price shall be the Settlement Reference Rate at 4 p.m. UTC on the expiry date calculated based on the last hourly VWAP (Volume Weighted Average Price) of the underlying cryptocurrency taken from whitelisted crypto exchanges (as defined in the SIX Reference Rate Crypto Indices methodology).

(c) Members holding Open Positions at the contract expiry shall make payment to or receive payment from ADDE in accordance with the margin procedures, based on the Final Settlement Price.

(d) In the event of a hard fork, the affected Contract shall continue to settle to the Settlement Reference Rate corresponding to the original DPT / fiat pair (i.e. BTC/USD or ETH/USD). ADDE may in its sole discretion take alternative action with respect to hard forks (including potential trading halt during the hard fork period) in consultation with the Members as appropriate.

Presently, Members are unable to query the historical Final Settlement Prices via REST endpoints but ADDE will consider providing this feature to allow Members to readily reconcile their trades profit and loss via API calls.

Perpetual Futures do not have any fixed expiry date and settlement is conducted in the same manner as it would be done for pre-expiry futures contracts.

9.1. Funding Rate for Perpetual Futures

The funding rate is calculated and paid or received every hour. When the funding rate is positive, long position holders pay funding to the short position holders; when the funding rate is negative, short position holders pay funding to the long position holders. The following rules apply to the funding rate:

Calculation of Impact Volume Weighted Average Bid/Ask price is described as follows:

(a) Set an Impact Quantity on the number of contracts. The Impact Quantity is used to locate the average Impact Bid or Ask price in the order book.

Calculate P𝐵𝐼𝐷, P𝐴𝑆𝐾 using volume weighted average Bid/Ask price from the order book where volume is up to the Impact Quantity as determined in step 1

The Impact Bid and Ask are calculated when both are simultaneously available on the hour; else the next most recent observation is used.

(b) Determine funding rate based on the above rules. The actual funding payment/receipt is calculated by multiplying the funding rate with the position size.

The resulting hourly funding rate is subject to appropriate cap and floor values. This means that if the hourly funding rate calculated is above the cap or below the floor, it would be adjusted to the cap or floor respectively.

9.2. Novation to ADDE

Under the Rules, all trades in cryptocurrency derivatives on ADDE’s trading platform will be novated to ADDE such that there will be two resulting contracts (identical to the original contract) – one contract between the selling Member and ADDE, and one contract between the buying Member and ADDE. Please refer to Rule 10 (Novation and Settlement) of the Rules for details.

As the central counterparty to each of the selling Member and buying Member, ADDE replaces the original parties to the trade. This has the effect of facilitating post-trade anonymity, simplifying the settlement process, and eliminating the bilateral relationship between the original parties to the trade and, in doing so, remove the buying and selling Members’ counterparty risk against each other from trade until final settlement of the contract.

During the lifetime of the trade between trading and final settlement, ADDE manages or facilitates trade management, position management, risk management, and settlement calculation and facilitates the settlement process. The counterparty risk is mitigated through margining requirements, using best-practice risk models, and setting high risk management standards.

9.3. Settlement and Clearing Aggregation/Netting

ADDE aggregates and nets all gross settlement transactions of the Member on Contract expiry day and creates one net settlement transaction per instrument, currency, and settlement date on the respective settlement account.

ADDE allows for netting or offset of all open interest of Contracts in computing a Member’s initial margin requirement at each instrument class (BTC or ETH). Members are margined on a net basis by aggregating the initial margin across all Contract products within ADDE.

9.4. Settlement Participants

A settlement participant is a party that has entered into an agreement with ADDE to participate in the settlement of the derivatives trades executed on its own account and/or on trades carried out by other parties. ADDE acts as the Central Counterparty in the trade executed on its platform between two Members. The Member will (as default) be a settlement participant on the platform itself.

9.5. Final Settlement Price

ADDE shall determine the Final Settlement Price for each Contract (to which final settlement applies) in accordance with the relevant formulae and procedures set out in the relevant Contract Specifications. The Final Settlement Price so determined by ADDE shall be final.

If, for any reason, the relevant index or other value on which final settlement of any Contract is based is not published at the end of the Last Trading Day for such Contract, or ADDE believes there is an error in the calculation of the index or other value, or ADDE is otherwise unable to issue a final settlement price on such trading day and alternative settlement procedures are not otherwise specified in the relevant Contract Specifications, then ADDE may:

(a) postpone the determination of the Final Settlement Price until such time as the relevant pricing data (as set out in the applicable Contract Specifications and Specific Contract Rules) is available for up to the duration set out in the applicable Contract Specifications and Specific Contract Rules; or

(b) determine a Final Settlement Price that reflects the true market value at the time of final settlement based upon another pricing source or otherwise in a commercially reasonable manner.

9.6. Matching of Order Instructions

Members shall have the following order fields available to send in their orders to ADDE for order matching:

  • Transaction type: [Buy] or [Sell]
  • Order type:
    • [Limit order] for buying or selling contract at a specific price or better.
    • Post-Only (PO) and Post-Only Cancel Replace (POCR) Orders are enabled only for liquidity providers. They are specified using the custom FIX tag AquisOrderAttribute (27010) on the New Order Single message, and as u8 orderType in ADDE’s binary protocol, Aquis Trading Protocol (ATP).
  • Time-in-Force:
    • Good-Till-Date or [GTD] (up to contract expiry date)
    • Immediate or Cancel or [IOC]: Immediate fulfilment of whole or partial order against available resting orders. Unfulfilled order portion will be cancelled
    • Fill or Kill or [FOK]: Immediate execution of the whole order against resting order. Unexecuted order will be cancelled.

Orders received from the Members shall be matched with available resting orders based on price time priority. Price priority will cross and match the incoming buy order with the best price (i.e. lowest sell price) on the resting sell order queue. Conversely, the incoming sell order will be crossed and matched with best price (i.e. highest buy price) on the resting buy order queue. Time priority will cross and match the incoming order with the earliest resting order or orders received if there are multiple resting orders with the order limit price.

The price of the executed trade will be determined based on the resting order limit price or resting orders’ volume-weighted limit prices that is / are crossed and matched with the incoming order i.e. trade price will be based on maker order price.

Self-trade prevention will be imposed on liquidity providers to prevent their own orders from crossing in the matching engine on price time priority. If an incoming (or price modified) order would trade with another order from that liquidity provider that is already in the AsiaNext order book, the existing resting order is automatically cancelled. The incoming order may trade with other orders, or is posted to the order book, as normal.

10. Risk Management

In its role as a central counterparty, ADDE provides robust and comprehensive risk management framework to ensure the financial performance of every cleared trade.

ADDE has established a risk management system to monitor and measure the risk exposure of its Members.

The risk management framework includes a dedicated margin methodology to perform the quantitative assessment of the inherent market risk and incorporate additional margin layers to cater for liquidity, concentration, and stress testing.

To enhance the continuous operation and the integrity of the platform, ADDE offers a 24/7, hourly margining & settlement cycle to effectively manage the overall liquidity and counterparty risk of ADDE. The overall margining process can be funded with USD fiat and eventually (Day 2) with an acceptable digital fiat or stablecoin collateral offered by well-established financial institutions.

10.1. Margining, Mark-to-Market, Limits Breach and Margin Call

10.1.1. Margining Process

Margin represents assets held as collateral against any financial obligation relating to its open positions in derivative contracts. Margins are calculated to cover current and potential exposures on all open positions.

ADDE maintains both Initial Margin and Minimum Deposit in prescribing minimum margin and collateral requirements respectively for its Members.

Initial Margin represents the minimum margin that ADDE requires from Member for newly entered positions and it includes margin and margin add-ons.

Minimum Deposit applies only to Members who are not settling hourly margin requirements as calculated by ADDE and represents the minimum collateral level in the call account that ADDE requires from Members, over and above Initial Margin and Margin add-ons. Minimum Deposit requirement accounts for the longer default margin period of risk exposure. The table below is an illustration of possible Initial Margin and Minimum Deposit levels under different settlement arrangements.

* Daily settlement clients refers to clients who request to answer margin call/pull once per day despite the system hourly margining cycle.

** Initial Margin and Minimum Deposit levels are indicative for illustration purpose only and may change subject to market price volatility.

ADDE will request from Members excess collaterals if the cash on deposit falls below the Minimum Deposit level computed by ADDE. In such cases, a deposit top-up notification will be issued to top up the call account cash back to the minimum deposit level. ADDE will issue margin call notification if the cash is unable to meet the margin required for the hourly settlement run. Member’s account will be temporarily suspended and Member is expected to top up the cash account within a grace period. Beyond the grace period, the account may be partially liquidated to reduce the net open positions and regularize the margin call status. In accordance with section 3.6.3 Effect of Termination or Suspension in this document, margin requirements shall continue to apply to a Member that is suspended by ADDE insofar as the Member having any open position. The suspended Member’s margin requirements shall continue to be calculated and the suspended Member shall fulfill any margin call that is issued to it by ADDE.

All deposits posted by Members in their account with ADDE for meeting margin and Minimum Deposit requirements shall not bear any interest.

10.1.2. Margin Requirements and Mark-To-Market

ADDE uses a Value at Risk (VaR) based margin model with a single tailed confidence level of 99% derived from (filtered) historical simulations. The margin model seeks to cover estimated distribution of future exposure in pre-specified liquidation periods.

Margin add-ons such as liquidity add-on, concentration or large exposure add-on and credit risk add-on or other risk add-ons may also be applied.

The total initial margin requirement for each Member, which includes the margin for future exposure and the add-ons, will be processed at each settlement cycle.

ADDE conducts Mark–To- Market process and revalues all open positions during each settlement cycle. Gains and losses for futures and options are collateralized together with the margin requirement. Futures contracts are marked to market based on trading activity or order book snapshot or a Reference Rate on ADDE between each hour, i.e. between HH:00:00 and HH:59:59. The table below elaborates the methodology.
