Members should make sure they are familiar with the ErisX Rulebooks which detail the rules that Members must abide by when participating in or entering Block Trades.
A Block Trade is the sale or purchase of a specified quantity of an asset at a defined price that is negotiated directly between two parties. ErisX allows its Members to submit Block Trades to the exchange in order to record, process and settle the trade via ErisX’s Exchange and Clearinghouse. This improves and simplifies Members’ workflows, enables many-to-many trading and mitigates settlement risk, while minimizing operational and paperwork burdens.
Block Trades executed via ErisX are subject to a series of rules that differ from the trades executed on ErisX’s Central Limit Order Book. Before using ErisX Block Trade capabilities, Members should make sure they are familiar with the ErisX Exchange Rulebook Rule 601 and Rule 1206, which detail the rules that Members must abide by when participating in or entering Block Trades.
Block Trade Permissions
By default, Members are not allowed to enter into Block Trades. Members who are interested in being enabled to submit Block Trades, must contact the ErisX Client Services team to discuss adding Block Trade permissions to your Member account.
The permissions for entering or participating in Block trades on ErisX are divided across Members and Users profiles.
Before any account under a Clearing Member can enter or participate in a Block Trade, the Clearing Member must have Block Trade permissions enabled (for Spot and/or Futures).
Before any User can enter a Block Trade, the User must have the Block Trade permission enabled.
Note: To participate in Futures Block Trades each participant must be an Eligible Contract Participant.
Block Trade Submission
ErisX offers two options to submit Block Trades:
Via REST API
Via the ErisX Trading UI
Members may choose the method that better suits their needs. The documentation describing the API methods to submit Block Trades can be found in the ErisX REST API documentation.
Note: only one of the participants involved in the Block Trade submits the Block Trade for both parties.
In order to submit a Block Trade using the ErisX Trading UI, Members should follow the steps below. Note that Block Trade Submission is available in both Desktop and mobile versions of the ErisX Trading UI.

ErisX Members can source liquidity to execute large orders via the ErisX streaming OTC service. This new service is fully supported via the ErisX Trading UI as well as the WebSocket API. Members can login to the ErisX Trading UI and request a quote for a specific asset and quantity. Immediately after, quotes will start streaming for the given asset and quantity. Clients can interact with the quotes and execute them. Once the quote is executed, the trade is cleared and settled by the ErisX Clearinghouse instantly on the Member’s ErisX account.
This simplified workflow implemented by ErisX eliminates OTC counterparty risk for ErisX Members and the burden of AML/KYC processes between Members and liquidity providers typical of bilateral agreements. Moreover, ErisX’s Clearinghouse is responsible for clearing and settling the trade, which is done instantly, thus eliminating complex settlement processes and unnecessary blockchain, bank interactions and their associated costs.
Eliminate counterparty risk and settle instantly
The ErisX Clearinghouse eliminates the challenges of counterparty risk and complex settlement workflows associated with bilateral OTC trading. ErisX’s simplified workflow enables users to execute OTC quotes which are cleared and settled instantly in the ErisX account.
Eliminate independent counterparty AML/KYC reviews
All ErisX Members are subject to AML and KYC reviews by the Clearinghouse. Clearing Members can trade with all other clearing Members without the need to do independent AML/KYC reviews for each counterparty.
Accessible via Trading UI and API
ErisX OTC quote streams and executions are fully supported in the ErisX Trading UI, so you don’t need any development work to start using it. It is also fully supported in the ErisX Websocket API, which enables you to customize your implementation.
