If you want to customize your request with a specific MEV relay set, you can input a string value into the "relaysSet" field within the "nodesOption" object. There are several MEV relay set options available, including:
- "no_mev": no usage of any MEV relay set
- "non_ofac": usage of MEV relay sets that include non-OFAC compliant transactions
- "ofac": usage of MEV relay sets that include solely OFAC-compliant transactions
- "all": usage of all available MEV relay set
If no option is selected, the default value will be "all".
