Required Documentation

The following documentation is required to complete Phase 1 onboarding for U.S.-based Entities. Natural Persons should see the Entity vs. Natural Person section below; international entities have similar requirements. All documents must be submitted alongside your completed Phase 1 Onboarding Requirements Form, and your legal entity name must appear consistently across all documents.

Entity documentation checklist

Document	Requirements
Organizational Document	Articles of Incorporation, Certificate of Incorporation, Certificate of Formation, Articles of Organization, Business Registration Certificate, Business License, or Certificate of Registration. The business name must match your full legal entity name.
Form W-9	Must reflect your full legal entity name as you are registering with ElectronX.
Certificate of Good Standing (or equivalent)	Must be current and dated within the last year. Business name must match.
Proof of Authorized Signature	On company letterhead, listing all individuals authorized to sign legal documents on behalf of your entity, or a more formal company resolution that provides the same information. If the document references an affiliated entity name rather than the onboarding entity, confirm the affiliation by email.
Government-Issued ID for each UBO	Required for any natural person who ultimately holds 25% or more ownership, directly or indirectly, of the entity you are onboarding. Acceptable forms: front and back of a Driver's License, State ID, or Passport Card; or a photo of the bio page of a Passport.
Control Person ID	Government-issued ID for the designated control person.

Ultimate Beneficial Owners (UBOs)

An Ultimate Beneficial Owner is any natural person or entity that ultimately holds 25% or more ownership of your business, whether directly or through holding or intermediary companies. You are required to disclose all UBOs regardless of how they hold their interest.

If your entity has no UBOs holding 25% or more, please indicate as such on the form. For each natural person UBO, you will need to provide their name, percentage ownership, email address, and a government-issued ID. For each entity UBO, you will need to provide the entity legal name and ownership percentage, and disclose whether that entity is itself held by individuals or entities with 25% or more ownership.

US Agent for Service of Process

All applicants are required to provide contact details for a US Agent for Service of Process, as required under the Participant and Clearing Member Agreement. Your US Agent may be an internal staff member or employee based in the US, or a US-based third-party registered agent. You will need to provide their full name, address, email, and phone number.

Control person information

All applicants are required to provide details of a designated Control Person. This is a person with significant managerial control or influence over a legal entity customer (e.g., Chief Executive Officer, Chief Financial Officer, Managing Member, General Partner, etc.). You must provide the information of one control person for your business, including: name, job title, email address, phone number, percentage of ownership (if this individual is also an owner), along with a photo of government ID (see the checklist above).

Other entity requirements

• Business Name
• Business EIN
• Business Address
• Form Filler Information (name, job title, email address, phone number)
• Answers to Certifications and Attestation Questions

Entity vs. Natural Person onboarding

ElectronX accepts both Entity applicants and Individual (natural person) applicants. The onboarding process follows the same two-phase structure for both, but the documentation requirements and some account mechanics differ. The table below summarizes the key differences.

Legal identifier	Business EIN	Social Security Number
Address	Registered business address	Personal residential address
Organizational documents	Required (Articles of Incorporation, Business Registration Certificate, etc.)	Not required
Form W-9	Entity W-9 - business name must match exactly	Personal W-9
Certificate of Good Standing	Required - must be dated within the last year	Not required
Proof of Authorized Signature	Required - on company letterhead listing all authorized signatories	Not required - individual signs on their own behalf
UBO disclosure	Required for any natural person or entity holding 25%+ ownership, directly or indirectly	Not required - the applicant is the beneficial owner
Government-issued ID	Required for each UBO natural person and the Control Person	Required - one government-issued photo ID for the applicant
US Agent for Service of Process	Required - may be internal staff or a third-party registered agent	Required - may be the applicant themselves if US-based, or a US-based third party
Banking Information	Provided in Phase 2	Provided in Phase 1
Authorized User status	Designated in Phase 2 - can be assigned to any authorized individual	The applicant is automatically an Authorized User, Risk User, and Operations User

Natural Person: onboarding requirements

Individual applicants complete a version of the Phase 1 form adapted for natural persons. You will provide your full legal name, SSN, personal address, and contact details. Your government-issued ID serves as identity verification in place of organizational documents. You will also provide contact details for a US Agent for Service of Process (which may be yourself if you are US-based), your bank account details for funding and withdrawals, and your preferred trading access method (GUI, API, or both).

Accepted government-issued ID types

For natural person applicants, and for UBO natural persons and the designated Control Person in entity applications, the following forms of identification are accepted:

• Front and back photo of a Driver's License
• Front and back photo of a State ID
• Front and back photo of a Passport Card
• Photo of the bio page of a Passport

All ID photos must be clear and in color. Expired identification is not accepted.
