Any platform that facilitates the buying, selling, or trading of tokenized securities must address the broker-dealer and Alternative Trading System regulatory requirements that apply to intermediaries in the US securities markets. The SEC has been clear that blockchain technology does not create exemptions from these foundational market structure regulations. If a platform matches buyer and seller orders, it must register as an ATS. If a platform effects transactions in securities for the accounts of others, it must register as a broker-dealer. The penalties for operating without registration are severe and include SEC enforcement actions, disgorgement of revenues, and potential criminal liability.
Broker-Dealer Registration Requirements
When Is Registration Required?
Section 15(a) of the Securities Exchange Act of 1934 requires registration as a broker-dealer for any person who effects transactions in securities for the account of others (broker) or buys and sells securities for its own account (dealer), unless an exemption applies.
Activities that trigger broker-dealer registration in the token context include:
- Operating a platform that facilitates the purchase and sale of security tokens
- Soliciting investors or executing orders for security token offerings
- Receiving transaction-based compensation for facilitating security token trades
- Providing investment recommendations in connection with security token transactions
- Holding customer funds or securities in connection with security token transactions
- Acting as a placement agent for security token offerings
Registration Process
Step 1: Form BD Filing File Form BD (Uniform Application for Broker-Dealer Registration) with the SEC through the Central Registration Depository (CRD) system. Form BD includes:
- Firm name and organizational structure
- Principal office and branch office addresses
- Types of business to be conducted
- Control persons and associated persons
- Disciplinary history
- Financial condition
Step 2: FINRA Membership All broker-dealers (with limited exceptions) must become members of FINRA. The FINRA membership application (Form NMA) is extensive and includes:
- Business plan and proposed activities
- Written supervisory procedures
- Compliance policies and procedures
- Financial projections and net capital calculations
- Background checks on all associated persons
- Office inspections
FINRA membership processing time: 6-12 months. Application fee: $7,500 for the initial membership application plus variable assessment fees.
Step 3: State Registration Broker-dealers must register in each state where they conduct business. Most states participate in the CRD system for electronic filing. State registration fees range from $100 to $500 per state.
Step 4: Associated Person Registration All associated persons (employees who effect or are involved in effecting securities transactions) must register with FINRA and pass required qualification examinations:
- Series 7: General Securities Representative (required for most registered representatives)
- Series 63: Uniform Securities Agent State Law Exam (required in most states)
- Series 24: General Securities Principal (required for supervisory personnel)
- Series 79: Investment Banking Representative (for investment banking activities)
- Series 57: Securities Trader (for proprietary trading)
Net Capital Requirements
Broker-dealers must maintain minimum net capital under SEC Rule 15c3-1:
- $5,000: Firms that do not hold customer funds or securities (introducing broker-dealers)
- $25,000: General broker-dealers
- $250,000: Firms carrying customer accounts (clearing broker-dealers)
- $1,000,000: Market makers
For token trading platforms that hold customer assets, the $250,000 minimum typically applies, with additional capital requirements based on the firm’s activities.
Customer Protection Rule
SEC Rule 15c3-3 (Customer Protection Rule) requires broker-dealers that hold customer securities and cash to:
- Maintain a special reserve bank account for the exclusive benefit of customers
- Perform weekly or monthly reserve computations
- Promptly obtain and maintain physical possession or control of customer securities
- Maintain adequate records of all customer positions
For tokenized securities, compliance with Rule 15c3-3 requires:
- Clear custodial arrangements for security tokens
- Wallet infrastructure that satisfies the “possession or control” requirement
- Reserve account funding for customer cash balances
- Accurate reporting of customer token positions
Alternative Trading System Registration
When Is ATS Registration Required?
Rule 3b-16 under the Exchange Act defines an “exchange” as any organization, association, or group of persons that:
- Brings together the orders for securities of multiple buyers and sellers, AND
- Uses established, non-discretionary methods (whether by providing a trading facility or by setting rules) under which such orders interact with each other and the buyers and sellers entering such orders agree to the terms of a trade
Any platform meeting this definition must register as a national securities exchange OR comply with the exemption in Regulation ATS.
For security token platforms, ATS registration is required if the platform:
- Displays or matches buy and sell orders for security tokens
- Operates an order book or matching engine for security tokens
- Provides a bulletin board or marketplace where security token holders can post bids and offers that are matched by the system
Regulation ATS Requirements
An ATS must:
1. Register as a Broker-Dealer: ATSs must be registered broker-dealers and FINRA members before filing Form ATS.
2. File Form ATS: File Form ATS with the SEC at least 20 days before commencing operations. The filing includes:
- Description of the ATS’s operations
- Types of securities traded
- Means of access and participation
- Procedures for entering, displaying, and executing orders
- Fees charged
- Record-keeping procedures
3. Comply with Fair Access Requirements (if threshold is met): If the ATS accounts for 5% or more of the trading volume in any NMS security during four of the preceding six calendar months:
- The ATS must provide fair access to its system
- The ATS must not unreasonably discriminate against participants
4. Maintain Records:
- Records of all subscribers and their orders
- Records of all transactions executed on the ATS
- Daily records of securities traded, including volume and price
- Records retained for a minimum of three years
5. System Capacity and Integrity:
- Maintain adequate system capacity, integrity, and security
- Report material system outages and significant systems changes to the SEC
- Conduct periodic capacity testing
6. Confidentiality:
- Maintain confidentiality of subscriber trading information
- Establish safeguards to protect subscriber information from unauthorized disclosure
Form ATS-N
For ATSs that trade NMS stocks, the SEC requires filing of Form ATS-N, which provides more detailed public disclosure about the ATS’s operations. While most security tokens are not NMS stocks, the SEC has signaled that enhanced transparency for token trading ATSs may be expected.
Special Purpose Broker-Dealer Framework
The SEC staff issued a no-action letter in April 2021 establishing a framework for “special purpose broker-dealers” that custody digital asset securities. Key conditions:
- The broker-dealer’s business is limited to digital asset securities
- The broker-dealer maintains possession or control of digital asset securities and the corresponding private keys
- The broker-dealer conducts and documents a risk assessment of the digital asset securities’ distributed ledger technology
- The broker-dealer establishes policies and procedures to assess a particular distributed ledger technology and the associated digital asset securities
- The broker-dealer complies with Rule 15c3-3 and Rule 17a-5 as applicable
- The broker-dealer provides customers with specific disclosures about the risks of digital asset securities
This framework provides a pathway for token platform operators to establish compliant custody operations within a broker-dealer structure.

- Best execution: Evidence of best execution analysis for customer orders
- Anti-money laundering: BSA/AML program, SAR filing, CIP/KYC procedures
- Supervision: Adequacy of written supervisory procedures, evidence of supervisory review
- Books and records: Completeness and accuracy of transaction records, customer account records, and communications
