What Are Security Tokens

Security tokens are digital assets issued on a blockchain that represent ownership interests in traditional securities — equity, debt, revenue participation rights, fund shares, real estate interests, or other investment instruments. Unlike utility tokens that provide access to a platform or service, security tokens are explicitly designed as investment vehicles and are subject to the full weight of securities regulation in every jurisdiction where they are offered or traded.

The security token market has grown significantly since the first compliant offerings in 2018-2019. By 2025, the total market capitalization of tokenized securities exceeded $12 billion, with tokenized US Treasury products, real estate tokens, and private equity tokens representing the largest categories. Major financial institutions including Goldman Sachs, JPMorgan, and BlackRock have launched tokenized asset products, validating the market’s transition from experimental to institutional.

For compliance officers and legal counsel, security tokens present a fundamental question: how do existing securities regulation frameworks apply to assets that exist natively on a blockchain, can be transferred peer-to-peer, and operate on infrastructure that was not contemplated when securities laws were written? The answer, at least in the US, is straightforward in principle — securities laws apply based on the economic substance of the instrument, not its technological form — but complex in implementation.

The Howey Test and Token Classification

The threshold compliance question for any token is whether it constitutes a security. In the United States, the primary framework is the Supreme Court’s 1946 decision in SEC v. W.J. Howey Co., which established that an “investment contract” exists when there is:

1. An investment of money
2. In a common enterprise
3. With a reasonable expectation of profits
4. Derived from the efforts of others

The SEC’s Division of Corporation Finance published its “Framework for ‘Investment Contract’ Analysis of Digital Assets” in April 2019, applying the Howey factors specifically to digital assets. Key considerations include whether purchasers have a reasonable expectation of profit, whether a centralized team is responsible for developing the project, whether there is a secondary market for the token, and whether the token’s functionality is fully developed at the time of sale.

Tokens That Are Almost Certainly Securities

• Tokens representing equity in a company
• Tokens paying dividends or revenue shares
• Tokens marketed as investment opportunities
• Tokens sold at a discount with lock-up periods suggesting investment intent
• Fund tokens representing shares in investment vehicles
• Real estate tokens representing fractional ownership interests

Gray Area Tokens

• Tokens with both utility and investment characteristics
• Governance tokens for DeFi protocols
• Staking tokens with yield components
• NFTs with royalty or revenue-sharing features

For compliance purposes, the conservative approach is to treat any token with investment characteristics as a security unless a definitive legal analysis concludes otherwise.

SEC Registration and Exemption Frameworks

If a token is a security, the issuer must either register the offering with the SEC under Section 5 of the Securities Act of 1933 or qualify for an exemption from registration. Full SEC registration is rarely used for token offerings due to the expense, timeline, and ongoing reporting obligations. Instead, virtually all security token offerings rely on one of the available exemptions.

Choosing the Right Exemption

Regulation D Offerings

Regulation D is the most commonly used exemption for security token offerings. It provides two primary safe harbors:

Rule 506(b)

Rule 506(b) permits the issuer to raise unlimited capital from an unlimited number of accredited investors and up to 35 non-accredited but sophisticated investors. General solicitation and general advertising are prohibited, meaning the issuer cannot publicly market the offering. The prohibition on general solicitation requires that issuers have a pre-existing substantive relationship with potential investors before presenting the offering.

Compliance Requirements:

• File Form D with the SEC within 15 calendar days of the first sale
• Verify that non-accredited investors meet the sophistication standard
• Provide non-accredited investors with disclosure documents comparable to registered offerings
• Comply with state blue sky requirements (though Rule 506 preempts state registration requirements, notice filings may still be required)
• Implement transfer restrictions — Rule 506 securities are “restricted securities” subject to holding period requirements under Rule 144

Rule 506(c)

Rule 506(c) permits general solicitation and advertising, making it suitable for publicly marketed token offerings. However, all purchasers must be accredited investors, and the issuer must take “reasonable steps” to verify accredited status. Acceptable verification methods include reviewing tax returns, bank/brokerage statements, or obtaining written confirmation from a registered broker-dealer, attorney, CPA, or investment adviser.

Compliance Requirements:

• All 506(b) requirements, plus
• Implement and document accredited investor verification procedures
• Maintain records of verification methods used for each investor
• Consider using third-party accreditation verification services

Transfer Restrictions for Reg D Tokens

Securities sold under Regulation D are restricted securities. For token issuers, this means implementing transfer restrictions in the token’s smart contract. Typical implementations include whitelisting — only allowing transfers to wallet addresses that have been verified as belonging to qualified investors — and holding period enforcement through smart contract logic that prevents transfers during the applicable holding period.

Regulation A+ Offerings

Regulation A+ offers two tiers of exempt offerings that allow both accredited and non-accredited investors to participate, making it the most accessible framework for broad-based security token distribution.

Tier 1

• Maximum raise: $20 million in a 12-month period
• No limit on individual investment amounts
• Requires SEC qualification of an offering circular
• No ongoing SEC reporting obligations
• State blue sky compliance required (not preempted)

Tier 2

• Maximum raise: $75 million in a 12-month period
• Non-accredited investors limited to investing the greater of 10% of annual income or 10% of net worth
• Requires SEC qualification of an offering circular
• Ongoing reporting: annual reports (Form 1-K), semi-annual reports (Form 1-SA), current reports (Form 1-U)
• State blue sky compliance preempted

Compliance Considerations for Reg A+ Token Offerings:

• The offering circular must be qualified by the SEC before sales begin, typically taking 3-6 months
• Audited financial statements are required for Tier 2
• The offering circular must disclose all material information about the issuer, the tokens, and the risks
• Ongoing reporting obligations for Tier 2 create a continuous compliance burden
• Token transfer mechanisms must ensure compliance with investment limits for non-accredited investors in Tier 2

Regulation S and Cross-Border Compliance

Regulation S provides a safe harbor for securities offerings made outside the United States to non-US persons. For token issuers, Reg S is typically used in combination with a Reg D offering to the US market, allowing the issuer to raise capital from both US and non-US investors under a dual-exemption structure.

Key Compliance Requirements

Distribution Compliance Period. For equity securities of non-reporting issuers, the distribution compliance period is one year from the later of the closing date or the date the securities were first offered to persons other than distributors. During this period, additional restrictions apply to resales.

Offering Restrictions. No directed selling efforts in the United States during the distribution compliance period. Token marketing materials must not be targeted at US persons.

Transactional Restrictions. During the distribution compliance period, offers and sales must be made in offshore transactions, and no offers or sales may be made to US persons.

Smart Contract Implementation. Token smart contracts must include geographic restrictions that prevent transfers to wallets associated with US persons during the distribution compliance period. This requires integration with KYC data to maintain a real-time registry of investor jurisdictions.

Regulation CF Compliance

Regulation CF (crowdfunding) permits offerings of up to $5 million in a 12-month period through a registered funding portal or registered broker-dealer. While the relatively low cap limits its use for larger token offerings, Reg CF is attractive for early-stage projects seeking community-based fundraising.

Investment Limits. Individual investment amounts are capped based on the investor’s annual income and net worth. If either annual income or net worth is less than $124,000, the limit is the greater of $2,500 or 5% of the lesser of annual income or net worth. If both are at least $124,000, the limit is 10% of the lesser, with a maximum of $124,000.

Platform Requirement. All Reg CF offerings must be conducted through a registered funding portal or broker-dealer, which serves as a compliance intermediary.

Disclosure. Issuers must file Form C with the SEC, disclosing the terms of the offering, use of proceeds, business description, financial statements, and risk factors.

Broker-Dealer and ATS Requirements

The distribution and secondary trading of security tokens involves broker-dealer regulation. Any entity that effects transactions in securities for the account of others, or that buys and sells securities for its own account as part of a regular business, must register as a broker-dealer with the SEC and become a member of FINRA.

Token Distribution

Security token offerings that involve third parties soliciting investors, handling investor funds, or facilitating the sale of tokens generally require broker-dealer involvement. Token issuers that distribute their own securities may rely on the “issuer exemption” from broker-dealer registration, but this exemption is narrow and does not cover compensation-based solicitation or transaction-based compensation to finders.

Alternative Trading Systems

Platforms that facilitate secondary trading of security tokens must register as broker-dealers and may need to register as Alternative Trading Systems (ATSs) under Regulation ATS. ATS registration requires compliance with reporting, record-keeping, and operational requirements, and ATSs that exceed certain volume thresholds face additional obligations including fair access requirements.

Several ATS-registered platforms now support security token trading, including tZERO, Securitize Markets, and INX Securities. These platforms provide the regulated infrastructure for compliant secondary market trading of tokenized securities.

Transfer Agent Obligations

Transfer agents maintain the official record of securities ownership, process transfers, and handle investor communications. For security tokens, the transfer agent function raises unique questions about the relationship between blockchain-recorded ownership and the official ownership register.

The SEC has taken the position that blockchain-based records do not automatically satisfy transfer agent requirements. Token issuers must either engage a registered transfer agent or register as a transfer agent themselves if they maintain the official ownership records.

Several compliance-focused token platforms (Securitize, Polymath/Polymesh) have obtained transfer agent registration to provide an integrated issuance, compliance, and registry solution.

Investor Qualification and Accreditation

Accredited Investor Definition

Under SEC Rule 501(a), an accredited investor includes individuals with net worth exceeding $1 million (excluding primary residence) or annual income exceeding $200,000 ($300,000 jointly with spouse) in each of the two most recent years with a reasonable expectation of the same in the current year. The definition also includes certain entities, professionals holding qualifying certifications, and knowledgeable employees of private funds.

Verification Methods

For Rule 506(c) offerings requiring verification, acceptable methods include reviewing the investor’s IRS forms (W-2, 1099, K-1) for income verification, obtaining written confirmation from a licensed professional (CPA, attorney, registered investment adviser, or registered broker-dealer), or reviewing bank and brokerage statements for net worth verification.

Third-party verification services have emerged to streamline this process, providing digital accreditation verification that integrates with token issuance platforms.

Secondary Market Compliance

Secondary trading of security tokens must comply with securities transfer restrictions, ATS and broker-dealer requirements, and applicable state regulations. Key compliance considerations include:

Transfer Restrictions. Smart contracts must enforce applicable transfer restrictions, including holding periods for restricted securities, geographic restrictions, and investor qualification requirements. Programmable compliance — encoding regulatory rules into smart contract logic — is a key advantage of security tokens over traditional securities.

ATS or Exchange Trading. Secondary trading must occur on registered platforms. Peer-to-peer transfers of security tokens outside registered platforms may violate broker-dealer requirements if they involve solicitation or compensation.

Reporting. Issuers of Reg A+ Tier 2 securities and other reporting issuers must provide ongoing financial disclosures that support informed secondary market trading.

Ongoing Reporting Obligations

Security token issuers face ongoing compliance obligations that extend well beyond the initial offering:

• Reg A+ Tier 2: Annual reports (Form 1-K), semi-annual reports (Form 1-SA), current event reports (Form 1-U)
• Reg CF: Annual reports to investors and the SEC
• State Requirements: Ongoing state notice filings and compliance
• Tax Reporting: Form 1099-DIV for dividend distributions, Form 1099-B for secondary market transactions (through broker-dealers)
• Transfer Restriction Maintenance: Ongoing management of smart contract transfer restrictions and investor registries

International Securities Token Frameworks

European Union

Under MiCA, tokens that qualify as financial instruments (securities) are excluded from MiCA’s scope and remain subject to MiFID II and the Prospectus Regulation. The EU’s DLT Pilot Regime Regulation provides a sandbox framework for trading and settlement of tokenized financial instruments on distributed ledger technology.

Singapore

The Securities and Futures Act applies to digital tokens that constitute securities or units in a collective investment scheme. The MAS has provided guidance on the application of securities laws to digital token offerings.

Switzerland

FINMA’s guidelines classify tokens into payment tokens, utility tokens, and asset tokens, with asset tokens subject to securities regulation under the Financial Market Infrastructure Act. Switzerland’s DLT Act, effective August 2021, provides a comprehensive legal framework for tokenized securities.

United Kingdom

The FCA regulates security tokens under existing securities regulation, including the Financial Services and Markets Act 2000. Token issuers must comply with prospectus requirements and other securities obligations.
