1. Introduction

A Security Token Offering (STO) is a method of raising capital in which digital tokens are issued on a blockchain and represent ownership rights, equity, debt, or other financial instruments. Unlike utility tokens, security tokens are considered securities under most jurisdictions.

STO compliance ensures that offerings adhere to securities laws, protect investors, and mitigate regulatory risk.

2. Regulatory Framework

Securities Laws Application
- Security tokens are treated as securities under acts like:
  - Securities Act of 1933 (U.S.)
  - Securities Exchange Act of 1934 (U.S.)
  - EU Prospectus Regulation (EU 2017/1129)
- Registration or exemption is required before offering to investors.
Key Compliance Areas
- Investor Accreditation: Ensure offerings comply with private vs. public sale regulations.
- Disclosure Obligations: Full and fair disclosure in whitepapers, prospectuses, or offering documents.
- KYC/AML Compliance: Identity verification and anti-money laundering checks.
- Trading Platforms: Listing tokens on regulated exchanges or security token platforms.
- Cross-Border Rules: Compliance with each jurisdiction’s securities regulations.
Registration and Exemptions
- U.S. Examples:
  - Reg D: Private offerings to accredited investors.
  - Reg S: Offshore offerings.
  - Reg A+: Public offerings under a simplified prospectus.

3. Key Compliance Requirements for STOs

Securities Characterization
- Determine if token qualifies as a security using the Howey Test: investment of money, common enterprise, expectation of profits, and reliance on third-party efforts.
Disclosure and Transparency

  - Business model.
  - Risk factors.
  - Token rights (dividends, governance, redemption).
Investor Protection Measures

- Lock-up periods or transfer restrictions to comply with regulations.
Platform and Custody Compliance
- Tokens must be issued on regulated security token exchanges.
- Custodians must comply with fund safeguarding and anti-fraud measures.
Ongoing Reporting
