What Is a Security Token Offering (STO) and How Does It Work?

What Is a Security Token Offering (STO)?

A Security Token Offering (STO) is a way for companies or projects to raise capital by issuing digital tokens that qualify as securities. During an STO, security tokens are sold or issued. A security token usually represents a financial right, like a share in a company, the right to dividends, the right to interest, profit-sharing, or a claim on an underlying asset like real estate, debt instruments, or a fund.

That’s what makes an STO different from the better-known option in the crypto world: Initial Coin Offerings (ICOs). With an ICO, a utility token is often sold. A utility token gives you access to a certain product or service within a blockchain ecosystem. Think access to a DeFi platform or the right to stake a token. With an STO, it’s specifically about a token that can be economically comparable to traditional securities. Because security tokens can fall under securities laws, STOs are usually more heavily regulated than ICOs.

You can see an STO as a bridge between traditional capital markets and blockchain technology. On one side, it uses familiar financial concepts like ownership, dividends, debt, or revenue rights. On the other side, those rights are recorded and traded digitally through blockchain infrastructure. This can let traditional assets be split into smaller digital units and potentially make them more accessible to a wider group of investors.

Key Takeaways

• A Security Token Offering (STO) is a way for companies or projects to raise capital by issuing digital tokens that can qualify as securities.
• Security tokens usually represent a financial right, like dividends, interest, profit-sharing, or a claim on an underlying asset like real estate or debt instruments.
• STOs differ from ICOs because they’re more focused on regulation, legal structure, and investor rights.
• An STO can make traditional assets more accessible by splitting them into smaller digital pieces using blockchain technology.
• STOs can offer benefits like more transparency, more efficient processes, and new ways to raise funds, but they also come with risks like regulation, limited liquidity, technical issues, and complex valuation.

How Does a Security Token Offering (STO) Work?

A Security Token Offering works by issuing tokens that give you the right to a financial benefit, like dividends or interest. That’s why it’s a fit for a company or project that wants to raise capital. The issuer decides what right the token represents. For example, it could be an equity-like right, a bond-like right, a right to future revenue, or a token tied to an underlying asset like real estate.

A key part of an STO is setting up a legal structure. Since security tokens are often seen as securities, the issuer has to take applicable laws and regulations into account. This can mean a prospectus is required: a detailed document with key information about a new issuance of shares, bonds, or investment products. It can also mean the offering is only available to certain types of investors, or that registration and reporting requirements apply. The exact rules depend on the jurisdiction.

After that, the tokens are technically issued on a blockchain. This is often done through smart contracts: a digital set of rules recorded on a blockchain. A smart contract can include rules about transferability, ownership, voting rights, dividend payouts, or restrictions for certain investors. For security tokens, compliance features play a big role. Think KYC and AML checks, whitelisting approved investors, and limits on trading between parties that don’t meet the requirements.

Investors usually buy the tokens with fiat money or crypto, depending on the platform and the rules. After purchase, the tokens are stored in a Wallet or with a regulated custodian. In some cases, the tokens can later be traded on secondary markets that support digital securities. However, that’s not always a given, because liquidity depends on regulation, market interest, and the availability of regulated trading platforms.

Example: a real estate company wants to raise €10 million for a commercial property. Instead of issuing traditional shares or bonds, the company tokenizes part of the economic rights to the property. Investors buy security tokens and, for example, get the right to a share of the rental income or the proceeds when the property is sold. The ownership and payout rights are linked to the token both administratively and technically.

Examples of Security Token Offerings

Security Token Offerings really started getting attention around 2017 and 2018, when different companies began experimenting with regulated token issuance. The examples below show that STOs aren’t only used by crypto companies, but also in real estate, investment funds, and trading platforms.

The best-known examples of Security Token Offerings are:

• Blockchain Capital in 2017: Blockchain Capital is often mentioned as one of the first well-known examples of a security token offering. The company wanted to raise up to $10 million through the sale of BCAP tokens. These tokens represented an indirect economic interest in a venture capital fund that invested in blockchain companies.
• tZERO in 2018: tZERO, a subsidiary of Overstock.com, raised about $134 million in 2018 through a Security Token Offering. More than 1,000 investors participated in the offering. tZERO focused on infrastructure for trading digital securities and is often seen as an early example of a company trying to combine STOs with a regulated trading platform.
• St. Regis Aspen Resort and Aspen Digital in 2018: In 2018, a portion of the St. Regis Aspen Resort in Colorado was tokenized through Aspen Digital. The offering raised $18 million and gave investors exposure to a real estate project. This example is a solid illustration of how STOs can be used to split up large, illiquid assets like real estate into digital stakes.
• INX Limited in 2020-2021: INX Limited ran one of the best-known regulated security token offerings. The registration statement for the offering was declared effective by the SEC in August 2020, after which INX completed the token offering in 2021. The company raised about $85 million from more than 7,200 retail and institutional investors. The INX token was positioned as a regulated digital security and is an important example of how a token issuance can happen within a formal securities-law framework.

These examples show that STOs can be used in different ways. With Blockchain Capital, it was about access to an investment fund. With tZERO, it was about infrastructure for digital securities. With St. Regis Aspen, it was real estate. And with INX, it was a regulated token issuance for a trading platform. So STOs aren’t one specific type of project, but more of a fundraising method where traditional financial rights are recorded digitally on the blockchain.

Benefits of Security Token Offerings

Security Token Offerings can be appealing for companies and investors who want the benefits of blockchain along with more legal clarity. Compared to many other types of token issuance, STOs put more emphasis on rights, structure, and regulation. The main benefits are accessibility, efficiency, and transparency.

The main benefits of Security Token Offerings are:

• More protection for investors: Because security tokens often fall under securities laws, stricter rules usually apply than with unregulated token sales. Think required disclosures, clear investor rights, and oversight by financial authorities.
• Fractional ownership: STOs make it possible to split large assets into smaller digital pieces. That can let investors participate with smaller amounts in investments that are normally harder to access, like real estate and private equity.
• More efficient processes: Blockchain and smart contracts can automate certain processes, like transferring ownership, recordkeeping, settlement, and parts of compliance. This can make transactions faster and lower operating costs, though it depends on how things are implemented technically and legally.
• More transparency and traceability: Because transactions can be recorded on a blockchain, it can become easier to verify ownership and transfers. That doesn’t mean everything is automatically fully public, but blockchain can help with better recordkeeping and more visibility.
• New funding options for companies: STOs can give businesses an alternative way to raise capital. Companies that want to reach international investors or access new capital markets may especially benefit from this.

Risks of Security Token Offerings

Even with these benefits, Security Token Offerings also come with risks. STOs are often pitched as an innovative way to raise money, but that doesn’t mean they’re automatically simple, safe, or liquid. The biggest risks are legal, technical, and financial.

The main risks of Security Token Offerings are:

• Regulatory risk: Because security tokens can be treated as securities, issuers and platforms have to comply with strict laws and regulations. If an STO is set up incorrectly from a legal standpoint, it can lead to fines, restrictions, or other legal issues.
• Limited liquidity: Even though tokenization is often seen as a way to make assets easier to trade, in practice there isn’t always enough trading activity. Without an active secondary market, it can be hard to sell security tokens quickly or at a good price.
• Complex valuation: The value of a security token depends on multiple factors, like the underlying asset, the issuer’s financial health, market conditions, and demand for the token. That can make it hard to determine a fair price.
• Technical risks: STOs depend on blockchain technology, smart contracts, Wallets, and trading platforms. Bugs in smart contracts, security issues, or operational outages can affect the safety and usability of the tokens.
• Counterparty risk: The value of a security token often depends on the party behind the issuance or the management of the underlying asset. If that party performs poorly or doesn’t meet its obligations, it can negatively impact investors.
• Overhyped expectations: Tokenization can make processes more efficient, but it doesn’t automatically fix every issue in traditional financial markets. Things like legal enforceability, investor protection, oversight, and liquidity still matter with STOs too.

So Security Token Offerings are mainly interesting as a regulated form of tokenization, where digital innovation is combined with traditional financial rights. For investors, it’s important to look not only at the upside, but also at the legal structure, the issuer’s quality, and the risks of the underlying asset.

Final thoughts

Security Token Offerings show how traditional financial markets and blockchain technology can move closer together. By recording financial rights digitally on a blockchain, companies can raise capital in a new way, and investors can get access to assets that are normally harder to reach.

At the same time, STOs aren’t a simple or risk-free solution. Since security tokens often fall under securities laws, legal structure, oversight, and regulatory compliance play a major role. Liquidity, valuation, technical security, and the issuer’s reliability also remain key things to pay attention to.

That’s why an STO can be most interesting when the issuance is well-regulated, transparent, and carefully set up. For investors, it’s important not just to focus on the promise of tokenization, but also on the rights the token gives, the quality of the underlying asset, and the risks that come with the investment.
