S.A.F.E vs S.A.F.T

The primary difference between a SAFE. and a SAFT. is that a **SAFE (Simple Agreement for Future Equity) grants investors the right to future shares of company stock, whereas a SAFT (Simple Agreement for Future Tokens) provides the right to future digital tokens or coins upon a network launch.** While both are popular financial instruments in the startup ecosystem, they cater to fundamentally different asset classes and regulatory frameworks. Founders must choose between these instruments based on whether their valuation is tied to corporate ownership or the utility and scarcity of a decentralized protocol’s native digital asset.

What is a SAFE (Simple Agreement for Future Equity)?

A SAFE (Simple Agreement for Future Equity, a legal instrument created by the startup accelerator Y Combinator in 2013) is a contract between an investor and a startup that provides the investor with the right to receive equity in the company at a later date, typically triggered by a specific event such as a priced round of venture capital. Unlike traditional convertible notes, a SAFE is not debt; it does not accrue interest, and it does not have a maturity date. This simplifies the negotiation process between founders and early-stage investors by deferring the valuation of the company until a more substantial funding round occurs.

The core components of a SAFE include the valuation cap (the maximum valuation at which an investor’s investment converts into equity) and the discount rate (a percentage reduction from the price per share paid by investors in the subsequent funding round). Because a SAFE represents a claim on the company’s capital stock, it is governed by traditional securities laws. Founders often prefer SAFEs because they are shorter than conventional debt agreements, usually spanning only five to six pages, which significantly reduces legal overhead costs during the pre-seed and seed stages of a business.

What is a SAFT (Simple Agreement for Future Tokens)?

A SAFT (Simple Agreement for Future Tokens, a framework introduced by Protocol Labs and Cooley LLP in 2017) is an investment contract used by blockchain and decentralized finance (DeFi) projects to sell rights to future digital assets. Investors provide upfront capital to the project in exchange for the promise of receiving a specific number of tokens once the project’s network or platform becomes operational. This framework was specifically designed to help blockchain startups navigate the complexities of the Howey Test (a legal standard used by the SEC to determine if a transaction qualifies as an investment contract).

Under the SAFT model, the agreement itself is treated as a security, meaning it is typically offered only to accredited investors under exemptions like Regulation D. However, the goal of the SAFT is that the tokens delivered at the end of the contract will be functional “utility tokens” rather than securities, though the SEC (Securities and Exchange Commission) continues to scrutinize this distinction. SAFTs are essential for projects where the primary value driver is the usage of a protocol rather than the ownership of the corporation developing that protocol.

Why is a SAFT used instead of a SAFE for Web3 startups?

Web3 startups utilize the SAFT instead of a SAFE when the ultimate value proposition of the venture is tied to a decentralized ecosystem where tokens serve as the medium of exchange, governance, or utility. In many decentralized autonomous organizations (DAOs) or Layer 1 blockchain protocols, the equity in the founding corporate entity may eventually become secondary to the value of the tokens circulating on the network. Using a SAFT ensures that the investor’s interests are aligned with the success of the protocol’s tokenomics rather than just the company’s balance sheet.

A significant distinction lies in the liquidity timeline. In a traditional SAFE ecosystem, investors often wait 5 to 10 years for an “exit” event like an IPO (Initial Public Offering) or an acquisition to see a return. Conversely, SAFT investors often seek liquidity much sooner through the listing of tokens on secondary digital asset exchanges once the Mainnet (the primary functional blockchain network) launches. This accelerated liquidity profile is a defining characteristic of the SAFT, though it comes with high regulatory risks regarding the classification of the tokens upon delivery.

How do the legal risks of a SAFT compare to a SAFE?

The legal risks of a SAFE are relatively low because they follow well-established corporate law and are widely accepted by the SEC and venture capital firms as standard equity-linked instruments. The primary risk with a SAFE is “dilution,” where a founder issues too many SAFEs at low valuation caps, resulting in the founder losing a significant percentage of ownership once the SAFEs convert into shares during a Series A round.

In contrast, the legal risks of a SAFT are considerably higher due to the evolving regulatory stance on digital assets. If the SEC determines that the tokens delivered via a SAFT are actually “unregistered securities” rather than utility tokens, the project could face significant fines, rescission offers, and forced registration. Research from various legal clinics suggests that since 2018, the SEC has increased its enforcement actions against token-based fundraisers, emphasizing that the “utility” of a token at launch does not automatically exempt it from being classified as a security if the investment was made with an expectation of profit derived from the efforts of others.

Which instrument is better for early-stage fundraising?

Choosing between a SAFE and a SAFT depends entirely on the long-term monetization strategy of the business. If the company is building a traditional software-as-a-service (SaaS) platform where revenue and dividends are the primary drivers, a SAFE is the optimal choice. It is a proven, “safe” instrument that 99% of venture capital investors understand and accept without friction.

However, if the business is building a decentralized protocol like Ethereum or Uniswap, where the token is the product, a SAFT is often the only way to satisfy investors who want exposure to the token’s upside. It is important to note that some hybrid models use a “Side Letter” alongside a SAFE to give investors both equity and a “pro-rata” right to future tokens. This hybrid approach ensures that if the company pivots from a centralized service to a decentralized protocol, the early investors are protected across both asset classes.

Frequently Asked Questions

Can a SAFE be used to purchase tokens?
No, a standard SAFE (Simple Agreement for Future Equity) is strictly designed for the acquisition of company stock and does not naturally grant rights to digital assets or tokens. If a founder wishes to grant token rights within an equity framework, they must use a “Token Warrant” or a specific “Token Side Letter” that amends the SAFE to include future token distributions.

Is a SAFT considered a security under US law?
Yes, the SAFT (Simple Agreement for Future Tokens) itself is almost universally considered a security because it involves an investment of money in a common enterprise with an expectation of profits. For this reason, SAFTs are typically issued under Regulation D Section 506(c), which limits the offering to “accredited investors” who meet specific income or net worth or professional criteria.

What happens to a SAFE if the company is acquired?
If a company is acquired before a SAFE converts into equity, the SAFE holder usually has the choice between receiving a cash payment equal to their original purchase amount or converting the SAFE into a number of shares of common stock calculated based on the “Liquidity Price.” This ensures that the SAFE investor receives a return comparable to an early shareholder in the event of a premature exit.

Are SAFTs still used in 2026?
While the popularity of SAFTs peaked in 2017-2018, they remain a standard tool for Web3 fundraising in 2026, albeit with more sophisticated legal guardrails. Many modern projects now use a “SAFE + Token Side Letter” approach to provide investors with a cleaner path to equity while still promising token allocations, providing a hedge against the regulatory uncertainty of pure-play SAFTs.
