SAFE vs SAFT vs Token Warrant: Which Web3 Fundraising Instrument, When

Three instruments dominate early Web3 fundraising conversations, and founders routinely treat them as a single menu choice. They are not the same thing. A SAFE gives future equity, a SAFT promises future tokens, and a token warrant is an exercisable right to buy tokens: different assets, different triggers, different securities-law exposure. This article maps the three side by side so you can tell them apart; it is deliberately hedged, because choosing among them is a securities-counsel question. For how they are usually combined into a single raise, see the Web3 fundraising instrument stack.

The three instruments in brief

• A SAFE (Simple Agreement for Future Equity) is the Y Combinator instrument, with the post-money SAFE its 2018 standard. It is not debt and not equity until a trigger (a priced round, M&A or IPO), usually converting with a cap and/or discount.
• A SAFT (Simple Agreement for Future Tokens) promises future tokens at launch. It carries the highest securities risk: in the Kik and Telegram matters the two-stage structure was treated as one transaction on its economic reality, and a SAFT is generally a security during fundraising.
• A token warrant is a right (not an obligation) to buy tokens, actively exercised, which distinguishes it from a SAFT's automatic delivery; it is often paired with a SAFE.
• The three are not interchangeable: they differ in the delivered asset, the trigger, and the securities profile.
• Securities classification is fact-specific, jurisdiction-specific, and tested on economic reality. Nothing here is legal advice; confirm with counsel before issuing anything.

The three instruments at a glance

Each row is a counsel question, not a template default. Do not infer the securities answer from this table.

SAFE: future equity

The SAFE was introduced by Y Combinator in late 2013; the post-money SAFE, YC's 2018 update, is now the industry standard. It is not debt (no interest, no maturity) and not equity until a triggering event, namely a priced equity round, a sale or M&A, or an IPO, usually converting with a valuation cap and/or discount. "Post-money" means ownership is measured after all SAFE money but before the new priced-round money (see post-money SAFE explained). The SAFE is an equity-side instrument; token rights are documented separately.

SAFT: future tokens, and the securities flag

The SAFT promises future tokens at network or protocol launch and was designed to fit US securities law. The Kik and Telegram court matters are decisive against that intent: a two-stage SAFT structure did not exempt the token offering, because the courts treated the private SAFT sale and the later public distribution as effectively a single transaction, judged on economic reality over form. SAFTs are generally treated as securities during fundraising, and the SEC has taken an aggressive stance. There is no blanket answer that a SAFT is or is not a security; it is fact-specific, economic-reality-tested, and a securities-counsel question. This is the highest-risk instrument of the three.

Token warrant: an exercisable right

A token warrant is a right, not an obligation, to buy tokens at a fixed or discounted price in the future, which the holder must actively exercise, unlike a SAFT's automatic delivery. It is often paired with a SAFE, so the investor holds equity (the SAFE) plus token upside (the warrant). US-registered companies are commonly advised to prefer token warrants over vaguer token side letters given regulatory uncertainty. That is common guidance, jurisdiction- and fact-specific, and not legal advice (see token warrant vs token side letter).

How they combine

The instruments are complementary, not substitutes. A frequent stack is a SAFE for equity plus a token warrant or side letter for token upside, the Web3 fundraising instrument stack. Each leg has its own securities and accounting consequence and its own cap-table effect (see token cap-table management), so they must be analysed separately with counsel; there is no universally correct combination.

Practical guidance

1. Map the delivered asset first: equity (SAFE), tokens at launch (SAFT), or an exercisable token right (warrant).
2. Treat the SAFT as the highest-risk instrument, given the Kik and Telegram economic-reality precedent, and do not assume the structure exempts it.
3. Document token rights separately from the SAFE, usually as a token warrant or side letter rather than inside the SAFE.
4. Prefer token warrants over vaguer side letters where counsel advises, especially for US-registered companies, but confirm per jurisdiction.
5. Assess each leg's securities treatment independently; the instrument form does not decide it.
6. Confirm everything with securities counsel; this is fact-specific, jurisdiction-specific, and not legal advice.

Choosing a cap-table tool

A cap-table platform records and models these instruments; it does not determine whether any of them is a security. When you evaluate one for a Web3 raise, confirm that it can represent each instrument's distinct conversion or exercise mechanics, rather than flattening a SAFE, a SAFT and a warrant into one template. Pulley administers token and equity cap tables together for Web3 companies, with custodian integrations, and Carta administers equity cap tables broadly; both model SAFEs, warrants and conversions, but the legal characterisation of each remains a counsel determination.

How Wag3s fits

Wag3s HR records the instrument data behind a Web3 raise, the SAFE conversion terms, the token-warrant exercise terms and the grant schedules, as structured, auditable inputs to cap-table and compensation accounting. Because instrument selection and securities classification are fact- and jurisdiction-specific, those determinations stay with securities counsel; Wag3s supports that work rather than replacing it. See the HR product page.

• SAFT and the securities flag: the SAFT promises future tokens at network launch, but in the Kik and Telegram matters US courts treated the two-stage structure as a single transaction on its economic reality and declined to exempt the token offering. There is no single official authority that settles SAFT classification in general; it is fact-specific and economic-reality-tested, so confirm with securities counsel. See the SAFT securities risk article.
• Token warrant: a right (not an obligation) to buy tokens at a fixed or discounted price, actively exercised, often paired with a SAFE. There is no single statutory standard for token warrants; US-registered companies are commonly advised by counsel to prefer warrants over vaguer side letters.
