Regulation S

Regulation S is the SEC safe harbor for securities offered and sold outside the United States. If the sale is an offshore transaction and the issuer makes no directed selling efforts into the US market, Section 5 registration does not apply to that sale. It sits at 17 CFR 230.901 through 230.905 and it is the offshore leg of most token rounds. It does not make the securities freely tradable, and it is not a route to US buyers.

Reg S is a safe harbor for a transaction, not a status for an asset. Equity of a domestic issuer acquired under Reg S is still a restricted security under Rule 144, and a distribution compliance period of up to a year can sit between the sale and any resale into the United States.

The bottom left cell is the one that costs money. Routing a US buyer through an offshore entity does not make the transaction offshore, because the test asks where the buyer was when the buy order was placed.

The two conditions the safe harbor runs on

An issuer relying on Regulation S has to satisfy two conditions on every sale. The transaction has to be an offshore transaction, which turns on the buyer being outside the United States at the time the buy order is originated, or the offer not being made to a person in the United States. And there can be no directed selling efforts in the United States, meaning no activity that conditions the US market for the securities being offered, such as advertising circulated in the US that references the offering.1

Both conditions describe conduct rather than paperwork, which is where token rounds tend to break them. A public Discord open to anyone, a website with no geographic controls, a founder podcast circuit that reaches a US audience: each is a candidate for directed selling efforts, and none of them appears in a subscription agreement. In our view this is the condition teams treat as a formality and regulators treat as evidence.

Categories and distribution compliance periods

The issuer safe harbor at 17 CFR 230.903 sorts offerings into three categories by how much US flow back risk they carry, and attaches a distribution compliance period to each.2 Category 1 carries minimal or no period, and covers situations such as reporting foreign issuers whose primary trading market is outside the US. Category 2 carries a 40 day period and covers certain debt securities and reporting issuers. Category 3 is the strictest: six months for equity of reporting issuers, and one year for equity of non reporting domestic issuers.

For a typical US incorporated token issuer with no Exchange Act reporting history, that means Category 3 and a one year clock on equity. Build the number into the plan rather than discovering it during a secondary transfer request.

What Regulation S does not do

It does not permanently free securities from US resale restrictions. Equity securities of domestic issuers acquired under Regulation S are restricted securities within the meaning of Rule 144, and resales have to comply with Regulation S, with registration, or with another available exemption.3

It also addresses only the Section 5 registration requirement. The antifraud provisions of the federal securities laws still apply to an offshore offering, which means the disclosure a team gives non US buyers is not a lower standard just because the registration analysis is different.

How token rounds actually use it

The standard structure is a paired offering: the US leg runs under Rule 506(c) of Regulation D with accredited purchasers and documentary verification, and the offshore leg runs under Regulation S. The two are kept operationally distinct, with separate subscription documents, separate purchaser records, and geographic controls on whatever channel the offering is described in.

The failure we see is a single global raise announcement with a Reg S wrapper applied afterwards. Reg S conditions are tested against what happened during the offering, so a safe harbor cannot be retrofitted onto conduct that already happened. If the marketing reached the US market, the analysis starts from that fact.

What we settle before the offshore leg opens

Four answers, written down. Which category the offering falls into, and therefore what the distribution compliance period is. What geographic controls exist on every channel where the offering is described, including social accounts the founders control personally. How buyer location is established and recorded at the time of the buy order. And what restrictions carry into any resale, including transfers that happen on a blockchain rather than through a broker.

Whether a specific offering qualifies for the Regulation S safe harbor is fact specific and jurisdiction specific, and that call belongs to your counsel. This page is reference material for structuring work. It is not legal advice, and it is not a recommendation to buy, sell, or hold any asset.

Common questions

What is Regulation S used for?

It is the SEC safe harbor for securities offered and sold outside the United States. Where a sale is an offshore transaction and the issuer makes no directed selling efforts into the US market, Section 5 registration does not apply to that sale.1 Token rounds typically use it for the non US leg of a raise, alongside a Regulation D exemption covering the US leg.

Can US investors buy in a Reg S offering?

The safe harbor is built around the buyer being outside the United States when the buy order is originated, and around the offer not being made to a person in the United States.1 Routing a US buyer through an offshore vehicle does not by itself make the transaction offshore. US participation is normally handled under a separate Regulation D exemption, not under Regulation S.

How long is the Reg S distribution compliance period?

It depends on the category. Category 1 carries minimal or no period. Category 2 carries 40 days and covers certain debt securities and reporting issuers. Category 3 carries six months for equity of reporting issuers and one year for equity of non reporting domestic issuers.2 A typical US incorporated issuer with no Exchange Act reporting history lands in Category 3.
