Most tokenized securities cannot be freely resold right away. Resale restrictions depend on the exemption you used: Reg D securities are "restricted" with roughly a one-year holding period, Reg CF has a one-year restriction with limited exceptions, Reg S has a distribution-compliance period, and Reg A+ securities are generally freely tradable. On top of these legal limits, you may add a contractual lock-up. For tokens, these rules are typically enforced in the smart contract itself.

Why resale is restricted

Securities sold under exemptions are "restricted" because they were not registered for public trading. The restriction protects the market: it prevents exemption-sold securities from immediately flooding into public hands as if they had been through full registration.

So the freedom to skip registration comes paired with limits on resale. As the issuer, you inherit the duty to enforce them.

The holding periods by exemption

The periods differ. Reg D securities are restricted, generally requiring about a one-year hold before resale under Rule 144. Reg CF securities carry a one-year restriction with narrow exceptions. Reg S imposes a distribution-compliance period - roughly 40 days to a year by category - during which no resale to US persons. Reg A+ securities are usually not restricted, so they can trade freely once issued.

This is a major reason Reg A+ appeals to issuers who want secondary liquidity for holders.

Two details sharpen the Reg D case specifically. The Rule 144 holding period is six months only for securities of a company that files Exchange Act reports; a typical RWA sold through a private, non-reporting SPV falls into the one-year bucket. And clearing the holding period is not the end of it - resale of a restricted security to a US person usually still needs its own exemption, and if the seller is an affiliate of the issuer, Rule 144 adds volume limits and a continued-information condition on top. "The year is up" is necessary, not sufficient.

Reg S is not one period but three categories, graded by how much US-market nexus the issuer has: the distribution-compliance period runs from no restriction (Category 1) up to 40 days for debt and a full year for the equity of a US domestic issuer (Category 3), which is where most US-sponsor RWAs land.

How tokens enforce them

For a traditional security, resale limits are tracked by a transfer agent and legends on certificates. For a token, the smart contract enforces them directly: a transfer restriction coded into the token blocks transfers that would violate the holding period or send tokens to an ineligible wallet.

This is a genuine advantage - compliance is automatic and hard to breach - but it means the rules must be coded correctly from the start. A mistake here is a compliance mistake, not just a bug.

Legal limits vs contractual lock-ups

Beyond the legal minimum, you can impose a contractual lock-up - a period you require holders to stay invested, common in development deals. This is your choice as issuer, layered on top of the exemption's resale rule.

Be clear with investors about both: the legal restriction and any lock-up you add. Their secondary-market options depend on both, and surprises here damage trust. One more nuance for affiliates - insiders and large holders - Rule 144 adds volume limits even after the holding period, capping sales in any three months at roughly 1% of the outstanding supply, which a compliant token can encode directly. Your investors see the same rules from their side in resale rules for investors.
