Here’s the gap we sit in

There are two kinds of firms serving this market,
but neither one covers all of it.

Most firms do traditional private placements. A smaller number do tokenized ones. Very few do both within a single firm, and that gap is where the work falls through.

01 / THE PROBLEM

Broker-dealers stop at traditional

They can place a conventional Reg D offering well. The moment an issuer wants to issue the security on-chain, the tokenization technology and the blockchain record go to somebody else, and the broker-dealer does not control the technology it is signing off on.

02 / THE PROBLEM

Tokenization platforms only do tokens

They provide the technology to put the instrument on-chain, but the broker-dealer function sits with a third party. And if the offering turns out to be better served in traditional form, tokenizing is the only tool they have.

03 / THE COST

You end up as the integrator

Four vendors, four systems, no shared record, and no single party accountable for the whole. When counsel or an examiner asks a question, the answer has to be assembled from several companies.

04 / WHERE WE SIT

Tokenized or traditional, one broker-dealer

Securities are offered through CPT Capital, LLC, doing business as AstraBlox, a registered broker-dealer for private placements of securities and digital asset securities. AstraBlox also provides the technology issuers use to tokenize and issue their own offerings. Whether your offering is tokenized or traditional depends on what it actually needs, and either way the broker-dealer, the record, and the accountability stay in one place.

Two ways to run the offering

Tokenized or traditional. Same firm, same record.

Not every raise should be on-chain, and we will tell you when yours should not be. The exemption, the instrument, and the investor base drive that decision during the fit review, not a preference on our side.

Digital asset securities

Issued on-chain

The issuer uses AstraBlox technology to issue the security as a token, with eligibility and transfer restrictions enforced at the instrument level. Investors hold their position in a connected wallet, and the on-chain reference is maintained alongside AstraBlox’s own books and records.

  • ERC-3643, ERC-20, ERC-721, ERC-4626
  • Ethereum and Base
  • Transfer rules encoded in the instrument
  • Technology for issuers to tokenize real-world assets
Traditional securities

Issued conventionally

A conventional Reg D private placement with no blockchain component. Same broker-dealer, same onboarding, same verification, same recordkeeping. For many issuers this is the right answer, and it stays on the table.

  • Regulation D private placements
  • Book-entry records, no token required
  • Identical investor verification process
  • Path for the issuer to tokenize later if it fits

AstraBlox does not issue tokens and is not the issuer of any security offered through its platform. Issuers use AstraBlox technology to tokenize their own assets and issue their own tokens, and each issuer remains the issuer of its security. AstraBlox acts as agent for an offering only after its review confirms the required compliance controls are in place.

The platform

Whichever side of the offering you’re on.

One firm, start to finish

Broker-dealer services, the tokenization technology issuers use, and recordkeeping in one place, whether the issuer issues on-chain or in traditional form. Not four vendors and a spreadsheet.

Our differentiator

The token is easy. The record gets examined.

With the right technology, an issuer can deploy a compliant token. The harder question, the one counsel asks before closing and an examiner asks years later, is whether a tamper-evident account exists of what happened, when, and on whose authority. AstraBlox built that recordkeeping layer first, before the parts that demo well. It works the same whether the issuer’s security is issued on-chain or in traditional form.

These records are kept by AstraBlox. Tokens are issued by the issuer using AstraBlox technology; AstraBlox does not issue tokens.

Educational

Which exemption fits your raise?

This is usually the first real decision in a private placement, and it shapes everything that follows. The exemption you rely on determines how you are allowed to reach investors, who is eligible to participate, what you have to verify about them, and what disclosure you owe.

Most private placements run under Regulation D. The two rules below trade one burden for the other: 506(b) keeps the verification light but forbids you from advertising the raise, while 506(c) lets you market openly at the cost of a stricter obligation to confirm every investor is accredited.

The distinction matters more than it first appears. Publicly promoting an offering that was structured to rely on 506(b) can put the exemption itself at risk, and the fix after the fact is expensive. It is worth settling before you write a single piece of outreach.

What we work through with you

  • How you intend to reach investors, and whether any of it counts as general solicitation
  • Whether your investor base is entirely accredited, or includes non-accredited participants
  • What verification your chosen rule requires, and how we handle it in onboarding
  • How the exemption interacts with the token standard you select and its transfer restrictions

506(b), the quiet raise

For offerings sold through existing relationships. No advertising, lighter verification burden.

General solicitationNot permitted
Who can investUnlimited accredited, plus up to 35 non-accredited sophisticated
Verifying statusSelf-certification generally acceptable
Raise limitNo dollar cap
Federal filingForm D, generally within 15 days of first sale
ResaleRestricted securities, transfer limits apply

Other exemptions may fit depending on your raise and your investor base. We work through which one applies during the fit review, alongside your securities counsel. This is general educational information, not legal advice, and not a complete description of any rule.

This page does not advertise any specific offering. Investors are not publicly solicited for any offering structured under Rule 506(b); access is limited to persons with a pre-existing substantive relationship with the firm or the issuer, and is subject to eligibility verification.

Frequently asked

The questions we actually get.

What is AstraBlox?
The private placement business of CPT Capital, LLC, a registered broker-dealer that does business as AstraBlox. It covers the lifecycle of a Regulation D private placement, issued by the issuer either as a digital asset security on-chain or in traditional form: issuer and offering onboarding, investor verification, the tokenization technology issuers use, subscription records, and settlement, together with the recordkeeping required of a broker-dealer.
What is a private placement of digital asset securities?
A securities offering sold under an exemption from registration, where the issuer issues the security as a token on a blockchain rather than recording it solely in a traditional book-entry system. The security remains a security. The same exemption requirements, eligibility rules, and transfer restrictions apply. What changes is how ownership is represented and how restrictions are enforced.
Does AstraBlox issue the tokens?
No. The issuer of each offering uses AstraBlox technology to tokenize its own assets and issue its own tokens, and remains the issuer of the security. AstraBlox provides the technology and proceeds with an offering only after its review confirms the required compliance controls are in place.
Do we have to tokenize the offering?
No. We run Regulation D private placements in traditional form as well, with the same broker-dealer, the same investor onboarding and verification, and the same recordkeeping. Whether tokenization helps depends on the instrument, the investor base, and what you want the security to do after issuance. That is part of the fit review, and if the answer is that your raise does not need to be on-chain, we will say so.
What token standards and networks do you support?
ERC-3643, ERC-20, ERC-721, and ERC-4626, on Ethereum and Base. The standard is selected per offering based on the instrument and its transfer restrictions. Additional networks are on the roadmap, and we’ll tell you plainly if what you need isn’t supported yet.
Who holds custody of the tokens?
You do. The model is strict self-custody. Investors can connect a wallet they already control or create one within the platform, and hold the keys either way. We do not take custody of investor assets.
Who holds the records for an offering?
We do. As the registered broker-dealer, CPT Capital, through AstraBlox, maintains its own trade blotter, ledger logs, and audit trail, written to write-once storage. On-chain references sit alongside those records rather than substituting for them.
How long does an offering take?
It depends on the structure, the instrument, and how prepared the issuer’s materials are. We give you a realistic timeline during the fit review rather than a number on a webpage, and if the timing doesn’t work on our side, we say so on the first call.
Who is the broker-dealer?
CPT Capital, LLC. Securities are offered through CPT Capital, doing business as AstraBlox, a registered broker-dealer and member of FINRA and SIPC. AstraBlox is also the technology platform issuers use to structure, tokenize, and administer their offerings. CPT Capital also does business as AstraBit, which offers non-securities services such as automated trading and portfolio analysis tools. Verify the firm’s registration on FINRA BrokerCheck.

CEX vs DEX: The Real Reason Most Trading Tools Can’t Do Both

CEX vs DEX: The Real Reason Most Trading Tools Can’t Do Both In crypto trading, exchanges fall into two broad categories: centralized (CEXs) and decentralized (DEXs). Each has strengths and trade-offs: custodial vs. non-custodial, liquidity vs. autonomy, user experience vs. transparency. But many traders seek access to both CEX and DEX trading from within a […]
