The Two Tokenized Stock Models and When to Build Each
The architecture of a tokenized equity platform depends entirely on which model you are building. These are not interchangeable, and the wrong choice creates compliance exposure or liquidity problems that are expensive to fix post-launch.
| Equity-Backed Spot Tokens | Synthetic / Oracle-Priced Tokens | |
|---|---|---|
| Underlying asset | Real shares held in regulated custody | No underlying share, price tracked via oracle |
| Investor rights | Voting rights, dividends, legal claim on shares | Economic exposure only, no shareholder rights |
| Regulatory classification | Security, subject to SEC / FINRA oversight | Varies, often derivative or complex financial product |
| Custody requirement | Registered custodian or broker-dealer required | No custody needed, oracle and smart contract sufficient |
| DeFi composability | Limited by compliance controls | High, can be used in lending, borrowing, perpetuals |
| Who builds this | Broker-dealers, fintechs, regulated issuers | DeFi protocols, crypto-native platforms |
| Standard used | ERC-3643, ERC-1400 | ERC-20 with oracle integration |
Underlying asset
Equity-backed: Real shares held in regulated custody
Synthetic: No underlying share, price tracked via oracle
Investor rights
Equity-backed: Voting rights, dividends, legal claim on shares
Synthetic: Economic exposure only, no shareholder rights
Regulatory classification
Equity-backed: Security, subject to SEC / FINRA oversight
Synthetic: Varies, often derivative or complex financial product
Custody requirement
Equity-backed: Registered custodian or broker-dealer required
Synthetic: No custody needed, oracle and smart contract sufficient
DeFi composability
Equity-backed: Limited by compliance controls
Synthetic: High, can be used in lending, borrowing, perpetuals
Who builds this
Equity-backed: Broker-dealers, fintechs, regulated issuers
Synthetic: DeFi protocols, crypto-native platforms
Standard used
Equity-backed: ERC-3643, ERC-1400
Synthetic: ERC-20 with oracle integration
Most regulated financial companies need the equity-backed spot token model. DeFi-native projects typically build the synthetic model for permissionless access to equity price exposure. SpaceDev builds both, with the architecture driven by your regulatory environment and target user base.
Key Compliance Infrastructure for Tokenized Stock Platforms
Transfer Restrictions Enforced at the Contract Level
ERC-3643 (T-REX) enforces accreditation checks, jurisdictional restrictions, and investor allowlists directly in the smart contract. A transfer that does not meet the compliance criteria does not execute, regardless of who initiates it. This is the technical standard used by Securitize and Tokeny, and the platforms backing BlackRock and KKR tokenized funds.
On-Chain KYC/AML and Investor Accreditation
Every investor who holds tokenized equity must be verified before receiving a transfer. We integrate KYC/AML providers including Sumsub, Jumio, and Onfido into the onboarding flow, with accreditation status mapped to the on-chain identity layer.
Forced Transfer and Token Recovery Mechanisms
Regulated equity platforms require the ability to force transfer or freeze tokens in response to court orders, regulatory action, or investor offboarding. ERC-3643 includes these mechanisms natively.
Proof of Reserves and Custody Verification
For equity-backed token platforms, every token minted must correspond to a real share held in custody. We integrate Chainlink Proof of Reserves to provide on-chain verification of the custody backing ratio.

How We Approach Stock Tokenization Development Projects
-
Token Model and Compliance Scoping
We define the token model (equity-backed vs. synthetic), the regulatory framework your platform operates within, the custody structure, and the KYC/AML requirements before any architecture decisions are made. Our Product Discovery service covers this scoping phase as a standalone engagement.
-
Smart Contract Development
We build the issuance contracts, transfer restriction logic, corporate actions mechanisms, and cap table registry using ERC-3643 or ERC-1400 depending on your requirements.
-
Compliance Infrastructure and KYC Integration
We build the identity layer, investor onboarding flows, and on-chain allowlist management that your compliance team will operate day-to-day, plus admin tooling for manual overrides and regulatory reporting exports.
-
Custody and Oracle Integration
We integrate the custody infrastructure appropriate to your model, including Proof of Reserves verification if you are building an equity-backed platform.
-
Investor Portal, Issuer Console, and Secondary Market
We build the product layer: investor dashboards, issuer consoles for cap table management and corporate actions, and the integrations required for your tokens to be tradeable on your target venues.
-
Security Review and Pre-Launch Audit
Every tokenized equity platform goes through structured security review before launch. Given the regulated nature of these systems, independent smart contract auditing through BlockAudit is strongly recommended.
