What Is the Difference Between Tokenized Stocks and Synthetic Stock Tokens?

The fundamental difference between tokenized stocks and synthetic stock tokens is whether real shares stand behind them. Tokenized stocks are issued directly by a company, or issued 1:1 by a custodian that holds real shares; synthetic stock tokens track the share price using only contracts and collateral, without buying a single share. The former represent a claim on the stock; the latter are simply a contract betting on its price.

How Do Their Underlying Assets Differ?

The underlying asset of a tokenized stock is real shares. With native issuance, the token is the share on the shareholder register; with custody backing, the issuer holds an equal number of shares with a broker or custodian, and must hold one more share for every token it issues.

The underlying asset of a synthetic stock token is collateral, usually crypto assets or stablecoins. It uses an oracle to obtain the share price from external sources, then relies on collateral and liquidation mechanisms to keep the token’s value in line with the share price. This corresponds to the price-tracking category among RWA tokenization models.

How Do Holders’ Rights Differ?

Holders of tokenized stocks are shareholders, or have a claim on the shares held by the issuer. They can usually receive dividends under the terms and, where the issuer allows, redeem tokens for shares or cash.

Holders of synthetic stock tokens only have gains or losses from price movements, with no shareholder rights, and cannot exchange tokens for real shares. Some products convert dividends into token price adjustments, but that is just a contract rule, not a dividend paid by the company.

What Happens If the Issuer or Protocol Fails?

For custody-backed tokens, risk is concentrated in the issuer and custodian: as long as the shares are genuinely held in segregation, holders still have a chance to recover the corresponding assets if the issuer runs into trouble; if they are not segregated or not fully held, losses are hard to avoid.

For synthetic tokens, the risk lies in the protocol itself: oracle pricing errors, collateral crashes that leave liquidations short, or contract exploits can all push the token price away from the share price, and holders have no underlying shares to claim.

How Can You Tell Which One You Bought?

Start with the product documents: does the issuer state that it holds real shares, which institution provides custody, and are there regular proof-of-holdings reports or audits? Then look at the on-chain contract: regulated tokenized stocks usually include identity and compliance checks, for example by using a permissioned standard such as ERC-3643; synthetic tokens are often freely transferable, with collateral and oracle modules visible in the contract.

Finally, check redemption: if the token can be exchanged 1:1 for real shares or equivalent cash, it is a tokenized stock; if it can only be sold on the secondary market, it is likely a synthetic token.

Conclusion

Tokenized stocks are backed by real shares, with risk in the issuer and custody; synthetic stock tokens are backed by collateral and contracts, with risk in the protocol. Their names and prices may be identical, so be sure which one you are buying before you buy. Safeheron’s MPC Wallet-as-a-Service provides businesses with MPC key management and a policy engine.
