# Other Registrar Functions (Burn Tokens, Clawbacks, etc)

NYALA's registrar subsidiary Smart Registry GmbH is an entity regulated by the German financial regulator BaFin. This means that there are several functions that the registrar must possess with regards to the tokenized securities we register. We use the [ERC-3643](https://www.erc3643.org/) (formerly known as T-REX) standard which is the most recognized open-source suite of smart contracts that enables the issuance, management, and transfer of permissioned tokens.

Such functions are not available to external clients. Nonetheless, they are a crucial part of ensuring that securities laws such as the German eWpG are being followed.

The registrar keeps the sole rights to the following token operations. These operations are available to the registrar regardless of which wallet they are contained in, since they happen at the token level – meaning the issuer wallet can control the ERC-3643 tokens wherever they end up.

| Function | Description |
|  --- | --- |
| Clawback tokens | Force transfer tokens from a customer’s wallet back to the Issuer wallet controlled by the registrar. |
| Freeze tokens | Freeze tokens so that they cannot be transferred by anyone but Smart Registry users. Frozen tokens can later be unfrozen, burned or clawed back. |
| Force transfer of tokens | Trigger the remote transfer of specified tokens from any wallet A to wallet B. This function can be triggered even if the tokens are frozen. |
| Burn tokens | Burn specified tokens held in specified wallets. This function can be triggered whether or not the tokens were frozen beforehand. |


These functions are not available for you to trigger via external API endpoints. Should you need us to execute them, however, you can provide us the request with the appropriate justification at any time, and we will take care of it for you. Examples of said requests can include inheritance cases or watchlist flags detected after initial token distribution

For more specific cases where the total supply of tokens must be periodically reduced, for example when redemptions against an underlying should be made possible (which would require burning tokens) we can set up a dedicated endpoint for you after formal contractual agreement.
