# Tether burn and unfreeze

Tether blacklists and unblacklists wallets. Tether can also burn blacklisted funds. Here is an example that shows all of those features.

`0x55Df4Ecd9066C417103F59d3eCc9B309Dedfd131` was blacklisted and unblacklisted. There are several ways to see this.

1. The information is visible in the [wallet label](https://dashargos.chainargos.com/dashboards/88?Address=%250x55Df4Ecd9066C417103F59d3eCc9B309Dedfd131%25)
2. You can search using the [usual tools](/documentation/research/empirical-research/blacklist/monitoring.md)
3. Building any query using blacklisting-related tags [like some of these](https://docs.chainargos.com/documentation/info/explore/ethereum/to-wallet)

Most likely you are running a report of recently-blacklisted addresses. Here is a dashboard [for this address](https://dashargos.chainargos.com/dashboards/57?To+or+From+Address=0x55Df4Ecd9066C417103F59d3eCc9B309Dedfd131\&Symbol=). You will notice an outflow to `0x0.000` or `NULL` before the blacklisting was lifted.

We can drill in to this as normal and get the transaction hash: `0x0da9684a6bc67db25050a7006e35f576a95b01832a0e8f09c2cd25a9651f139b`.

This is not a normal ERC-20 transfer. It comes from a call to `DestroyedBlackFunds`. You can see this on etherscan [here](https://etherscan.io/tx/0x0da9684a6bc67db25050a7006e35f576a95b01832a0e8f09c2cd25a9651f139b#eventlog). DashArgos simplifies this for you by showing the flow as a transfer. Notice the flow does not appear in many other sources -- the balance jumps without a corresponding outflow.

These flows are [fairly common](https://dashargos.chainargos.com/looks/770).

## Unblacklisting

In the case of `0x55Df4Ecd9066C417103F59d3eCc9B309Dedfd131` we see the following chain of events:

1. Blacklisted 2022-10-18
2. $863k of funds burned by Tether 2024-03-08
3. Unblacklisted 2024-03-08

This left a balance of about $390k in the wallet. Not everything was burned.

This sure looks like Tether recovered some of the balance for law enforcement and then let the address go with the rest.
