### Understanding "Dust" in Cryptocurrency Transactions

If you have noticed small, unexpected amounts of USDT (or other tokens) appearing in your X4T wallet after transactions on any supported network — **BEP20, ERC20, TRC20, Polygon, Arbitrum, Solana** — you are encountering what is commonly known as **"transaction dust"**. Let's demystify it.

###### What Is "Transaction Dust"?

"Transaction dust" refers to **tiny amounts of cryptocurrency** (often less than a cent) that land in your wallet, seemingly out of nowhere. It is different from the residual amount that sometimes stays behind after sending a partial balance — dust originates from external sources you have not directly interacted with.

###### Why "Transaction Dust" Occurs

* **Smart contract outputs**: All EVM-based networks (BSC, Ethereum, Polygon, Arbitrum) and Tron host many smart contracts. Some contracts automatically distribute tiny amounts of tokens as part of a larger programmed operation, leaving dust in your wallet.
* **Token redistribution mechanisms**: Some tokens are designed with built-in policies that distribute a sliver of transaction fees to token holders. These end up as fractional deposits.
* **Refund of excess gas**: Transactions need gas to execute, and sometimes the allocated gas exceeds the amount actually used. The surplus may be converted to a token and returned to you, creating small deposits.
* **Rounding discrepancies**: When trading or transferring tokens, especially across multiple pairs, rounding is necessary due to token divisibility. These can produce tiny overages or shortages.

###### Is "Transaction Dust" a Concern?

Receiving dust is usually **harmless** — it is a byproduct of an active blockchain environment. In rare cases dust can be part of a **"dusting attack"**, where attackers send small amounts of tokens to many wallets to try to track them. This is mainly a **privacy** concern rather than a security one, and it does not impact your funds.

As a best practice, keep an eye on your wallet activity and keep your security measures (2FA, strong password) up to date.

###### Conclusion

Encountering transaction dust — on any of the networks X4T supports — is generally a benign phenomenon and a normal side-effect of how blockchains work. If you ever feel uncertain about an unexpected transaction, our support team is happy to take a look.
