Bitcoin dust refers to UTXOs with tiny values that are so small that they are economically unspendable. That is, it costs more (in transaction fees) to spend than the value of the UTXOs. It’s possible to end up with dust in your wallet due to poor UTXO management. It’s also possible to receive dust deposits that you did not request. This is because you can’t stop someone from sending funds to a valid bitcoin address and every bitcoin address that has ever received funds is publicly viewable on the blockchain.
