# Explanation of Zero Balance after Withdrawing BTC or LTC from Mixin Safe

When withdrawing a portion of your Bitcoin (BTC) or Litecoin (LTC) from Mixin Safe, you might notice your balance temporarily showing zero. This is a regular occurrence caused by the blockchain's "change mechanism," and **does not mean your funds are lost**.



### What is the "Change Mechanism"?

Bitcoin and Litecoin networks use the Unspent Transaction Output (UTXO) model, where each UTXO can only be spent in full and not partially. When making a withdrawal, your wallet uses one or multiple UTXOs as inputs to fulfill the withdrawal amount.

| If the available UTXOs exceed your withdrawal amount, the excess funds are returned to your wallet address as "change."

### Why Does the Balance Show as Zero?

Seeing a zero balance after withdrawal does not indicate a loss of funds. It simply means the original funds from your address have been entirely transferred to a new "change" address. The updated balance will become visible after the transaction is confirmed.

| Since Mixin Safe requires 3 block confirmations for BTC and 12 block confirmations for LTC, your updated balance, including change, typically appears within approximately 30 minutes.
