Why does my crypto sending address keep changing? And why is it different from my deposit address?

Your deposit address is static so people can reliably send you funds.

Your sending address works differently. When you send crypto, transactions are broadcast from a pool of hot wallet addresses rather than a single static address. Outbound transactions are distributed across multiple wallets for security, privacy, and operational resilience.

This is intentional: it keeps outgoing transactions from being linked on-chain to your deposit address, so no one can trace a transaction back to your account.

To verify an outgoing transfer, use the transaction hash from your transaction history instead of a sending address. You may also download the receipt of the transaction as proof.
