Bridging vs moving funds through an exchange

Deposit USDC on one chain, withdraw it on another: for anyone who already has a funded, verified exchange account, this is a legitimate way to move between chains, and for large amounts it is often the cheapest.

What the exchange route costs you

• Custody. The exchange holds your funds between the deposit and the withdrawal.
• Identity. Deposits and withdrawals are tied to a verified account.
• Discretion. Withdrawals can be paused, limited or reviewed. That is not hypothetical for larger amounts.
• Memo and network mistakes. A deposit sent on the wrong network or without a required memo is an exchange support ticket, not an on-chain fix.

What bridging costs you

• A service fee and the destination network fee, quoted upfront.
• Responsibility for the destination address being correct — there is no support desk that can reverse a correct-but-unintended transfer.

A reasonable rule

Self-custody the whole way, no account required, and settlement in minutes: bridge. Already inside an exchange and not in a hurry: withdraw on the chain you want. If you do combine the two, read bridging to an exchange deposit address first.
