# Moving stablecoins across chains: bridge or exchange? A bridge or burn-and-mint system moves token value through a cross-chain mechanism. An exchange route deposits into a custodial account and later withdraws on another supported chain. Both can change where value is available, but they create different custody, asset-identity and completion risks. Check the exact token received, not just the displayed dollar amount.

([Cross-Chain Transfer Protocol](https://developers.circle.com/cctp)) - **Custody:** An exchange deposit requires that service to recognize and credit the supported asset/network. ([Steps to receive crypto](https://help.coinbase.com/en/coinbase/trading-and-funding/cryptocurrency-trading-pairs/steps-to-receive-crypto)) - **Completion:** A source-chain transaction does not by itself prove destination availability. ([Cross-Chain Transfer Protocol](https://developers.circle.com/cctp)) ## Inspect what crosses the boundary Some systems lock an asset and issue a representation; others burn an issuer-supported asset and mint it on another network. These structures leave different claims in the recipient’s wallet. For a CCTP-style USDC transfer, the source burn, required attestation and destination mint are distinct steps. The service’s supported networks and current transfer mode determine the exact workflow. A burn receipt alone is not the final received balance. Evidence: [Cross-Chain Transfer Protocol](https://developers.circle.com/cctp) ## Treat custody as part of the route An exchange route first needs a valid deposit and internal credit. The holder then requests a supported withdrawal on the destination chain. During that process, access depends on the platform’s account and withdrawal controls. An exchange listing a token does not establish that it supports every deposit or withdrawal network. Check both ends of the route before sending the initial deposit.

A route delivering a third-party wrapped token is not equivalent to one delivering native issuer USDC simply because both show a dollar label. If the process stops midway, identify the last completed step and its reference. Repeating the whole route can create another transfer rather than complete the original one.

Changing the wallet’s displayed network does not transfer assets. A supported cross-chain or custodial deposit-withdrawal process must actually move the value and establish the destination balance.
