You have two ways to move cryptocurrency between networks: use an exchange, or use a bridge. For a direct transfer between blockchains, I would choose a bridge. A crypto bridge is a service that moves an asset from one blockchain to another, usually by locking the original token and issuing a matching version on the destination network.
That choice makes sense when you already hold funds and need them on a different chain for a specific reason, such as paying a fee, using a decentralized application, or accessing a lower-cost transaction. An exchange is usually better when you need to convert one asset into another or move between crypto and government-issued currency. If your goal is simply to put ETH on another supported network, an Across Crypto Bridge transfer is the more direct route.
What to check before bridging
Start with the network, not the token. “USDC on Ethereum” and “USDC on Arbitrum” may represent the same dollar-linked asset, but they exist on different blockchains. Select the network where your funds currently are, then select the network where you want to use them. Reversing those fields can send you into a recovery problem.
Next, keep a small amount of the destination chain’s native token for transaction fees. For example, receiving USDC on Arbitrum does not necessarily give you ETH for paying the next transaction. Without a little ETH already available, your funds may arrive safely but remain difficult to move.
Before confirming, compare the amount you send with the amount you will receive. The difference can include a network fee, a bridge fee, and price movement while the transaction is processing. For a first transfer, send a small test amount—perhaps $10 rather than your entire balance—and wait until it appears in the destination wallet.
The edge case that catches people
A bridge may deliver a wrapped token rather than the native version you expected. A wrapped token is a representation of an asset issued on another network. Your wallet can show the correct ticker while the application you want to use supports only a particular contract address. Check the application’s supported asset list and contract address before depositing.
Also verify the destination wallet address and never approve a transaction you do not understand. Bridge transfers are generally difficult or impossible to reverse once confirmed. The safest workflow is simple: confirm both networks, reserve the destination fee token, test with a small amount, and only then move the rest.
