Before sending funds from an exchange to another chain, prepare a self-custody wallet and verify the destination address, asset, and gas needs; then try a small transfer before moving the full amount. If you still need to choose a route, read which bungee bridge route fits your transfer; this guide starts once you know the source chain, destination chain, and token. A bungee bridge aggregator can help find routes, but you still need to check what your wallet must do on each chain.
- Your address can be the same on two EVM chains, but your balance and assets are separate on each.
- Budget for the source transaction and check how the route handles destination gas.
- Confirm the token contract and destination transaction before treating the transfer as complete.
Prepare the wallet before you sign
Use a wallet that can access both networks, and check the exact token and chain shown for each side of the transfer. A familiar token name or ticker alone is not enough: a token can have different contract addresses on different chains, and a bridged version may not be the same asset as the one you hold on the source chain.
- Check which wallet holds the funds. Open the wallet where you plan to send from and verify that it is set to the source network. A balance on Ethereum does not mean the same address has that balance on Base.
- Confirm both networks. Match the source and destination chain names to your intended transfer. For example, “Ethereum to Base” means the transaction starts on Ethereum and the receiving asset should appear on Base.
- Check the token on each chain. Look at the asset name and, where available, its contract address. If the destination token is a bridged representation, check whether it is accepted by the app where you plan to use or exchange it.
- Leave enough source gas. The source chain’s native gas token pays for the transaction that starts the transfer. On Ethereum, that is ETH; on Base, it is also ETH. The amount needed varies with network activity and the transaction, so check the estimated cost immediately before signing.
- Check how destination gas is handled. Some routes deliver only the chosen token, while others may account for destination gas in the amount received. If you will need to make another transaction on the destination chain, make sure you will have its native gas token there.
- Review any token approval. A wallet may ask you to approve a contract to spend a token before the transfer can start. Check which token and spending contract the wallet names, and approve only what the route requires.
A route can have several cost components: source gas, a bridge or liquidity fee, and possibly a deduction for destination gas. The final amount received may therefore be lower than the amount entered. Compare the displayed output and expected completion time, and consider whether the difference is acceptable for the amount you are moving.
What happens after the source transaction?
A cross-chain transfer usually takes more than one transaction. Your wallet signs the source-chain transaction; depending on the route, a protocol may lock or burn the source tokens, or a liquidity provider may front the destination tokens. A message or proof then lets the destination side release or mint the corresponding asset.
That sequence explains why a confirmed source transaction does not always mean the funds are already spendable on the destination chain. The route may need to wait for source-chain finality, which is the point at which a transaction is considered settled, and then complete a separate destination-chain action. Across Protocol and Stargate are examples of protocols that can appear in cross-chain routes; the exact transfer mechanism depends on the route selected.
Keep the source transaction hash, the unique identifier for that transaction, until the destination balance updates. Check it on the source chain’s block explorer, then check the destination wallet on the correct network. If the source transaction confirms but the destination transfer remains pending, use the route’s general status or transaction-tracking information to understand whether processing is still underway. Avoid starting a second transfer simply because the first one has not appeared yet.
Walk through a small transfer first
Suppose you want to move a stablecoin from Ethereum to Base before using it in a Base app. The route you choose determines how the transfer is carried out, so treat the following as a check of the wallet and result rather than a promise that every token or route is available.
- Choose a test amount you can afford to move. A small test may still incur transaction costs, so make it large enough to meet any route requirements but small enough that a mistake would be manageable.
- Review the route’s source and destination details. Confirm Ethereum and Base are shown in the right order, the source token is the one you hold, and the expected destination token is acceptable to you.
- Check the amount you expect to receive. Account for the quoted output and any stated fees or gas deduction. The amount can change before execution if market prices or available liquidity move.
- Sign only after checking the wallet prompt. Make sure it is asking for the intended transaction or token approval. A wallet prompt is the final chance to catch a wrong network, asset, or contract before submitting.
- Wait for the destination result, then verify it. Confirm the destination transaction or balance on Base and check that the token is the one you intended. If the test behaves as expected, you can repeat the process with the remaining amount.
Keep the private key or recovery phrase out of websites and messages; a legitimate transfer route does not need you to disclose it. If an address, token, or approval prompt does not match the transfer you intended, stop and resolve the mismatch before signing.
Common follow-up questions
Can I use the same wallet address on both chains?
Many wallets use the same address across EVM networks such as Ethereum and Base. The address stays the same, but each chain has its own balances and transaction history. Switch the wallet to the destination network to check the received asset, and confirm the token contract if the token is not displayed by name.
Why did the source transaction confirm but the token has not arrived?
Source confirmation is only one part of the transfer. The route may still be waiting for finality or for a destination-chain transaction to complete. Check the source transaction first, then consult the route’s status information and destination explorer. If the destination action is pending, allow it to finish before attempting another transfer.
Do I need ETH on Base after bridging from Ethereum?
ETH is Base’s native gas token, so you generally need some to make transactions there. Whether you receive any as part of the bridge transfer depends on the route and its quoted output. Check the expected destination balance before sending, especially if you plan to swap or use the token in an app right away.
