How to Withdraw Exchange Funds to a Berachain Route
When the chosen bridge route accepts the token on Ethereum, Arbitrum or Base, you can help your friend withdraw it from an exchange to their own wallet, with ETH on that same network for gas. The network in the exchange form must match the route’s supported source network; a matching token name alone is not enough.
Which withdrawal network should they choose?
Choose the exchange network that matches a source network listed for the exact Berachain bridge route they plan to use. Exchanges may label Ethereum as ERC20, while Arbitrum One and Base may appear by those names; compare the actual network, not just the wording or fee shown in the menu.
The bridge can only pick up assets that are already in a wallet the person controls on a supported source network. Ethereum.org’s “Bridges” documentation explains that assets exist on specific networks and need a bridge to move between them. If the exchange offers a direct withdrawal to Berachain for that token, the person may not need to bridge it at all.
If the person still needs to prepare their wallet and route, what to set up before Berachain bridge covers that distinct step. Here, the decision is the exchange’s withdrawal network: it determines where the funds first arrive, and therefore whether the selected route can use them.
How do you match the withdrawal and gas?
Have your friend confirm which source networks and tokens the chosen route accepts, then copy their receiving address directly from their self-custody wallet app. A self-custody wallet is one they control with their own saved recovery phrase. They should select the matching token and network in the exchange form, review the address, and approve the withdrawal themselves using the exchange’s security checks.
Send a little ETH on the same network as the token. The token is the asset the bridge route will pick up; ETH pays the source-network transaction fee when the person later starts the bridge transaction. ETH on Ethereum does not pay a fee on Arbitrum or Base, so the network must match even though the gas token is also called ETH.
- Token: the asset and source network accepted by the chosen route.
- Gas: a small amount of ETH on that same network.
- Destination: the person’s own wallet address, copied from their wallet app.
These parts work together: the token must arrive where the route can see it, and the wallet needs network gas to submit the bridging transaction. Once both balances appear on the chosen network, the funds are ready for the Berachain bridge.
How should you weigh fees against route fit?
For this situation, I’d choose a supported network first, then compare its withdrawal fee with the other supported options. An Arbitrum or Base withdrawal is often cheaper than Ethereum mainnet, but exchange fees vary; a lower fee does not help if that network is absent from the route’s source list.
There is a practical trade-off: cheaper withdrawals can reduce the cost of getting funds out of the exchange, while selecting a network the route accepts avoids another transfer to move the assets later. The route’s source list decides which networks qualify. The withdrawal fee decides which qualifying option suits the person’s budget.
After withdrawal, have your friend open the wallet on the selected network and confirm that both the token and ETH appear there. If either is missing or on a different network, pause before starting the bridge: the wallet balances show whether the withdrawal landed as intended.
