The illustrative route withdraws ETH from an exchange over Base directly to a Banana Gun trading wallet. Some ETH remains for gas; the rest funds a token purchase and reverse sale. Starting with USDC is a different route: it needs native USDC, ETH on Base for gas and an interface that accepts USDC as the swap input.
Two budgets, one route
Calculation snapshot: 08.10.2026 04:10 MSK
Trading interface: Banana Gun · 1% + 1%
Withdrawal fees used in the calculation: BingX: 0.000004 ETH. Conversion quotes: ETH = 2573.735 USDT. Checked 08.10.2026 04:10 MSK. The example assumes 1 USDT = $1; this is a conversion assumption, not a separate USDT/USD quote.
An illustrative direct ETH withdrawal into a Banana Gun trading wallet and two ordinary manual swaps: ETH → non-stablecoin token → ETH. The purchase and sale amounts are equal, with no price change; the tariff is 1% per swap. The ETH reserve is within the budget. Gas, token approval, pool fees, slippage, price impact and an additional transfer from an external wallet into the terminal are excluded. Base network fees include L2 execution and publishing data to Ethereum (L1); check the full estimate, including L1, before confirming.
The reserve amount is an assumption in this example, not a required amount for every trade. It remains part of your balance: only the amount spent becomes a cost. The last row is an upper bound after the accounted fees, before network costs and price changes. It is not a net trading result.

This table updates separately from the snapshot above. Before withdrawing, check the network, asset, minimum and conditions on the exchange itself. Each row shows when the data was collected, in Moscow time.
Before transferring
How can I start with USDC instead of ETH on Base? +
Withdraw native USDC and ETH over Base to your wallet and choose a DEX interface that accepts USDC as the input asset. Check Circle’s contract, token approval and the quote. This two-withdrawal alternative does not have the same costs as the calculated ETH route. Withdrawing ETH and swapping some into USDC also requires accounting for the extra swap.
Are USDC and USDbC on Base the same asset? +
They are different representations. Native USDC is issued by Circle, while USDbC is a bridged token. Before transferring, check the contract and which asset the selected app accepts.
Are two exchange withdrawal fees always required? +
The ETH calculation uses one exchange withdrawal: the same asset funds trading and gas. Separate USDC and ETH withdrawals can incur two fees. An additional transfer from an external wallet to a trading wallet also adds a network cost.
Do Banana Gun buys and sells always cost 1% each? +
This example uses ordinary manual ETH-to-token and reverse swaps at 1% per trade. EVM stablecoin-to-stablecoin swaps have a different rule; do not apply this calculation to every USDC swap. Gas and pool conditions are outside the terminal tariff.
