The amount of ETH to bridge to Manta Pacific is the amount you want available there after the transfer. First, leave enough ETH on Ethereum to pay for sending it, then plan for any activity you want to do after it arrives.
How Much ETH Must Stay on Ethereum?
Keep enough ETH in your Ethereum wallet to cover the bridge transaction’s gas fee. Gas is the network’s charge for processing a transaction, and Ethereum charges it in ETH. Your wallet shows an estimate before you approve the transfer; the amount can change with network demand.
Do not enter your full wallet balance as the transfer amount. If the bridge transaction costs more than the ETH left behind, it may fail. You may also want some ETH left on Ethereum for another transaction later.
How Do I Work Out the Amount to Send?
Start with the amount you want to use on Manta Pacific, then add any ETH you want to keep there for gas. Subtract the Ethereum gas estimate and any source-side reserve from the ETH you have available. This gives you a useful upper limit for the transfer.
- ETH to arrive: the amount you want to hold or spend on Manta Pacific.
- Ethereum gas: the sending transaction’s estimate shown by your wallet.
- Source reserve: extra ETH you choose to leave on Ethereum for later.
For example, say you have 0.052 ETH and want 0.05 ETH on Manta Pacific. If your wallet estimates 0.0006 ETH for the bridge transaction, sending 0.05 ETH leaves 0.0014 ETH on Ethereum. These are illustrative figures, not a fee quote; check the estimate at the time you send.
When bridging USDT, think about gas separately from the token amount. USDT is a token, while gas is the network charge. Plan to have ETH available for transactions on the network you are using.
What Should I Check Before Sending?
Check that your wallet is set to Ethereum as the source and Manta Pacific as the destination. Confirm the asset is ETH if you intend to receive ETH, and compare the displayed amount with your plan. Manta Bridge moves ETH and supported tokens between Ethereum and Manta Pacific.
For a first transfer, consider sending a small amount you can afford to have delayed before moving more. Once it arrives, check the receiving wallet’s network and balance. The Manta Bridge service is one way to make that transfer. My practical tip: write down the amount you want to arrive, then check the wallet’s gas estimate before choosing the send amount.
