Fund a Batched Smart Account on Mantle with MNT

You can fund a batched smart account on Mantle in two ways: send MNT to its address or use a paymaster that covers the gas. The batch groups actions into one request, but the account still needs a way to pay the network fee.

That distinction matters when you plan a swap followed by a transfer. Your tokens cover the actions; MNT or a sponsor covers the transaction’s gas.

What does a batched smart account need?

It needs the right assets at the right address on Mantle, plus a gas payer for the batch. If you are sending tokens into the account, confirm that the account address is the one your wallet or app will use on Mantle.

A batch can combine steps that would otherwise need separate wallet approvals, such as approving a token and then swapping it. Those steps still execute on-chain, and their gas is calculated for the whole request. Batching can reduce the number of separate submissions, but it does not make the work free.

If your funds start on Ethereum, account for both sides of the move: Ethereum gas for the deposit and MNT for transactions on Mantle. The mantle bridge guide covers the checks to make before sending across.

How do you send MNT to the account?

Send MNT on Mantle to the smart account’s address, then check that the balance appears there before submitting a batch. Use the Mantle network in your wallet and verify the destination address in the account app; sending to a different address or network will not fund the account you intend to use.

If you are moving funds from another chain, you can bridge MNT or bring another supported asset over and swap part of it for MNT on Mantle. The first route gives you gas directly; the second adds a swap and therefore another action to pay for. Keep enough MNT for the swap itself if you choose the second route.

Before sending, check these details:

• The account address and Mantle network match the app you plan to use.
• The asset is MNT on Mantle, rather than a token with a similar name on another network.
• Your balance leaves room for the first batch’s estimated gas.
• The batch preview lists the actions and any token approvals you are signing.

Can a paymaster cover the gas?

Sometimes: a paymaster can sponsor a smart account’s gas or accept another token, if the app supports that option. In that setup, you may be able to submit a batch without holding MNT, but the sponsor sets the terms and may limit which actions or assets qualify.

Check the fee payer shown in the transaction preview. If the app says the sponsor will pay, confirm that the sponsorship applies to the full batch and not just one action. If it does not, keep MNT in the account so the request does not fail for lack of gas.

For most users, keeping a small MNT balance in the smart account is the simplest fallback. Sponsorship can make a first transaction easier, but it depends on the app’s rules and availability; MNT gives you a direct way to pay.

Before you submit, watch the batch’s fee estimate and its named payer. If either changes when you edit the actions, recheck the balance or sponsorship terms before signing.
