How to Fund a Smart Account on a New Chain

To use a smart account on a new chain, send it the assets needed for the first action and arrange payment for that chain’s transaction fee. The amount depends on the action and the network’s fee market; a wallet may estimate it before you submit.

What does a smart account need before its first transaction?

It needs the asset you want to use, plus a fee route supported by the wallet. On many EVM chains, fees are paid in the network’s native token, while an ERC-4337 paymaster can sponsor a transaction or accept another supported token under its own rules.

The account’s address may be visible before its contract is deployed. In an ERC-4337 flow, a factory can create the account as part of its first operation, so an empty address alone does not show that something went wrong. The wallet should indicate whether the first action includes deployment.

How do you move funds onto the new chain?

Choose the destination network in the wallet, then use a bridge or exchange route that supports both the source asset and destination chain. Check the destination token and network before confirming: a token with the same ticker can be a different asset, and a transfer sent over the wrong network may not arrive in the account you expect.

If the funds arrive as a token the first action cannot use, a swap may be needed. A ParaSwap guide to bridging and swapping in fewer steps covers that combined route in more detail. A single route can reduce manual steps, but its quoted output, fees and supported networks still need checking before approval.

Can you fund the account without native tokens?

Sometimes. A wallet or application may offer sponsored gas or token-based fees through a paymaster, but support is chain- and transaction-specific; if that option is absent, the account needs the native token to pay for the operation.

• Confirm the destination chain and account address in the wallet.
• Check which asset the first action requires.
• Review the fee estimate and whether sponsorship applies.
• Send a small test amount when a transfer route or address is unfamiliar.

For most users, the simplest setup is to bridge the needed asset and a small amount of the chain’s native token, unless the wallet clearly offers a supported sponsored route. The wallet’s fee estimate and the bridge or swap quote determine the amount to send; the exact fee and whether a first transaction deploys the account remain chain- and wallet-specific.
