Suggestion: Allow Paying Gas Fees with the Token Being Used in the Transaction

Current Problem:
When users want to swap, bridge, or perform any transaction across networks, they must hold the native gas token (ETH, MATIC, BNB, etc.) to cover gas fees.
This system is inconvenient because:

It forces users to buy small amounts of each network’s native token.

It complicates cross-chain operations (for example, moving funds from Base to Linea).

It confuses new users who don’t understand why they can’t use their stablecoins or other tokens directly for gas.

Proposed Solution:
Enable MetaMask to automatically pay gas fees using the token involved in the transaction, by performing a micro-swap in the background.

In practice:

The user selects a transaction (send, swap, or bridge) with any token (e.g., USDC).

MetaMask estimates the gas fees required on both the source and destination networks.

A tiny portion of the token being transferred is automatically swapped for the exact amount of the native token needed to cover gas fees.

The user doesn’t need to manually hold or buy gas tokens anymore.

Practical Example:
You want to send USDC from Base to Linea:

  1. You only have USDC on Base.

  2. MetaMask detects that gas fees will be required on both Base (ETH) and Linea (ETH).

  3. Before executing the bridge, MetaMask automatically swaps a very small part of your USDC for the equivalent amount of ETH needed to cover gas on both networks.

  4. The entire operation is completed in one click, with no manual intervention.

Advantages:

Simplified user experience: no need to manage or pre-purchase native gas tokens.

Easier onboarding: new users can use MetaMask without understanding gas mechanics.

Full interoperability: smoother cross-chain operations.

Automatic optimization: MetaMask could dynamically calculate and convert only the minimal amount of gas required.

Potential Impact:
This mechanism would make Web3 transactions as seamless as traditional payments: you simply hold one balance, make a transaction, and MetaMask handles the technical side invisibly.
It’s a step toward a “smart MetaMask”, capable of auto-managing gas for users — a revolutionary improvement for mainstream crypto adoption.

Hi @orionp99 and thanks for creating this post!

MetaMask does have this feature, it’s called MetaMask Gas Station. Though at this time it’s available only on the Ethereum Mainnet and BNB Smart Chain network and for a limited list of tokens with other popular networks to come in the future. For other networks, MetaMask offers the ability to purchase tokens with fiat via the MetaMask Buy feature, or you can swap tokens from another network using the bridge. This provides you with a convenient way to top-up your gas balance and continue with your swap.

Thanks @Coffee7643!

Yes, I know about the Gas Station feature — my suggestion goes a bit further.
The idea is to make gas payments completely transparent by allowing users to pay gas fees directly in the token they’re swapping, without needing a separate ETH (or native token) balance.

For example, if I’m swapping USDC to ETH, the gas fee could be automatically deducted from my USDC instead of requiring ETH in my wallet.

That way, users wouldn’t get stuck with a “Gas insufficient” message when they don’t have native tokens, and the experience would feel much smoother and more intuitive.

Basically, it’s about simplifying the user experience and removing the friction caused by managing gas tokens manually.

It would be so amazing to be able to do that, and it would make Metal Mask accessible to the general public, which would be a major innovation and help democratize cryptocurrency.

Suggestion: Automatically convert a small portion of USDC into ETH on Linea to cover gas fees

Hello,

I live in France and face a recurring issue whenever I want to buy cryptocurrency from an external provider: I always have to complete a full KYC process (photo capture, ID scan, personal information entry…). It’s time-consuming, especially late at night when lighting is poor.

Currently, I have 80 USDC on the Linea network to test the MetaMask card — which I find absolutely brilliant. The idea of a debit card linked to a decentralized wallet is a true innovation.

However, I’ve used up the small amount of ETH provided by MetaMask (around $0.25), and now I’m stuck: without ETH, I can’t move my USDC. Yet, no major exchange — not even Binance — currently allows users to buy ETH directly on the Linea network.

The only current solution is to buy at least €10 worth of ETH via a provider like Transak, with about €3 in fees, several minutes of KYC verification, and the need to re-enter my banking information. In France, this also raises additional administrative constraints since every foreign account must be declared, which makes the process even more complex.

All of this could be avoided if MetaMask introduced a feature allowing users to automatically swap a small fraction of their USDC on Linea into ETH on Linea, seamlessly and transparently during a transaction.

This improvement would make the experience much smoother:

  • no need to manually buy ETH for gas fees;

  • saving both time and money;

  • avoiding regulatory complications linked to external purchases;

  • making MetaMask more accessible to the general public.

In short, such a feature would significantly simplify the user experience and further strengthen MetaMask’s decentralized vision.

Thank you for your time and for the innovation you’re already bringing with the MetaMask card.
