Gas deposit on blockchain

Provide a brief description of the feature you would like to see implemented.

I had an idea and I just want to share it so as not to forget. I share it with you, because you treat the community well and really respond to all messages (for which I respect you a lot). What if in the blockchain (perhaps through a smart contract) it is possible to have a deposit for gas? Like a restaurant deposit for big events. That is, the user knows that he will often make transactions in this blockchain and he is too lazy / there is no time to pay for gas and constantly press the Confirm button - for such a user it would be a good option to deposit 10-100 ETH for gas and just keep transactions until the deposit runs out. From the side of the blockchain, it is possible to run nodes that will take such transactions as the first priority and carry them out as quickly as possible, and if there are no such transactions, they will carry out ordinary transactions. You can also offer the user as an advantage of the deposit - this is a 10-20% discount on gas, or an "average" and stable gas price. It seems to me that the idea here is win-win: the user gets faster and cheaper transactions, and the blockchain earns on the deposit.

If you at least read this - for me already a victory! Thanks for ur work!

Who does this feature request benefit the most (users, developers, protocol, etc.)?

Hey,
Thank you for your idea!

I believe the features you are describing can all be implemented thanks to paymasters. You can deploy paymasters that will cover all the gas fees for specific smart-accounts. It can be funded in ETH, and cover gas fees in any ERC-20 token you wish.

In general, we could see emerge a market for paymasters(-as-a-service) offering deposits, gas payments, liquidity pools etc.

expanding on that, paymasters on Era can be used to allow any account (both smart contract accounts and EOAs like Metamask) to pay gas fees with ERC20 tokens like USDC or even do gas-less transactions. The paymaster will always pay the gas fees in ETH behind the scenes. You can read more about paymasters in this section of the docs and find examples in this open source repo that we created.

I think the scenario that you mention, even if you could create a paymaster to remove the gas fees from the equation, users still have to sign their transactions but you could abstract this in many different ways with account abstraction
