ERC-20 gas fee payments have been a long-held promise of smart accounts, but until the launch of the v1 of our ERC-20 paymaster, there has not been a permissionless implementation not requiring a centralized API to use.

While we've seen some success with our first version, we've also heard many pieces of constructive feedback.

Most notably, people wanted a way to use the paymaster in a way that doesn't require the user to approve tokens to the paymaster before the validation step of their first user operation. For many account implementations, this was simply not possible in the first version.

We deployed a paymaster to Sepolia already, and will be deploying to more chains over the coming days.

If you would like us to deploy our paymaster for a token you would like supported, get in touch!

3. the paymaster now removes the cached price mechanism in favor of directly querying the oracle for every user operation, which makes prices more accurate for users and protects the paymaster operator.

Our new version upgrades makes three major updates:

1. the paymaster now supports EntryPoint v0.7.

2. the paymaster enables the use of 'guarantors' that can front the gas fees for users with the expectation of getting paid back later.
