About

The permissionless multi-signer paymaster enable ZKsync Dapps to seamlessly sponsor gas for their users through signature verification. Dapps can begin utilizing this paymaster by simply depositing funds and adding a signer address.

There are 2 primary actors involved:

• Manager: Fully managed by the dApp, responsible for depositing/withdrawing gas funds, and adding or removing signer addresses.

• Signers: Managed by the dApp or a trusted third party like Zyfi’s API. A signer’s signature is required to access gas funds by the dApp’s user.
