# About

The [<mark style="color:blue;">permissionless multi-signer paymaster</mark>](https://github.com/ondefy/permissionless-multisigner-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.&#x20;
* **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.
