Holdstation Paymaster

A paymaster is a smart contract that can pay for transactions for its users, executing any logic to decide whether it should forward a transaction. For example, developers can allow users to run transactions for free or pay in your application's ERC-20 token instead. The library helps developers easily interact with paymaster contracts

npm i @thangnn91/holdstation-paymaster-helper
