What is Pimlico Paymaster?
Pimlico Paymaster is an ERC-4337 compliant paymaster service that provides two types of paymasters, Verifying and ERC-20, to abstract away gas fees for users. The Verifying Paymaster allows developers to load an off-chain Pimlico balance through their dashboard and sponsor onchain gas fees for users on 100+ chains. The ERC-20 Paymaster is a permissionless on-chain smart contract that lets users pay for their own gas fees using their ERC-20 tokens.
