Pimlico
Pimlico provides account abstraction infrastructure including paymasters and bundlers. They offer two types of paymasters to abstract away gas fees for users in the ERC-4337 ecosystem. A verifying paymaster allows developers to sponsor on-chain gas fees for users, it utilizes an off-chain Pimlico balance loaded through a dashboard and an ERC-20 paymaster which is a permissionless on-chain smart contract that enables users to pay gas fees using their ERC-20 tokens and operates without requiring developer intervention.
Pimlico's paymasters can be seamlessly integrated with permissionless.js, a TypeScript library built on viem for ERC-4337 development .
