Pimlico

aid: pimlico
name: Pimlico
description: Pimlico is the world's most popular ERC-4337 account abstraction infrastructure platform, providing production
  bundler and paymaster APIs plus a platform management API for building, deploying, and operating smart accounts on Ethereum
  and 100+ EVM-compatible chains. Its verifying paymaster sponsors gas for gasless transactions, its ERC-20 paymaster lets
  users pay gas in stablecoins and other tokens, and its bundler submits, estimates, and tracks ERC-4337 user operations.
  Developers integrate through the permissionless.js TypeScript SDK (built on viem) against a single JSON-RPC endpoint keyed
  by chain, and manage sponsorship policies, API keys, and billing through the Pimlico dashboard.
