Pimlico

Pimlico is a specialized infrastructure platform designed to facilitate the adoption and implementation of ERC-4337 smart accounts on Ethereum and compatible EVM chains. It provides developers with a comprehensive suite of tools including bundlers, paymasters, and a TypeScript SDK (permissionless.js) to abstract away the complexities of blockchain transaction management. By handling transaction relaying, mempool and nonce management, and gas fee sponsorship, Pimlico enables seamless on-chain user experiences without requiring users to manage gas payments directly.

The platform supports over 100 chains including Ethereum, Base, Arbitrum, Polygon, and Gnosis, with an average transaction inclusion time under 2 seconds on layer 2 networks. Pimlico's paymasters allow developers to sponsor gas fees or accept alternative payment methods like ERC-20 tokens or credit cards, enhancing flexibility for dapps and wallets. Its bundlers relay user operations reliably, ensuring fast and secure transaction processing aligned with ERC-4337 standards.

What sets Pimlico apart is its scale and maturity, having bundled over 200 million transactions and being trusted by leading crypto teams and projects. Its open-source SDK and extensive documentation lower the barrier for developers to integrate smart accounts and improve user onboarding. Pimlico’s infrastructure is designed to accelerate Ethereum’s transition to account abstraction, making it a key enabler for next-generation dapps that require gasless or sponsored transactions.

Developers can get started by accessing Pimlico’s dashboard, integrating the permissionless.js SDK, and leveraging the paymaster and bundler APIs. Comprehensive guides and community support channels are available to assist with deployment and customization.
