Pimlico Platform

Pimlico is the gas sponsorship engine for onchain apps. Sponsor gas or let users pay in USDC, USDT or 300+ tokens across 100+ EVM chains. Now on Solana.

Pimlico is the gas sponsorship engine for onchain apps. Sponsor transactions, accept USDC, USDT, or 300+ other tokens for gas, or set policy rules. Users transact instantly, with no native tokens to buy and no fee prompts to walk away from. Wallets with hundreds of millions of users, the issuer of USDC, and the fastest-growing consumer apps all trust the same engine. Gas is where onchain apps lose their users Before a new user can do anything in your app, they're asked to buy a volatile token on an exchange, bridge it to the right chain, and approve a fee they don't understand. Every “insufficient funds for gas” error is a user you paid to acquire, then watched walk away. Pimlico removes that step entirely. You decide what to sponsor and how much; your users just see your product working. Social login or passkey, and they have never owned crypto. Mint, trade, or send: your app submits it as a smart account transaction. Our paymaster verifies your policy and pays the fee on-chain. Included in under 2 seconds on L2s. The user saw none of this. Sponsor it, let users pay in stablecoins, or set precise rules for who gets what, all through one API. Sponsor gas so users transact for free Let users pay gas in USDC, USDT & more, on EVM and Solana Set rules and budgets for what you sponsor Reliable execution with <2s inclusion on L2s Sponsor gas for every developer building on your chain, so users transact without ever holding native token. Sponsor Solana transaction fees, or let users pay them in USDC or USDT, with the same API key as your EVM chains. Whatever you're shipping, teams like yours already run it on Pimlico. MetaMask, Safe, and Trust Wallet run their smart account transactions on Pimlico. Whatever signer architecture you choose, the execution layer is already built. Your users sign up with a passkey or social login and never see a gas prompt — the way Zora sponsors gas so creators and collectors never need ETH first. Daimo and Coinflow settle transactions through Pimlico, and Circle, the issuer of USDC, builds its smart wallet infrastructure on it. Smart accounts that execute the moment agent logic fires, with no native token to fund across a fleet — the way ZyFAI runs its onchain strategies through Pimlico. Free on testnets, pay-as-you-go in production. No contracts, no minimums, no sales call required. Custom SLAs, SOC 2, and 24/7 support, built for companies that cannot afford a dropped transaction. One SDK, clean APIs, and every smart account and signer in the industry already integrated. Whatever smart account or signer you build on, it works with Pimlico out of the box. Pimlico maintains an integration and a step-by-step guide for every one below. Live on the networks builders already use Works with the wallets users already have Sponsor gas for regular wallets, with no migration and no new account. Powered by EIP-7702, live today. We cut three network round-trips out of every sponsored transaction. We call it Boosted Sponsorships. Webhooks, simulation, request logs, API-key allowlists: the tooling around the engine. The infrastructure behind the biggest smart account deployments in the industry. The engine isn't a black box. The libraries and bundler behind Pimlico are open source and battle-tested by the whole ecosystem. The open-source, type-safe ERC-4337 bundler that is the backbone of Pimlico's transaction infrastructure, the same code that has relayed 250M+ transactions in production. The most widely used TypeScript library for smart account transactions, built on viem, with first-class support for every major smart account implementation. We also co-authored the standards everyone builds on: ERC-4337, ERC-7677 and ERC-7679.
