Learn more](https://www.pimlico.io/products/transaction-infrastructure.md) Your installed base ### Your existing users go gasless. No migration. A wallet's hardest constraint is its installed base: millions of existing users on plain EOAs who cannot be asked to move funds or change addresses. Pimlico sponsors batched, gasless transactions straight from those existing accounts, so smart account features ship to the users you already have, not just new signups. Powered by EIP-7702 and ERC-5792, live today. [See how EIP-7702 sponsorship works](https://www.pimlico.io/products/gas-sponsorship.md#eip-7702) 1 EOA signs an authorization An ordinary wallet account, with no smart contract deployed and no assets moved. 2 Pimlico sponsors and bundles The paymaster verifies your policy and pays the gas, same as any smart account. 3 Transaction confirmed The account is unchanged: the user kept their address and their keys. Works with your stack ## Every signer. Every smart account. Pimlico sits below your key management layer, so whichever architecture you pick, it already works.

Any viem-compatible signer (a LocalAccount, an EIP-1193 provider, or a WalletClient) plugs in as the smart account owner. So choose key management for product reasons: if you re-platform signers later, the switch never touches your transaction infrastructure. **any-signer.ts** ```typescript // Any viem-compatible signer works as an owner: // a LocalAccount, an EIP-1193 provider, or a WalletClient. const owner = privateKeyToAccount("0x...") // local key // const owner = await providerToSmartAccountSigner(eip1193Provider) const account = await toSafeSmartAccount({ client: publicClient, owners: [owner], // Privy, Turnkey, passkeys: if it can sign, it works version: "1.4.1", }) ``` Every network your users expect, one integration EthereumEthereum BaseBase ArbitrumArbitrum OptimismOptimism PolygonPolygon BNB ChainBNB Chain AvalancheAvalanche [See all integrations](https://www.pimlico.io/integrations.md) Wallet scale ## Infrastructure that holds when your wallet spikes Serving millions of users means traffic bursts, re-orgs, and support tickets. Everything between “user tapped” and “confirmed on-chain” is the engine's job, not yours.

If you are starting fresh, permissionless.js creates accounts in a few lines. **Can our existing EOA users go gasless without migrating?** Yes. With EIP-7702, Pimlico sponsors batched, gasless transactions straight from existing EOAs. Your users keep their address and their keys, and nothing about their account changes. **Can we run the bundler ourselves?** Alto, the bundler behind Pimlico’s infrastructure, is open source and you are free to run it. Wallet teams use the hosted platform for the multi-chain coverage, monitoring, SLAs, and the sponsorship engine on top. **Which chains can our wallet support?** All 100+ chains Pimlico runs on, including Ethereum, Base, Arbitrum, Optimism, Polygon, and Gnosis, through one integration. If your users need a chain we have not launched yet, talk to us. We partner with new chains continuously.
