Particle Network’s infra stack spans five SDKs. They’re independent, free to use, and designed for composability. Most apps pick a stack of two or more (for example, a signer—Particle Auth or Connect—plus Universal Accounts). This page helps you pick your stack. Use the flow chart below to find it, or jump straight to a specific scenario under “Recommended stacks”.

Launch a multi-chain app

Cross-chain UX from day zero. Universal Accounts SDK + Particle Connect (or Auth for social-only onboarding, see below).

I have an app; make it chain-agnostic

Universal Accounts SDK in 7702 mode. Keep your users and wallet provider. No migration required! 

Onboard users without seed phrases

Social logins → instant wallet. Particle Connect for wallet selection, Particle Auth for a branded custom UI.

Accept deposits from any chain

Simple Deposit, 10 lines of code. Users deposit from any chain, funds arrive as USDC in your home chain. Fully wallet-agnostic, no UX changes required.

Smart accounts, full control

Direct bundler & Paymaster access. Use ERC-4337 primitives and pair with any signer with our AA SDK.

Particle ConnectDrop-in modal for social logins and external wallets. Built-in account abstraction compatibility. → Docs
Particle AuthSocial login → EOA. Full UI customization. Pair with AA SDK for Smart Account features. → Docs
AA SDKERC-4337 bundler + Paymaster + Smart Account management. Use it directly for primitives. → Docs
Can I use Universal Accounts without Particle Auth or Connect?Yes. The Universal Accounts SDK is provider-agnostic. You can pair it with Particle Connect, Particle Auth, RainbowKit, Web3Modal, wagmi, or any signer that exposes a standard wallet provider.
