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”.

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.

SDK glossary

A one-line summary of everything Particle Network ships.
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.
