# Privy Integration Privy provides authentication and wallet infrastructure for apps built on crypto rails. Embed self-custodial wallets, authenticate users via email/SMS/socials/passkeys/wallets, and transact on EVM and Solana chains. Also supports agent payment protocols (x402, MPP) and autonomous agentic wallets. Key packages: - `@privy-io/react-auth` - React SDK (auth + wallets + x402) - `@privy-io/react-auth/solana` - Solana wallet hooks - `@privy-io/react-auth/smart-wallets` - Smart wallets (ERC-4337) - `@privy-io/wagmi` - wagmi v2 connector - `@privy-io/node` - Server-side SDK (replaces deprecated `@privy-io/server-auth`) - `mppx` - MPP client/server SDK (settles on Tempo) Docs: Privy ships an official agent skill - `npx skills add https://docs.privy.io` (or fetch `https://docs.privy.io/skill.md`). The machine-readable doc index is `https://docs.privy.io/llms-full.txt` (plus `sitemap.xml`); `llms.txt` now only points to the skill installer. Privy restructures docs often - do not guess URLs, they 404. ## Workflow Decision Tree **Setting up Privy auth in a React app?** -> Quick Start below, then [references/react-sdk.md](references/react-sdk.md) **Adding wagmi/viem to a Privy app?** -> Wagmi Integration below, then [references/react-sdk.md](references/react-sdk.md) **Working server-side (Node.js)?** -> Server-Side section below, then [references/server-sdk.md](references/server-sdk.md) **Adding x402 or MPP payments?** -> x402/MPP sections below, then [references/age...
