RainbowKit is a wallet infrastructure for accounts, authentication, signing, and transaction workflows. It helps Web3 teams work with blockchain applications, smart contracts, wallets, data, and onchain infrastructure using a focused product or developer workflow.

Use it for:

• Add wallet onboarding to applications.
• Manage account and session flows.
• Sign transactions and messages.
• Improve user experience around Web3 actions.

Best fit: product teams that need wallet features without rebuilding the full stack.
