Last, Privy is a web3 onboarding library that handles user adoption with embedded wallets and secure authentication flows. It includes user management with analytics and a strong security posture, so it's a good option for web3 products. Privy offers a tiered pricing model, including a free plan, so it's good for smaller-scale use but also can handle enterprise needs with custom pricing.
