Proprietary service (React SDK Apache-2.0)

Hosted auth and embedded wallets: users sign in with email, SMS, socials or passkeys and get a wallet, and you can also connect external EVM and Solana wallets. SDKs for React, React Native, Swift, Android, Flutter and Unity. Chain support comes in tiers: Privy sends transactions on EVM chains and Solana, only signs on XRPL, Sui, Stellar, Aptos and NEAR (you broadcast), and only creates keys and signs on TON. Avalanche C-Chain is in its default EVM network list. Free up to 499 monthly active users, then $299/month; the React SDK is Apache-2.0 but the service is closed.
