Social Login. Embedded Wallet.
Customers sign in with Google, Email, SMS, or Apple. An embedded wallet ensures payment accuracy. Correct chain, correct token, fully recoverable.
Traditional crypto payments show customers a wallet address and hope they send the right token on the right chain. Wrong-chain errors lose funds permanently. Merchants need multiple deposit addresses per chain. And if a customer loses their wallet, the funds are gone forever.
PYMSTR uses Web3Auth to offer 7 login options. Google, Email, SMS, Apple, MetaMask, WalletConnect, and Coinbase Wallet. Social login creates an embedded MPC wallet that serves three purposes: it eliminates wrong-chain/wrong-token errors through payload validation, it removes the need for merchants to manage multiple deposit addresses, and it ensures customer funds are always recoverable through social and guardian recovery.
Three steps, on-chain.
