Secure, fast, and simple phone-to-crypto transfers
User verifies phone via OTP and links one or more wallets (e.g., MetaMask via WalletConnect, Bitcoin via xpub, or an in-app custodial wallet).
The backend stores phone → wallet mappings. Mappings are stored encrypted; only a hashed/obfuscated token is used in public references. Optionally anchor verification proofs or revocation metadata on a light on-chain registry (minimal on-chain footprint).
Sender inputs phone number and amount. System resolves recipient mapping and network, prompts user to sign the transaction using their chosen wallet. Transaction is broadcast to the chain.
If recipient is unregistered or opts out, funds are held in an escrow smart contract. Recipient verifies phone and claims funds. Escrow contains timeout and dispute resistant logic.
Recipient receives notification and a transaction record. Block confirmations are surfaced, and a link to a block explorer is offered.
