How it works
Three steps. One clear flow.
Send or request value
Choose an amount, add a note, and create a payment intent. OTPay handles the product logic while the wallet stays behind the scenes.
createPaymentIntent(amount, note)Approve and settle
The other user confirms with OTP or a lightweight app flow. Then the stablecoin settlement happens on Solana while the experience still feels like normal mobile money.
approve -> settle on SolanaWhy OTPay
Built for humans, powered by rails.
User experience
No wallet-address friction
The user-facing abstraction is the phone number. That means fewer mistakes, less fear, and a product normal people can understand on first contact.
SimpleIdentity model
Your number, your linked wallet
The number is the lookup key. The Solana wallet is still the real account behind the scenes. That makes the product technically coherent and easy to explain.
Product wedge
Send and request by contact
OTPay is not just about sending money. It is about turning contact-based payment behavior into a stablecoin-native product flow.
Settlement layer
Solana underneath
OTPay uses Solana where it matters most: fast, low-cost stablecoin settlement. The blockchain is the rail, not the user interface.
Global payment foundation“We don't want people to learn wallet addresses. We want them to move value the way they already move trust, through a phone number.”
