Numpay is financial infrastructure for moving money across borders. It turns a mobile number or email address into a wallet, settles every payment on-chain in dollar-pegged crypto, and hides the blockchain behind an interface that feels like any other payments app.

​
Built for global money transfer

  • Cross-border payments settle in seconds, not days. A Numpay transfer is an on-chain transfer on Base and is final within seconds.
  • Recipients only need to verify their mobile number or email. No bank account, no wallet app, no seed phrase.
  • No transfer fees and no FX markups. Payments are in dollar-pegged crypto, and Numpay pays the network fee.
Numpay resolves a contact to a wallet and settles the payment on Base. Numpay resolves a contact to a wallet and settles the payment on Base.

Mobile numbers become wallets

Every Numpay user has a smart wallet whose address is derived from their sign-in key. Numpay keeps a directory that maps each verified mobile number or email to that wallet, so a sender only has to know who they are paying, never a 42-character address. If the person being paid hasn’t joined yet, Numpay reserves a claimable wallet for their number. The money is delivered to their own wallet the first time they sign in.

Why it’s better for remittances

It is simple

No bank and no crypto knowledge needed. A mobile number or email is enough to send, receive and request money.

Built for performance

Payments inherit the reliability, speed and tamper-resistance of the Base network, and the app installs on any phone as a lightweight web app.
