How Sippy works
The simple version of what happens when you send money.
The short version
You message Sippy on WhatsApp. Sippy understands what you want, moves the money on the blockchain, and tells you when it's done. All in a few seconds.
A bit more detail
When you sign up, Sippy creates a wallet for you -- a smart account on Arbitrum tied to your phone number. This wallet holds your USDC (digital dollars). Only you control it.
When you send money through WhatsApp, Sippy reads your message, figures out how much you want to send and to whom, and submits the transaction. Sippy covers the gas fee (the small network cost) so you don't have to think about it.
When you use the web wallet, you have two options:
- Free gas -- Sippy submits the transaction for you (same as WhatsApp, daily limit applies)
- Direct -- you submit the transaction yourself, pay a tiny gas fee, no daily limit
What happens to your money
Your USDC lives in your wallet on Arbitrum. It's not in Sippy's database, not in Sippy's bank account, not in Sippy's control. It's on the blockchain, in a smart contract that only your keys can access.
Every transfer is a real transaction on Arbitrum. You can verify it on Blockscout or Arbiscan using the receipt link Sippy sends you.
Languages
Sippy speaks English, Spanish, and Portuguese. It auto-detects your language from your phone number, but you can switch anytime. Just talk to it in whichever language you prefer.
