Why iPayX
Stop chasing hashes across five wallets.
Traditional invoicing tools don't speak crypto. Raw wallet transfers don't scale for teams. iPayX sits in the middle: professional invoices for you, guided payment for your clients, and one Arc balance when money arrives.

How it works
Four steps from sign-in to paid
01
Sign in & get your Arc wallet
Use Google to create your Circle programmable wallet on Arc Testnet. Your dashboard shows balance, invoices, and payments immediately.
02
Create & send an invoice
Add line items, set a due date, and send to your client's email or Arc address. They receive a pay link — no iPayX account required to pay.
03
Client pays from their chain
They connect MetaMask, pick the network where their USDC lives, and confirm a guided flow. Funds route to your Arc address via CCTP.
04
You see it on Arc
The invoice marks paid with transaction reference. Your Arc balance updates; activity and overview charts reflect the payment.

Security & trust
Sessions use encrypted server-side storage for Circle credentials. Public pay links use opaque tokens — payers never see your full wallet admin keys. Always verify amounts on MetaMask before confirming.

Common questions
No. Anyone with the pay link can pay from MetaMask. If they already use iPayX, they can pay from their Arc balance while logged in.
