Good business. Clear terms.
Pay directly. Earn together.
Open a merchant’s invoice URL or scan its QR code. Connect a QIE-compatible wallet, check the configured network and stablecoin, then review the amount, expiry, payout wallet, and reward terms. Approve only the amount required. An approval is not a payment: return to submit the payment transaction.
Your receipt is on-chain.
We wait for two receipt confirmations before showing a successful transaction. Indexed history can take longer. Always verify the receipt and token transfer before delivering goods. The QR contains only a public invoice URL. Never enter a seed phrase or private key.
How rewards are backed
Merchants pre-fund campaign vaults with stablecoins. Each earned credit reserves that same amount of stablecoin. Campaign rates use basis points: 500 basis points means 5%. Minimum purchases, date windows, lifetime customer caps and available funding limit earning. The contract clips rewards to remaining budget rather than blocking a purchase.
A shared Loop Network
Reward balances cannot be transferred between customers or withdrawn for cash. Redeem with a merchant who has opted into the Loop Network. The issuing campaign’s vault pays the recipient’s current payout wallet. Check the merchant ID carefully: redemption is irreversible. Pausing or ending or permanently closing a campaign cannot take away credits already earned.
What merchants control
The connected wallet owns the profile and can update the payout wallet. Payout changes apply to open invoices, so review the latest address before paying. Merchants may pause future earning or opt out of accepting rewards. After campaign end or permanent closure, only the merchant owner can refund unused funds. Funds backing earned credits stay reserved and redeemable; pausing alone does not permit a refund.
Reward eligibility
Campaigns can use open wallet mode, require QIE ID verification, or disable rewards. QIE ID verification is not configured on this deployment; identity-required campaigns award no credits while payment remains possible. Owner and current payout self-payments are excluded by default. Explicit test invoices never earn rewards. Linked wallets cannot be reliably detected, and a public wallet address is not a unique person.
Know the limits
LoopPay v1 charges no protocol fee. Network gas is separate. Operators can approve tokens and pause transactions, but cannot move payment or campaign funds. Only exact-transfer, non-rebasing ERC-20 tokens should be approved. Token issuer freezing, wallet compromise, chain reorganizations, malicious merchant self-purchases and merchant delivery disputes remain risks. No purchase refunds, exchange rate guarantee, cash redemption, or independent security audit is provided by this MVP.
Development and demo data
Local Anvil and QIE testnet activity has no monetary value. Missing payment configuration enables clearly labelled browser demo mode. Demo invoices and campaigns stay in the browser where they were created. Globe cities, shops, and reward events are illustrative demo data. Deployment addresses, token identity, explorer and RPC are supplied by the operator from official QIE documentation. Never send real funds to a test invoice.
