OpCredit

Pay Later.
Zero trust required.

The world's first Bitcoin-native buy-now-pay-later — secured by an OPNet smart contract on Bitcoin Layer 1. No credit check, no identity, no risk for the buyer.

🔒
BTC locked in escrow — right now
Your Bitcoin is locked in an OPNet smart contract. The merchant can see it but cannot touch it yet. You're protected from day one.
📦
Merchant ships — no payment yet
The confirmed escrow acts as a payment guarantee. The merchant ships your order knowing the BTC is locked and real — but still unreleased.
✓
Confirm receipt → BTC released instantly
Order arrived? Tap "Confirm Received" in OpPay and the BTC transfers to the merchant on-chain. Done in seconds.
↩
Return the order → full BTC refund
Not happy? Dispute the escrow. Once the merchant confirms the return, your BTC comes straight back to your wallet. No questions asked.
🔒 Smart-contract secured
🕵️ No identity required
↩ 100% refundable

Privacy

Zero KYC.
Total anonymity.

Bitcoin was built to be permissionless. OpPay respects that. We never collect personal data. No registration, no verification, no surveillance — just peer-to-peer payments the way Satoshi intended.

🌍
Every currency — because it's Bitcoin
OpPay displays prices in EUR, USD, GBP, JPY, CHF, AUD or CAD — but every payment settles in BTC on-chain. No currency conversion risk, no exchange markup.
🚫
No chargebacks — ever
Bitcoin transactions are final. Unlike cards, no one can reverse a confirmed on-chain payment. Merchants receive funds — period.
⚡
Instant access, anywhere in the world
No bank approval. No waiting periods. Whether you're in Amsterdam, Lagos, Buenos Aires or Taipei — OpPay works the same.
