About TandemPay
Non-custodial payment processing for the modern merchant.
Our Mission
TandemPay bridges traditional card payments and cryptocurrency settlement, enabling merchants to accept customer payments via cards while receiving funds directly in stablecoins. Our non-custodial architecture ensures merchants maintain full control of their funds through smart contract-enforced settlements.
Core Principles
Non-Custodial
We never hold your funds. Smart contracts enforce direct settlement to your wallets.
Customer Choice
Your customers pay with familiar cards. No crypto wallet required on their end.
Transparent
All settlements are visible on-chain, with pricing tailored to each merchant's processing profile.
How We're Different
Traditional payment processors hold merchant funds in pooled accounts, creating custody risk and enabling arbitrary holds or freezes. TandemPay uses smart contracts with hardcoded settlement destinations — even if our servers are compromised, funds can only flow to merchant-controlled addresses.
This architecture makes TandemPay particularly suitable for merchants who value self-custody and transparency over traditional financial intermediation.
Legal & Compliance
Merchant applications may be subject to review (typically 1–2 business days). Contract addresses and security audit reports will be published pending legal review.
TandemPay operates with transparency and honest disclosure. We do not make unsubstantiated claims about transaction volume, merchant counts, or regulatory status.
