- The system links Mastercard payments to onchain crypto purchases using Chainlink infrastructure and fiat conversion partners like zerohash.
- Users can buy crypto through card payments, with execution routed to Uniswap liquidity through Swapper Finance and XSwap systems.
- The rollout connects traditional payment rails with DeFi, aiming to simplify onboarding and expand global access to digital assets.
Chainlink and Mastercard announced a partnership aimed at enabling roughly 3.5 billion Mastercard cardholders to purchase crypto assets directly onchain. The integration connects traditional payment rails with decentralized finance systems through fiat-to-crypto conversion. The rollout involves zerohash, Swapper Finance, Shift4 Payments, and XSwap, while leveraging the Uniswap protocol for decentralized liquidity execution.
Payment Networks Link To Onchain Infrastructure
Chainlink said the system uses its interoperability infrastructure alongside Mastercard’s global payments network. The setup allows cardholders to convert fiat currency into crypto assets through a structured onchain process.
According to Chainlink Co-Founder Sergey Nazarov, the collaboration links traditional payments with decentralized exchanges. He stated that the integration connects billions of Mastercard users to onchain trading environments.
Mastercard executive vice president Raj Dhamodharan said users want simpler access to digital assets. He added that the partnership focuses on bridging onchain commerce with offchain transactions through existing payment systems.
Notably, zerohash provides fiat conversion and liquidity services for smart contract execution. Shift4 Payments handles card processing, while Swapper Finance manages the application layer experience.
Infrastructure Partners Enable Crypto Conversion Flow
The system routes fiat payments through multiple infrastructure providers before onchain settlement. Swapper Finance uses XSwap technology to connect users to decentralized exchanges.
XSwap operates within the Chainlink ecosystem and sources liquidity from protocols such as Uniswap. This structure allows trades to execute directly onchain after fiat conversion.
According to zerohash CEO Edward Woodford, the infrastructure abstracts smart contract complexity. He said the system supports compliant onboarding and transaction execution across crypto and fiat networks.
Meanwhile, Uniswap Labs Head of Business Development Drew Turchin noted the protocol’s role in decentralized market infrastructure. He said the system continues to support developer-built financial tools across onchain markets.
DeFi Integration Expands Payment Use Cases
Chainlink said the collaboration aims to unify traditional payment networks with decentralized finance systems. The integration uses standardized interoperability tools to connect multiple financial layers.
Additionally, Mastercard’s network provides access to global cardholders, while Chainlink supplies data and communication infrastructure for blockchain execution. Together, the system enables fiat payments to trigger onchain crypto transactions.
The partnership connects payment processing, liquidity provisioning, and decentralized exchange execution into a single flow. It uses regulated onboarding systems alongside decentralized liquidity pools to complete transactions.
