Payments infrastructure is the aggregate of networks, rails, processors, and settlement systems that move value between parties. It spans card schemes, interbank transfer rails, clearing houses, and blockchain-based settlement layers that enable assets such as stablecoins to circulate. As a backbone system it determines the speed, cost, reach, and finality of monetary transactions.
