The Amazon ecosystem encompasses four primary ecological roles: regular users, merchants, market makers, and gateways and financial institutions. These ecological roles collectively form Amazons global payment ecosystem, making finance simpler and payments more efficient. Ultimately, it becomes the underlying infrastructure of the financial industry, enabling industrial upgrading of financial services. Anyone, and any business entity, can conduct various financial transactions such as cross-border payments, B2B business, supply chain finance, loyalty programs, asset management and trading, in a decentralized, cheaper, and faster way.
