Everyday users and institutions require a certain level of privacy akin to a traditional bank account before they will feel comfortable adopting stable coins for everyday usage. Stablecoin transactions on public blockchains expose sensitive data, including amounts, senders, and recipients, leading to significant privacy concerns for both businesses and individuals.\n\nIn addition, existing privacy solutions either require the use of specific blockchains or do not adhere to regulatory or compliant standards.\n\nAxiompay enables private and secure stable coin transfers by decoupling privacy from the underlying blockchain in a regulatory compliant manner through the use of smart contract directly deployed on-chain. We believe that enabling private transfers will significantly drive the adoption of stable coin usage for both individuals and institutions.\n", "hidden": false, "question": "How does your project contribute significantly to the Ethereum network's infrastructure?
