Introduction
What is AnomaPay?
AnomaPay is a privacy-preserving payments network built on the Anoma Distributed Operating System that enables shielded transfers of any ERC20 token on EVM-compatible blockchains.
By leveraging the cryptographic power of the Anoma Resource Machine, AnomaPay allows you to transact with the assets you already own, on the networks you already use, without exposing your financial history to the public
What is the AnomaPay App?
The AnomaPay App is built on top of the AP network. The AnomaPay app enables shielded payments with any Ethereum assets. It is a web app with a very simple onboarding process and it does not require downloading any programs.
AnomaPay is currently in the Private Beta:
- It is live on Base
- Supporting USDC on Base
- Currently only accessible via an invite link
- Deposits are disabled
Beta Notice: AnomaPay is currently in the Private Beta phase. While the underlying cryptography is robust and audited, the service infrastructure (Proving and Transaction submission) is currently operated by the service providers. Please read the Security & Trust section for more details.
Why AnomaPay?
Public blockchains like Ethereum differ from traditional bank accounts in one major way: Transparency. On a public chain, your balance, transaction history, and counterparties are visible to anyone with an internet connection and knowledge of your address. Once your address is known, your financial activity is transparent.
AnomaPay solves this by introducing the Shielded Pool concept to EVM chains.
- Privacy-Preserving: Once assets are shielded, internal transfers between AnomaPay users are only visible to the involved users.
- EVM Compatible: We support major EVM networks (see Supported Networks). You don’t need to bridge funds to a separate privacy chain.
- Gas Abstraction: Pay for gas in any token as part of your payment. The underlying complexity of gas management is handled by our infrastructure.
Core Concepts
- The Anoma Protocol Adapter: At the heart of AnomaPay is the Anoma Protocol Adapter. This is a smart contract deployed on every supported EVM chain. It acts as the “anchor” for the system, controlling shielded funds via deployed forwarder contracts and verifying the cryptographic proofs that authorize transfers.
- Shielded vs. Transparent:
- Transparent (Public): Your standard ERC20 tokens held in a wallet.
- Shielded (Private): Tokens that have been deposited into the AnomaPay application. While the total shielded pool balance is public, who owns which tokens within the shielded pool is private, known only to the token holder themselves.
