Forus: Elevating Privacy on Ethereum & Arbitrum Through Stealth Addresses and Cryptographic Innovation

Forus is a cutting-edge privacy solution built on Ethereum, optimized for Arbitrum, leveraging advanced cryptography to protect users' financial privacy. By utilizing elliptic curve Diffie-Hellman (ECDH) cryptography, Forus generates unique stealth addresses for each transaction, allowing users to receive ETH and ERC20 tokens privately via a cryptographic link, without exposing their real wallet addresses.

How It Works:

1. Elliptic Curve Cryptography & Forus Keys: Forus uses ECDH cryptography to create a key pair (public and private). The public key forms a cryptographic link, which can be shared without revealing any association with the user’s actual blockchain address. This key generation process allows for the creation of multiple, independent Forus keys for enhanced flexibility.

2. Stealth Address Generation: When a sender initiates a transaction, they use the shared public key to compute a stealth address through a real-time, off-chain operation, utilizing their own ephemeral private key. This ensures that every transaction is linked to a one-time, unpredictable stealth address, shielding both sender and receiver from any blockchain-based traceability.

3. Fund Retrieval & Privacy: Receivers monitor the Forus contract for new transactions, derive the corresponding private key using their Forus secret, and access their funds in a secure, anonymous manner. The stealth address breaks any link between sender and receiver, ensuring complete privacy in on-chain financial interactions.

Built on Ethereum's Infrastructure: Forus enhances the privacy layer on Ethereum and Arbitrum, which inherently prioritize transparency. By leveraging stealth addresses, Forus provides a practical solution to the transparency challenges of blockchain, making secure, untraceable transactions possible.

Innovations: Forus is refining its relayer mechanism to allow users to pay transaction fees in ERC20 tokens, eliminating the need for ETH. Integration with Gelato enables automated transactions, enhancing user convenience. Additionally, cross-chain transfer capabilities and NFT support are in development, further expanding Forus’ privacy-enhancing ecosystem.

Forus merges cryptographic sophistication with Ethereum’s infrastructure, offering a secure, user-friendly solution for private financial transactions on Arbitrum.
