Forus introduces pioneering work in enhancing privacy through the use of stealth addresses powered by elliptic curve Diffie-Hellman (ECDH) cryptography. This method ensures that users can receive ETH and ERC20 tokens without ever exposing their real wallet addresses, preserving their privacy in on-chain transactions.

In terms of user experience, Forus simplifies transaction processes by integrating a relayer mechanism that allows users to pay gas fees in ERC20 tokens rather than ETH. This eliminates the common hurdle of needing ETH for gas, making transactions more user-friendly and reducing friction for new or non-technical users.

For future interoperability, Forus is also working on cross-chain solutions, enabling users to privately receive and send funds across multiple blockchains, further expanding privacy and flexibility for users in the decentralized ecosystem. These innovations push the boundaries of privacy and usability within Ethereum and beyond.
