# How We Address Them Privax aims to resolve these issues by introducing a **private state** managed by the wallet and integrating external services to help users manage virtual assets across blockchains without requiring deep technical knowledge. *** #### πŸ” Wallet Key Management * **Account Abstraction (AA)** and **Multi-Party Computation (MPC)** **AA** decouples account logic from the address in EVM chains, allowing smart contracts to perform actions typically reserved for EOAs (Externally Owned Accounts).\ Benefits include: * Multi-signature support * Automated transactions * Built-in compliance logic **MPC** in UTXO chains like Bitcoin enhances security by distributing key control across multiple parties.\ Benefits include: * No single point of failure * Decentralized control * Compliance facilitation > πŸ†š Compared to mnemonic keys, AA and MPC offer superior security and operational flexibility. *** #### πŸ•΅οΈβ€β™‚οΈ Private State Management Privax maintains a **local private state**, enabling **pluggable circuits** (algorithms) to compute proofs in an isolated environment.\ Only the **zero-knowledge proof** (ZKP) is exposed externally. **Examples:** * **DeFi Protocol Swap**: Circuit computes proof using a private input (e.g., passport data).\ β†’ Proof is used in on-chain swap, validated by smart contract. * **Privacy-Preserving P2P Protocol**: Notes are processed to generate nullifiers and proofs.\ β†’ Ensures anonymity and double-spending prevention. *** #### πŸ” Advanced Payment Routing Tokens like **USDC** exist on multiple chains. Users often lack balance or gas tokens on destination chains.\ Privax integrates **bridges** and **routing automation** inside the wallet, allowing: * Seamless token bridging * Automatic gas token top-up * Refund and fallback handling *** #### β›½ Gasless Transactions Getting gas tokens is a major friction point.\ Privax enables **gasless UX** via: * **Permit schemes** (meta-transactions) * **Account Abstraction** * **MEV-based relayers** A **forwarder service** ensures users don’t need to manage or understand gas token mechanics. *** #### πŸ’¬ P2P Messaging & Identity System Privax incorporates a **peer-to-peer encrypted communication layer** and identity framework for: * Invoices * Travel Rule compliance * Payment metadata exchange > πŸ”’ Ensures that all sensitive user data is securely shared between parties only. *** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://privax-1.gitbook.io/privax-protocol/how-we-address-them.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
