## <mark style="color:purple;">Glossary</mark>

Key terms and concepts in the Macro ecosystem.

### <mark style="color:purple;">A</mark>

**Address Book**\
Saved list of labeled wallet addresses for quick sending and identification.

**Anonymity Set**\
Number of users in a privacy mixer pool. Larger sets = better privacy.

**API (Application Programming Interface)**\
Set of functions and protocols for building software integrations.

### <mark style="color:purple;">B</mark>

**Buy-Back**\
Protocol purchasing $MACRO from market using ecosystem revenue.

**Burn**\
Permanent removal of tokens from circulation by sending to unrecoverable address.

### <mark style="color:purple;">C</mark>

**Canvas Fingerprinting**\
Tracking technique using HTML5 canvas to uniquely identify browsers. Macro randomizes this.

**Cookie Jar**\
Storage for cookies. Each Privacy Profile has isolated cookie jar.

### <mark style="color:purple;">D</mark>

**dApp (Decentralized Application)**\
Application built on blockchain, usually Ethereum or EVM-compatible chains.

**DeGoogled**\
Chromium browser with all Google services removed.

**DNS over HTTPS (DoH)**\
Encrypts DNS queries to prevent ISP snooping.

### <mark style="color:purple;">E</mark>

**E2EE (End-to-End Encryption)**\
Encryption where only sender and receiver can decrypt messages. Server cannot read content.

**EIP (Ethereum Improvement Proposal)**\
Standards for Ethereum ecosystem. Macro supports EIP-1193, EIP-1102, EIP-712.

**Exit Node**\
VPN node where traffic exits to destination.

### <mark style="color:purple;">F</mark>

**Fingerprinting**\
Tracking technique using browser/device characteristics to identify users. Macro defends against this.

**Flashbots**\
MEV protection service for private transaction submission.

### <mark style="color:purple;">G</mark>

**Gas**\
Fee paid for Ethereum transactions. Measured in gwei.

### <mark style="color:purple;">H</mark>

**Hardware Wallet**\
Physical device for storing crypto keys offline (Ledger, Trezor).

**Hex**\

### <mark style="color:purple;">I</mark>

**Interception**\
Signing Sandbox catching transactions before they're signed.

### <mark style="color:purple;">K</mark>

**Kill Switch**\
Feature that blocks all traffic if VPN disconnects, preventing IP leaks.

### <mark style="color:purple;">L</mark>

**L1 (Layer 1)**\
Base blockchain (Ethereum, BSC, Avalanche).

**L2 (Layer 2)**\
Scaling solution built on top of L1 (Arbitrum, Optimism, Polygon).

### <mark style="color:purple;">M</mark>

**Mesh Network**\
Decentralized network where nodes connect peer-to-peer without central server.

**MEV (Maximal Extractable Value)**\
Profit extracted by reordering/front-running transactions. Macro protects against this.

**Mixer**\
Privacy tool that breaks the link between sender and receiver on-chain.

### <mark style="color:purple;">N</mark>

**Node**\
Computer participating in network. In Macro: VPN nodes that route traffic.

**Node Operator**\
Person/entity running a VPN node. Earns $MACRO for routing traffic.

### <mark style="color:purple;">O</mark>

**Onion Routing**\
Multi-hop encryption where each node only knows previous and next hop.

### <mark style="color:purple;">P</mark>

**Per-dApp Permissions**\
Granular control over what each dApp can access from your wallet.

**Policy Engine**\
Component of Signing Sandbox that checks transactions against user-defined rules.

**Privacy Profile**\
Isolated identity with separate cookies, wallets, and permissions.

### <mark style="color:purple;">R</mark>

**Referrer**\
Information about where you came from when clicking a link. Macro strips this.

**Relay Node**\
Intermediate VPN node that forwards traffic between entry and exit.

**Reputation Score**\
Rating for VPN nodes based on uptime, performance, user feedback.

**RPC (Remote Procedure Call)**\
Communication protocol for interacting with blockchain nodes.

### <mark style="color:purple;">S</mark>

**Seed Phrase**\
12-24 word backup for crypto wallet. Store securely in Zero-Knowledge Vault.

**Signing Sandbox**\
Component that intercepts, translates, and policy-checks all wallet transactions.

**Slippage**\
Difference between expected and actual trade price. Set tolerance in swaps.

### <mark style="color:purple;">T</mark>

**Tab-Aware AI**\
AI that understands page context and processes locally without external calls.

**Telemetry**\
Data about software usage sent to developers. Macro has zero telemetry.

**Testnet**\
Test blockchain for experimenting without real funds (Goerli, Sepolia).

### <mark style="color:purple;">U</mark>

**Unbonding Period**\
Time required to unstake tokens (7-30 days depending on staking type).

**Undrainable**\
Wallet protection where malicious transactions are blocked by Signing Sandbox.

### <mark style="color:purple;">V</mark>

**VPN (Virtual Private Network)**\
Service that routes your internet traffic through remote servers for privacy.

### <mark style="color:purple;">W</mark>

**Watch-Only Wallet**\
Wallet you can monitor without holding private keys.

**WebRTC**\
Real-time communication protocol that can leak IP addresses. Macro blocks by default.

### <mark style="color:purple;">Z</mark>

**Zero-Knowledge Vault**\
Encrypted local storage for sensitive data. Only you can decrypt with your password.

**Zero-Knowledge Proof**\
Cryptographic method to prove something without revealing the information itself. Used in mixer.
