Architecture
The Ultimate Stopping Dust ($USD) architecture is designed to be modular, transparent, and secure — enabling seamless interaction between users, smart contracts, and decentralized liquidity networks on the BNB Smart Chain (BSC).
It is composed of three main layers: Frontend Layer, Smart Contract Layer, and Backend Integration Layer, all working together to power the dust-cleaning and reward system.
1. Frontend Layer (User Interface)
The frontend is the user-facing DApp where wallet connections, dust scans, and transactions occur. It is built with modern Web3 standards to ensure a fast and intuitive experience.
Core Stack
Framework: Next.js / React
Wallet Integration: Web3Modal / WalletConnect / MetaMask SDK
UI Toolkit: TailwindCSS + Framer Motion (for animation)
Blockchain Library: ethers.js (BNB RPC endpoint)
Functions
Connect wallet securely via MetaMask, TrustWallet, or WalletConnect.
Display detected tokens with balances and liquidity info.
Allow users to choose between Swap to BNB, Swap to $USD, or Burn Mode.
Visualize transaction history and total rewards earned.
✅ Goal: Deliver a user-friendly and trustless interface where all actions are performed directly from the user’s wallet.
2. Smart Contract Layer
At the core of the system are on-chain smart contracts that manage token logic, reflection rewards, swaps, and burns. These contracts are deployed on the BNB Smart Chain (BEP-20) standard for scalability, low fees, and compatibility.
a. Token Contract
Handles all operations related to $USD token economics. Functions include:
Reflection distribution to holders.
Automatic buyback and burn execution.
Transaction tax management (5% fee distribution).
Liquidity pool interaction with PancakeSwap.
Key Variables:
_reflectionFee– 2% distributed to all holders._burnFee– 2% used for buyback & burn._liquidityFee– 1% for automatic LP injection._totalSupply– 1,000,000,000 $USD.
b. Swap Router Contract
The Swap Router integrates directly with PancakeSwap or 1inch APIs to perform token swaps efficiently and safely. It handles:
Price discovery via DEX aggregators.
Gas-optimized routing.
Error handling for failed swaps.
If a token has no liquidity or available pair, the router calls the Burn Contract instead of reverting the transaction.
c. Burn Contract
A minimal, immutable contract that sends non-tradable or dead tokens to a verifiable burn address.
Function: burnToken(address token, uint256 amount)
Tokens sent here are unrecoverable.
Burn events are publicly viewable on BscScan for full transparency.
d. Reward Vault Contract
This vault holds a portion of reflection and buyback funds to ensure consistent rewards for active holders. It distributes $USD or BNB periodically based on holding ratio and activity.
Features:
Claim-on-demand reward system.
Time-based reward distribution window.
DAO-controlled fund release for sustainability.
✅ Goal: Combine all on-chain operations into a verifiable, non-custodial smart contract ecosystem.
3. Backend Integration Layer
While the DApp is primarily decentralized, a lightweight backend layer supports analytics and external API integrations. This layer does not handle funds or private data — it only aggregates public blockchain information.
Components:
Node Provider: BNB RPC (via Ankr / Alchemy / QuickNode)
Data Indexer: The Graph / Covalent / Moralis (for token tracking and analytics)
Notification Engine: Supabase / Firebase (optional alerts for burns, reflections, or rewards)
Cache Layer: Redis (for faster query responses and dashboard stats)
Responsibilities:
Fetch and display dust token lists for UI.
Track total burned tokens, total BNB swapped, and reflections distributed.
Provide data endpoints for dashboards and partner integrations.
Generate real-time “cleanup leaderboard” analytics.
✅ Goal: Deliver off-chain analytics without compromising user privacy or custody.
4. Security & Verification Flow
User connects wallet → signs authorization (non-custodial).
Frontend scans tokens → reads data via blockchain API (read-only).
Smart contract execution → swaps or burns dust tokens.
Transaction receipt → logged on BscScan with proof-of-action.
Reflection trigger → distributes rewards automatically.
Analytics sync → backend updates dashboards & leaderboards.
Security Features:
No wallet keys ever stored.
All contract calls require user signature.
Audited contracts with time-locked functions.
DAO-based permission system for critical actions (buybacks, burns).
✅ Goal: Maintain full decentralization, transparency, and verifiability across every transaction.

6. Architectural Principles
Non-Custodial
Users always retain control of their assets and keys.
Transparency
Every transaction is public and verifiable on-chain.
Automation
The system automates cleaning, swapping, and reward processes.
Security
Independent audits, multisig treasury, and DAO controls.
Scalability
Modular design allows easy expansion to other EVM chains.
7. Scalability & Future Integration
The $USD architecture is chain-agnostic and designed for future multi-chain expansion:
BNB Chain (Main deployment)
Ethereum / Base / Arbitrum (Future bridges)
Polygon / Avalanche / Linea (Optional support)
Future upgrades will integrate:
Cross-chain dust cleaning (via LayerZero / Axelar)
AI-assisted scanning (detect fake or spam tokens)
Mobile SDK for wallet providers
✅ Goal: Build a scalable and interoperable infrastructure capable of handling millions of wallet scans and automated cleanups across multiple networks.
