About xendune

xendune is a decentralized escrow protocol that brings trustless commerce to Web3. By replacing centralized intermediaries with smart contracts, we enable secure peer-to-peer transactions across borders—no banks, no middlemen, no trust assumptions.

Mission

Build the infrastructure layer for decentralized commerce—where every transaction is transparent, every dispute is resolved fairly, and every merchant is held accountable.

Why xendune

Traditional e-commerce platforms act as trusted intermediaries: they custody buyer funds, control dispute outcomes, and hold merchant reputation. This model has fundamental problems:

• Single point of failure: Platform bankruptcy, hacks, or policy changes can freeze user funds overnight
• Censorship and bans: Merchants can lose years of reputation and income from a single platform decision
• Opaque arbitration: Dispute resolution happens behind closed doors with no verifiable record
• Cross-border friction: International sellers face payment processing delays, forex conversion fees, and regulatory barriers
• Lack of real accountability: Bad merchants get banned at most—no economic consequences

xendune solves these by moving the entire commerce flow on-chain.

How It Works

On-Chain Escrow

When a buyer purchases an item, USDT is locked in a dedicated smart contract—not a company wallet. Funds can only flow through predefined business logic: delivery confirmation, arbitration resolution, or timeout handling. No individual or entity can move the funds otherwise.

Merchant Deposits

Every seller can stake USDT (500–1,000,000) as collateral. If the seller loses arbitration, the buyer is compensated directly from this deposit. This creates real economic skin in the game—not just a star rating. The deposit also serves as the entry threshold for becoming a community arbitrator (≥ 1,000 USDT).

Transparent Arbitration

All disputes are adjudicated by community arbitrators randomly selected on-chain (up to 13 per case), who must stake ≥ 1,000 USDT and pass a cooldown period to participate. Every arbitration decision, compensation amount, and fund flow is recorded on-chain with a full audit trail.

Stablecoin Settlement

All transactions settle in USDT, eliminating forex risk and enabling instant cross-border payments. No bank accounts, no payment processors, no chargeback disputes.

What You Can Do on xendune

Buy and Sell Products

Four product types, each with tailored escrow flows:

• Physical goods (3%) — logistics tracking and auto-confirm deadlines
• Virtual goods (3%) — instant digital delivery with buyer confirmation
• Local services (5%) — geo-based service delivery with completion confirmation
• WantToBuy orders (3%) — buyer posts a demand, seller accepts and fulfills

Timed Auctions

Sell goods in an eBay-style timed auction with anti-snipe extension. 5% fee; sellers must stake a merchant deposit as collateral.

C2C OTC Trading

Peer-to-peer USDT↔fiat exchange with escrow protection. Trade directly with other users—smart contracts custody the USDT until both parties confirm. 0.2% fee.

Shuifang Exchange

Professional exchange merchants post listings executed transparently by escrow contracts.

Earn Referral Rewards

Two-tier referral system automatically distributes rewards on every settlement. Invite sellers to join and earn a share of their transaction fees (L1 gets 20%, L2 gets 10% of the fee portion)—all executed on-chain, all automatic.

Technical Foundation

• 32 smart contracts built with Solidity ^0.8.35, deployable to any EVM-compatible chain
• EIP-1167 minimal proxy pattern reduces deployment costs by ~97%
• Generational archive storage — unlimited history without high-gas array operations
• PlatformFeeSplitter — automatic 3-way fee split; payee addresses locked at deployment
• PlatformSettings address lock — factory contract addresses locked 24 hours after deployment, permanently immutable
• Currently deployed on BNB Smart Chain (BSC)

Core Principles

1. Non-custodial: The protocol never holds user funds in admin-controlled wallets. All funds are in smart contracts with predefined rules.
2. Transparent: Every transaction, arbitration, and fee split is verifiable on-chain.
3. Accountable: Merchant deposits create real economic consequences for dishonest behavior.
4. Permissionless: Anyone can be a buyer. Anyone who posts a deposit can be a seller.
5. Chain-agnostic: Standard EVM contracts with no chain-specific dependencies.
