The problem it solves # Vouch: Decentralized Escrow Infrastructure for Social Commerce ## The Problem Vouch Solves Social commerce in Southeast Asia happens inside private chats — Instagram DMs, WhatsApp, Facebook and TikTok messages. However, these platforms were never designed for secure transactions. As a result: - Buyers are afraid to pay first - Sellers are afraid to ship first - Scams are common and difficult to resolve - Existing solutions force users into centralized marketplaces with high fees and lock-in - There is no neutral, trustless escrow layer for transactions that happen directly inside chats ## What is Vouch? Vouch is a decentralized escrow infrastructure for social commerce, built on the Lisk network. Vouch turns a simple payment link into an on-chain escrow contract that securely holds funds until both buyer and seller fulfill their obligations. Without becoming a marketplace, Vouch brings marketplace-level trust to Instagram, WhatsApp, and TikTok transactions — directly inside DMs. ## Who Can Use Vouch? Vouch is designed for real people doing real social commerce, including: - Instagram sellers - WhatsApp merchants - TikTok live sellers - Individual resellers and small businesses **No blockchain knowledge is required. No account registration is needed. If you can send a link, you can use Vouch.** ## Use Cases Vouch focuses on one core use case done extremely well: **Secure DM-Based Transactions** - Selling physical goods via Instagram or WhatsApp - High-trust transactions between strangers - One-off sales without marketplace onboarding *Future extensions may include digital goods and service escrow, but the current focus is simple, secure social commerce payments.* ## How Vouch Makes Transactions Safer ### Decentralized Escrow Protection - **Smart Contract Escrow**: All funds are locked in a Lisk smart contract - **Non-Custodial**: No backend or company can steal or freeze funds - **Automatic Release**: Funds are released only when conditions are met - **Timeout Enforcement**: Auto-release or auto-refund if a party is inactive The smart contract — not the backend — is the final authority. ### On-Chain Identity & Transparency - **Wallet = Identity**: Sellers and buyers are identified by their wallets - **Immutable Escrow History**: All escrow events are recorded on-chain - **Public Verification**: Anyone can verify escrow status independently - **No Impersonation**: Sellers must sign escrow creation on-chain ### Hybrid Fiat + Crypto Safety - **Crypto Payments**: USDC or IDRX Lisk, fully on-chain - **Fiat Payments**: QRIS / VA via Xendit - **Unified Escrow Logic**: Regardless of payment method, escrow rules remain on-chain - **Oracle-Style Backend**: Backend only verifies fiat payments, never controls funds ## How Vouch Makes Transactions Easier ### Web2-Friendly User Experience - No login - No registration - Mobile-first interface - Familiar payment language - Clean, non-crypto UI Users interact with Vouch the same way they already sell online — through chats. ### Simple, Shareable Flow 1. Seller creates escrow link 2. Pastes link into DM 3. Buyer pays 4. Seller ships 5. Buyer confirms 6. Funds are released **No extra apps. No marketplace onboarding. No platform lock-in.** ### Flexible Payment Methods - Pay with USDC and IDRX on Lisk - Pay with QRIS / Virtual Account - Supports local payment behavior in Southeast Asia - One escrow flow for all payment types ## Why Blockchain is Essential Vouch does not use blockchain as a buzzword. Blockchain is required because: - Escrow rules must be neutral - Funds must be non-custodial - Outcomes must be deterministic - Trust must not rely on a company or backend *If the backend disappears, escrow funds remain safe on-chain.* ## Final Statement Vouch does not try to replace marketplaces. It replaces the missing trust layer in social commerce — where millions of transactions already happen every day. **Trust your DMs.**
