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.
