Overview
Client: Vouch App Inc. (“Vouch”) – A Web3-powered platform redefining freelance collaboration with a referral-first model.
Industry: Freelance Marketplace, Web3
Engagement Type: Feature Implementation & Blockchain Integration
Status: Beta testing on Optimism testnet
Vouch’s mission is to transform how freelance work happens by connecting employers (Requester), workers (Vouchees), and trusted referrers (Vouchers) in a secure, trust-enabled ecosystem. Their unique model minimizes friction, incentivizes network utilization, and streamlines payment processes. Spawn Solutions joined Vouch to integrate blockchain capabilities into their platform, ensuring secure, transparent, and automated transactions powered by smart contracts.
The Challenge
Vouch identified several challenges in today’s freelance and gig economy that their platform aimed to solve:
- Disconnected Networks: Current platforms lack tools to help users leverage their personal networks effectively for meaningful connections and opportunities.
- Payment and Trust Issues: Freelancers and employers often face disputes, miscommunication, and delayed payments.
- Lack of Incentives: Existing platforms fail to reward users for making high-value referrals and contributions to their networks.
- Limited Transparency: Peer-to-peer transactions often lack accountability and verification tied to specific work outcomes.
- Complex Blockchain Onboarding: Blockchain features are traditionally challenging for non-crypto-native users.
Vouch had a working frontend and application framework but lacked the critical blockchain integration to underpin their innovative model. Their requirements included:
- Escrow Contract Logic: Lock and release funds securely based on predefined conditions and gig states.
- State Management: Transition gigs between various states based on user actions and timelines (e.g., gig completion, cancellation).
- Gasless UX: Simplify the blockchain experience for non-native users by abstracting wallet management and gas fees.
- Seamless Integration: Ensure that all blockchain-related functionality seamlessly integrated with their existing UI.
- Regulatory Constraints: Address challenges with blockchain use in the U.S., particularly in states like New York where regulations are stringent.
The Solution
Spawn Solutions stepped in to integrate blockchain functionality into the Vouch platform, focusing on business logic, security, and user-friendliness.
Smart Contract Development
- Built a robust escrow contract using Solidity on the Optimism blockchain.
- Designed contracts to lock employer funds securely during gig creation, ensuring payment is released only when specific conditions are met (e.g., gig completion or arbitration outcomes).
State Machine Logic
- Developed a state machine to track the gig lifecycle, from creation to completion or dispute resolution.
- Enabled automated transitions between states based on user actions and timelines, such as:
- Gig Created: Funds are locked in the smart contract.
- In Progress: Work has started, and milestones are tracked.
- Completed: Employer approves the work and releases payments.
- Disputed: Arbitration resolves disagreements over deliverables.
- Cancelled: Funds are returned if the employer cancels within the defined period.
Gasless UX for Mainstream Adoption
- Implemented Abstracted wallet management to improve accessibility for non-crypto-native users.
- Eliminated the need for users to handle gas fees, with the platform managing all transaction costs in the background.
Business Logic-Driven Architecture
- Tailored the smart contract to reflect complex business rules, such as:
- Referral bonuses for Vouchers.
- Fair fund allocation among the platform, Voucher, and Vouchee.
- Automatic fund release after defined timelines or arbitration outcomes.
Technologies Used
- Blockchain: Optimism (Layer 2 Ethereum scaling solution).
- Smart Contracts: Solidity for contract logic.
- Testing: Hardhat and JavaScript for rigorous smart contract testing.
- Library: Ethers.js for blockchain interactions.
