Problem

Service providers, freelancers, and small businesses often struggle to:

  • Collect structured client information (quotes, offers, requests) quickly and reliably
  • Manage payments securely without relying on centralized escrow or third-party platforms
  • Verify approvals, deposits, or milestone completion in a trustless, transparent way
  • Handle authentication and identity verification without complex account setups

Payment platforms exist however they often charge high fees (2.9%-10%+ per transaction), centralize trust, and require complex account setups and subscription plans.

This friction leads to slower response times, missed opportunities, and disputes between clients and service providers.

Solution

OpenQuote provides a one-click, decentralized form + payment system for service providers and clients. Here's the typical user journey:

Unique Value Propositions

  • Zero Account Friction: Connect via wallet in seconds using Dynamic. No usernames, passwords, or email verification.
  • Trustless Payment Escrow: Payments are locked in smart contracts on-chain. Automated release or refund based on completion status—no intermediaries.
  • Transparent Workflow: Every step (submission → offer → completion) is recorded on-chain, creating immutable audit trails.
  • Custom Contract Logic: Service providers can define their own terms, milestones, and payment conditions without coding.
  • MNEE-Powered: Built on the MNEE network for fast, low-cost transactions with immediate finality.
  • Client-Friendly Onboarding: Clients don't need crypto experience—they just fill a form and confirm payment.
  • AI-Ready Integration: Built for AI validation of requests, automated offer generation, and smart matching (future).

How it works (step-by-step):

  1. Connect wallet via Dynamic → authenticate client/pro
  2. Client submits service request form (optionally AI-assisted validation)
  3. Smart contract is deployed via Hardhat → MNEE payment deposited
  4. Service provider reviews request (optionally AI-assisted offer generation)
  5. Provider marks as complete or rejects → contract releases or refunds payment on chain.
  6. Optional: ENS, NFT receipt, and document verification for enhanced trust

Environment Variables

Create a .env file in the root directory with the following configuration:

# Network Configuration
# Set the network to mainnet or sepolia
NEXT_PUBLIC_NETWORK=mainnet

# Dynamic Labs Configuration
# Your Environment ID for wallet connection and authentication
NEXT_PUBLIC_DYNAMIC_ENV_ID=

# MNEE Token Configuration
# Address of the MNEE token contract used for payments
MNEE_TOKEN_ADDRESS=0x8ccedbAe4916b79da7F3F612EfB2EB93A2bFD6cF

Environment Variable Details

Variable Purpose Example
NEXT_PUBLIC_NETWORK Specifies the blockchain network (mainnet or sepolia) mainnet
NEXT_PUBLIC_DYNAMIC_ENV_ID Dynamic Labs environment ID for wallet authentication 24d67627-bda8-4945-80ec-5a960988ed1a
MNEE_TOKEN_ADDRESS Contract address of the MNEE token used for transaction payments 0x8ccedbAe4916b79da7F3F612EfB2EB93A2bFD6cF

Usage Quick Reference

Command Description
yarn build Compile all smart contracts and generate artifacts
yarn apply Copy contract ABIs and types to the frontend app for integration
yarn test Run all contract and integration tests (JS/TS and Solidity)
yarn deploy:openquote:local Deploy OpenQuote contracts to a local Hardhat node
npx hardhat ignition deploy --network sepolia ignition/modules/OpenQuote.ts Deploy OpenQuote contracts to Ethereum mainnet using Ignition

Future Business Model

Revenue Stream Description
Transaction Fees 0.5-1% fee on contract creation (much lower than Upwork/Fiverr)
Premium Features Analytics, branding, support, bulk tools
Payment Processing 0.25% fee on invoices or high-value transactions
Value-Added Services Legal templates, dispute resolution, insurance, integrations
Data Insights & Analytics Market insights, benchmarking, ads

Why this model?

  • Lower fees and more transparency than traditional platforms
  • Recurring revenue from SaaS features and B2B analytics
  • Value-added services create new business opportunities

Potential Future Work

  • AI-Powered Request Matching & Recommendations: Implement ML models to automatically match service requests to qualified providers, suggest pricing, and auto-generate contract terms based on service type and client history.
  • Dispute Resolution & On-chain Arbitration: Integrate decentralized arbitration protocol (e.g., Kleros) for smart handling of disagreements, with multi-sig escrow release and appeal mechanisms.
  • NFT Receipts & Reputation System: Issue NFT receipts for completed contracts, build on-chain reputation scores based on completion history, and enable portable credentials for service providers across platforms.
