SecureTrade Platform: End-to-End Flow Steps
Executive Summary
This document outlines the core user journeys within the SecureTrade ecosystem, demonstrating the interaction between Traders (Buyers/Sellers), Underwriters, and the Governance/Admin layer. It highlights the seamless integration of secure identity (Private SAFE), credit management, and the proprietary PayPledge™ execution flow.
Phase 1: User Onboarding & Authentication
Actor: Buyer
The journey begins with a secure, invite-only onboarding process ensuring all participants are verified and provisioned with the necessary on-chain infrastructure.
1.1 Invitation & Account Creation
Pre-requisite: The Platform Admin invites the Buyer, creating their account and pre-funding it with initial ETH (for gas) and TRADE-S (stablecoin) tokens.
1.2 Secure Login
The user accesses the platform via a secure, passwordless email authentication flow.
Step 1: The Buyer enters their registered email address. 
Step 2: The system requests a One-Time Password (OTP) sent to the user's email. 
1.3 Automated Infrastructure Provisioning
Upon successful authentication, the "Onboarding" process triggers. This critical phase takes approximately 3 minutes and handles complex background operations:
- Deployment of user-specific smart contracts.
- Generation of the Private SAFE (for private network operations).
- Generation of the Public Safe (for Optimism network operations).
1.4 The Trader Dashboard
Once onboarded, the Buyer is directed to the main Dashboard. This command center provides a real-time overview of their financial standing.
Key Elements to Observe:
- Active Purchases & Sales: Summary of ongoing trades.
- Payables & Receivables: Financial obligations and expected incoming funds.
Phase 2: Credit Facility Establishment
Actors: Buyer, Underwriter, Admin
Before trading, the Buyer establishes a credit line to facilitate PayPledge issuance.
2.1 Initiating a Credit Request (Buyer)
The Buyer navigates to the Credit Requests module to seek financing.
Step 1: Navigate to the Credit Requests list page. 
Step 2: Click "Request Credit" to open the application modal. Step 3: The Buyer selects the Credit Source (e.g., specific Underwriter or Marketplace), enters the requested Amount, and provides a Description. Step 4: Submit the request.
2.2 Underwriter Onboarding & Funding (Underwriter)
Note: The Underwriter undergoes the same rigorous onboarding process as the Buyer (Steps 1.2 - 1.3).
Upon accessing their Dashboard, the Underwriter first ensures they have sufficient liquidity (TRADE-S) to service credit lines.
Step 1: From the Dashboard, click "Request TRADE-S". Step 2: Fill in the description in the modal and submit the request to the Admin.
System Action: The Admin reviews and approves the request, dispensing TRADE-S to the Underwriter's wallet.
2.3 Issuing the Credit Line (Underwriter)
With funds available, the Underwriter processes the Buyer's request.
Step 1: Navigate to the Credit Lines page to view incoming requests. 
Step 2: Select the Buyer's request to review details. Step 3: The Underwriter issues the credit line. They have the discretion to approve the full amount or modify it before submitting.
2.4 Credit Verification (Buyer)
The Buyer confirms receipt of the credit line, which appears as TRADE-P (Pledge Credits) and tokens locked in their Collateral Vault.
Step 1: Navigate to the Account/Wallet page. Step 2: Verify the updated balances for TRADE-P and Vault assets.
