+# SkillSphere — Open-Source GitHub Issues & SCF Submission Roadmap
+
+This document serves as the comprehensive open-source contributor guide, issue directory, and Stellar Community Fund (SCF) roadmap for **SkillSphere** — a decentralized, peer-to-peer knowledge marketplace with real-time per-second streaming payments powered by Stellar and Soroban smart contracts.
+
+---
+
+## 🏛️ 1. Project Architecture & Integration Flow
+
+SkillSphere consists of three core open-source repositories designed for seamless interaction:
+
+```
++-----------------------------------------------------------------------------------+
+|                                SkillSphere-Dapp                                   |
+|       (Next.js 15 App Router, React 19, TailwindCSS, @stellar/freighter-api)      |
++----------------------------------------+------------------------------------------+
+                                         |
+               +-------------------------+-------------------------+
+               |                                                   |
+               v                                                   v
++----------------------------------------+        +----------------------------------+
+|          SkillSphere (Backend)         |        |      SkillSphere-Contracts       |
+| (Node.js/TS, Express, Apollo GraphQL,  |        | (Rust + Soroban Smart Contracts: |
+|  Prisma PostgreSQL, Event Indexer)     |        |  Vault, Reputation, Calendar, ID)|
++----------------------------------------+        +----------------------------------+
+```
+
+### Component Roles:
+1. **`SkillSphere-Contracts`**: Soroban smart contracts handling trustless escrow lockup, continuous per-second value release, instant refunds, on-chain user identity registration, and immutable reputation scoring.
+2. **`SkillSphere` (Backend)**: Off-chain auxiliary service that indexes Soroban RPC event logs into PostgreSQL, powers full-text expert search, and provides WebRTC signaling for video consultations.
+3. **`SkillSphere-Dapp` (Frontend)**: Web application providing expert discovery, wallet connection, session booking, WebRTC video calling with live per-second payment timer overlays, and transaction tracking.
+
+---
+
+## ⚡ 2. Wallet Connection & Network Alignment (Testnet & Mainnet)
+
+The dApp frontend (`SkillSphere-Dapp`) is integrated with `@stellar/freighter-api` via [`WalletProvider.tsx`](file:///c:/Users/TOSHIBA/Documents/SkillSphere-Dapp/src/providers/WalletProvider.tsx).
+
+### Key Integration Highlights:
+- **Freighter Wallet Integration**: Connects directly to Freighter browser extension to retrieve public key addresses (`G...`) without requiring central accounts or password storage.
+- **Network Polling & Auto-Detection**: Continuously polls Freighter network state every 3 seconds to determine active network (`TESTNET`, `PUBLIC` / Mainnet, `FUTURENET`).
+- **Horizon XLM Balance Sync**: Connects to official Horizon RPC nodes (`https://horizon-testnet.stellar.org` & `https://horizon.stellar.org`) to fetch live native account balances.
+- **Network Mismatch Warning Banner**: Displays an alert banner on top of the UI whenever a user's Freighter network is set differently than the application environment (e.g. prompt to switch from Mainnet to Testnet).
+- **Sandbox Mock Switcher**: Includes a built-in sandbox mock profile toggle ([`DevToolsSwitcher.tsx`](file:///c:/Users/TOSHIBA/Documents/SkillSphere-Dapp/src/components/ui/DevToolsSwitcher.tsx)) allowing open-source contributors and SCF reviewers to test client and expert personas without requiring a live browser extension.
+

+
+## 📋 3. Detailed Open-Source GitHub Issues Directory
+
+Below is a curated set of 10 GitHub issue templates ready for creation across your repositories.
+
+---
+
+### 📜 Category A: `SkillSphere-Contracts` (Rust / Soroban Smart Contracts)
+
+#### **Issue #1: Implement Dynamic Rate-Limit Escrow Locking in `payment-vault-contract`**
+- **Labels**: `enhancement`, `good first issue`, `soroban`, `rust`
+- **Context**: Prevent clients from creating multiple rapid escrow locks for the same session ID due to frontend retries or network latency.
+- **Tasks**:
+  1. Add `min_session_interval` configuration in contract persistent storage.
+  2. Validate that the elapsed time between consecutive escrow locks for a given session ID exceeds `min_session_interval`.
+  3. Emit Soroban event: `EscrowLocked(session_id, client, expert, rate_per_second, total_deposit)`.
+- **Suggested Files**: `contracts/payment-vault-contract/src/contract.rs`, `storage.rs`, `events.rs`
+- **Acceptance Criteria**: Unit tests in `test.rs` confirm rapid duplicate lock calls revert with `Error::RateLimitExceeded`.
+
+---
+
+#### **Issue #2: Add Multi-Asset Token Support (Stellar Asset Contract / USDC) to Escrow Vault**
+- **Labels**: `feature`, `smart-contracts`, `scf-priority`
+- **Context**: Expand the payment vault to accept Stellar Asset Contracts (SAC) such as USDC alongside native XLM.
+- **Tasks**:
+  1. Modify `initialize_session_vault` to accept an asset `Address` parameter.
+  2. Implement cross-contract invocations using `token::Client::new(&env, &token_address).transfer(...)`.
+  3. Support multi-token streaming rate calculations based on asset decimal precision.
+- **Suggested Files**: `contracts/payment-vault-contract/src/contract.rs`, `types.rs`
+- **Acceptance Criteria**: Integration test demonstrates depositing and streaming custom Stellar tokens (e.g., testnet USDC).
+
+---
+
+#### **Issue #3: Automated Dispute Penalty Slashing in `reputation-scoring-contract`**
+- **Labels**: `feature`, `security`, `soroban`
+- **Context**: When a dispute is resolved in favor of the client, expert reputation scores should automatically decrease based on dispute severity.
+- **Tasks**:
+  1. Add `penalize_expert(expert: Address, penalty_points: u32)` function restricted to authorized dispute arbitrator contracts.
+  2. Update expert tier thresholds (`ExpertTier::Verified`, `ExpertTier::TopRated`, `ExpertTier::Suspended`).
+  3. Emit event `ReputationPenalized(expert, penalty_points, new_score)`.
+- **Suggested Files**: `contracts/reputation-scoring-contract/src/contract.rs`, `lib.rs`
+- **Acceptance Criteria**: `cargo test` confirms proper deduction of points and automatic tier demotion.
+
+---
+
+#### **Issue #4: WASM Binary Footprint & Gas Profile Optimization**
+- **Labels**: `performance`, `ci/cd`, `rust`
+- **Context**: Optimize compiled Soroban WASM binaries to minimize transaction footprint and gas execution costs on Stellar mainnet.
+- **Tasks**:
+  1. Configure release profile options in root `Cargo.toml` (`opt-level = "z"`, `codegen-units = 1`, `panic = "abort"`).
+  2. Profile gas usage using `soroban-cli` contract invocation metrics.
+- **Suggested Files**: `Cargo.toml`, `.github/workflows/ci.yml`
+- **Acceptance Criteria**: Reduced WASM file size below 50KB per contract module.
+
+---
+
+### ⚙️ Category B: `SkillSphere` (Backend & Indexer API)
+
+#### **Issue #5: Soroban Event Stream Consumer for Real-Time Payment Indexing**
+- **Labels**: `feature`, `backend`, `indexer`
+- **Context**: Index contract events from Stellar RPC into PostgreSQL so expert earnings and session histories are queried instantly off-chain.
+- **Tasks**:
+  1. Create a Stellar RPC event poller in `backend/src/indexer.ts` fetching `getEvents` filtered by contract ID.
+  2. Decode Soroban XDR event topics and data into TypeScript objects.
+  3. Save transactions and update session status in PostgreSQL via Prisma.
+- **Suggested Files**: `backend/src/indexer.ts`, `backend/prisma/schema.prisma`
+- **Acceptance Criteria**: Emitted `PaymentStreamed` events update database records within 2 seconds.
+
+---
+
+#### **Issue #6: WebRTC Peer-to-Peer Signaling Server Heartbeat & Disconnect Timeout**
+- **Labels**: `enhancement`, `websockets`, `backend`
+- **Context**: Ensure video call sessions handle sudden peer disconnects gracefully and trigger contract auto-settlement.
+- **Tasks**:
+  1. Add ping/pong heartbeat intervals (10s) in Socket.IO signaling server.
+  2. If a peer drops connection without sending `EndSession`, wait 60 seconds grace period then trigger fallback settlement.
+- **Suggested Files**: `backend/src/socket/signaling.ts`
+- **Acceptance Criteria**: Simulated network disconnect triggers `PeerDisconnected` notification and auto-settlement fallback.
+
+---
+
+#### **Issue #7: GraphQL Subscriptions for Live Consultation Session Status**
+- **Labels**: `enhancement`, `graphql`, `backend`
+- **Context**: Provide live real-time updates to client and expert UI dashboards when session status changes.
+- **Tasks**:
+  1. Define Apollo Server GraphQL subscriptions for `sessionUpdated(sessionId: ID!)`.
+  2. Publish events when indexer detects escrow funding or settlement transactions on-chain.
+- **Suggested Files**: `backend/src/graphql/schema.ts`, `backend/src/graphql/resolvers.ts`
+- **Acceptance Criteria**: Frontend subscription receives real-time payload upon escrow confirmation.
+
+---
+
+### 🎨 Category C: `SkillSphere-Dapp` (Next.js Frontend)
+
+#### **Issue #8: Real-Time Freighter Transaction Signing Stepper for Escrow Lockup**
+- **Labels**: `feature`, `wallet`, `frontend`
+- **Context**: Connect [`FundSessionModal.tsx`](file:///c:/Users/TOSHIBA/Documents/SkillSphere-Dapp/src/components/marketplace/FundSessionModal.tsx) to sign and submit Soroban transactions directly using Freighter.
+- **Tasks**:
+  1. Construct contract call XDR using `@stellar/stellar-sdk` and `useSorobanTx` hook.
+  2. Prompt Freighter signature via `signTransaction()`.
+  3. Show step-by-step progress using [`TxProgressStepper.tsx`](file:///c:/Users/TOSHIBA/Documents/SkillSphere-Dapp/src/components/ui/TxProgressStepper.tsx) (Preparing -> Signing -> Submitting -> Confirmed).
+- **Suggested Files**: `src/components/marketplace/FundSessionModal.tsx`, `src/hooks/useSorobanTx.ts`
+- **Acceptance Criteria**: Successful transaction displays live Stellar Explorer transaction hash link.
+
+---
+
+#### **Issue #9: On-Chain Dispute Resolution & Appeal Submission UI**
+- **Labels**: `feature`, `ui`, `frontend`
+- **Context**: Allow knowledge seekers or experts to submit a dispute claim for reviewed sessions.
+- **Tasks**:
+  1. Create an appeal submission modal using [`AppealForm.tsx`](file:///c:/Users/TOSHIBA/Documents/SkillSphere-Dapp/src/components/session/AppealForm.tsx).
+  2. Upload evidence metadata and invoke `submit_dispute` on the `reputation-scoring-contract`.
+- **Suggested Files**: `src/components/session/AppealForm.tsx`, `src/app/dashboard/support/page.tsx`
+- **Acceptance Criteria**: Submitted disputes appear in the `/admin/disputes` dashboard view.
+
+---
+
+#### **Issue #10: Multi-Currency Exchange Rate Conversion & Live Wallet Switcher**
+- **Labels**: `enhancement`, `ui`, `frontend`
+- **Context**: Display session prices in XLM alongside fiat equivalence (USD, EUR, GBP, JPY) using real-time price feeds.
+- **Tasks**:
+  1. Wire [`useCurrency.ts`](file:///c:/Users/TOSHIBA/Documents/SkillSphere-Dapp/src/hooks/useCurrency.ts) to public exchange rate API.
+  2. Allow instant switching between currencies in [`Navbar.tsx`](file:///c:/Users/TOSHIBA/Documents/SkillSphere-Dapp/src/components/layout/Navbar.tsx).
+- **Suggested Files**: `src/hooks/useCurrency.ts`, `src/components/layout/Navbar.tsx`
+- **Acceptance Criteria**: Toggling currency dropdown updates rates smoothly across expert cards and booking modals.
