Quick Start

Backend (Soroban Contract + Indexer)

# Deploy contract (Soroban CLI)
soroban contract deploy --wasm target/*.wasm --source dev --network testnet

# Run indexer
cd indexer
cargo run

Frontend (SvelteKit UI)

cd client
pnpm install
pnpm dev    # http://localhost:5173

Test Funding: Visit /trades/1 → Fund Trade → Review preview → Approve USDC → Confirm

Contract Functions

Key funding flow:

• get_funding_preview(trade_id, buyer) → FundingPreview (balance, allowance)
• execute_fund(trade_id, buyer, preview) → transfers USDC, emits funded

Analytics

Query on-chain trade metrics (volume, success rate, unique addresses, time windows) via analytics_query. See docs/analytics.md for full details.

Architecture

- `contract/` → Soroban WASM contract
- `indexer/` → Event monitoring + API/WebSocket  
- `client/` → SvelteKit UI (funding interface #32)

## Development

pnpm dev # Frontend cargo test # Backend tests docker-compose up # Indexer + DB

## Smart Contract Testing

The Soroban contract now has dedicated suites for edge cases, security scenarios, integration flows, stress tests, and performance benchmarks under `contract/tests/`.

```bash
npm run test:contract
npm run test:contract:edge
npm run test:contract:security
npm run test:contract:integration
npm run test:contract:performance
npm run test:contract:stress
npm run test:contract:coverage
