# Solana Ecosystem Auto-Updating Report
A Python 3 standard-library-only report generator that creates an interactive dark HTML dashboard, a human-readable Markdown report, and a machine-readable JSON report for the Solana ecosystem. No API keys or external Python dependencies are required.
## Data sources
- Solana JSON-RPC (`https://api.mainnet-beta.solana.com`): `getHealth`, `getSlot`, `getEpochInfo`, `getRecentPerformanceSamples`, `getVoteAccounts`, `getSupply`, `getBlockTime`
- CoinGecko simple price API: SOL price, 24h change, 24h volume, market cap
- DefiLlama: chain TVL, DEX daily volume, stablecoin circulating supply
## Metrics
- Network performance: current TPS, average/max TPS over recent performance samples, current/average slot time in ms
- TPS anomaly detection: compares the latest sample against the median of the last 120 samples and flags `spike`, `drop`, or `normal`
- Epoch progress: epoch number, slot index, slots in epoch, block height, transaction count, epoch progress %
- Validators: active and delinquent counts, total activated stake, delinquency rate, top 10 validators by stake with commission
- Supply: total, circulating, and non-circulating SOL
- Market & ecosystem: SOL price/volume/market cap, DefiLlama TVL, DEX 24h volume, Solana stablecoin supply
## Run
```bash
python3 generate.py
```
Outputs are written to `public/index.html`, `public/report.json`, and `public/report.md`.
To serve the live dashboard:
```bash
cd public && python3 -m http.server 8080 --bind 0.0.0.0
```
## Automation
A cron entry regenerates the report every 5 minutes:
```cron
*/5 * * * * /usr/bin/python3 /home/ubuntu/solana-report/generate.py >> /home/ubuntu/solana-report/cron.log 2>&1
```
## Interpretation
- A `tps_anomaly` value of `spike` or `drop` indicates the latest sample is more than 35% away from the recent median.
- A rising delinquency rate or falling average slot time may indicate network stress.
- DEX volume and TVL are provided for economic context.
