Transparency in DeFi Data Analytics
DeFiStar.io does not rely on third-party aggregators. We perform direct Remote Procedure Calls (RPC) to the blockchain nodes for over 9 networks. This ensures the yield and TVL you see are not cached or delayed.
Using the eth_call method, we query smart contracts directly to retrieve raw hexadecimal data, which our engine decodes into usable financial metrics. For example, to calculate liquidity in Compound V3:
// RPC Logic from the data fetcher
$totalBorrowHex = rpcCall($rpcUrl, 'eth_call', [
['to' => $cometAddr, 'data' => '0x30648c6a'], 'latest'
]);
$totalBorrow = hexToDec($totalBorrowHex);Once we have the raw "State" of the blockchain, our specialised modules perform the following calculations:
Calculated in money-flow.php by comparing 24-hour TVL changes against a 7-day historical rolling average to identify organic vs. inorganic capital shifts.
Derived in defi-base-rate.php by calculating the TVL-weighted average yield across blue-chip protocols (Aave, Compound, Spark) to establish a "Risk-Free" benchmark.
Our liquidity-stress-gauge.php calculates the ratio of Total Borrowed / Total Supplied. Ratios exceeding 90% trigger an immediate safety warning.
Our market-sentiment.php module uses Least Squares Linear Regression on 48-hour snapshots to project market growth trends.
Our safety.php and risk-radar.php modules work in tandem to audit protocol safety. The Safety Score (0-100) is a weighted calculation:
| Component | Weight | Factor Scrutinised |
|---|---|---|
| Asset Strength | 40% | Blue-chip stablecoins (USDC, USDT, DAI) score highest. Peg history and collateral quality assessed. |
| Protocol Trust | 40% | Established protocols (Aave, Compound, Maker) with audit history and time in market score highest. |
| Chain Security | 20% | Ethereum scores highest (100), followed by major L2s (Arbitrum, Base, Optimism ~85-88). |
Penalties: Points are deducted for TVL under $1M, utilisation "Kinks," or yield anomalies where APY is >15% without clear incentive justification.
The accuracy of our predictive models and trend analysis depends on historical data depth. Below is our current data archive per protocol:
In stablecoin-analytics.php, we don't just show prices. We verify stablecoin health using Price Oracles directly on-chain. This ensures that de-pegging events are detected at the oracle level—the same level used by protocols for liquidations.
