## What it shows

- Stablecoins (USDT, USDC, DAI, USDS, USDe, PYUSD, FDUSD, FRAX, crvUSD, GHO, TUSD, RLUSD, USD1, LUSD, USD0, BOLD):
  - Price: the best $10,000 sale into USDC across the Curve and Uniswap v3 pools checked, fees included. USDC is the reference; its row shows what one USDC buys in USDT.
  - Status: within 30 bps of $1 = holding, 30-100 bps = watch, 100 bps or more = depeg.
  - Depth: how much less per coin a $1M sale gets in the same pools.
  - Supply: the token contract's total supply on Ethereum now and 1, 7 and 30 days ago (Ethereum only, not all chains).
- Yields:
  - Lending: Aave v3, Spark and Compound v3 stablecoin markets. Current supply APY (compounded per second), the rate 30 days ago, deposits, utilization (borrowed / supplied) and liquidity free to withdraw.
  - Savings vaults (ERC-4626): sUSDS, sDAI, sUSDe, scrvUSD, syrupUSDC, sfrxUSD, sUSDf. APY is realized: the share-price change over 7 and 30 days, annualized.
  - Compare up to four markets and project earnings on a deposit at today's rate.
- Pool screener: load a yields list (JSON with data[] of pools: chain, project, symbol, tvlUsd, apy, apyBase, apyReward, apyMean30d, stablecoin, ilRisk, exposure, outlier) and/or a stablecoin list (peggedAssets[] with circulating and price). Filter by chain, project, token, deposits, APY range, stablecoins only, no impermanent loss, single token, outliers. Files are read in the browser and never uploaded. A made-up demo set is bundled.

## Risk notes (fixed rules)

- Lending: utilization 95%+ (high), 90%+ (medium), fully borrowed a day ago, APY more than doubled in 7 days, market under $10M, the coin itself off peg.
- Vaults: share price fell over 7 days, 7-day pace well under the 30-day pace, deposits down 15%+ in 7 days, plus a fixed note on where the yield comes from.
- Pools: outlier APY, APY of 100%+, rewards over half the APY, APY over twice its 30-day average, under $1M deposited, impermanent-loss exposure.

## Data and cost

- Live data: read-only eth_call requests to public Ethereum nodes (PublicNode, dRPC) through the app's server function. No key, no transaction, nothing stored.
- The example snapshot (real chain data from a past block) and the pool screener need no account. Loading live data needs a free SkillSafe sign-in and uses no credits.
- Not financial advice. Smart contracts can fail, stablecoins can lose their peg and yields change every block.
