Liquid Staking ETH Health Tracker

Live state of every major Ethereum LST: stETH, wstETH, rETH, cbETH, frxETH, sfrxETH, ETHx, weETH, swETH, ezETH. Supply, APY, USD price, peg vs ETH, and Lido's withdrawal-queue ETH balance. Telegram depeg alerts. No API key required.

What It Does

Liquid staking is now a >$25B market — and the most-watched risk in DeFi after stablecoins. This Actor returns, for each tracked LST:

• Current on-chain supply (Etherscan tokensupply)
• Live APY + base + reward (DefiLlama yields)
• TVL in USD (DefiLlama)
• Live USD price (Coingecko)
• Peg vs ETH % (key depeg early-warning)
• Issuer label (Lido, Rocket Pool, Coinbase, Frax, Stader, ether.fi, Swell, Renzo)
• Category (LST vs LRT)

Plus an optional row for Lido's WithdrawalQueueERC721 ETH balance — the contract-held ETH waiting to be redeemed. Sustained queue growth = Lido unstake pressure.

---

Why This Matters

• 2022 stETH depeg flashbacks: stETH traded at -8% during the Celsius/3AC unwind. The first 1% depeg signal would have been worth millions to anyone watching this number. This Actor monitors it.
• LRT depegs (ezETH, weETH) cascade fast. Restaking adds slashing risk on top of staking risk — peg matters more, not less.
• Lido queue length correlates with macro deleveraging events (LST holders rushing the exit during ETH dumps).

Input

Field	Type	Default	Description
issuers	array	all	Subset of Lido, Rocket Pool, Coinbase, Frax, Stader, ether.fi, Swell, Renzo
includeWithdrawQueue	boolean	true	Add a Lido withdraw-queue ETH balance row
alertPegDeviationPct	number	0	Telegram alert if any LST trades > X% below ETH. 0 = off
telegramBotToken	string (secret)	—	Bot token
telegramChatId	string	—	Chat ID

Example: Lido + Rocket Pool only with depeg alert

{
  "issuers": ["Lido", "Rocket Pool"],
  "alertPegDeviationPct": 0.5,
  "telegramBotToken": "...",
  "telegramChatId": "..."
}

Example: Full LST/LRT sweep

{"alertPegDeviationPct": 1.0}

Plus a SUMMARY with total TVL, depeg list, and Lido queue ETH balance.

Pricing

• $0.002 per LST returned (slightly higher due to multiple data sources per row)

Examples:

• Full sweep (~10 LSTs + queue): $0.022
• Lido-only: $0.004

---

Use Cases

Depeg early-warning — Schedule every 10 minutes with alertPegDeviationPct: 0.5. Catch unwinds the moment they start.

LST APY arbitrage scanner — Compare APY across issuers. When rETH APY beats stETH by 1%+ for sustained periods, capital flows shift.

Lido queue stress monitor — Track the queue ETH balance as a daily metric. Spikes correlate with risk-off events.

---

Data Sources

• DefiLlama /yields/pools (TVL + APY per pool)
• Etherscan V2 tokensupply + balance for the Lido queue
• Coingecko simple/price for USD pricing
• No API key required (Etherscan key bundled)

---

Limitations

• Ethereum mainnet only.
• Peg is computed against ETH spot from Coingecko — not from any specific DEX pool. Pool-level peg can differ slightly during illiquid moments.
• Lido withdraw queue balance is a proxy, not a precise queue-length signal. The contract balance includes already-finalized + unclaimed withdrawals.
