The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## 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 ```json { "issuers": ["Lido", "Rocket Pool"], "alertPegDeviationPct": 0.5, "telegramBotToken": "...", "telegramChatId": "..." } ```` #### Example: Full LST/LRT sweep ```json {"alertPegDeviationPct": 1.0} ``` *** ### Output ```json { "symbol": "stETH", "issuer": "Lido", "category": "LST", "contract": "0xae7ab96520de3a18e5e111b5eaab095312d7fe84", "supply_native": 8881877.31, "price_usd": 3920.45, "eth_price_usd": 3924.01, "peg_vs_eth_pct": -0.09, "tvl_usd": 15612345678, "apy_pct": 2.513, "apy_base_pct": 2.513, "apy_reward_pct": null, "defillama_pool_id": "ae6e2c61-..." } ``` 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. *** ### Related Actors - **[EigenLayer Restaking Tracker](https://apify.com/gochujang/eigenlayer-restaking-tracker)** — Covers LRT TVL trends across the restaking landscape. - **[DeFi Yield Scanner](https://apify.com/gochujang/defi-yield-scanner)** — Compare LST yield against general DeFi opportunities. - **[Stablecoin Depeg Monitor](https://apify.com/gochujang/stablecoin-depeg-monitor)** — The other major depeg-risk corner of DeFi. *** *** ### 🎬 Live Sample Run A real run of this actor with default-ish inputs, executed on 2026-06-10: | Field | Value | |---|---| | Items in dataset | 11 | | Dataset (JSON) | `https://api.apify.com/v2/datasets/lVmg14rxEwXL8o4Xm/items?clean=1&format=json` | | Dataset (CSV) | `https://api.apify.com/v2/datasets/lVmg14rxEwXL8o4Xm/items?clean=1&format=csv` | | Run summary (KVS) | `https://api.apify.com/v2/key-value-stores/LsRudLNT7CGPtF2OG/records/SUMMARY` | | Run details | `https://api.apify.com/v2/actor-runs/ZtRqvhbm0NTzlXIdN` | **Try it now**: pop any of the dataset URLs in your browser to see live output, or hit the API endpoints from your code. > Want to reproduce?
