# ETH Staking Tracker (Lido + RocketPool + Beacon Chain) (`gochujang/eth-validator-tracker`) Actor Live Ethereum staking metrics: Lido stETH APR (current + 7d SMA), RocketPool rETH APR + beacon-chain APR, validator count, ETH staked, plus current epoch / finality lag / pending exits from public Beacon API. Telegram alerts on APR drop or finality issues.

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 ## ETH Staking Tracker (Lido + RocketPool + Beacon Chain) > Live Ethereum staking metrics in one row: **Lido stETH APR**, **RocketPool rETH APR**, beacon-chain APR, validator count, ETH staked, plus current epoch / finality lag / pending exits. **No API key required.** --- ### Why this exists If you stake ETH (directly or via LST), three numbers matter every day: 1. **Current APR** — is Lido still paying more than RocketPool? 2. **Network health** — is the chain finalizing? Any congestion? 3. **Queue status** — how long if you exit / enter today? Every paid analytics dashboard (Glassnode, Dune, Rated) charges $30-$500/mo for slices of this. This actor returns it for **$0.002 per snapshot** by combining 3 free public sources. --- ### What you get #### Summary row (one per run) | Field | Example | Notes | |---|---|---| | `lido_apr_pct` | `2.569` | current stETH APR | | `rocketpool_apr_pct` | `2.064` | current rETH APR | | `apr_spread_lido_minus_rp` | `+0.505` | which LST pays more | | `rocketpool_validators` | `973,652` | total RP validators | | `current_epoch` | `463,712` | beacon chain epoch | | `finalized_epoch` | `463,710` | should be ~2 behind | | `finality_lag_epochs` | `2` | network health | | `pending_exits_pool` | `0` | unprocessed voluntary exits | | `eth_price_usd` | `2,387` | spot price | #### Per-source detail rows - `source: lido` — stETH APR (current + 7d SMA + 7d min/max) - `source: rocketpool` — rETH APR + beacon-chain APR + ETH staked + RPL price - `source: beacon` — epoch / slot / finality state / voluntary exit pool --- ### Use cases 1. **LST selection** — Daily check: which LST pays more right now? 2. **Network monitoring** — Alert if finality lag > 4 epochs (chain trouble) 3. **APR forecasting** — 7-day SMA + min/max from Lido lets you smooth noise 4. **Exit timing** — Watch the voluntary exit pool before you queue your own exit 5. **Research** — Trustless, public data source for staking reports / dashboards --- ### Quick start #### Default — full snapshot ```json {} ```` #### Alert on APR drop below 2% ```json { "alertAprBelowPct": 2.0, "telegramBotToken": "YOUR_BOT_TOKEN", "telegramChatId": "YOUR_CHAT_ID" } ``` #### Alert on finality lag (network health) ```json { "alertFinalityLag": 4, "telegramBotToken": "YOUR_BOT_TOKEN", "telegramChatId": "YOUR_CHAT_ID" } ``` *** ### Pricing **Pay-Per-Event**: `$0.002 per row returned.` Each run produces 4 rows (summary + Lido + RocketPool + Beacon detail) = **$0.008 per snapshot**. | Schedule | Daily cost | |---|---| | Once a day | $0.008 | | Every hour | $0.19 | | Every 15 min | $0.77 | vs Rated.Network Pro at $99/mo, you break even at ~30,000 snapshots. *** ### Data sources 1. [Lido stETH APR API](https://docs.lido.fi/contracts/lido-oracle/) — free, public, real-time 2. [RocketPool Stats API](https://rocketpool.net/) — free, public 3. [Ethereum Beacon API](https://ethereum.github.io/beacon-APIs/) via publicnode.com — free, public, no key *** ### Limitations & honest disclosure - **Activation/exit queue length and wait time** require beaconcha.in (now gated). We expose pending voluntary exits from the beacon pool, which is a partial signal — not full queue depth. - **APR** is point-in-time from each protocol's published value, not back-tested historic realized. - For protocol-level back-testing and per-validator analytics, use rated.network's paid API. *** ### Related actors (same author) - [LST Health Tracker](https://apify.com/gochujang/lst-health-tracker) — Peg status across all major LSTs - [EigenLayer Restaking Tracker](https://apify.com/gochujang/eigenlayer-restaking-tracker) - [DeFi Yield APY Scanner](https://apify.com/gochujang/defi-yield-scanner) — Compare LST yields vs DeFi alternatives - [Multi-Chain Gas Tracker](https://apify.com/gochujang/multichain-gas-tracker) — Time your stake/unstake transactions *** *** ### 🎬 Live Sample Run A real run of this actor with default-ish inputs, executed on 2026-06-10: | Field | Value | |---|---| | Items in dataset | 4 | | Dataset (JSON) | `https://api.apify.com/v2/datasets/8bHR9g6W6rweGrGyI/items?clean=1&format=json` | | Dataset (CSV) | `https://api.apify.com/v2/datasets/8bHR9g6W6rweGrGyI/items?clean=1&format=csv` | | Run summary (KVS) | `https://api.apify.com/v2/key-value-stores/0v7BO94xtGBhTUcFh/records/SUMMARY` | | Run details | `https://api.apify.com/v2/actor-runs/mchAnHhhEJh7N1MPk` | **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?
