# CEX Reserve Tracker — Exchange Wallet Balances (BTC/ETH) (`gochujang/cex-reserve-tracker`) Actor Live BTC / ETH / USDT / USDC reserves at major CEXs (Binance, Coinbase, Kraken, OKX, Bybit). Track exchange outflows = bullish (custody), inflows = bearish (sell pressure).

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 ## CEX Exchange Reserve Tracker > Query on-chain wallet balances for **Binance, Coinbase, Kraken, Bitfinex, OKX, and Bybit cold/hot wallets** across **ETH, USDT, USDC, WBTC, and DAI**. Reserve trends are the single most-watched macro signal in crypto. No API key required. --- ### What It Does Exchange reserves are aggregate balances of well-known CEX cold wallets. Watching them is how funds, market makers, and serious analysts read macro flow: - **Falling reserves** + **growing stablecoin reserves** = capital ready to deploy = bullish - **Rising ETH/BTC reserves** = inventory build for distribution = bearish - **Stablecoin reserve growth** = sidelined buyers entering = bullish This Actor returns the **current balance per wallet × asset** with USD valuation, plus per-exchange and per-asset totals. Schedule it to build your own time-series. --- ### Why This Matters CEX reserve data has historically called major tops and bottoms (notably FTX-induced reserve drops, post-Luna inflows, 2024 ETF launch deposits). Live reserve snapshots are what institutional desks pay $5K+/month for from CryptoQuant. This Actor delivers a useful slice for fractions of a cent. --- ### Input | Field | Type | Default | Description | |-------|------|---------|-------------| | `exchanges` | array | all | Subset of `Binance, Coinbase, Kraken, Bitfinex, OKX, Bybit` | | `assets` | array | all | Subset of `ETH, USDT, USDC, WBTC, DAI` | | `minBalanceUsd` | integer | `1000000` | Skip wallets with < $X for an asset | | `sortBy` | string | `balance_usd_desc` | `balance_usd_desc`, `exchange_asset`, `asset_only` | | `limit` | integer | `200` | Max rows | #### Example: Binance + Coinbase USDT only ```json {"exchanges": ["Binance", "Coinbase"], "assets": ["USDT"]} ```` #### Example: All-asset snapshot for daily ETL ```json {"sortBy": "exchange_asset", "minBalanceUsd": 0, "limit": 500} ``` *** ### Output ```json { "exchange": "Binance", "asset": "USDT", "wallet_label": "Binance 8 (Cold)", "wallet_address": "0xf977814e90da44bfa03b6295a0616a897441acec", "balance_native": 19967378227.0, "balance_usd": 19967378227.00, "price_used_usd": 1.0 } ``` Plus a **SUMMARY** key-value record with totals by exchange and asset. *** ### Pricing - **$0.001 per (wallet × asset) row returned** Examples: - Full snapshot (~6 exchanges × ~3 wallets × 5 assets ≈ 90 rows): **~$0.09** - Single exchange focus (~5 rows): **$0.005** *** ### Use Cases **Daily reserve report** — Schedule daily, compare against prior day's stored snapshot, alert on > 5% delta. **Stablecoin inflow signal** — Filter `asset: "USDT"` + `sortBy: "exchange_asset"`, watch totals daily. Sustained Tether inflow = sidelined buying power. **Coinbase ETH outflow tracker** — Coinbase's ETH balance trends correlate with custody-into-staking flows (which precede price moves). *** ### Limitations - Only Ethereum L1 wallets are scanned. Doesn't cover BSC, Solana, Tron, or BTC native chain. - The wallet list is **curated public knowledge**, not exhaustive. Some exchange reserves live in wallets not in the public domain. - Snapshot only — no historical time-series. Run on a schedule and compare runs to derive trends. *** ### Data Sources - **Etherscan V2 API** (`module=account&action=balance / tokenbalance`) — shared API key bundled - **Coingecko** for USD pricing *** ### Related Actors - **[Stablecoin Depeg Monitor](https://apify.com/gochujang/stablecoin-depeg-monitor)** — Pairs nicely with stablecoin reserve trend. - **[Crypto ETF Flow Tracker](https://apify.com/gochujang/crypto-etf-flow-tracker)** — ETF inflows + CEX reserve drops = high-confidence rally signal. - **[Smart Money Wallet Tracker](https://apify.com/gochujang/smart-money-tracker)** — On-chain whale activity complement. *** *** ### 🎬 Live Sample Run A real run of this actor with default-ish inputs, executed on 2026-06-10: | Field | Value | |---|---| | Items in dataset | 6 | | Dataset (JSON) | `https://api.apify.com/v2/datasets/OWU4mBUMugpxfTDCI/items?clean=1&format=json` | | Dataset (CSV) | `https://api.apify.com/v2/datasets/OWU4mBUMugpxfTDCI/items?clean=1&format=csv` | | Run summary (KVS) | `https://api.apify.com/v2/key-value-stores/JDcBEth0cwsnvXs2M/records/SUMMARY` | | Run details | `https://api.apify.com/v2/actor-runs/axMZBMPfmQ35J6Tp3` | **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?
