DeFi Liquidation Tracker — Aave Compound Maker Live Events

DeFi Liquidation Tracker — On-Chain Lending Protocol Liquidations Monitor

Real-time DeFi liquidation tracker for Aave V3, Compound V3, and Spark Protocol. Monitor every on-chain liquidation event including collateral seized, debt repaid, liquidator address, and USD value. Get Telegram alerts for whale-sized lending protocol liquidations before the market reacts. No API key required — runs on Apify's cloud infrastructure.

Liquidations are the most actionable forced-selling signal in DeFi. A $1M+ Aave liquidation means a keeper bot is about to dump seized collateral on the open market — knowing this seconds after it hits the chain is the edge that separates informed traders from the crowd. This Actor surfaces that information as clean structured JSON, delivered via Apify's reliable execution environment with zero infrastructure setup.

What does DeFi Liquidation Tracker do?

The DeFi liquidation tracker decodes on-chain event logs from three major Ethereum lending protocols — Aave V3, Compound V3 (Comet), and Spark Protocol — and returns every liquidation event within your configured lookback window. For each event it provides: the borrower address, liquidator bot address, collateral asset seized (with symbol and USD value), debt asset repaid, total liquidation value in USD, and a direct Etherscan link. Apify's scheduling and persistent datasets mean you can run this hourly with automatic alert delivery and a permanent archive of every liquidation surfaced.

Liquidation data that institutional DeFi desks pay premium data providers for is now accessible as a pay-per-use API — no subscriptions, no data engineering, no rate-limit management.

Why use DeFi Liquidation Tracker?

• Whale liquidation early warning. Large liquidations ($500K+) on Aave or Compound are often followed by sharp price wicks as keeper bots dump seized collateral (rETH, wstETH, WBTC) on spot markets. Catch these seconds after on-chain confirmation.
• MEV liquidator intelligence. The same handful of addresses absorb most DeFi liquidations. Tracking the liquidator field across runs builds a real-time leaderboard of active MEV bots and measures how profitable liquidations currently are — a direct proxy for leverage stress in the system.
• Risk management for DeFi positions. Understanding when and why similar collateral types get liquidated helps you calibrate your own health factor buffers. Pair with historical data to backtest safety margins.
• Cascade post-mortems. After flash crashes or oracle manipulation events, reconstruct the full liquidation cascade by pulling every event in the impacted block range — essential for protocol risk analysis and insurance modeling.
• Protocol health monitoring. Sustained high liquidation volume signals elevated systemic leverage — a macro DeFi risk indicator used by protocol treasuries and risk committees.

FAQ

Q: Which Ethereum contracts are decoded? Aave V3 Pool at 0x87870Bca3F3fD6335C3F4ce8392D69350B4fA4E2, Compound V3 Comet markets (USDC, WETH, USDT), and Spark Pool at 0xC13e21B648A5Ee794902342038FF3aDAB66BE987. All mainnet addresses.

Q: How far back can I look? lookbackBlocks is configurable. One Ethereum day is approximately 7,200 blocks (~12 seconds/block). For a 7-day lookback use 50400. Very large lookback windows may increase run time to several minutes depending on event density.

Q: Does this cover L2 protocols (Aave on Arbitrum, Base, etc.)? Currently only Ethereum mainnet is supported. L2 protocol coverage is on the roadmap.

Disclaimer: Liquidation data is derived from public on-chain event logs. USD valuations use CoinGecko prices at run time and may differ from prices at the exact moment of liquidation. This is not financial advice.
