DeFi Liquidation Tracker

Real-time on-chain liquidation events across Aave V3, Compound V3, and Spark Protocol. Track liquidator addresses, collateral seized, debt repaid, and USD value of every liquidation. Telegram alerts for whale-sized liquidations. No API key required.

What It Does

Liquidations are the single most actionable on-chain signal — they mark forced position closures during volatility spikes, expose stressed leverage, and reveal who the active MEV liquidators are. This Actor:

• Decodes Aave V3 LiquidationCall events from the mainnet Pool contract
• Decodes Compound V3 (Comet) AbsorbCollateral events across USDC/WETH/USDT markets
• Decodes Spark Protocol (Aave V3 fork) liquidations
• Resolves token symbols + USD prices via Coingecko
• Returns the liquidator address (= MEV bot), borrower, collateral seized, debt repaid, USD valuation, Etherscan link
• Sends Telegram alerts for liquidations above a configurable USD threshold

Why This Matters

• Whale liquidation = market-moving event. A $1M+ liquidation on Aave often precedes a sharp wick down as keeper bots dump seized collateral. This Actor surfaces those in real time.
• MEV bot leaderboard. The same handful of addresses absorb most liquidations. Watching their P&L is a direct signal of how lucrative liquidations are right now (= leverage stress).
• Health-factor scanner cross-reference. Pair this with liquidationCall history to backtest your own position safety margins.
