Stablecoin Depeg Monitor

Real-time peg deviation tracking for 380+ stablecoins (USDT, USDC, USDe, DAI, sUSDe, FRAX, PYUSD, FDUSD, RLUSD, USDS, and more). Get pinged when any stable wobbles. DefiLlama-powered. No API key required.

What It Does

Pulls live aggregated price and circulating supply for every tracked stablecoin and computes basis-point deviation from peg. Each row includes a severity label so you can wire alerts at any threshold:

Severity	Range	Meaning
NORMAL	< 10 bps	Within market microstructure noise
WATCH	10–50 bps	Slightly off — monitor closely
DEPEG	50–200 bps	Clear deviation — derisking signal
CRITICAL	> 200 bps	Active depeg event

---

Why This Matters

Stablecoins are the plumbing of crypto — every DeFi pool, every CEX pair, every yield strategy assumes they hold peg. When they don't, cascades happen fast:

• UST depeg (May 2022) wiped out $40B in 72 hours
• USDC depeg (Mar 2023, SVB) dropped to $0.87 in hours, took $3B+ of DeFi TVL with it
• USDe small wobbles in 2024-25 routinely preceded mNAV widening and Ethena negative basis

Catching deviation at 25 bps (0.25%) gives you minutes-to-hours to exit before the market notices. This Actor automates that watch.
