Stablecoins Monitor — Supply, Peg & Chains

   

Every stablecoin's supply, growth and peg health — in one exportable table. 380+ stablecoins from DefiLlama: circulating supply, 1d/7d/30d growth, current price, peg deviation (the depeg signal), peg type & mechanism, dominant chain and chain count — as clean CSV/Excel rows.

No API key, no proxy — one request per run, built for a scheduled "stablecoin supply & depeg" feed.

Two things it's great at

1. Supply leaderboard — who's biggest and who's growing:

Stablecoin	Supply	Price	Mechanism	Top chain
Tether (USDT)	$187.19B	$0.9988	fiat-backed	Tron
USD Coin (USDC)	$75.96B	$0.9997	fiat-backed	Ethereum
Sky Dollar (USDS)	$8.75B	$0.9997	crypto-backed	Ethereum

2. Depeg hunt — surface coins off their $1 peg (minPegDeviation: 1, sortBy: pegDeviation): instantly finds broken/collapsing pegs (e.g. failed algorithmic stablecoins trading at cents on the dollar).

Quick start

{
  "minCirculating": 1000000,
  "sortBy": "circulating",
  "maxResults": 500
}

Presets to try:

• Biggest stablecoins — sortBy: circulating
• Depeg watch — minPegDeviation: 1, sortBy: pegDeviation
• Fastest-growing this week — sortBy: change7d, minCirculating: 1000000
• Algorithmic only — pegMechanism: algorithmic
• On one chain — chain: "Tron" (or Ethereum, Solana, BSC…)

No API key, no proxy, no setup.

Why this actor

• Supply + peg health in one feed — the two things stablecoin analysts watch, ranked and filterable.
• Depeg detection — peg-deviation filter surfaces coins drifting off $1 before headlines do.
• Free source, zero cost to run — DefiLlama's public stablecoins API; no key, no proxy, one request.
• Schedulable — re-run daily for a live stablecoin dataset into a sheet, dashboard or risk model.

Data sourced from DefiLlama's public stablecoins API. Peg deviation is computed for USD-pegged assets (target $1).
