Stable Seer

Stable Seer is WalletWall’s dedicated surface for monitoring stablecoin peg risk, liquidity depth, issuer concentration, and cross-chain flow movement. It provides a focused lens on the stability and utility of the fiat-equivalent ecosystem. Stable Seer was previously named Market Radar. All identifiers, routes, and API endpoints were renamed as part of Epic #163.

Product boundary

Product	Focus	Primary metric
Holder Wall	Holder analytics	Ownership concentration, retention, distribution
Stable Seer	Stablecoin intelligence	Peg deviation, liquidity depth, issuer/flow risk
Whale Watcher	Activity intelligence	Large wallet movements, inflow/outflow alerts

Stable Seer does not provide holder analytics. The holderAnalyticsSupported: false flag is present on every API response as a hard invariant.

Covered stablecoins

Stable Seer prioritizes depth and stability analysis for:

Fiat-backed: USDC, USDT, PYUSD, FDUSD
Crypto-backed / over-collateralized: DAI, LUSD, crvUSD
Algorithmic / hybrid: FRAX, USDE

Data views

Peg stability and deviation

Real-time peg check: price variance from $1.00 across major DEX and CEX pairs
Historical volatility: frequency and depth of de-pegging events over 24h, 7d, and 30d windows

Liquidity and concentration

DEX liquidity depth: aggregated ±% depth for stable-to-stable and stable-to-volatile pairs
Issuer risk: concentration of supply within specific minting/redemption entities
Chain distribution: percentage of total supply deployed across Ethereum, Base, Optimism, Arbitrum, and other EVM-compatible chains

Supply and volume trends

Market cap momentum: 24h/7d change in circulating supply
Velocity: ratio of volume to market cap — identifies “parked” vs. “active” stablecoin capital

Protocol and flow movement

Inflow/outflow by protocol: stablecoin migration into and out of major DeFi protocols (Aave, Maker, Curve)
Whale movements: source-backed tracking of large stablecoin transfers between CEXs and unlabeled wallets

Supply & Flows panel (live)

The Stablecoin Supply & Flows panel ships today, backed by the free, keyless DeFiLlama stablecoins API (the /api/stablecoin-supply route, 6-hour durable cache with telemetry and graceful fallback):

Top USD-pegged stablecoins ranked by circulating supply
Per-coin 7-day and 30-day mint/redeem flow (net supply change)
Live peg deviation from $1.00
Backing mechanism label (fiat-backed, crypto-backed, algorithmic)

Homepage Market Context Rail

The WalletWall homepage carries a stablecoin market context rail fed by the same DeFiLlama source. Its chips include “The Largest” (dominance) and “The Biggest” — the stablecoin with the largest 7-day circulating-supply change, computed from circulatingPrevWeek and filtered to assets above $5M so a tiny coin’s noisy percentage swing cannot win the slot.

UI concepts

Concept	Description
Rein Check	High-confidence peg verification badge — signals when a stablecoin is trading within strict tolerance (e.g., $0.999–$ 1.001)
Stable Shopper	Interface for identifying the deepest liquidity pools for large-size stablecoin swaps
Herd Movement	Visualization of aggregate stablecoin flows between chains or into yield-bearing protocols
Pasture Map	Treemap of market cap distribution across issuers and chains
Barn Risk	Risk score based on collateralization transparency, liquidity depth, and historical peg stability

Risk Console

The Risk Console is a summary panel that aggregates peg deviation status, liquidity depth, issuer concentration risk, and the Barn Risk score for a selected stablecoin into a single view.

Risk scores are historical or point-in-time observations derived from scheduled Dune queries and market provider data. They are not investment advice and do not constitute a prediction of future peg stability.

Sparklines

Price sparklines display peg deviation history over selectable windows (24h, 7d, 30d). They are rendered from CoinGecko and DEX Screener market data, not from Dune scheduled queries.

Pool map

The pool map visualizes liquidity pool distribution for a selected stablecoin across DEX venues and chains. Pool data is sourced from DEX Screener.

Filters

Filters allow narrowing by chain, DEX venue, and stablecoin type (fiat-backed, crypto-backed, algorithmic). Filters operate client-side against the current result set.

Data sources

Source	Used for	Latency
CoinGecko	Price, volume, market cap	Low
DEX Screener	Liquidity depth, pool data	Low
Dune Analytics	On-chain supply distribution, historical flow movement	Scheduled/cached

All Dune Analytics data reflects the state of the last successful query execution and is not live. The UI labels Dune-sourced data as Scheduled/Cached.

Data flow

DEX Screener and CoinGecko supply live price and liquidity data; Dune supplies scheduled/cached on-chain supply-distribution context. Stable Seer reports supply change over a window, not a mint/redeem transaction flow — it observes public market and on-chain data and never initiates or tracks issuer mint/redeem activity directly.

API response shape

Stable Seer API endpoints return a normalized structure:

{
  "asset": "USDC",
  "data": {
    "price": 1.0002,
    "peg_deviation_bps": 2,
    "market_cap_usd": 32000000000,
    "liquidity_depth_2pct_usd": 450000000,
    "volume_24h_usd": 1200000000,
    "supply_distribution": {
      "ethereum": 0.85,
      "base": 0.10,
      "arbitrum": 0.05
    }
  },
  "metadata": {

      { "name": "Dune Analytics", "type": "on-chain-scheduled", "last_updated": "<scheduled_timestamp>" }
    ],
    "confidence_score": 0.98
  }
}

Stablecoin Vault handoff

Stable Seer’s stablecoin exposure signals — peg health, issuer concentration, liquidity depth, and cross-chain flows — are inputs to the Stablecoin Vault readiness assessment (vault.walletwall.org / /stablecoin-vault). When a user has a wallet address in context, Stable Seer data contributes to the readiness engine that determines whether the wallet is a candidate for the testnet vault rehearsal. The Stable Seer product boundary is intelligence-only: it does not initiate vault enrollment, does not suggest financial actions, and does not provide advice. The Stablecoin Vault is the action-layer destination.

An internal, unwired data foundation for Aave v3 Ethereum stablecoin-reserve yield evidence (supply APY, reward APY, total APY, and market-level TVL, sourced from DeFiLlama’s yields API) exists as a shadow feature layer intended to feed future Stable Seer market context. It is not surfaced in any UI, score, or recommendation today — no yield ranking, no “best rate,” no projected return.

Guardrails

All Dune data is labeled as scheduled and cached — never live.
Solana holder analytics are not supported. Aggregate market-level data (price/volume) for Solana-based stablecoins may be available via market providers only.
No deanonymization: attribution is limited to public and source-backed labels.
Data is for informational purposes only. Not investment advice.

Quantum Intelligence

Quantum exposure and dormancy facts are stablecoin-scoped (curated stablecoins_multichain.* Dune tables) — the same stablecoin domain Stable Seer monitors for peg and liquidity risk.

Stablecoin Vault

Stable Seer’s peg, issuer-concentration, and liquidity signals are inputs to the Stablecoin Vault readiness assessment — the action-layer destination.
