What Pegana does

Pegana watches 63 active pegged assets on Solana mainnet in real time (plus inactive entries kept for history). For every asset, we compare market price to intrinsic value, smooth the spread with an EWMA, and publish a peg state through a 5-state FSM: PEGGED · DRIFT · DEPEG · CRITICAL · BLACK_SWAN. (UNKNOWN is a separate non-alerting status — cold-start or a detectably broken anchor — not a severity band.) When the state changes, we emit an alert. That’s the whole product.
Everything else is plumbing.

Coverage

63 active assets across 7 classes — mainnet only, no devnet feeds. Source of truth: assets.toml; the canonical live list, with each asset’s current peg state, is always GET /v1/assets. Of the 63, 50 are beta (monitoring_only): their alerts are live and labeled beta, but the calibration is provisional, so those reads should be treated as experimental until they graduate. The asset set grows over time — treat this table as a snapshot and GET /v1/assets as the source of truth for what is live right now. Inactive entries (in assets.toml with active = false, not polled, so not in the 63): BRZ (BRL FX-pegged) and pbUSDC — deactivated 2026-06-01 (only thin dust DEX pairs left, prices unreliable). dSOL was removed after the Drift exploit (2026-04-01) and survives only as a historical comment.

What we promise

  • Methodology is public. Every threshold, every source, every smoothing parameter lives in /methodology. No black box.
  • Open methodology + verifier (MIT). The math behind every threshold and the pegana-replay CLI that reproduces any receipt are public at github.com/lrafasouza/pegana-replay — re-derive any verdict yourself. The operational services run from a separate repo.
  • No API key for reads. REST, WebSocket and Embed are public. Only the MCP paid tools require x402 settlement.
  • One source per asset class. We do not “blend” prices. Sanctum exchange rates — or a direct on-chain stake-pool read for LSTs outside the Sanctum registry — for LST intrinsic; Pyth for FX and for yield-bearing redemption rates; on-chain vault/CDP decode for Hylo, Solayer, and Perena USD*; Jupiter for routed market price.
