SOL-pegged LSTs
Source: Sanctum’ssol_value per LST mint.
sol_value — for jitoSOL today,
1 jitoSOL ≈ 1.18 SOL because the underlying stake pool has accrued staking + MEV
rewards since the asset was minted.
Tracked LSTs: jitoSOL, mSOL, bSOL, INF, bbSOL, JupSOL, plus the Hylo
LSTs hyloSOL, hyloSOL+.
Fiat stables
Source: the issuer’s contract =$1, no exception.
USDC, USDT, PYUSD, USDS, USDe all peg to 0.998, that’s
a -2 bps spread; if it trades at $0.87 (the 2023 SVB weekend), that’s -1300 bps.
We do not introduce a hardcoded 1.0 in the schema — the intrinsic comes from the
configured peg target (USD, EUR, etc.) and is read from Pyth like any other FX.
Yield-bearing NAV stables
Source: Pyth Redemption Rate (USDY, syrupUSDC, sUSDe, ONyc), or the mint’s on-chain InterestBearing extension (sUSD).1 USDY ≈ $1.08 today because the underlying T-bill
strategy has earned ~8% since launch. Treating these as $1-pegged would systematically
under-value the position.
For issuers that haven’t published a Pyth feed yet (Perena USD*, Piggybank pbUSDC), we
scrape the dashboard NAV and tag the asset verified=false in assets.toml until a
real feed lands.
CDP-style stables
Source: on-chain decode of the protocol’s collateral state. For Hylo’s hyUSD:FX-pegged assets
Source: Pyth for the underlying FX rate, multiplied by the issuer’s redemption claim. A EUR-pegged stable should redeem atpyth.EUR/USD per token. Drift from that
is the spread.
We currently track no EUR-pegged Solana asset, but the engine path is wired for it.
Why one source per class
Two reasons:- Determinism. When you ship a single alert that says “USDC entered DEPEG at 14:32:11,” subscribers need to be able to reproduce that decision from raw inputs. A blended price (Pyth + DEX1 + DEX2, weighted somehow) is reproducible only with the weighting algorithm published — and even then is harder to argue from.
-
Failure mode honesty. If Sanctum’s
sol_valueis wrong, every Pegana LST signal is wrong, and we want to know loudly. If we blended Sanctum with a DEX-side LST redemption proxy, a Sanctum bug would be masked by the proxy. We prefer the loud failure.
UNKNOWN rather than emitting a confident-but-wrong number.
