Pyron

Pyron is a lending protocol on Fogo, a high-performance layer one built on the Firedancer client with roughly 40-millisecond blocks. It turns idle assets into interest-bearing pools that borrowers draw against with overcollateralisation, positioning itself as the chain's asset productivity layer.

Each asset sits in its own pool, and rates follow a two-segment piecewise linear curve that stays low at low utilisation and rises sharply to protect depositors when liquidity tightens. Borrowing power depends on each asset's collateral weight, and when an account's health factor falls below the threshold a partial liquidation sells just enough collateral to restore safety rather than closing the whole position. Risk tiers split assets into collateral, borrow-only and isolated, with isolated assets requiring a dedicated position to stop contagion. Pricing uses a dual oracle with confidence bounds and staleness protection, and the risk engine recomputes weighted account value each block while third-party liquidators execute and collect fees.
