Building robust DeFi markets is about deliberate design.
Echoing insights summarized by one of the risk curators on recurring failure modes, Pike is engineered from day one to avoid them.🧵
2/ Failure Mode 1: Mis-set interest-rate models
In utilization-based models, the “kink” is a monetary policy lever.
• Too low: withdrawal liquidity evaporates, lenders feel trapped.
• Too high: suppliers under-earn, spreads balloon, capital sits idle.
Either way — fragility follows.
3/ Pike fixes this with a 3-slope Interest Rate Model (IRM) — an evolution beyond the classic 2-slope curve.
• Low utilization: lower rates attract early borrowers and reward sticky deposits
• Normal utilization: smooth transition avoids sudden jumps
• High utilization: steep slope restores balance when borrowing surges
4/ Each market’s parameters are fine-tuned by the Governor (Curator), who can manage:
• First & second kink points
• Kink multipliers for each segment
• Base rate settings per asset
This flexibility lets Pike tailor interest curves for different market behaviors.
5/ This 3-slope IRM enhances liquidity predictability and rate stability during stress.
No abrupt cliffs. No liquidity traps.
And because Pike’s parameters are dynamically adjusted with real-time on-chain data and volatility metrics, they stay aligned with actual market conditions.
6/ Failure Mode 2: Fragile oracles for illiquid or self-reported assets
Relying on a single oracle is asking for chaos.
If one feed lags, breaks, or is manipulated, the entire collateral base becomes unstable.
(Remind: Pike’s modular architecture isolates markets, so bad debt in one market never spreads to others.)
7/ Pike’s answer: the Dual-Oracle System.
It cross-verifies price data from multiple oracles and automatically prioritizes the safer feed if one diverges.
Governors can select preferred oracle sources per market, ensuring flexibility and redundancy.
8/ Pike’s Engine is built for resilience:
• Dual-Oracle Architecture (e.g., Chainlink + Pyth)
• A configurable Fallback Mechanism
• Price Validation via automated bounds checking between main and fallback feeds
• Transaction is reverted if ****neither oracle provides a valid price
This multi-layered setup ensures accurate and tamper-resistant pricing, even in volatile markets.
