Wrap the fallback pool.observe() call in a try/catch so that pools with insufficient observation history for both the primary (30s) and fallback (6000s) intervals return false (price unstable) instead of reverting with an opaque Uniswap V3 error. This prevents recenter() from failing for unpermissioned callers on newly created pools. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> |

KRAIKEN
The fairest ponzi in the world.
KRAIKEN is a DeFi protocol that couples Harberger-tax staking with a dominant Uniswap V3 liquidity manager. The result: asymmetric slippage, sentiment-driven pricing, and VWAP-based price memory that protects the protocol from exploitation.
Deployed on Base.
The Three Stages
- Harberger — A staking market balanced by the Harberger tax. Complete.
- KRAIKEN — Token issuance governed by an automated liquidity manager. Current stage.
- SoverAIgns — The liquidity manager augmented by AI for outlandish performance. Future.
How It Works
Three-Position Liquidity Strategy
The LiquidityManager maintains three Uniswap V3 positions simultaneously:
- Anchor — Shallow liquidity near the current price. Fast price discovery, high slippage for attackers.
- Discovery — Medium liquidity bordering the anchor. The fee capture zone.
- Floor — Deep liquidity at VWAP-adjusted distance. Price memory that protects against whale dumps.
Any round-trip trade (buy → recenter → sell) pays disproportionate slippage costs twice, making manipulation unprofitable.
Harberger Tax Sentiment Oracle
Stakers self-assess tax rates on their positions. Higher tax = higher confidence. Positions can be snatched by anyone willing to pay more. This creates a continuous prediction market for token sentiment.
OptimizerV3
Reads staking data (% staked, average tax rate) and outputs a binary bear/bull configuration:
- Bear (~94% of state space): AS=30%, AW=100, CI=0, DD=0.3e18 — protective
- Bull (>91% staked, low tax): AS=100%, AW=20, CI=0, DD=1e18 — aggressive fee capture
The binary step avoids the AW 40-80 kill zone where intermediate parameters are exploitable.
VWAP Floor Defense
The floor position uses volume-weighted average price with directional recording (buys only). During sell pressure, the VWAP-to-price distance grows, making the floor resist walkdown. This gives the protocol "eternal memory" against dormant whale attacks.
