openhands cb6d6e2292 fix: LM recenter() return semantics undocumented (#570)
Add NatSpec to recenter() documenting that the function always reverts
on failure (never silently returns false), listing all four revert
conditions, and clarifying that both true/false return values represent
a successfully-executed recenter with the value indicating price
direction (up vs down relative to previous anchor centre).

Also fix StrategyExecutor.maybeRecenter() to capture the isUp return
value from lm.recenter() and include it in the log output, making
price direction visible in backtesting replays.

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

  1. Harberger — A staking market balanced by the Harberger tax. Complete.
  2. KRAIKEN — Token issuance governed by an automated liquidity manager. Current stage.
  3. 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.

Quick Start

# Prerequisites: Docker Engine (Linux) or Colima (Mac)
# See docs/docker.md for installation

nohup ./scripts/dev.sh start &    # Start full stack (~3-6 min first time)
tail -f nohup.out                  # Watch progress
./scripts/dev.sh health            # Verify all services healthy
