An experimental ERC20 token implementing adaptive tokenomics through an auto-adjusting transfer tax. The contract monitors recent transfer volume in a configurable time window and dynamically increases or decreases fees based on market activity. A clean, dependency-free demonstration of self-regulating, volume-responsive economic design.

Goldsky subgraph for Spry, the dynamic-fee Uniswap V4 hook. Indexes pools, per-swap tier-aware fees, and the hook's fee-curve telemetry for LP analytics.

Web interface for Spry, the dynamic-fee Uniswap V4 hook. Swap, provide liquidity, and create pools across the five fee tiers; a Spry-native Uniswap-interface fork on Unichain Sepolia & Base Sepolia.

A Uniswap v4 hook that sets the LP fee from the pool's realized volatility to reduce loss-versus-rebalancing (LVR). Solidity/Foundry, with an LVR simulation harness measuring the effect on real mainnet pools.

Uniswap V4 hook that dynamically adjusts swap fees based on real-time pool volatility using an EWMA model. Calm market → 0.05%. Volatile market → 1.00%. No oracle, no off-chain data — pure on-chain math in a single beforeSwap callback. Deployed on Sepolia.
