Implemented and tested contracts

ABI documentation and an independently reviewed launch.json.

HourlyFeeHook

A simple, creative Uniswap v4 hook: a dynamic-fee hook that charges a different LP fee by UTC hour: a 24-entry fee schedule fixed at construction (in hundredths of a bip, each at most 1%), applied in beforeSwap from block.timestamp.

PriceMoveBreakerHook

A simple, creative Uniswap v4 hook: a simple circuit breaker: afterSwap records the pool tick per block, and if the tick has moved more than 1000 ticks within the last 100 blocks the hook refuses swaps in that pool for the next 50 blocks, then resumes; a bounded ring of observations, no admin.

Sealed Bid Auction

Linear Vesting

Token Vest (VEST) and contract LinearVesting, where anyone creates a schedule for a beneficiary by depositing VEST with a start, a cliff and a duration; the beneficiary claims the vested portion at any time, with exact linear arithmetic and no rounding leak.
