@luxfi/dex
Lux DEX SDK — V4 CLOB precompiles, order book client, and routing.
TypeScript SDK for the Lux DEX stack. The V4 surface is a central limit order
book (CLOB), not an AMM: swap is a marketable order, modifyLiquidity
places/cancels a resting limit order, and price comes from the book rather than
a bonding curve. Settlement happens on the D-Chain over ZAP.

The LXPool facade exposes the standard V4 ABI so existing viem/wagmi tooling
works unchanged; the PoolKey/SwapParams shapes mirror Uniswap V4 for ABI
compatibility, but the curve scalars (sqrtPrice/tick) are facade values and
fills come from the resting book. The facade is inert until the venue sets a
dex-zap-endpoint, degrading gracefully when unset.
