Introduction

One token pair. Several pools. One reserve-aware price boundary.

Two Uniswap pools can hold the same tokens and quote very different prices. KNOT lets a group of new pools opt into one rule: no member may give a taker a better quote than both its own curve and a second curve computed from the members’ combined reserves.

Knot connects participating pools through one shared reserve ledger. Every swap is quoted twice and the trader receives the less favourable of the two. The clipped difference stays with the local pool’s LPs.

Exact input

output = min(local output, aggregate output)

This is arithmetic, not a prediction. There is no oracle or attacker classifier. The aggregate curve is an internal policy boundary; it is not an external fair price.

Before KNOT

See why independent pools for one pair can expose incompatible quotes.

Architecture

See which contract owns custody, accounting, and quote logic.

Trade against it

Claim test currency and execute a bounded swap from the browser.

What it is for

Enforces

A deterministic upper bound on what a member pays out, or lower bound on what it charges.

Does not claim

Fair-price discovery, toxicity detection, universal MEV protection, or realised LP profit.

Measured results

Metric	Value
Constructed cross-pool round trip	+13.5843 without the rule; -0.0298 with it
Quote reduction in the documented 4× fixture	6,674 bps of the isolated quote
Effect on a balanced pool	0 bps, the bound is inert
Advantage from splitting a trade 8 ways	none
Coalition-controlled member in the documented fixture	weakens the bound by 4,722 bps

Unaudited hackathon software. These constructed figures measure contract mechanics against the canonical v4 PoolManager; they do not measure realised LP P&L or production routing.
