Canonical Market Definition

Each PURITY launch defines exactly one canonical market, created at deployment: a constant-product AMM pair between the token and the base asset. The Treasury's constructor creates this pair itself, and the pair address is immutable from that moment — there is no mechanism to re-point a launch at a different venue.

In the current implementation the base asset is ETH (held internally as WETH), with Base as the reference chain. The design generalises: the standard is chain-agnostic, and a deployment selects its chain and base asset at deployment time.

The canonical pool is the sole source of every market signal the Treasury consumes:

• price — computed directly from the pool's reserves,
• reserves — read directly from the pair,
• buying-pressure signals — measured as changes in the pool's base-asset reserve over time.

The constraints follow from that exclusivity. Treasury logic ignores all other pools and venues. No external price oracles are used, no time-weighted averages, no cross-pool aggregation, no off-chain data feeds. Every swap the Treasury executes references canonical pool reserves only.

This deliberately trades sophistication for robustness. Anchoring all behaviour to a single explicit market eliminates ambiguity about which price the system is responding to, removes the oracle-manipulation surface entirely, and keeps every input to the engine auditable from one contract. Arbitrage will connect external venues in practice — but the Treasury's behaviour is anchored to one source of truth that anyone can read.

The Treasury owns 100% of the initial LP in the canonical pool. Third parties may add liquidity afterward, which dilutes the Treasury's proportional LP ownership over time; the market-making logic operates on its own position and does not depend on holding 100% of LP at all times.
