Pool creation in Likwid v2.2 starts from LikwidVault. A pool is initialized once for an ordered currency pair, and every later liquidity, lending, and margin action settles against that same pool state.

The pool core is intentionally minimal: it stores pricing, fee, reserve, and insurance-fund state, while user-facing interactions are exposed through the position-manager contracts.

The essential pool parameters are:

• Asset Pairing: currency0 and currency1, sorted by address in the vault.
• Swap Fee (fee): the base LP fee used by the swap engine.
• Margin Fee (marginFee): the fee collected on margin expansion.

Once initialized, the same pool can be used by:

• LikwidPairPosition for paired LP NFTs
• LikwidLendPosition for single-sided lending NFTs
• LikwidMarginPosition for leveraged margin NFTs

Additional capital can also be donated to the pool's insurance fund to strengthen stress-event handling.
