<summary>How does the off-chain engine work?</summary>

AMMs like Uniswap compute prices on-chain based on the number of tokens inside their smart contract.&#x20;

With Native’s tech, price computation can happen off-chain, while execution, settlement, and custody happens on-chain.&#x20;

The way the off-chain pricing works is similar to how 1inch and 0x use market makers to improve the depth of their books. Users get the best price, whether it comes from a market maker's off-chain price feed, or an AMM using on-chain pricing.

<summary>I already launched a pool with Native. Is it too late to change my pricing model or adjust the fees?</summary>

No! Whoever holds the private keys to the treasury wallet can change the pricing model or fee % at any point. Just change it in the admin panel and confirm with an on-chain signature. No migration of liquidity required.
