# AMM Liquidity Pools

{% hint style="info" %}
**Disclaimer:** [here](https://docs.relicsprotocol.com/relics/introduction/disclaimer)
{% endhint %}

Once a relic mints out, depending on its mint terms, the accrued $MBTC will be put into a liquidity pool together with the configured amount of the minted relic. Following you will have a pair like e.g. MBTC/WE•LOVE•RELICS. The AMM pool operates on the same price curve as [Uniswap V2](https://docs.uniswap.org/contracts/v2/concepts/protocol-overview/how-uniswap-works).

The fee of the pool can be controlled by whoever owns the relic inscription. After setting them initially, they can only be decreased and never again increased.

## Swaps

Swap protocol messages typically come with the following options: 

| Parameter       | Description                                                                         |
| --------------- | ----------------------------------------------------------------------------------- |
| Input relic     | Specifies the input relic, defaults to MBTC                                         |
| Output relic    | Specifies the output relic, defaults to MBTC                                        |
| Input amount    | Min/max amount of input tokens                                                      |
| Output amount   | Min/max amount of output tokens                                                     |
| Is exact input? | If false, this is an exact-output swap. If true, this is an exact-input input swap. |

### MEV?

One measure to reduce MEV ([Miner Extractable Value](https://bitcoinmagazine.com/technical/miner-extractable-value-mev-and-programmable-money-the-good-the-bad-and-the-ugly)) is to prevent tokens bought in one block from being sold again in the same block. This means that if a sniper wants to sandwich a purchase of 10 WE•LOVE•RELICS for 1 MBTC with a 10% slippage, they must either assume multi-block risk or hold a substantial amount of WE•LOVE•RELICS. In that case, they would function more as a market maker than as an MEV extractor.
