# Market Maker System

The Market Maker (MM) is a key player in the Most Bridge design. They facilitate the quick transfer of assets between chains by providing liquidity and handling the cross-chain transactions.

## Role of the Market Maker

1. **Intent Fulfillment**: When you initiate a bridge transaction, the MM sees this intent and fulfills it on the destination chain.
2. **Liquidity Provision**: MMs use their own funds to send assets to you on the destination chain, allowing for near-instant transfers.
3. **Proof Submission**: After fulfilling an intent, the MM submits the proof using HDP to the source chain.
4. **Fee Collection**: In return for their service, MMs collect the fee you pay when initiating a bridge transaction.

## Benefits of the Market Maker System

* **Speed**: Allows for quick transfers without waiting for long confirmation times.
* **Efficiency**: MMs can batch transactions and optimize for gas fees, reducing costs.
