# Definition

Within the framework of Soiler, various significant terms and concepts are employed to elucidate the transactional procedure and the functions of Makers. Below are the fundamental definitions:

**Limit:** The limit refers to the maximum amount allowed for a transaction. It represents the maximum value that can be transferred from the source network to the destination network within a single transaction. It ensures that transactions adhere to certain size restrictions.

**Minimum Transaction Value:** The minimum transaction value is the minimum amount of Ether (Eth) required for a transaction to be valid. In Soiler, the minimum transaction value is set at 0.005 Eth.

**Withholding Fee:** The withholding fee is a one-time charge that covers the cost of gas for transfers from the source network to the destination network. It is deducted from the transaction amount to cover the gas fees associated with the transfer.

**Trading Fee:** Makers have the option to choose a percentage of the trading value they wish to receive from each transaction. This fee is a percentage of the transaction amount and serves as compensation for the services provided by the Maker.

**Liquidity:** Makers are recommended to maintain a certain amount of liquidity in their externally owned address (EOA). This liquidity, typically between 110-180 Eth, ensures that Makers can respond to transaction demands and fulfill their role effectively.

* **Excess Margin:** Makers are required to deposit excess margin in the Maker Deposit Contract (MDC). This excess margin acts as collateral to cover potential losses or compensation for Senders in case of transaction failures or disputes. Makers have the flexibility to adjust the amount of excess margin by modifying the limit for each transaction pair.
* **Removal of Node:** When a Maker decides to remove their Maker Node from the network, they will receive the total amount of excess margin that was deposited in the MDC Contract.

These concepts and guidelines shape the functioning of the Maker role in Soiler, ensuring liquidity, security, and fair compensation within the protocol.
