The relayer is a service that listens to the RFQ contract for new RFQs and optimistically relays requests to the destination chain. The relayer can then claim the funds on the origin chain after waiting a short time. The relayer is also responsible for continuously posting api quotes with it's available balances so clients know how much liquidity is available.

MD013 - Line length

Tags: line_length

Aliases: line-length Parameters: linelength, codeblocks, tables (number; default 80, boolean; default true)

This rule is triggered when there are lines that are longer than the configured line length (default: 80 characters). To fix this, split the line up into multiple lines.

This rule has an exception where there is no whitespace beyond the configured line length. This allows you to still include items such as long URLs without being forced to break them in the middle.

You also have the option to exclude this rule for code blocks and tables. To do this, set the code_blocks and/or tables parameters to false.

Code blocks are included in this rule by default since it is often a requirement for document readability, and tentatively compatible with code rules. Still, some languages do not lend themselves to short lines.

Parameters: style ("one", "ordered"; default "one")

This rule is triggered on ordered lists that do not either start with '1.' or do not have a prefix that increases in numerical order (depending on the configured style, which defaults to 'one').

Example valid list if the style is configured as 'one':

1. Do this.

1. Pre-Status: An on-chain transaction emits the event [`BridgeRequested`](https://vercel-rfq-docs-trajan0x-synapsecns.vercel.app/contracts/interfaces/IFastBridge.sol/interface.IFastBridge.html#bridgerequested). We store this event in the db with the status `Seen` & wait for the db processor to pick it up.

The relayer consists of two main loops that contain the entire business logic of the relayer. The first loop is the `chainParser` loop which listens for events from on-chain and processes them. The second loop continously pools the db for events in the db which are unfinalized by their status and checks if they can be moved through the queue. Below, we'll go through the full lifecycle of a transaction and the statuses that different paths.
