## Earn an arbitrage for fulfilling cross-chain limit orders via DLN, completely non-custodially

### Description

In DLN, when a maker creates a cross-chain limit order, takers on the destination chain are able to track and analyze all the incoming trades with the taker script and can automatically fulfill it if it’s profitable.

The taker that fulfills the order first then broadcasts a cross-chain message to the source chain through deBridge infrastructure to unlock the assets on the source chain, therefore earning an arbitrage spread. Routing is built in a way so takers don’t need to bear volatility risks as they provide and unlock the same asset e.g. USDC or ETH.

### Difficulty

Low to medium - depending if complex trading / rebalancing strategies are desired by the designated taker

### Is this a one-off opportunity or is it reoccurring?

This is a reoccurring MEV. As cross-chain limit orders continue to pass through DLN, there will be more opportunities to fulfill limit orders.

### Steps to capture MEV

1. Set up a wallet address on a compatible chain.
2. Add a balance sheet of tokens onto the wallet address that aligns with the taker’s trading strategy (usually ETH and USDC).
3. Run the taker script to automatically identify cross-chain limit orders: https://github.com/debridge-finance/dln-taker/
4. Start fulfilling cross-chain limit orders and rebalance liquidity if needed.
