Add coverage for layerswap - Shido exploiter

[Ivan1905]

Hi there,

I have just reviewed the Shido Exploit.

• Attacker was funded by layerswap on arbitrum. Tx here
• Then bridged to Mainnet. tx here

I was wondering if we could add coverage for layerswap

Adding to backburner while we decide on a better way of funding detection
