Reasoning

All addresses received exact 0.2 xDAI from the same address 0xe47f31e4d284548cfcc91541d8b107a94a8dec60 during the time from 11/9/2021 2:03:00 PM to 11/9/2021 2:05:17 PM on the Gnosis chain.

Each destination address then employed hop to send USDT from Gnosis to Polygon, and back to Gnosis.

A few examples are here: https://explorer.hop.exchange/?account=0xc593ea41ec2ab22b7861b7eaf74c6e6412cb46c0 https://explorer.hop.exchange/?account=0xf7bfffce353630924121a28b1f0d5b3d26185521 https://explorer.hop.exchange/?account=0x05a7b63d048364ee3eb98c87a2bb00645e4e66a4
