Shit, I've done this with TrustDice deposit. Arbitrum USDC sent to ETH USDC address.
Naturally, support rep says 'Dear customer, we're unable to help, it's your mistake'
If anyone has a clue what else I can try to persuade them 'to try', I'd really appreciate any tips. I'm a newb lol
I think the blockchain doesn't really matter as long as it's same deposit addy. Sometimes, a platform can provide two different deposit addy even when it's compatible each other like ETH and ARB.
Have you checked whether it's same addy between ETH and ARB? If you have checked it, then TD refuses to help you on this, they owe you.
This pretty much the same like my case. When i sent my stable token use ARB blockchain. I wrongly sending it using OP blockchain, but my stable was remain accessible, and successfully delivered to my exchange's account.
The only thing you can do is always pushing them. The have access you your funds.
