no, it ain't possible, grin has to be escrowed idiot
are a big fool.Stop your BS
I have done many non-btc escrow transactions..
Most escrows here only escrow btc for any trade ..even for non crypto trades
Go and check currency exchange or physical products market place ,to see escrows are used to exchange alter currencies ,gift cards and services
if I want to buy a miner or a physical item in market place ..will the seller escrows the item with escrow ?
Grin transactions can be checked with explorer
The buyer needs to send his grin address to escrow and escrow will forward it to seller and escrow can see the transaction on the blockchain through explorer
There is no rocket science in this
You are not a serious buyer..but searching for a prey to scam !
