Hello,
As a reminder, do not send the coins from CoinPayments. It’s best to send them from another Litecoin testnet wallet. I did send you coins from my testnet wallet to the deposit addresses you indicated. The chain.so explorer displays addresses in their non-P2SH format, this is why they appear different.
1. Did your coinpayments account receive the testnet coins I sent you?
2. Did the deposits appear in the plugin?
Let me know please if you can. Thank you.
