USDT0 transfer blocked on Plasma Mainnet despite showing 0.00 XPL network fee - Paymaster not recognized

[sugengprasetyocatur-arch]

Describe the bug
USDT0 transfers on Plasma Mainnet are being
blocked by Trust Wallet despite the app itself
showing Network fee = 0.00 XPL.

The error message says:
"You don't have enough Plasma Mainnet (XPL)
to cover network fees."

This is incorrect behavior. Plasma Mainnet has
a built-in Paymaster system that sponsors gas
fees for all basic USDT0 transfers. Users should
NOT need any XPL balance to send USDT0 on
Plasma Mainnet.
To Reproduce

1. Open Trust Wallet
2. Select USDT0 on Plasma Mainnet
3. Tap "Send"
4. Enter any valid Plasma Mainnet address
5. Enter any amount of USDT0
6. Tap "Next"
7. Confirm screen shows Network fee = 0.00 XPL
8. App still blocks transaction with error:
   "You don't have enough Plasma Mainnet (XPL)"
9. Transaction cannot proceed without XPL balance
   Expected behavior
   USDT0 transfer should complete successfully
   without requiring any XPL balance.

Plasma Mainnet's Paymaster system sponsors
gas fees for basic USDT0 transfers at the
protocol level. This means:

• Network fee = 0.00 XPL (as already correctly
  displayed by Trust Wallet UI)
• Transaction should proceed without XPL balance
• No gas token required for simple USDT0 sends

   Additional context

• Wallet name: CoinLabs (Trust Wallet)
• Token: USDT0
• Network: Plasma Mainnet
• Issue: Trust Wallet does not recognize
  Plasma's Paymaster/gasless transaction system
• Other wallets and Plasma's own interface
  (app.plasma.to) handle this correctly

This is blocking all retail users from sending
USDT0 on Plasma Mainnet via Trust Wallet
without first acquiring XPL tokens — which
defeats the purpose of Plasma's zero-fee
stablecoin transfer feature.
