Confirm Transaction

Review the fees, then confirm:

Bash

curl -X PUT https://api.neutron.me/api/v2/transaction/c7d8e9f0-1234-5678-9abc-def012345678/confirm \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN"

After confirmation, Neutron broadcasts the USDT transfer on-chain.

Fee Options

The deductNetworkFeesFromDest flag controls where fees come from:

Setting	Behavior	Recipient gets
false (default)	Fees deducted from your wallet balance	Full amount
true	Fees deducted from the sent amount	Amount minus fees

Example: Sending 100 USDT with 1.50 total fees:

• false → Recipient gets 100 USDT, you pay 101.50 total
• true → Recipient gets 98.50 USDT, you pay 100 total

Transaction States

Notes

• No KYC required for stablecoin sends. KYC is only needed for fiat payouts to bank accounts.
• TRON USDT transfers typically confirm within seconds to a few minutes.
• Double-check the destination address — on-chain transfers are irreversible.
• Ensure sufficient balance to cover the amount plus fees (unless using deductNetworkFeesFromDest).
