Send USDT Payment To Escrow Or Destination Address

Initiates USDT transfer from user’s CoinPool wallet to the destination address. Supports both on-ramp (ON_RAMP_BUY) and off-ramp (OFF_RAMP_SELL) orders.

For Off-Ramp Orders:

Transfers USDT from customer’s wallet to escrow address
Used when customer wants to send crypto in-app (no external wallet needed)
Network and destination are determined from order’s escrow details

For On-Ramp Orders:

Transfers USDT from customer’s wallet to their own wallet address
Typically not used (vendor sends USDT after mobile money payment)
Network is detected from customer’s wallet address
Supported for alternative flows or pre-funding scenarios

Security:

Wallet must belong to the order’s customer
Wallet network must match order’s required network
Requires explicit confirmation (confirm: true)
Private keys are decrypted server-side only
