​
Overview

Creates a withdrawal from your available merchant USD balance to a supported on-chain address.
Provide a unique X-Idempotency-Key for each withdrawal attempt so retries do not create duplicate transfers.
Before creating a withdrawal, check Get Merchant Balance and validate the destination chain with List Supported Chains.
Only USDT on POLYGON is withdrawal-enabled right now. Use the token-level metadata from GET /v1/supported-chains to validate supported combinations before submitting a withdrawal.
