Initiate Off-Ramp Withdrawal
Sweeps USDC from a customer SCW to the Rach treasury via an ERC-4337 UserOperation on Polygon PoS. Once USDC is confirmed on-chain (CRYPTO_RECEIVED), Rach disburses XOF to the customer via the specified mobile money network. Monitor status via GET /v1/dashboard/withdrawals/. Status lifecycle: PENDING → SUBMITTED → CRYPTO_RECEIVED → COMPLETED.
