Create a v2 transfer

Creates a v2 payout transfer and returns a hardcoded deposit address for the requested source_token/source_network combination. Unlike v1, the deposit address is fixed — no provider API call is made at initiation time.

v2 differences from v1:

USDC only — USDT transfers must use POST /api/payouts/transfer.
No expiry — there is no time window to send funds. The transfer remains open until you send USDC and call POST /api/payouts/transfer/v2/confirm-transfer.
Two-phase confirmation — after sending USDC on-chain, you must call POST /api/payouts/transfer/v2/confirm-transfer with the transfer_id and tx_hash to trigger the payout pipeline. The platform matches the deposit to your transfer using the provided transaction hash.

Wallet compliance screening (conditional, per-account): when compliance screening is enabled for your account (the default), wallet_address is required, must be an EVM address (0x + 40 hex chars), and is screened before any other processing. A wallet that fails screening is rejected with 403. When screening is disabled for your account, wallet_address stays KYC-conditional (see below) and Solana addresses are accepted.

KYC wallet verification (conditional, per-account): if your account requires KYC verification, wallet_address is required and must be a KYC-verified wallet or the request is rejected with 403 (verify at kyc.madhousewallet.com); if KYC is not enabled for your account, wallet_address may be omitted (unless compliance screening requires it).

Workflow:

GET /api/payouts/quote → save quoteId.
POST /api/payouts/transfer/v2 with quote_id, amount, recipientId, source_network (and wallet_address — required if compliance screening or KYC is enabled for your account) → receive deposit_address and transfer_id.
Send exactly amount USDC to deposit_address on source_network.
Call POST /api/payouts/transfer/v2/confirm-transfer with transfer_id and the on-chain tx_hash.
The platform detects the deposit and automatically initiates the fiat payout — email confirmation sent.

Supported networks for v2 (USDC only): base, solana, polygon, arbitrum, avalanche, ethereum.

Rate limit: 20 requests/minute.

number

required

USD amount to transfer (max 2 decimal places, must match the quoted amount ±$0.01).

Example:

500

recipientId

integer

Example:

12345678

source_token

enum<string>

base,

solana,

polygon,

arbitrum,

avalanche,

wallet_address

string

The address on source_network that will send USDC to the deposit address. Conditionally required: required if compliance screening or KYC verification is enabled for your account; may be omitted otherwise (stored and returned as an empty string). When compliance screening is enabled (the default), it must be an EVM address (0x + 40 hex chars) and is screened before processing — Solana addresses are rejected. When screening is disabled, both EVM (0x + 40 hex chars) and Solana (base58, 32–44 chars) addresses are accepted; if KYC is enabled it must be a KYC-verified wallet.

Example:

"0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B"

keep_recipient

boolean

When true, the recipient is not automatically deleted after the transfer reaches a terminal state. Defaults to false.

Example:

false

customer_email

string<email>

Email address to receive payout status notifications (sent and failed). If omitted, notifications are sent to the authenticated account's email address.

Example:

"customer@example.com"

Response

Transfer created — deposit address returned

transfer_id

string

required

Unique transfer reference. Use this ID with POST /api/payouts/transfer/v2/confirm-transfer.

Example:

"507f1f77bcf86cd799439011"

required

The address to send USDC to on source_network. This is a fixed offloader wallet address.

Example:

"0xBC91bCF38e3c0DE1E3fD0cF50Be7c0e52D55D00e"

source_token

string

required

Token to send (always usdc on v2).

Example:

"usdc"

Target payout currency.

Example:

"EUR"

wallet_address

string
