{% hint style="info" %} Note: use the max withdrawable query to determine the max amount you can withdraw for a given spot product. {% endhint %}

Rate limits

With spot leverage: 60 withdrawals/min or 10 withdrawals every 10 seconds per wallet. (weight = 10)
Without spot leverage: 30 withdrawals/min or 5 withdrawals every 10 seconds per wallet. (weight=20)

Request Parameters

Parameter	Type	Required	Description
tx	object	Yes	Withdraw collateral transaction object. See Signing section for details on the transaction fields.
tx.sender	string	Yes	Hex string representing the subaccount's 32 bytes (address + subaccount name) of the tx sender.
tx.productId	number	Yes	A spot product ID to withdraw from.
tx.amount	string	Yes	The amount of the asset to withdraw, denominated in the base ERC20 token of the specified product e.g: USDT0 (product=0) has 6 decimals whereas wETH (product=3) has 18. See Signing section for more details.
tx.nonce	string	Yes	This is an incrementing nonce, can be obtained using the Nonces query.
signature	string	Yes	Hex string representing hash of the signed transaction. See Signing section for more details.
spot_leverage	boolean	No	Indicates whether leverage should be used; when set to `false` , the withdrawal fails if the transaction causes a borrow on the subaccount. Defaults to `true`.

Signing

{% hint style="info" %} See more details and examples in our signing page. {% endhint %}

The solidity typed data struct that needs to be signed is:

struct WithdrawCollateral {
    bytes32 sender;
    uint32 productId;
    uint128 amount;
    uint64 nonce;
}

sender: a bytes32 sent as a hex string; includes the address and the subaccount identifier.

productId: a uint32 that specifies the product you’d like to withdraw collateral from; must be for a spot product.

amount: the amount of asset to withdraw, sent as a string. Note that this is different from the amounts provided in transactions that aren’t depositCollateral. This is the raw amount of the ERC20 token you want to receive, i.e. if USDT0 has 6 decimals and you want to withdraw 1 USDT0, specify 1e6; if wETH has 18 decimals and you want to withdraw 1 wETH, specify 1e18. Use all products query to view the token address of the corresponding product which can be used to determine the correct decimals to use.

nonce: the tx_nonce. This is an incrementing nonce, can be obtained using the Nonces query.

{% hint style="warning" %} Note: for signing you should always use the data type specified in the solidity struct which might be different from the type sent in the request e.g: nonce should be an uint64 for Signing but should be sent as a string in the final payload. {% endhint %}
