Returns the per-cryptocurrency float balance for the authenticated main account.
The float is a crypto buffer held in the Binance main account that funds security repayments and security-based loan closures during reckoning. The buffer is consumed during reckoning and then replenished back to its baseline once the reserved security is unwrapped to its native form.
Use this endpoint to monitor whether the buffer is sufficient to cover pending security operations. If the float balance drops below the expected baseline, additional crypto must be deposited before the next reckoning can process security repayments or closures.

What is the float?The float is a crypto buffer you pre-fund to Block Earner to cover security repayments, security-based loan closures, and automatic repayments before reckoning to lock in the rate at the time of repayment. Block Earner manages the buffer: it is consumed at the time of repayment triggered and then replenished back to its baseline once the next reckoning is completed.
This endpoint returns the current per-cryptocurrency float balances Block Earner holds on your behalf. Use it to monitor whether the buffer is sufficient to cover upcoming security operations. For each cryptocurrency the response returns:
floatBalance— the current float buffer available for security operations. This is the field to monitor to assess whether you have enough float in place to cover security repaymenttotalBalance— the total crypto balance before any pending transaction adjustments. This field is just as an information after reckoning what level of float balance it will be replenish toupdated— when the float balance was last recalculated.
Insufficient floatWhen a security repayment (
POST /sub-account/loans/{loanId}/repayments/security)
or a security-based closure (POST /sub-account/loans/{loanId}/close/security)
requests more security crypto than the float can cover, the request is
rejected with the error codeINSUFFICIENT_FLOAT_BALANCE. Prefund Block Earner to replenish the float before retrying.
