Hi, dear, problem with signature for futures
query_string = "&".join([f"{k}={v}" for k, v in sorted(kwargs.items())])
query_string = self.api_key + timestamp + query_string
signature = hmac.new(self.api_secret.encode('utf-8'), query_string.encode('utf-8'), hashlib.sha256).hexdigest()

i tried change:
signature = hmac.new(query_string.encode('utf-8'), self.api_secret.encode('utf-8'), hashlib.sha256).hexdigest()

but same, checked everything is ok i dont know what can be wrong?

The MEXC Futures API is currently not operational.
Information on API availability can be found here -> https://t.me/MEXCAPIsupport

what endpoints you were having problems with? When I first came across this message I just concluded that in the lines 151-162 of base.py the api_key and api_secret were only being passed when kwargs contained params/json. Add an else statement and remove the kwargs from the self.sign call. Or something like this ` if kwargs.get('params'):
kwargs['params'] = {k: v for k, v in kwargs['params'].items() if v is not None}

    if self.api_key and self.api_secret:
        # add signature
        timestamp = str(int(time.time() * 1000))
        kwargs['headers'] = {
            "Request-Time": timestamp,
            "Signature": self.sign(timestamp) if not kwargs.get('params') else self.sign(timestamp, **kwargs['params'])
        }

    response = self.session.request(method, f"{self.base_url}{router}", *args, **kwargs)`

It's mexc, API futures not supported( thanx
