Connect your Hotcoin account to Synemer
Set up a read-only Hotcoin API key and link your account to Synemer so your USDT-margined perpetual futures trades sync automatically.

What this connection does
Synemer connects to Hotcoin with an Access Key and Secret Key that have Read permission only. Your closed USDT-margined perpetual trades land in one journal without manual entry.
Your credentials are encrypted and only used to read historical trade data.
Before you start
An active Synemer account.
A Hotcoin Access Key and Secret Key with Read permission.
Access to Hotcoin API key management at hotcoin.com.
Create a read-only key in Hotcoin
Log in at hotcoin.com and open API key management. Create a new key and give it Read permission only.
Copy the Access Key and Secret Key. Do not enable Trade or Withdraw. Synemer never needs them.
If Hotcoin lets you bind IPs, allow Synemer's egress IP. Binding is optional, but it limits where the key can be used.
Add the connection in Synemer
In Synemer, open Add connection, choose Hotcoin, and paste the Access Key and Secret Key.
Save the connection. Synemer validates the key on the first sync.
What syncs automatically
Synemer imports filled USDT-margined perpetual orders, rebuilds closed positions, and records fill-level orders. Open positions and account balance are captured too.
Account transfers between Hotcoin account types are tracked as capital flows. Spot trading, options, delivery futures, and inverse contracts are not imported.
History depends on the API window
Hotcoin does not publish a fixed retention window for trade history. Synemer imports what the API serves on the first sync and keeps syncing new orders as they fill.
A position that opened before the available window and closed inside it is rebuilt from the closing fills. Synemer keeps the realized PnL and marks the missing entry as incomplete.
Troubleshooting
A signature or timestamp error usually means the secret is wrong or the system clock is off. Create a new key in Hotcoin and paste both values again.
A permission error means the key lacks Read access. Edit the key in Hotcoin or create a new one.
If Hotcoin returns a rate limit, wait a minute. Synemer retries on the next sync tick.
If the request is blocked by a region or proxy, check the Hotcoin notice in the app. Synemer routes Hotcoin through its EU egress, so a VPN is not required.
If no history appears, confirm that the account traded USDT-margined perpetuals in the available window.
