After the API key and sub-account are connected to a challenge, they must not be edited, deleted, replaced, or disconnected without Era Trade approval.
One sub-account = one challenge. If the key expires or the connection is lost, restore the connection for the same sub-account instead of reusing an old key for another challenge.
If the API key expires or the connection is lost unintentionally, the account may be temporarily moved to pending/reconnect until a new key is connected and approved.
Trades placed while a valid API connection is missing may not be counted. Intentional disconnection, modification, or interference with API access may lead to immediate account closure.
