Dear valued customers, Effective 05:30 Oct 23, 2018 (Central European Time), we will be changing the decimal place precision for XRP futures contracts for better trading experience. Details are as follows: Any trading and other account operations will remain normal and uninterrupted when the adjustment takes place. You are more than welcome to send us an email at futures@OKX.com if you have any suggestions on the price precisions of other contracts.

On-chain deposit logic: Our platform is a centralized exchange, so when you deposit funds to your account address, they will only be credited once it meets the required aggregation conditions. If the amount is too small, the funds cannot be aggregated because the address balance may not be sufficient to cover the miner fees for an on-chain transfer. System management: The minimum deposit amount helps the platform manage asset flows better and prevents system strain caused by small deposits.
