HitBTC will support the next stage of Ethereum (ETH) Constantinople hard fork

Dear traders,

HitBTC will support the next stage of Ethereum (ETH) Constantinople hard fork. The upgrade is estimated to take place on 28 February 2019 after being postponed due to the need for further investigation of potential risks identified by ChainSecurity (https://blog.ethereum.org/2019/01/15/security-alert-ethereum-constantinople-postponement/). The fork will happen approximately on block #7,280,000. Two protocol upgrades (Constantinople and St. Petersburg) will need to occur on the same block number in order to fix issues on various Ethereum test networks.

If you are holding Ethereum on HitBTC account, you don’t have to do anything, as we will handle all the technical requirements involved with the upgrade, please be assured that the funds will be safe at all times.

You can monitor the network upgrade in real time at http://forkmon.ethdevops.io/

The first stage of the BTT Airdrop to TRON (TRX) holders

We have successfully supported the first stage of the BTT Airdrop to TRON (TRX) holders. In total, 10,890,000,000 BitTorrent (BTT) are currently being distributed for the next 12 months, corresponding to 1.1% of the total supply. All funds transferred to us from the BitTorrent Foundation were distributed among the TRX holders.

The current ratio of BTT airdrop is 1 TRX = 0.109768 BTT. The next distribution stage should take place around the 11th of the next month. We will continue to support further distribution steps in accordance with the BTT Airdrop plan.

HitBTC will support the upcoming Ethereum (ETH) Constantinople hard fork

Dear traders,

HitBTC will support the upcoming Ethereum (ETH) Constantinople hard fork. It includes five separate Ethereum Improvement Proposals (EIPs) and is taken as a step to transit from the Proof of Work (PoW) protocol to a more energy efficient Proof of Stake (PoS) consensus algorithm. As expected, this update will make the ETH network faster and less costly to operate.

Please leave sufficient time for deposits to be processed in full prior to the block height shown below. We will handle all the technical requirements involved for all users holding Ethereum in their HitBTC accounts, please be assured that funds will be safe.

We have always supported all the significant forks, endorsed by the community and oriented towards improving the blockchain ecosystem. We were amongst the first to support BCH and ETC forks, and users can be assured that their accounts will be credited for the different forks if any occurs.

For more details, please refer to the Ethereum meeting at: bit.ly/2BWTJPH

Hard Fork Block Height: 7,080,000

Estimated Time: Between 2019/01/14 and 2019/01/18

Please follow our blog for more news and official announcements!

We thank you for your support and for using our service.

TUSD smart contract address update

Dear traders,

TUSD (TrueUSD token) will be upgrading its smart contract at 3:00 UTC of January 4th. The new TUSD address will be 0x0000000000085d4780B73119b644AE5ecd22b376.

To upgrade the contract, TrueUSD will use their DelegateERC20 feature. The old contract will continue to function with zero downtime; however, after the upgrade, ERC20 events will only be emitted from the new contract. This means that HitBTC and other exchanges and apps that rely on ERC-20 events will upgrade to the new contract address. Specifically, we rely on Transfer events to process transactions.

In other words, both TUSD contracts, old and new, will keep working and affect the same balance entities; but each contract will emit its own Transfer events, and we cannot automatically process payments from two different contracts for the same currency.

What does this mean for users?

  1. If you use your own ETH wallet, please update the contract address you use to make TUSD transactions. Check TUSD’s official announcement if you have any questions about this.
  2. If you use a 3rd party service, please ask your service provider to upgrade the TUSD contract they use.
  3. If you cannot find a deposit you made, check whether you may have used the old address by accident. If so, please contact their support center. No user’s balance should be affected because of this upgrade.
  4. There might be a deposits/payouts downtime of 15 minutes on our side; we need to make sure that the contract swap went smoothly.

Remember: the new TUSD address is 0x0000000000085d4780B73119b644AE5ecd22b376.

Thank you for reading, and happy trading!

HitBTC 2018 Review

2017 was the year of the amazing bull run; the year the value of Bitcoin grew 1,950%; from $974 to $20,000. Not the year of mass adoption, but certainly the year that blockchain and cryptocurrencies crossed over into mainstream awareness. And the latter is – though admittedly less exciting – a prerequisite for the first.

But that was last year. Today, as end-of-year analyses begin to populate blogs and news portals, we search for an appropriate title for 2018. The year of the disquieting bear market? The year of regulatory backlash? The year of correction?

We cannot claim to have the definite title for 2018. But, in this post, we do look back on some of the events that sculpted the crypto financial year, reflect on what awaits us in 2019, and leave any title searching up to you. What will the year 2018 go down as in crypto history?

System Updates – Lot Size Changes

To allow existing orders to support the new lot size granularity, we will be making an update to every order currently active in each market.

To make this update and guarantee correct execution behaviour for the orders during the update, we will be canceling the current orders and booking a replacement via an atomic transaction.

All order parameters will be preserved through the update and users will not see any behavioural differences in order execution or future updates to these orders.

Users will be notified of this cancel/replace transaction through an Execution Report for each order. The cancellation of the original order and the replacement will also be visible to users querying their order history via API or via the Cancelled and Filled Orders widget.

These changes have already been made successfully for all EOS markets. For orders in these markets, users will have seen the behaviour described above and should have already received their Execution Reports for orders.

The final phase of the update, which will allow users to execute orders in the new lots sizes, will take place December 29, 17.30 UTC.
The new lot sizes and price steps will be:
LTC/BTC: lot 10-3 LTC, step 10-7 BTC
LTC/ETH: lot 10-3 LTC, step 10-6 ETH
LTC/USDT: lot 10-3 LTC, step 10-4 USDT
DOGE/BTC: lot 10 DOGE, step 10-10 BTC
DOGE/ETH: lot 10 DOGE, step 10-8 ETH

During the final phase of the update, pairs under maintenance will be unavailable for approximately 5 min. You will not be able to place or cancel orders on these pairs during this short maintenance period. API users might also receive a “2001: Symbol not found” response on these pairs during this period.

Should you not see this behaviour or if you have any questions or concerns – please reach out to our support team.

HitBTC is updating its lot size

Dear Traders,

We have been aware for some time that our users would like access to more granular lot sizes than are currently available in order to allow trading in a smaller size.

So, by popular demand, we are happy to announce changes to bring lot sizes for all instruments in-line with market standards. This should allow for much easier market access for all our users, improving liquidity across the platform.

We expect to release changes to all pairs over the next few days to support these smaller lot sizes. This is a two-step process that users should be aware of, as it will have a temporary impact on the visibility of markets on the platform.

New lot sizes for each pair can be found below.

Step 1:

Users should note that in preparation for these changes markets will need to be temporarily taken down from the platform:

  • During these works, users will not be able to view the market that is being configured at that time, or place/cancel/update orders on that specific market
  • No orders will be canceled during the works
  • There will be no visible change to the platform after this first step

The expected period of maintenance for each market is posted below and is expected to be no more than 10 mins for the most active markets. Any changes to these times will be posted here if necessary.

Step 2:

Each relevant pair will then need to be taken offline, with an expected downtime of no more than 5 minutes per pair:

  • Pairs will be taken offline in the order deleted below
  • During this time users will not be able to view the pair or place/cancel/update orders for this pair
  • No orders will be canceled during this update
  • After the change, the pair will support the new lot sizing
  • All orders will be kept at their current absolute size

For your convenience, we will inform you of the exact pairs and markets 3 hours and 15 min before the procedure via Twitter and Web notifications.

Expected works schedule:

  1. 27 December, between 09.00 UTC and 15.00 UTC — maintenance on EOS markets for 15 minutes.
  2. 28 December, between 09.00 UTC and 15.00 UTC — maintenance on BTC, ETH, USDT markets for approximately 5 minutes.
  3. 29 December, between 15.00 UTC and 21.00 UTC — maintenance on following pairs for approximately 10 minutes:
    • LTC/BTC
    • LTC/ETH
    • LTC/USD
    • DOGE/BTC
    • DOGE/ETH
