Switcheo TradeHub suffered a chain halt on 8th Feb 2021 at 10:06PM SGT, which was unrelated to separate issue found on the preceding day. This is a post-mortem report for the incident.

Summary

In preparation for allowing trading of futures contracts, oracles for the BTCUSD and ETHUSD index was created on 16th Dec 2020. This meant that validators began submitting votes for prices of these assets every second. However, after the V1.12.0 upgrade in early February, some validators stopped running the oracle service on their subaccounts. Because a supermajority was not present, no oracle results were resolved for an extended period…


Switcheo TradeHub experienced a chain halt yesterday, 7th Feb 2021 at about 10:34:46 UTC on block 7252686. This is a post-mortem report on the incident.

Summary

On block 7131150, a change to the AMM module was introduced through the v1.12 node software upgrade in order to improve Switcheo TradeHub’s AMM quoting logic.

This logic involves an inverse computation of the Constant Value formula, to automatically quote maker orders on the order books based on the liquidity of the corresponding pools.

The root cause of the incident was that an incorrect rounding direction was used when rounding decimals to integers in the…


It’s finally here! Switcheo TradeHub is now accepting deposits and staking.

Before you proceed, here are some important notices.

At this time, a new mnemonic-based Switcheo TradeHub wallet is required. Losing control or access to this wallet will result in loss of all funds. Users who are unfamiliar with securing these types of wallets should not take part in this phase. Support for using Ledger hardware as well as software wallets will be coming soon.

Good day everyone! Switcheo TradeHub is on track to mint its genesis block some time tomorrow, 12 August 2020. The block progression of this sidechain will then be viewable on the (simple but functional) block explorer, Switcheo TradeScan.

Cross Chain Deposits & Staking

Once the sidechain is running, we want to give our engineers ample time to integrate and test that cross-chain transfers operate with the various Layer-1 networks as expected.

Rather than compromising on your first staking experience, we will instead…


As we draw very close to the launch of Switcheo TradeHub, the excitement brewing amongst our team is palpable, even across the vast distances of Zoom calls.

Through a series of three posts over the next few days, we’ll be sharing with you how the Switcheo token (SWTH) will become an even more integral part of our trading ecosystem.

In today’s article, we’ll start off by exploring the new basic mechanics of the token and then touch on the monetary policies that our team is currently proposing.

Staking at our core.

We’ve already revealed that when Switcheo TradeHub launches, SWTH will have a staking…


Hi everyone,

Due to additional stay-home orders in China, the launch of the SWTH redemption program unfortunately has to be be further postponed from 19th Feb 2020 to 6th Mar 2020.

While we understand that the delay duration may be disappointing for some, the team has decided to push the official start date further than what may be necessary in order to avoid having further postponements.

Our original postponement announcement can be found here, and information about this program can be found here.

Thank you for your continued support!

Hi everyone,

Due to the recent outbreak of novel coronavirus, we will be delaying the launch of the SWTH redemption program. The launch timing is affected as physical access to certain assets in Shanghai is required for preparation of the upcoming system. This is currently not possible as on-premise work is not permitted by health regulations until 10th Feb 2020.

In order to give an abundance of time for a smooth launch, we will be postponing the start of the program by one week, from 12th Feb 2020 to 19th Feb 2020.

Please note that the previously scheduled exchange maintenance…
