⚠️ Erratum on daylight saving time support (DST) ⚠️

2 min readOct 20, 2021


During the preparatory tests for Avalanche, we detected that the Gatekeeper does not support DST.

This feature could not be coded directly in the Gatekeeper because there is uncertainty about the continuity of the DST of the countries concerned.

In our initial design, we planned for the Wasdaq contract owner to update the Gatekeeper.

Following the security audit we performed last August, it appeared that this functionality added a security problem, as the Gatekeeper could be replaced by a malicious contract.

In order to close this loophole and to guarantee a strict security contract on the DeFi, we decided to renounce the Wasdaq contract and to use the current Gatekeeper for good.

A contract already deployed on the blockchain cannot be modified, so we cannot modify the time change for winter time.

Wasdaq trading hours do not change and are always still 1:30 pm to 8:00pm UTC.

For countries that are not affected by Daylight Saving Time, this does not change anything for you.

For countries that do have Daylight Saving Time (you move back one hour from UTC), check your local time to refer to our times (1:30 pm to 8pm UTC. )

And if you’re ever in doubt, our website and social networks always tell you the exact time the Wasdaq market opens.

⚠️ Important information for Europeans about the winter time changeover ⚠️

In Europe the winter time changeover is on October 31, but in the United States it is on November 7.

The Wasdaq has the same trading hours as the Nasdaq, so our winter time changeover is also on November 7. (9:30 am — 4:00 pm NY Time UTC-4)

For a week, the time difference between Europe (UTC) and the United States (UTC-4) will therefore be reduced to 3 hours, instead of the usual 4 hours.

So, during this week, the opening and closing Wasdaq Market for you will be 1 hour earlier.

If you have any doubts, our website shows you the opening and the closing time of the Wasdaq market.
