tl;dr: Play Fair.

Yesterday the 23rd of March, the second wave of EthCC tickets went on sale powered by Unlock Protocol.

Did you say EthCC Tickets?

The tickets are stored on the Polygon blockchain as keys which can be checked at the entrance of the venue. Conference attendees can purchase the tickets with credit card with stripe or via USDC tokens.

Those tickets are not anonymous for the organizer, the Ethereum France team has to collect information from the purchaser (name, surname and email) so as to comply with the venue insurance and sanitary security guidelines.

As a result, the tickets have in their metadata an identifier for Unlock Protocol to interpret and validate. This information will be verified on site the day of the event along with the validity of the ticket.

The tickets are also Non Transferable and calling the transfer function will throw an error and revert. Nevertheless, a dedicated team at EthCC is here to help and handle ticket transfers between attendees in an effort to avoid scams and heavy speculation.

Thursday the 23rd, 308 tickets were sold in 3 minutes

  • 10 tickets were sold via credit cards
  • 98 tickets were sold via USDC
  • 200 tickets were scalped in USDC by a single user

Scalper (definition): noun US informal, someone who buys things, such as theater tickets, at the usual prices and then sells them, when they are difficult to get, at much higher prices:
A scalper offered me a $20 ticket for the concert for $90.

The Cambridge Dictionary)

Unfortunately for the scalper, the tickets are invalid and have no compatible metadata whatsoever. Since the tickets can not be transferred, the scalper created a dedicated Gnosis Safe contract for every ticket scalped and has created a collection on Open Sea to try to resell them (please report it!). Even if the ownership of a Gnosis Safe can be transferred, the ticket it contains is invalid so don’t attempt to buy one of them. Moreover, since regular tickets are not transferable, listing them on Open Sea is useless and attempts to buy them will fail (See this early bird purchaser trying to resell for 5 ETH).

Note to the scalper: if you are reading this, thank you for the 200 metadata-less and untransferable NFT you purchased from us. Should you like to chat, feel free to send us a transaction from your address with a mean of communication you prefer in the extra data field.

When will more tickets be available?

We are currently targeting to put more tickets for sale in the next weeks. The best way to hear about the date is to follow and activate the notifications of our twitter account @EthCC!

As 200 invalid tickets were emitted in this wave, 200 more tickets will be added to the waves to come. In the meantime, the first batch of speakers will shortly be announced.

What if I can’t find a ticket at all?

We have been witnessing the growth of our ecosystem through the Ethereum Community Conference for 6 years now and we are sorry not to be able to scale EthCC as fast. We reschedule, resize and retarget every year, with one principle at heart: a non commercial event that aims at being at cost, keeping the ticket price as low as possible and accessible for everyone. Nevertheless, side-events do scale very well during the EthCC. Last year there were 60 community led events in Paris during the whole week and you should plan your trip to Paris just for them. EthCC also has a volunteer program, a foreign student program, and speaker applications are open (here you go!).

Bon baisers de Paris!
