# Main Event: National Showdown
> Overview of the Aster & 0x1 partnership Trading World Cup.
Aster and 0x1 are teaming up to bring the National Showdown season of the Trading World Cup to life.
Traders represent their countries through national teams, while followers boost team volume and share in team rewards.
The competition runs for a fixed season window with a generous prize pool.
## At a glance
Korea vs Japan.
All participating traders start with a 5,000 USDT trading principal and are scored on the net PnL they generate on Aster perpetual futures during the season window.
The winning country is determined by the combined PnL of every trader on each national team.
22 official national traders (11 per country).
On top of that, any Aster user who wants to support Korea or Japan can register as a backup trader and join the competition.
General users can also participate through mirror trading and earn a variety of rewards.
Start : 6th May 9:00 am UTC+9
End : 5th June 11:59 pm UTC+9

* **Side events:** Starting from 100,000 USDT (uncapped progressive prize pool), with the 0x1 Point Campaign running throughout the season.
## National team structure
Each national team is made up of pre-selected official representatives plus traders who voluntarily register to support their country.
Pre-selected national team traders who officially represent their country.\

They are chosen based on past Aster trading performance, consistency, volume, and influence. They play a critical role in promoting the competition and are expected to carry the primary weight in the country score calculation.
Choose the country you want to support, register, and contribute your PnL to that national team.
High-performing backup traders can challenge official national team standings on the leaderboard.
See the [Backup Traders](/en/partnership/open-teams) page for registration and eligibility.
## How scoring works
On the official start date and time, all registered teams become active. Only trades placed after the start time count toward the season score.
Each participating trader's realized PnL on Aster perpetual futures is tracked in real time. The 0x1 leaderboard surfaces team and country standings as the season progresses.
Positions held before the season starts will be excluded from the score PnL calculation.
The participating account must not hold any open positions at the time the competition starts.
\
* Clear the open positions on the Aster account you registered with, then join.
* Use a sub-account of the Aster account you registered with.
* Sign up for a new Aster account and register with it.
Mirror trading volume from followers who join a national trader's team is added to that team's total trading volume. — See [Rules](/en/partnership/rules) for the volume minimum.
On the official end date and time (TBA, UTC), scoring freezes.
Final standings are calculated from net PnL over the full season window. Trades executed after the close — or positions left open at the end of the season — do not count toward the score.
(During the competition, every trader may deposit only **once per account, capped at 5,000 USDT**. Any account caught making additional deposits to trade will be reset to a 0 score and lose prize eligibility. \*\*If you get liquidated and re-deposit, only your previous score is reset to 0. \*\*)
The prize pool is distributed to teams and individual participants based on final standings. Distribution is on-chain and claimable from the 0x1 dashboard.
## How to participate
You can join as a trader in the National Showdown or as a follower in the side events.
1. If selected for a national team, you will be contacted directly by the 0x1 or Aster team before the season opens.
2. To join as a backup trader, register at [https://0x.one/event/kr-vs-jp](https://0x.one/event/kr-vs-jp) once registration opens.
3. Once the season starts, trade as usual on Aster — your on-chain activity is captured automatically.
1. Sign in to [Asterdex.com](http://Asterdex.com) and deposit funds into your Aster account.
2. Sign in to [0x.one](http://0x.one), then pick a participating team to join from the Event tab.
3. Mirror at least one mirror trader from that team. Your mirrored volume is added to the team's qualifying volume.
4. You earn participation rewards proportional to the volume you contributed, on top of your normal mirror trading PnL.
Follower rewards are paid in addition to the regular PnL you earn from following mirror traders. Joining a team does not change your fee structure or risk settings.
## Prize distribution rules
* The prize pool is awarded to participants from the winning country.
* The winner is determined by the country with the higher combined team PnL.
* Only participants with positive PnL are eligible to claim.
* Rewards are distributed within the winning team based on each individual's PnL contribution share.
