Contracts are sets of tasks that you can complete to earn points and compete for the Top Executor reward.
Contracts vary in duration and the tasks they contain. There are 5 sections in the Contracts tab: 3-hour, 8-hour, 21-hour, 2-day, and 1-week contracts. Each contract has its own set of tasks. You can see the list of tasks for a particular contract and the number of points by tapping the "Missions" button.
Contracts run for the allotted time and then restart. As you complete tasks and earn points, you fill up your progress bar and unlock chests containing coins, crypto chips, and other useful resources. The rewards you receive for completing tasks vary depending on your league. Note that your championship rank isn't linked to Contracts and doesn't affect your progress there.
After each match, you can see your contract progress and how many points you have earned. You can increase the number of points you receive by purchasing the Contracts Booster, which will allow you to earn many times more points and progress faster.
Once you have collected the maximum number of points on the contract progress bar, you will start competing for the title of Best Executor and a special reward.
Top players and 5% and 10% of the top executors will receive special rewards. At the end of the contract you will see a window showing the result and you will be able to collect the reward you have earned.
A contract cycle lasts 28 days. After that, the Contracts will be completely closed and you will have one more day to spend the crypto chips you have earned. Please note that the crypto chips change at the start of each new contract cycle, so it is important to spend them in the allotted time before they expire.
From time to time you may also have access to Personal Orders, which allow you to earn additional rewards. They are different from contracts: you cannot receive cryptochips for completing them. In addition, they will not be closed at the same time as other contracts. You can't compete with other players in Personal Orders, as everyone's tasks are different.
