Scripts

In order to read data from a contract, you need to execute a script.

Like transactions, scripts are separate from the contract layer, and are written in different files.

Scripts always look like:

cadence

		
			access(all) fun main() {
  
}

Example Contract & Script

cadence

		
			// Contract file: Counter.cdc
// Deployed to 0x01
access(all) contract Counter {
   access(all) var count: Int

   access(all) fun increment() {
      self.count = self.count + 1
   }

   init() {
      self.count = 0
   }
}

cadence

		
			// Script file: get_count.cdc
import Counter from 0x01

access(all) fun main(): Int {
   return Counter.count
}
