Solidity compiler optimization in Blockchain / Solidity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to enable compiler optimization in Solidity.

Blockchain / Solidity

pragma solidity ^0.8.0;

contract OptimizedContract {
    // Enable optimization with [1]
}

Drag options to blanks, or click blank then click option'

Aoptimizer: true

Boptimizer = true

Coptimization = true

Doptimize = true

Attempts:

3 left

💡 Hint

Common Mistakes

Using '=' instead of ':' in the optimizer setting.

Using incorrect keywords like 'optimization' or 'optimize'.

In Solidity, compiler optimization is enabled in the configuration using 'optimizer: true'.

2fill in blank

medium

Complete the code to set the optimizer runs to 200.

Blockchain / Solidity

pragma solidity ^0.8.0;

contract OptimizedContract {
    // Set optimizer runs to [1]
}

Drag options to blanks, or click blank then click option'

Aruns = 100

Bruns: 100

Cruns = 200

Druns: 200

Attempts:

3 left

💡 Hint

Common Mistakes

Using '=' instead of ':' for runs.

Setting runs to 100 instead of 200.

The optimizer runs are set using 'runs: 200' in the compiler configuration.

3fill in blank

hard

Fix the error in the optimizer configuration line.

Blockchain / Solidity

optimizer: [1] true, runs: 200

Drag options to blanks, or click blank then click option'

A==

B:

C=

D=>

Attempts:

3 left

💡 Hint

Common Mistakes

Using '=' or '==' instead of ':'.

Using '=>' which is not valid here.

The correct syntax uses a colon ':' to assign values in Solidity compiler settings.

4fill in blank

hard

Fill both blanks to complete the optimizer configuration object.

Blockchain / Solidity

{ optimizer: [1], runs: [2] }

Drag options to blanks, or click blank then click option'

Atrue

Bfalse

C200

D100

Attempts:

3 left

💡 Hint

Common Mistakes

Disabling optimizer by setting false.

Setting runs to 100 instead of 200.

The optimizer is enabled with 'true' and runs set to 200 for better optimization.

5fill in blank

hard

Fill all three blanks to complete the Solidity compiler optimization settings.

Blockchain / Solidity

settings = { optimizer: [1], runs: [2], details: { [3]: true } }

Drag options to blanks, or click blank then click option'

Afalse

B300

Cyul

Dtrue

Attempts:

3 left

💡 Hint

Common Mistakes

Setting optimizer to false disables optimization.

Using runs less than 300 for this example.

Missing 'yul' detail option.

Optimizer is enabled (true), runs set to 300 for more optimization, and 'yul' enabled in details for advanced optimization.
