Simple Editor Guide

Simple Editor Features

1

Single-file Contract Editing

Edit one contract at a time with real-time syntax highlighting and error checking

2

Sample Contract Templates

Choose from pre-built contract templates for common use cases (tokens, NFTs, storage)

3

Auto-validation

Get instant feedback on syntax errors, security issues, and gas optimization

4

Security Scoring

View your contract's security score and specific vulnerability warnings

5

One-Click Deployment

Deploy directly to a supported testnet without configuration complexity

Workflow Guide

1

Step 1: Select a template or create custom code

Begin with a sample contract or write your own from scratch

2

Step 2: Validate your contract

Check for syntax errors and security vulnerabilities before compilation

3

Step 3: Compile to bytecode

Transform your Solidity code into bytecode ready for deployment

4

Step 4: Deploy to testnet

Push your contract to a supported testnet with a single click

5

Step 5: Interact with your contract

Connect to your deployed contract to execute functions and view state

Tip: For simple contracts or learning, the Simple Editor provides everything you need. Switch to Advanced IDE for complex multi-file projects.

Tips

1

Use Solidity version 0.8.0 or later for built-in overflow checks

2

Avoid using tx.origin for authentication - use msg.sender instead

3

Always check return values from external calls

4

Follow the checks-effects-interactions pattern to prevent reentrancy

5

Use specific visibility modifiers for all functions and state variables

6

Limit gas consumption in loops to prevent DOS attacks

7

Consider using OpenZeppelin's battle-tested contracts

8

Add comprehensive test coverage before deployment

9

Document your code with NatSpec comments

10

Use SafeMath for versions prior to Solidity 0.8.0
