  • Testing & Debugging: Utilize Thor Solo for rapid local testing and debugging.
  • Security Audits: Apply best practices and checklists for secure contract design.
  • Use Case: Develop a new ERC-20 token on VeChain, set up its testing environment, and ensure it follows security best practices before deployment.

Quick Start

Use the smart-contract-development skill to create a new ERC-20 token contract using Hardhat.

Frequently Asked Questions about smart-contract-development

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up Hardhat for Solidity smart contract development on VeChainThor?▼

Set up Hardhat for VeChainThor smart contracts by configuring the environment with the VeChain SDK, ensuring correct EVM target compatibility and network parameters to streamline Solidity compilation and deployment.

What is the best way to test ERC-20 and ERC-721 contracts locally before deploying?▼

The best way to test ERC-20 and ERC-721 contracts locally is utilizing Thor Solo for rapid debugging. This allows you to validate token models and transaction logic safely before mainnet deployment.

Can I implement upgradeable smart contracts on the VeChainThor blockchain?▼

Yes, you can implement upgradeable smart contracts on VeChainThor. The development process supports upgradeable patterns alongside gas optimization and security auditing to ensure safe contract mutability.

How do I perform a security audit for Solidity contracts on VeChain?▼

Perform a Solidity security audit on VeChain by applying dedicated best practice checklists for secure contract design. This process validates access controls and token logic to ensure safe mainnet deployment.

Does generating ABI codegen for VeChainThor require specific Hardhat configurations?▼

Generating ABI codegen for VeChainThor requires specific Hardhat configurations to align with VeChain-specific correctness for network and EVM targets. This ensures the compiled interfaces match the blockchain's token models.

Why do I need to use Thor Solo instead of standard Hardhat network for local testing?▼

You need Thor Solo instead of standard Hardhat network for local testing to ensure VeChain-specific correctness regarding network gas models and transaction execution. Thor Solo accurately simulates the VeChainThor environment.
