⚡ Solidity VS Code Snippets – Smart Contract Boilerplate This collection of Visual Studio Code snippets is designed to supercharge your Solidity smart contract development. Quickly scaffold common patterns like contract skeletons, modifiers, access control, and ERC20 interactions using simple prefix shortcuts.

🔖 Snippets Overview 🧱 Contract Structure Prefix Description contract Basic contract skeleton with constructor constructor Constructor with immutable owner setup onlyowner Access control modifier (onlyOwner) fonlyowner Function with onlyOwner modifier
🧩 Functions Prefix Description fpub Public function template fext External function fint Internal function fpriv Private function fview View function fpure Pure function fpay Payable function freceive Receive function (ETH fallback) ffallback Fallback function fmod Function with modifier
🔐 Access & Errors Prefix Description error Declare custom Solidity error revert Revert using a custom error
🧾 Events Prefix Description event Event declaration emit Emit an event
🤝 Interfaces & ERC20 Prefix Description interface Interface definition erc20reads Read helper functions for ERC20 (balance, allowance) safetransfer ERC20 token transfer snippet
🧮 SafeMath (for older Solidity) Prefix Description safemath Example using SafeMath lib
🔍 Example Usage Contract Skeleton (contract)
solidity
// SPDX-License-Identifier: MIT pragma solidity ^0.8.19;
contract MyContract {
address public owner;
constructor() {
owner = msg.sender;
}
}
Only Owner Modifier + Function (onlyowner + fonlyowner)
solidity
modifier onlyOwner() { require(msg.sender == owner, "Not owner"); _; }
function updateValue(uint256 _value) public onlyOwner { // logic here } ERC20 Read (erc20reads)
solidity
IERC20 public token;
function balanceOf(address user) external view returns (uint256) { return token.balanceOf(user); }
function allowanceOf(address owner, address spender) external view returns (uint256) { return token.allowance(owner, spender); } 🤝 Contribution Want to expand this collection? PRs and suggestions welcome:
Add common patterns (Ownable, Pausable, etc.)
Add advanced templates (upgradable contracts, interfaces)
