Tenderly is an open-source, web-based platform for debugging and testing smart contracts.
It supports popular blockchain networks such as Ethernet, Binance Smart Chain, and Polygon.
With Tenderly, you can create custom, contextual debugging views for your smart contracts.
The platform integrates with popular development environments like Truffle, Web3.js, and VS Code.
Tenderly’s Replayer feature allows you to rewind, fast-forward, or replay your smart contract’s execution.
You can visualize transaction flows, logs, and state changes using Tenderly’s interactive debugging views.
The platform offers a collaborative debugging feature, enabling multiple developers to inspect and debug smart contracts together.
Tenderly provides detailed debugging information, including error messages, stack traces, and memory dumps.
It also supports debugging multi-chain and cross-chain interactions.
Tenderly’s open-source design enables community contributions and custom integrations with your favorite development tools.
Guide to Using Tenderly for Debugging Smart Contracts
Introduction
Debugging smart contracts can be a daunting task, especially for developers new to the blockchain space. Tenderly is a powerful tool that makes it easier to identify and fix issues in smart contracts. In this article,
Getting Started with Tenderly
Tenderly is a web-based platform that provides a comprehensive suite of tools for smart contract development, testing, and deployment. Its debugging capabilities are particularly useful, as they allow developers to identify and fix issues quickly and efficiently. For example, Tenderly’s debugger allows developers to set breakpoints, step through code, and inspect making it easier to identify the root cause of issues.
Here are the steps to get started with Tenderly:
Create an account on the Tenderly website
Connect your Ethereum wallet to Tenderly
Import your smart contract code
Start debugging using the Tenderly debugger

Use the Deployer to deploy smart contracts to the Ethereum mainnet or testnet
Common Issues in Smart Contract Development
Smart contract development can be complex, and issues can arise during development. Some common issues include:
Issue
Description
Solution
Reentrancy attacks
Occur when a contract calls another contract, which then calls back to the original contract
Use the Tenderly debugger to identify and fix reentrancy vulnerabilities
Unsecured use of tx.origin
Can lead to phishing attacks
Use the Tenderly simulator to test smart contracts and identify vulnerabilities
Use of uninitialized variables
Can lead to unexpected behavior
Use the Tenderly debugger to identify and fix issues with uninitialized variables
Incorrect use of gas
Can lead to unexpected behavior
Use the Tenderly monitor to track smart contract activity and identify issues with gas usage
Best Practices for Smart Contract Development
Smart contract development requires careful planning and execution. Here are some best practices to keep in mind:
Use a secure programming language, such as Solidity or Vyper
Use a reputable development framework, such as Truffle or OpenZeppelin
Use a testing framework, such as Mocha or Chai
Use a Debugger to identify and fix issues
Use a Simulator to test smart contracts in a simulated environment
