Transaction Simulation
Tenderly is a full-stack Web3 development platform offering advanced smart contract debugging, simulation, observability, and scalable node infrastructure for EVM-compatible chains.
Overview
Tenderly is a comprehensive Web3 development platform designed to streamline the entire decentralized application (dapp) lifecycle. It integrates development, observability, and infrastructure tools into a single environment, enabling developers to build, test, monitor, and deploy smart contracts efficiently across all major Ethereum Virtual Machine (EVM) compatible chains, Layer 2 solutions, and rollups. The platform replaces traditional public testnets and local nodes with Virtual TestNets—customizable, zero-setup development environments that provide real-time mainnet data and state syncing without requiring code changes.
Key features include a powerful Developer Explorer for granular on-chain data insights, a transaction Simulator to preview transaction outcomes without on-chain execution, and advanced debugging tools offering detailed stack traces and human-readable error messages. Tenderly’s Node RPC service extends beyond standard node providers by offering a scalable, extensible RPC infrastructure that supports high throughput and global availability, with the ability to deploy custom logic and APIs directly within the node.
What sets Tenderly apart is its deep integration of simulation and debugging capabilities with production-grade infrastructure, enabling teams to iterate rapidly and reduce costly on-chain errors. Its collaborative tooling supports team workflows with shared staging environments, real-time monitoring, and alerting for on-chain events. Notable users include MakerDAO, Uniswap Labs, Yearn Finance, and Safe, who leverage Tenderly to optimize development velocity, improve reliability, and enhance user experience. Developers can get started quickly by signing up for free, integrating Tenderly’s Virtual TestNets with popular frameworks like Hardhat or Foundry, and switching RPC endpoints to scale from development to production seamlessly.
The Problem
Web3 developers face fragmented tooling that complicates smart contract development, testing, and deployment. Public testnets are often rigid and unreliable, while standard node providers lack deep insight into transaction execution and debugging capabilities. This fragmentation slows iteration, increases risk of costly on-chain errors, and complicates team collaboration.
The Solution
Key Features
Developer Explorer
Provides decoded, human-readable on-chain data and transaction details for deep insights during development.
Transaction Simulator
Preview exact transaction outcomes without sending them on-chain to reduce risk and improve user confidence.
Gas Profiler
Analyze gas consumption per function call to optimize contract efficiency and reduce costs.
Virtual TestNets Integration
Seamlessly replace local nodes or public testnets with customizable, forkable environments supporting all major EVM chains.
Real-Time Monitoring and Alerts
Set up automated alerts for on-chain events to quickly identify and respond to issues.
Key Strengths
How Developers Use Transaction Simulation
Smart Contract Development and Testing
Developers use Tenderly’s Virtual TestNets and debugging tools to build and iterate on smart contracts with real mainnet data and detailed error insights.
On-Chain Transaction Simulation for User Safety
Dapp teams simulate user transactions off-chain to prevent costly failures and improve user experience by previewing outcomes before execution.
Production-Grade Node Infrastructure and Monitoring
Enterprises deploy Tenderly’s scalable Node RPC for reliable, high-throughput access to multiple EVM chains, combined with real-time monitoring and alerting.
