Transaction Simulation

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.
