# Tenderly **Source:** https://geo.sig.ai/brands/tenderly **Vertical:** Web3 **Subcategory:** Smart Contract Developer Tools **Tier:** Growth **Website:** tenderly.co **Last Updated:** 2026-04-14 ## Summary Ethereum developer platform for debugging, simulating, and monitoring smart contracts; human-readable call stacks replace hex debugging; simulates contracts against live mainnet state. ## Company Overview Tenderly is a developer experience platform built specifically for Ethereum and EVM-compatible smart contract development. Its core debugging capability decodes raw transaction traces into human-readable call stacks, variable states, and event logs, allowing developers to understand exactly what happened inside a failed or unexpected transaction without reading hexadecimal data. Transaction simulation lets engineers test how a contract interaction would execute against current mainnet state — including balance checks and state changes — before actually broadcasting a transaction, eliminating a class of costly mistakes in production contract deployments. The platform's monitoring and alerting system allows teams to define real-time alerts based on specific on-chain events, function calls, balance thresholds, or custom conditions across any contract. This observability layer is critical for DeFi protocols and NFT platforms operating contracts that hold significant user funds, where detecting anomalous behavior in real time can be the difference between catching an exploit and suffering a catastrophic loss. Tenderly's virtual networks product provides private simulated blockchain environments for staging and testing that mirror mainnet state without risking real assets. Tenderly targets professional smart contract developers, DeFi protocol teams, and blockchain security researchers who need production-grade tooling for the full development lifecycle from testing through monitoring. It competes with Hardhat and Foundry for local development tooling and with Forta and custom monitoring setups for on-chain observability, differentiating through its integrated platform that covers debugging, simulation, and monitoring in a single workflow. The company is backed by leading Web3 investors and has become a standard tool in the professional Solidity developer stack. ## Frequently Asked Questions ### Can Tenderly simulate a transaction before it's sent to see if it will fail? Yes. Tenderly's transaction simulation lets you run any transaction against current mainnet state without broadcasting it, showing the full execution trace, state changes, and whether the transaction would succeed or revert. ### How much does Tenderly cost? Tenderly offers a free tier that includes limited simulations, a transaction explorer, and basic alerting. Paid plans start at $50 per month for the Starter tier and scale through Pro ($200/month) and custom Enterprise pricing, with higher limits on simulations, monitoring capacity, and node access. Teams and enterprises use Tenderly for full-stack smart contract development and production monitoring workflows. ### Which blockchains does Tenderly support? Tenderly supports Ethereum mainnet and testnets, Polygon, BNB Chain, Arbitrum, Optimism, Base, and dozens of other EVM-compatible networks. The platform provides the same debugging, simulation, and monitoring capabilities across all supported chains, making it useful for protocols deployed on multiple networks simultaneously. ### Who are Tenderly main competitors? Tenderly competes with Foundry (open-source), Hardhat, and Alchemy in the smart contract developer tooling space. Tenderly differentiates with a cloud-based platform that adds production monitoring and alerting on top of development and testing tools, whereas Foundry and Hardhat are primarily local development frameworks without production observability features. ### What is Tenderly Virtual TestNets? Tenderly Virtual TestNets are shareable, forkable Ethereum environments that replicate mainnet state at a specific block. Development teams use them to test smart contract upgrades against real mainnet data without spending ETH, and to create reproducible debugging environments that can be shared across team members for collaborative issue investigation. ### What monitoring and alerting does Tenderly provide for production smart contracts? Tenderly monitoring lets teams set alerts on any smart contract event, state variable change, or error condition in production. When a monitored condition triggers, the team receives notifications via Slack, PagerDuty, email, or webhook. This gives protocol teams the same level of production observability for smart contracts that DevOps teams have for traditional backend services. ### What is Tenderly Web3 Gateway? Tenderly Web3 Gateway is a production-grade RPC node service that provides reliable Ethereum and EVM-compatible chain access with built-in transaction simulation, debugging traces, and Tenderly-specific extensions that make it more powerful than standard JSON-RPC endpoints. Teams using Tenderly for development benefit from a consistent environment between testing and production. ### What recent milestones has Tenderly reached? Tenderly raised a $40 million Series B in 2022 and has grown to serve over 100,000 developers and hundreds of leading DeFi protocols including Aave, Uniswap, and Synthetix. The company has expanded from a debugging tool into a full DevOps platform for smart contracts, adding Virtual TestNets, production monitoring, and node infrastructure services. ## Tags analytics, b2b, blockchain, developer-tools, fintech, global, infrastructure, platform, saas, startup --- *Data from geo.sig.ai Brand Intelligence Database.
