# Tenderly

> Tenderly is a full-stack Web3 infrastructure platform for building, testing, debugging, monitoring, and operating smart contracts on Ethereum and 100+ EVM-compatible blockchains. It provides developer tools including Virtual TestNets, transaction simulation, smart contract debugging, real-time alerting, Web3 Actions (serverless backend), and a high-performance multichain Node RPC.

Tenderly is used by all major DeFi protocols and Web3 teams, including Uniswap, MakerDAO, Aave, Safe, Chainlink, 1inch, Yearn, DeFi Saver, and InstaDapp. It supports networks including Ethereum, Arbitrum, Optimism, Base, Polygon, Linea, Avalanche, BNB Chain, Mantle, Gnosis, ZKsync, Monad, MegaETH and many more.

Founded in 2018 in Belgrade, Serbia, with offices in San Francisco. Funded by Spark Capital, Accel, Point Nine Capital, Coinbase Ventures, and others.

## Core Products

- [Node RPC](https://docs.tenderly.co/node): High-performance multichain node-as-a-service with custom RPC methods, Node Extensions, simulation RPC, and trace RPC
- [Transaction Simulator](https://docs.tenderly.co/simulations/single-simulations): Simulate single or bundled transactions before sending onchain — includes asset change previews, gas estimation, and state overrides
- [Debugger](https://docs.tenderly.co/debugger): Step-by-step smart contract debugging with full execution traces, state changes, and event emissions
- [Gas Profiler](https://docs.tenderly.co/debugger/gas-profiler): Granular gas usage analysis and optimization for smart contracts
- [Developer Explorer](https://docs.tenderly.co/developer-explorer/transaction-listing): Decoded onchain transaction insights — filter, sort, and inspect transactions with full contract and wallet management
- [Alerting](https://docs.tenderly.co/alerts/intro-to-alerts): Real-time monitoring with onchain triggers, webhooks, and destinations (PagerDuty, Telegram, Slack, email)
- [Web3 Actions](https://docs.tenderly.co/web3-actions/intro-to-web3-actions): Serverless JavaScript backend for responding to onchain events with built-in key-value storage and secrets management
- [Simulator UI](https://docs.tenderly.co/simulator-ui): Browser-based contract debugging and simulation
- [Contract Verification](https://docs.tenderly.co/contract-verification): Private or public smart contract verification using Foundry and Hardhat
