What you get

Tenderly is the blockchain operations platform teams use to run onchain systems in production. Model every transaction, deployment, and strategy against live network state before it’s final, investigate anything that happens onchain with fully decoded context, and respond to issues the moment they appear. The full platform is built for teams operating production systems, with a free account available so anyone can explore and debug any supported chain. This page covers what you get at each level, starting with the full platform.

​

The full Tenderly platform

Engineering, finance, and risk teams get a single operational layer across 100+ EVM networks, organized around four products.

​

Simulator: the simulation engine for every onchain decision

Simulator is Tenderly’s core capability, enabling you to preview the exact result of any onchain action against the live state of every chain you operate on, before any capital or users are exposed.

• Virtual Environments: production-mirroring environments with real oracle prices, current liquidity, and live protocol state. Spin them up in seconds, sync state continuously, and share one environment across your whole team instead of isolated local forks.
• Multichain environments with bridging: validate complete cross-chain workflows in a single environment, with built-in support for LayerZero, Chainlink CCIP, and Across.
• Full control over network state: impersonate any account, fund any address with any token through the unlimited faucet, override storage, advance time, and mine blocks with Admin RPC cheatcodes.
• Simulation API: dry-run any transaction programmatically and read back state diffs, asset changes, emitted events, gas usage, and a full execution trace.
• Simulation Bundles: sequence approvals, transfers, and protocol calls as a single multi-step unit, each step building on the state of the previous one, to validate entire user intents end-to-end.
• Simulator UI and Simulation Mode: build, edit, and re-run simulations in the dashboard, with state overrides, source edits, and historical or pending block context.
• CI/CD and staging: provision fresh environments per commit, pull request, or pipeline stage with GitHub Actions, Foundry, and Hardhat integrations.

​

Console: complete context for onchain activity

Console decodes the most granular execution data on the blockchain into human-readable context, for verified and unverified contracts alike, serving as the operational center for your team. The full platform adds multi-network coverage, shared team context, and the following products:

• Explorer: unified multi-network search, transaction listings, and decoded transaction views across every chain in your project.
• Debugger: step through any transaction to the exact line of code where it failed, evaluate expressions, edit contract source, and re-simulate to validate a fix.
• Gas Profiler: visual gas breakdown per function call, with access list recommendations.
• Fund Flow: follow capital movement through any transaction across addresses and protocols, with decoded context at every step.
• DeFi Modules: observe the health and activity of the lending protocols your product depends on, with positions, liquidity movement, and protocol risk in one view.
• Address management: import and label the wallets and contracts that matter to your organization so every team works with the same named entities.
• Private contract verification: verify contracts within your project only, keeping pre-release code and strategies off public networks.
• Team workspace: organizations and projects with role-based permissions, so engineering, support, and risk teams share one source of truth.

​

Monitor: the full detection-to-response pipeline

Catch early signals of unexpected behavior and move from detection to a verified response before issues cascade.

• Alerts: real-time rules for failed transactions, function calls, emitted events, balance and state changes, and threshold violations.
• Alert destinations: route notifications to Slack, Discord, Telegram, PagerDuty, email, or custom webhooks.
• Web3 Actions: execute custom code when conditions are met, from notifying the right team to pausing execution or triggering downstream workflows.

​

Node RPC: production-grade RPC infrastructure access

Scale with growing onchain usage on a highly scalable Node RPC with multi-regional traffic routing, low latency, and near-zero error rates.

• Node RPC: low-latency JSON-RPC across 80+ networks with full archive data.
• Simulations and gas estimation over RPC: embed transaction previews and accurate gas estimates directly into your product through the same connection that submits transactions.

​

Built for organizations

For teams with specific operational, security, or compliance requirements, Tenderly supports SSO sign-in, role-specific access control, private and custom chain support, and dedicated deployments within your own infrastructure.

​

What you get with a free account

A free account gives you access to:

• Explorer: search and inspect transactions, addresses, and assets with decoded context.
• Single-transaction simulation: run a transaction in the browser and see exactly what would happen before you sign anything.
• Impersonate any account: send simulated transactions as any public address. No private keys needed.
• Override balances and storage: pretend your wallet has 1,000 ETH, or that a contract slot holds a different value, and watch the outcome.
• Public contract verification: verify your contract source through the Dashboard or the Hardhat and Foundry plugins so the decoded view shows up for everyone.

​

What you get without an account

The core explorer and debugger surface is public. Drop any transaction hash, contract, or wallet address into Tenderly and inspect it on the network of your choice:

• Transaction details at a glance: token transfers, emitted events, balance and state changes, every contract involved.
• Full error and stack trace with human-readable revert messages, jump-to-revert, opcode search, and event logs, storage, and gas per call.
• Debugger: step through execution one opcode at a time, evaluate expressions, and inspect contract variables.
• Gas Profiler: visual breakdown of gas usage per function call.
• Account abstraction (ERC-4337) decoding: full UserOp visibility with bundler and paymaster context.
• Fund Flow: visual token-transfer graph across every call in a transaction.
• Read/write interfaces: interact with any verified contract directly from the UI.
