# What is Tenderly?

> Tenderly is the simulation company for onchain operations, helping risk, engineering, and finance teams model every move before capital is exposed.

Tenderly is the simulation-powered platform for running blockchain systems across 100+ networks. Engineering, finance, and risk teams use it to model every transaction, financial strategy, deployment, and integration against the real, live state of their systems before capital is exposed, and to operate with full context in production.

With Tenderly as a single operational layer, teams can:

* **Simulate:** preview the exact outcome of any transaction, multi-step workflow, or cross-chain deployment against live network state, before anything is committed.
* **Understand:** inspect every transaction, contract, and asset movement with the most granular execution data onchain, decoded into human-readable context.
* **Respond:** monitor every condition that matters across your systems and act fast to mitigate critical incidents.

## How Tenderly enables onchain flows

Tenderly is a blockchain operations platform powered by a simulation engine and deep transaction tracing and decoding capabilities. It consists of several products covering the entire operational flow.

### Simulator: model every action before it's final

See the exact outcome of a transaction, a multi-step workflow, or an entire cross-chain deployment against real network state, with full control over every parameter.
