What is Tenderly?

1 min read Updated

Tenderly is a blockchain development platform offering transaction simulation, debugging, monitoring, and alerting — enabling developers to test smart contract interactions before executing them on-chain.

WHY IT MATTERS

Tenderly is a developer's X-ray vision for blockchain. Before sending a transaction, simulate it to see exactly what will happen: which contracts will be called, what state will change, how much gas will be used, and whether it will succeed or revert.

Key features: transaction simulation (test before you send), Forks (private test environments), Web3 Actions (serverless automation), monitoring and alerting (watch for on-chain events), and gas profiling.

For agent developers, Tenderly's simulation API is particularly valuable — agents can simulate transactions before execution, catching errors and unexpected outcomes before they cost real money.

FREQUENTLY ASKED QUESTIONS

What is transaction simulation?
Running a transaction against current blockchain state without actually sending it. You see the full execution trace, state changes, and outcome — then decide whether to proceed.
What are Tenderly Forks?
Private copies of blockchain state that you can modify and test against. Like a sandbox mainnet — same state and contracts, but your changes don't affect the real network.
Is Tenderly free?
Free tier with limited simulations and features. Paid plans from $50/month for teams. The free tier is sufficient for individual development; teams typically need paid features.
