Tenderly CLI

GitHub tag (latest SemVer)

Tenderly CLI is a suite of development tools that allows you to debug, monitor and track the execution of your smart contracts.

Table of Contents

The login command is used to authenticate the Tenderly CLI with your Tenderly Dashboard.

tenderly login

Command Flags

Flag Default Description
--authentication-method / Pick the authentication method. Possible values are email or token
--email / The email used when authentication method is email
--password / The password used when authentication method is email
--token / The token used when authentication method is token
--force false Don't check if you are already logged in
--help / Help for login command


The init command is used to connect your local project directory with a project in the Tenderly Dashboard.

tenderly init

Command Flags

Flag Default Description
--project / The project name used for generating the configuration file
--create-project false Creates the project provided by the --project flag if it doesn't exist
--re-init false Force initializes the project if it was already initialized
--help / Help for init command


The push command is used to add your contracts to the Tenderly Dashboard.

tenderly push

Command Flags

Flag Default Description
--networks / A comma separated list of network ids to push
--tag / Optional tag used for filtering and referencing pushed contracts
--help / Help for push command

Advanced usage

It is possible to push to multiple projects by editing the tenderly.yaml file and providing a map of projects and their networks. To do this remove the already provided project_slug property and replace it with the projects property like the example below;

projects: # running tenderly push will push the smart contracts to all of the provided projects
    - "1" # mainnet
    - "42" # kovan
    # if the networks property is not provided or is empty the project will be pushed to all of the migrated networks
    # if you want to push to a shared project provide the full project identifier
    # the identifier can be found in you Tenderly dashboard under the projects name


The verify command uploads your smart contracts and verifies them on Tenderly.

tenderly verify

Command Flags

Flag Default Description
--networks / A comma separated list of network ids to verify
--help / Help for verify command

Proxy Debugging

The proxy server is currently made to work with the Truffle framework and requires the proxy to be run from the root of your Smart Contract project where the Truffle configuration is located.

// Example using Ganache defaults
tenderly proxy --target-port 7545

In your Truffle configuration, configure your local network config to point to the running proxy or create a new network for proxy debugging.

module.exports = {
    networks: {
        proxy: {
            host: "",
            port: 9545,
            network_id: "*",
            gasPrice: 0
        ganache: {
            host: "",
            port: 7545,
            network_id: "*",
            gasPrice: 0

After setting up the network you can now call your Truffle commands just as before by changing the --network to the appropriate one.

$user > truffle exec ./scripts/test-scripts.js --network proxy
Using network 'proxy'.

Error: 0x0 Error: REVERT, execution stopped
	at require(square == original)
		in FailContract:5


Now when your transactions fail you can see the exact line of code in which the error occurred and the whole stacktrace by using our proxy command.


You must run truffle migrate --network proxy first, so the contract information (address to source mapping) can be picked up by the proxy command from the build folder.

Command Flags

Flag Default Description
--path "./" Path to the project build folder where your Truffle configuration is located
--proxy-host "" Host on which the proxy will be listening
--proxy-port "9545" Port on which the proxy will be listening
--target-host "" Target host of your Blockchain RPC
--target-port "8545" Target port of your Blockchain RPC
--target-schema "http" Blockchain RPC protocol
--write-config / Write proxy settings to the project configuration file
--help / Help for proxy command

Check for updates

The update-check command checks if there is a new version of the Tenderly CLI and gives update instructions and changelog information.


The version command prints out the current version of the Tenderly CLI.

tenderly version

Who am I?

The whomai command prints out basic information about the currently logged in account

tenderly whoami


The logout command disconnects your local Tenderly CLI from your Tenderly Dashboard

tenderly logout
