Tezos support in Truffle is experimental. Give it a spin, and help us out by filing issues on Github.

Using the Truffle Console with Tezos

Sometimes it's nice to work with your contracts interactively for testing and debugging purposes, or for executing transactions by hand. Truffle provides you an easy way to do this via an interactive console, with your contracts available and ready to use.


To launch the console, run the following from your project folder:

truffle console

Truffle will immediately look for a network definition called development in the configuration, and connect to it, if available. You can override this using the --network <name> option or customize the development network settings. See more details in the Networks section as well as the command reference.

When you load the console, you'll immediately see the following prompt:


This tells you you're running within a Truffle console using the development network.


The Truffle console provides most of the features available in the Truffle command line tool. For instance, you can type migrate --reset within the console, and it will be interpreted the same as if you ran truffle migrate --reset on the command line from within your Truffle project.

Additionally, the console has the following features:

  • All of your compiled contracts are available and ready for use, via objects like SimpleStorage, which are given the same names as your contracts.
  • After each command (such as migrate --reset) your contracts are reprovisioned so you can start using the newly assigned addresses and binaries immediately.


Here's an example using the SimpleStorage contract that comes with the tezos-example Truffle box. In this example, we first run the deploy command, which deploys our contracts to the configured network (equivalent to running truffle deploy from the shell). We then use the supplied contract abstraction to get an object that represents the deployed SimpleStorage contract; call its main() function, creating a new transaction; and then get the contract's data after the transaction completed successfully.

truffle(development)> deploy


   Deploying 'SimpleStorage'
   > operation hash:      opNAUau1XwLzhLJud4XmabRppE81QkZaWm2EcUNeMsxjN2qnRDf
   > Blocks: 1            Seconds: 24

// truncated output

truffle(development)> let instance = await SimpleStorage.deployed()
truffle(development)> await instance.main(2)    // Make transaction against main() function
  tx: 'op8HbSFaHACRQrVZT7SmHjpRwqa9fDVxb6Zjwcyj57jwEgzKpcd',
} // transaction output
truffle(development)> await  // Get storage data
BigNumber { s: 1, e: 0, c: [ 2 ] }

For more information using the contract abstractions made available in the console, see the Interacting With Your Tezos Contracts section.

Commands available

You can run the following commands from within the console:

  • build
  • compile
  • create
  • debug
  • deploy
  • exec
  • help
  • install
  • migrate
  • networks
  • opcode
  • publish
  • run
  • test
  • version

If a Truffle command is not available, it is because it is not relevant for an existing project (for example, init) wouldn't make sense (for example, develop or console).

See full command reference for more information.
