Quick start guide

Welcome to Evolve, a chain framework! The easiest way to launch your network node is by using the Testapp CLI.

📦 Install Testapp (CLI)

To install Evolve, run the following command in your terminal:

curl -sSL https://evolve.dev/install.sh | sh -s v1.0.0-beta.2

Verify the installation by checking the Evolve version:

testapp version

A successful installation will display the version number and its associated git commit hash.

evolve version:  execution/evm/v1.0.0-beta.1
evolve git sha:  cd1970de

🗂️ Initialize a evolve network node

To initialize a evolve network node, execute the following command:

testapp init --evolve.node.aggregator --evolve.signer.passphrase secret

🚀 Run your evolve network node

Now that we have our testapp generated and installed, we can launch our chain along with the local DA by running the following command:

First lets start the local DA network:

curl -sSL https://evolve.dev/install-local-da.sh | bash -s {{constants.evolveLatestTag}}

You should see logs like:

4:58PM INF NewLocalDA: initialized LocalDA module=local-da
4:58PM INF Listening on host=localhost maxBlobSize=1974272 module=da port=7980
4:58PM INF server started listening on=localhost:7980 module=da

To start a basic evolve network node, execute:

testapp start --evolve.signer.passphrase secret

Upon execution, the CLI will output log entries that provide insights into the node's initialization and operation:

🎉 Conclusion

That's it! Your evolve network node is now up and running. It's incredibly simple to start a blockchain (which is essentially what a chain is) these days using Evolve. Explore further and discover how you can build useful applications on Evolve. Good luck!
