Conduit Arbitrum Tutorial

Bridging ETH

Bridge to your arbitrum l3 deployed with Conduit. To run, first

git clone git@github.com:conduitxyz/arbitrum-tutorial.git

Then in the cloned directory

yarn install

You will need a private key, your conduit rpc URL, and your inbox contract address.

Make sure your wallet has at least 0.4 eth to bridge over (you can change this by using the environment variable VALUE)

Your inbox contract address is available under core.json in your arbitrum orbit deployment console. Example json:
