greeter is a simple demo of Arbitrum's L1-to-L2 message passing system (aka "retryable tickets").
It deploys 2 contracts - one to L1, and another to L2, and has the L1 contract send a message to the L2 contract to be executed automatically.
The script and contracts demonstrate how to interact with Arbitrum's core bridge contracts to create these retryable messages, how to calculate and forward appropriate fees from L1 to L2, and how to use Arbitrum's L1-to-L2 message address aliasing.
See ./exec.js for inline explanation.

Set the values shown in .env-sample as environmental variables. To copy it into a .env file:
cp .env-sample .env(you'll still need to edit some variables, i.e., DEVNET_PRIVKEY)
