This directory contains typescript script describing the different topics presented by the frontier node template.
Use npm i to install dependencies. To create an ERC20 contract,
execute node_modules/.bin/ts-node create-erc20.ts while your
template node is running in --dev mode.
The ouput of the command should look similar to this:
└────╼ ts-node create-erc20.ts
Initiating the API (ignore message "Unable to resolve type B..." and "Unknown types found...")
Unable to resolve type B, it will fail on construction
Unknown types found, no types for B, Receipt, Transaction
