Implement RPC calls in Jupyter/Colab #124

Closed DanielSchiavini closed 7 months ago

DanielSchiavini commented 7 months ago

Fixes #119 Depends on https://github.com/vyperlang/titanoboa/pull/132

What I did

Extended the interface with the browser to support RPC calls.

How I did it

It includes two new classes on the python side:

BrowserRpc calls the browser when a RPC call is made
boa.set_browser() combines BrowserRpc and BrowserSigner together to allow the environment to be used in boa
boa.set_network(url) works as an alternative to boa.set_env(NetworkEnv(url))

The JavaScript uses this method from ethers.js.

Tests are included, but unfortunately I had to mock all jupyter and tornado dependencies - they aren't installed in boa normally.

How to verify it

Install this branch and then run in Jupyter or Google Colab:

import boa
boa.set_browser()

boa.env.eoa should return your wallet address.
boa.env.get_gas_price() returns the current gas price.
Deploying and calling contracts should still work

Description for the changelog

Add new boa.set_browser() interface to interact with the browser wallet RPC in JupyterLab
