Good day, @Nick-1979!

My name is Ashley and I work as a Technical Grants Evaluator at W3F. Thank you for your milestone 1 delivery!

I have installed the Plus plugin on Chrome and successfully connected my account! I can see the proper balance; I was also able to run & pass your unit tests, thank you!

I am confused on how to add the "Westend genesis & info" & rebuild from source. I am relatively new to the Polkadot ecosystem, so please forgive me. I cannot find these files in your codebase:

@polkadot/networks/genesis.js
@substrate/ss58-registry/index.js

Am I supposed to find these files in your codebase? Where are these files located?

Once I know, then I can add the westend genesis & info. Thank you!

Hi Ashley,

Some Polkadot packages do not  support Westend hence some tweaks are needed to add Westend to the supported chains .

The files to add westend are located in "node_modules' folder, which can be found in the root of the project (after that yarn has installed modules).

1. add the following Westend genesis to "./node_modules/@polkadot/networks/genesis.js"

westend:['0xe143f23803ac50e8f6f8e62695d1ce9e4e1d68aa36c1cd2cfd15340213f3423e']

2a. add the following Westend network information to "./node_modules/@substrate/ss58-registry/index.js" 

{ "prefix": 42, "network": "westend", "displayName": "Westend", "symbols": [ "WND" ], "decimals": [ 12 ], "standardAccount": "*25519", "website": "https://polkadot.network" })

2b. In case that you can not find "@substrate" folder in node modules (because it is added in the latest update of @PolkaDot package) you can add the following to  "./node_modules/@polkadot/networks/ substrate.js" instead as mentioned in the project readme file (https://github.com/Nick-1979/polkadot-Js-Plus-extension#to-test-on-westend).

{ decimals: [12], displayName: 'Westend', network: 'westend', prefix: 42, standardAccount: '*25519', symbols: ['WND'], website: 'https://polkadot.network' }

Finally a yarn build is needed to apply the changes.

The most convenient way to try the Westend is the compiled extension which is already available on Firefox addons page (https://addons.mozilla.org/en-US/firefox/addon/polkadot-js-plus-extension/).

If there are any other questions/issues I would be happy to answer/help.

Thank you, 

Kami
