Add EVM wallet support to polygon prototype

[prayagd]

Context

As the user would start from Polygon chain, the prototype need to support EVM wallet

Requirement

• Add EVM wallet support
• User should be able to connect EVM wallet
• can enquire the users's balance of a particular ERC-20 token (with a hard coded address)
• submit arbitrary signed user transactions

Note

• List of EVM wallet libraries to choose from
• https://portal.thirdweb.com/typescript/v5/supported-wallets
• https://docs.walletconnect.com/appkit/overview
• https://web3auth.io/docs/sdk/pnp/web/

@pendulum-chain/devs High priority ticket, so your quick estimation would be highly appreciated

[prayagd]

Hey team! Please add your planning poker estimate with Zenhub @b-yap @bogdanS98 @ebma @gianfra-t @TorstenStueber

All their details should be fetched for the prototype i.e Account address and Token balances

Not sure whether we request this from the wallet. It could just be that we request this directly from the RPC node but it depends on the library.

The main goal of this ticket is that we:

• can enquire the users's balance of a particular ERC-20 token (with a hard coded address)
• submit arbitrary signed user transactions

(Depending on the wallet library) this might require that we also connect to some EVM RPC node.

Update the ticket based on your comment

@ebma what sdk are we going ahead with out of the above? Klaus would need this for design refernce

[ebma]

We will probably use rainbowkit. You can see the example dialogs on their website.

@ebma should we close this ticket?

Yes, let's do that. EVM wallet support was merged to polygon-prototype-staging in this PR.
