[Feature] Support Stacks Blockchain

[friedger]

Is your feature request related to a problem? Please describe.
As a Stx holder, I would like to send and receive stx. Ideally, I would be able to stack/stake my stx.

Describe the solution you'd like
The app should show the stx balance and let me receive and send stx.

Support for sip9 tokens would be the next step.

Describe alternatives you've considered
Use a different app 😭

Additional context
I can help developing, but need some guidance about the process.

You can refer to it first.

If there's anything you don't understand, or that method doesn't understand, I'll help you out.

@ByteZhang1024 What is the different between IEncodedTx and IDecodedTx? They are both structured objects.

[ByteZhang1024]

IEncodedTx
It is generally defined in terms of different chains, usually transaction formats. It is primarily an object of direct flow within our internal business. e.g Everyone is familiar with ETH.

export type IEncodedTxEvm = {
  from: string;
  to: string;
  value: string;
  data?: string;
  customData?: string;
  nonce?: number | string;

  gas?: string;
  gasLimit?: string;
  gasPrice?: string;
  maxFeePerGas?: string;
  maxPriorityFeePerGas?: string;
};

IDecodedTx
Is a format we define for trading decode, which is used for various ui presentations. Transactions from any other chain can be converted into i decoded tx to display information on different business pages.
It can be converted from IEncodedTx
e.g https://github.com/OneKeyHQ/app-monorepo/blob/onekey/packages/engine/src/vaults/impl/evm/Vault.ts#L238

@ByteZhang1024 Thank you for the clarification.

How do you handle testnets? I see that create createClientFromURL does not take a testnet or chainid flag.

Looking at the format here, just add a test chain.
