How to add new kind of wallet, such as TokenPocket

[johnson86tw]

This discussion comes from issue #82

My advice is to take a look at how metamask (or walletConnect) implements the connector interface

// src/connectors/connector.ts
export type ConnectorData<Provider = any> = {
  account: string
  provider: Provider
}

export abstract class Connector<
  Provider = providers.ExternalProvider | CoinbaseWalletProvider,
  Options = any,
> {
  // Connector name
  abstract readonly name: string
  // Options to pass to the third-party provider
  readonly options: Options

  constructor(options: Options) {
    this.options = options
  }

  abstract connect(): Promise<Required<ConnectorData>>
  abstract getProvider(): Promise<Provider>
  abstract disconnect(): Promise<void>
  abstract onDisconnect(handler: (...args: any[]) => any): void
  abstract onAccountsChanged(handler: (accounts: string[]) => any): void
  abstract onChainChanged(handler: (chainId: number) => any): void

  switchChain?(chainId: number): Promise<void>
}
