SIP Protocol API Reference / BaseWalletAdapter

Abstract Class: BaseWalletAdapter

Defined in: @sip-protocol/sdk/dist/index-DXh2IGkz.d.ts:12522

Abstract base class for wallet adapters

Provides:

• Event emitter infrastructure
• Connection state management
• Common validation logic

Subclasses must implement:

• connect() / disconnect()
• signMessage() / signTransaction() / signAndSendTransaction()
• getBalance() / getTokenBalance()

Example

class MyWalletAdapter extends BaseWalletAdapter {
  readonly chain = 'solana'
  readonly name = 'my-wallet'

  async connect(): Promise<void> {
    // Implementation
  }

  // ... other required methods
}

Extended by

• EthereumWalletAdapter
• LedgerWalletAdapter
• MockEthereumAdapter
• MockLedgerAdapter
• MockSolanaAdapter
• MockTrezorAdapter
• MockWalletAdapter
• SolanaWalletAdapter
• TrezorWalletAdapter

Implements

• IWalletAdapter
