​
Wallet Preloading

​
preloadWallet()

Preloads the wallet service to improve performance by initializing the wallet infrastructure before it’s needed. Method Signature: 
public async preloadWallet(): Promise<void>
Usage: 
try {
  await airService.preloadWallet();
  console.log("Wallet preloaded successfully");
} catch (error) {
  console.error("Failed to preload wallet:", error);
}
Important notes:
  • The wallet can be preloaded even before the user is logged in
  • Improves response time for subsequent wallet operations
  • Even if preloading hasn’t finished, using the provider or any other wallet operation will ensure that the wallet is done initializing before executing the actual call
Requirements:
  • Service must be initialized

​
EIP-1193 Wallet Provider

​
getProvider()

Returns an EIP-1193 compatible provider that works seamlessly with popular Web3 libraries such as web3, ethers, and Viem. Method Signature: 
getProvider(): EIP1193Provider
Returns: An EIP-1193 compatible provider object with the following interface: 
interface EIP1193Provider {
  request(request: AirProviderParameters): Promise<unknown>;
  on<EventName extends keyof EIP1193EventMap>(
    event: EventName,
    listener: EIP1193EventMap[EventName]
  ): void;
  removeListener<EventName extends keyof EIP1193EventMap>(
    event: EventName,
    listener: EIP1193EventMap[EventName]
  ): void;
}
Supported Events: 
type EIP1193EventMap = {
  accountsChanged(accounts: string[]): void;
  chainChanged(chainId: string): void;
  connect(connectInfo: ProviderConnectInfo): void;
  disconnect(error: ProviderRpcError): void;
  message(message: ProviderMessage): void;
};
Requirements:
  • User must be logged in

​
Standard RPC Methods

The provider also supports all standard EIP-1193 methods: 
// Get accounts
const accounts = await provider.request({ method: "eth_accounts" });

// Request accounts
const accounts = await provider.request({ method: "eth_requestAccounts" });

// Get chain ID
const chainId = await provider.request({ method: "eth_chainId" });

// Send transaction
const txHash = await provider.request({
  method: "eth_sendTransaction",
  params: [transactionParams]
});

// Sign message
const signature = await provider.request({
  method: "personal_sign",
  params: [message, address]
});

// Switch chain
await provider.request({
  method: "wallet_switchEthereumChain",
  params: [{ chainId: "0x2105" }] // Base mainnet
});

// And more standard RPC calls

​
Wallet Events

The EIP-1193 provider supports standard wallet events: 
const provider = airService.getProvider();

// Listen for account changes
provider.on("accountsChanged", (accounts) => {
  console.log("Accounts changed:", accounts);
});

// Listen for chain changes
provider.on("chainChanged", (chainId) => {
  console.log("Chain changed to:", chainId);
});

// Listen for connection events
provider.on("connect", (connectInfo) => {
  console.log("Wallet connected:", connectInfo);
});

// Listen for disconnects
provider.on("disconnect", (error) => {
  console.log("Wallet disconnected:", error);
});
