chainId

• get chainId(): number

  Gets the current chain ID from the wallet client.

  Returns number

  The numeric chain ID of the connected network

  Example

  const chainId = vana.chainId;
  console.log(`Connected to chain: ${chainId}`); // e.g., "Connected to chain: 14800"
  Copy

chainName

• get chainName(): string

  Gets the current chain name from the wallet client.

  Returns string

  The human-readable name of the connected network

  Example

  const chainName = vana.chainName;
  console.log(`Connected to: ${chainName}`); // e.g., "Connected to: Moksha Testnet"
  Copy

validateStorageRequired

• validateStorageRequired(): void

  Validates that storage is available for storage-dependent operations. This method enforces the fail-fast principle by checking storage availability at method call time rather than during expensive operations.

  Returns void

  Throws

  When storage is required but not configured

  Example

  // This will throw if storage is not configured
  vana.validateStorageRequired();
  await vana.data.uploadFile(file); // Safe to proceed
  Copy

hasStorage

• hasStorage(): boolean

  Checks whether storage is configured without throwing an error.

  Returns boolean

  True if storage is properly configured

  Example

  if (vana.hasStorage()) {
    await vana.data.uploadFile(file);
  } else {
    console.warn('Storage not configured - using pre-stored URLs only');
  }
  Copy

isStorageEnabled

• isStorageEnabled(): this is VanaCore & StorageRequiredMarker

  Type guard to check if this instance has storage enabled at compile time. Use this when you need TypeScript to understand that storage is available.

  Returns this is VanaCore & StorageRequiredMarker

  True if storage is configured, with type narrowing

  Example

  if (vana.isStorageEnabled()) {
    // TypeScript knows storage is available here
    await vana.data.uploadFile(file);
  }
  Copy

getUserAddress

• getUserAddress(): Promise<`0x${string}`>

  Retrieves the user's wallet address from the connected client.

  Returns Promise<`0x${string}`>

  A Promise that resolves to the user's Ethereum address

  Example

  const address = await vana.getUserAddress();
  console.log(`User address: ${address}`); // e.g., "User address: 0x742d35..."
  Copy

getConfig

• getConfig(): RuntimeConfig

  Retrieves comprehensive runtime configuration information.

  Returns RuntimeConfig

  The current runtime configuration including chain, storage, and relayer settings

  Example

  const config = vana.getConfig();
  console.log(`Chain: ${config.chainName} (${config.chainId})`);
  console.log(`Storage providers: ${config.storageProviders.join(", ")}`);
  Copy

setPlatformAdapter

• setPlatformAdapter(adapter: VanaPlatformAdapter): void

  Sets the platform adapter for environment-specific operations. This is useful for testing and advanced use cases where you need to override the default platform detection.

  Parameters

  • adapter: VanaPlatformAdapter

    The platform adapter to use

  Returns void

  Example

  // For testing with a mock adapter
  const mockAdapter = new MockPlatformAdapter();
  vana.setPlatformAdapter(mockAdapter);
  
  // For advanced use cases with custom adapters
  const customAdapter = new CustomPlatformAdapter();
  vana.setPlatformAdapter(customAdapter);
  Copy

getPlatformAdapter

• getPlatformAdapter(): VanaPlatformAdapter

  Gets the current platform adapter. This is useful for advanced use cases where you need to access the platform adapter directly.

  Returns VanaPlatformAdapter

  The current platform adapter

  Example

  const adapter = vana.getPlatformAdapter();
  const encrypted = await adapter.encrypt(data, key);
  Copy

encryptBlob

• encryptBlob(data: string | Blob, key: string): Promise<Blob>

  Encrypts data using the Vana protocol standard encryption. This method automatically uses the correct platform adapter for the current environment.

  Parameters

  • data: string | Blob

    The data to encrypt (string or Blob)
  • key: string

    The key to use as encryption key

  Returns Promise<Blob>

  The encrypted data as Blob

  Example

  const encryptionKey = await generateEncryptionKey(walletClient);
  const encrypted = await vana.encryptBlob("sensitive data", encryptionKey);
  Copy

decryptBlob

• decryptBlob(
      encryptedData: string | Blob,
      walletSignature: string,
  ): Promise<Blob>

  Decrypts data that was encrypted using the Vana protocol. This method automatically uses the correct platform adapter for the current environment.

  Parameters

  • encryptedData: string | Blob

    The encrypted data (string or Blob)
  • walletSignature: string

    The wallet signature to use as decryption key

  Returns Promise<Blob>

  The decrypted data as Blob

  Example

  const encryptionKey = await generateEncryptionKey(walletClient);
  const decrypted = await vana.decryptBlob(encryptedData, encryptionKey);
  const text = await decrypted.text();
  Copy
