Implementation Reference

• src/handlers/wallet.ts:642-664 (handler)

  The core handler function that executes the tool logic: retrieves the ENS resolver for the given name using the provider's getResolver method.

  export const getEnsResolverHandler = async (input: any): Promise<ToolResultSchema> => {
    try {
      if (!input.name) {
        return createErrorResponse("ENS name is required");
      }
  
      const provider = getProvider();
      if (!provider) {
        return createErrorResponse("Provider is required to get ENS resolver, please set the provider URL");
      }
      // In ethers.js v5, getResolver might not be directly on the provider type
      // but it's available in the implementation
      const resolver = await (provider as any).getResolver(input.name);
  
      return createSuccessResponse(
      resolver ? `ENS resolver retrieved successfully
        Address: ${resolver.address}
        Name: ${resolver.name}
      ` : "No resolver found for this ENS name");
    } catch (error) {
      return createErrorResponse(`Failed to get ENS resolver: ${(error as Error).message}`);
    }
  };
