building at a server a description of the validated digital object;

providing to the second client device an access to the description to select the validated, described digital object for transfer; and

transferring the validated, described digital object to the second client device.

2. The method of claim 1, wherein the digital object comprises

a game object used in a game program.

3. The method of claim 2, further comprising

validating the game object for compliance with the game program using validation tools.

4. The method of claim 1, wherein said providing access to the description includes facilitating a search for the description.

5. The method of claim 1, further comprising

transacting an exchange for the validated, described digital object using an auction server which communicates with the server to auction and transfer the transacted digital object from the first client device to the second client device when the second client device obtains the digital object in auction.

6. The method of claim 5, wherein said transacting an exchange includes:

determining a payment in exchange for the validated, described digital object; and

facilitating a transfer of the payment.

7. The method of claim 1, wherein said transferring the validated, described digital object of the designed item type includes

transferring each of the multiple copies of the digital object separately to different buyers.

8. The method of claim 7, further comprising

disabling a copy of the digital object on the first client device upon said receiving the digital object.

9. The method of claim 7, further comprising

deleting a copy of the digital object from a memory of the first client device upon said transferring the validated, described digital object to the second client device.

10. The method of claim 1, further comprising

updating digital rights management information relating to the digital object.

11. The method of claim 1, wherein the digital object is a digital car object and the predefined rules ensure that no performance parameters for the digital car object are out of bounds.

12. A non-transitory computer-readable storage medium storing a computer program for use in transferring a digital object in an electronic game, the program comprising:

an editor to create a digital object designated as one of at least two types;

a designed item type and a developed item type,

wherein the designed item type is used to make multiple copies of the digital object,

wherein the developed item type is built by developing the digital object through a series of modifications during game play, and is unique because only one copy of the digital object is generated, and

wherein the type of digital object is interchangeable,

wherein the editor configured to generate an encryption key, the editor including an encryption module to encrypt the digital object using the encryption key, and to store the encrypted digital object locally on the non-transitory computer-readable storage medium;

a validation module to validate a digital object according to predefined rules,

wherein the validation module analyzes and tests data comprising the digital object to ensure conformance with the predefined rules and that no parameters are outside of predefined limits for performance of the digital object in the electronic game;

adjusting the digital object to conform with the predefined rules when the digital object does not conform with the predefined rules after said validating;

a description module to build a description of the validated digital object;

an access module providing access to the description of the digital object to select the validated, described digital object for transfer; and
