Once you have created some game assets with Metaplex and have integrated them in your Servers and Clients with your engine’s SDK, now it’s time to make sure the on chain state is accurately reflected in your game. You can do that with sync tooling.

RPCs

For a production ready service that can read the accurate state of the network, your team should work with an RPC provider. Learn more about RPC providers.

Each RPC will have its own special flavor, so be sure to research them.

Access patterns

• Pull - Clients have certain triggers that will trigger the RPC call
• Live update - Typically done through webhooks or websocket connection that streams data from the network
• Push - Server has some logic that will trigger based on chain or client activity that will update itself and all clients attached to that server.

Considerations

To inform the needs of your specification, it’s important to ask:

• When is it critical to have an accurate read of the on chain data?
  • MMO sandboxes, match based games, marketplaces, etc. will all have different requirements.

Security of a signing service

If your game design requires the server to mint of game items live — say on a boss kill or match reward — it’s important to keep security in mind. See details of the concerns and potential solutions here.

Examples

• Mint SPL tokens from a live server
