We are among the first Sui Devnet JSON-RPC providers. Now we are excited to expand our API Service to WebSocket too. WebSocket would be useful to those dApps that need to take action on real-time on-chain events.

How to get started?​

Step 1. Go to https://blockeden.xyz/dash/. Please sign up if you haven’t done so.

Step 2. Input your name for the API key, select Sui Devnet Websocket, and then click + Create key.

Step 3. Grab your access URL by clicking Copy to copy it to the clipboard.

Step 4. Use the access URL in your project like the following. Remember to replace <access_key> with your own key.

How to use WebSocket?​

To quickly play around WebSocket endpoint in the command line, you could use wscat. To download it, run the following command:

npm install -g wscat

Then, run the following command to connect to the WebSocket endpoint (remember replacing with your own API key):

wscat -c wss://sui-devnet.blockeden.xyz/kjz2sTknHkNE9aXQ6j1N

Now in the session, you could give the command. For example, you could say subscribing events that matchin some cerntain criteria:

Connected (press CTRL+C to quit)
> {"jsonrpc":"2.0", "id": 1, "method": "sui_subscribeEvent", "params": [{"All":[{"EventType":"MoveEvent"}, {"Package":"0x2"}, {"Module":"devnet_nft"}]}]}
< {"jsonrpc":"2.0","result":6240320950310564,"id":1}

And you would also observe events being streamed to your console:

< {"jsonrpc":"2.0","method":"sui_subscribeEvent","params":{"subscription":6240320950310564,"result":{"timestamp":1672211297607,"txDigest":"PDPBHEo5pmMeLK8Dc4226MZxUA2dkQK91W2ECHFgN1a","id":{"txSeq":1471806,"eventSeq":2},"event":{"moveEvent":{"packageId":"0x0000000000000000000000000000000000000002","transactionModule":"devnet_nft","sender":"0x35a09652085b5c4c178d9cfe234d8c1a6b89306b","type":"0x2::devnet_nft::MintNFTEvent","fields":{"creator":"0x35a09652085b5c4c178d9cfe234d8c1a6b89306b","name":"Example NFT","object_id":"0x7631724b6eb066b8514c6159f716a8826055ee5e"},"bcs":"djFyS26wZrhRTGFZ9xaogmBV7l41oJZSCFtcTBeNnP4jTYwaa4kwawtFeGFtcGxlIE5GVA=="}}}}}

...

For more details of subscribing Sui events via WebSocket, please refer to the offical doc.

Misc​

To prevent too many outstanding idle connections, we will drop any WebSocket connection that hasn't exchanged data in the past 5 minutes. Client will receive an error code: 1006.
