Generate a Session Key

Generate the key

Make the request from your VM (where your collator node container is running) using the following command:

curl -X 'POST' \
-H "Content-Type: application/json" \
-d '{"id":1, "jsonrpc":"2.0", "method": "author_rotateKeys", "params":[]}' http://localhost:9944

Copy the key from the response:


In this case, the key is:


Associate your session key with your collator account

Open the Developer tab, and click Extrinsics, there you'll need to submit the following extrinsic

Developer -> Extrinsics -> session -> setKeys(keys, proof)


You can use any krest endpoint to submit setKeys sxtrinsic, including the endpoint from your VM with collator node.


  1. Paste your session key into the aura: SpConsensusAuraSr25519AppSr25519Public field
  2. Paste 0x00 into the field proof: Bytes
  3. Click Submit Transaction

After using setKeys extrinsic, you can connect back to the public endpoint.

Double-check that your session key is associated with your wallet address

Open the Developer tab, and click Chain state. There, you'll need to submit the following state query:

  1. DeveloperChain stateSessionnextKeys

Session Keys

  1. Toggle the switch include option and select your collator address in the AccountId32 field.
  2. Click the + button.
  3. Confirm that your key is displayed.

Remove unsafe rpc methods from your node

Remove --unsafe-rpc-external and --rpc-methods=unsafe methods, which we needed in the beginning, and rerun the container.
