Correct Private Key Format

Developers

I’m working on getting a plugin built by PickPump on Eliza. I’m able to load the plugin. However, the token creation fails and returns this error: Failed to create token: Cannot read properties of null (reading 'createActor')

  1. Does anyone know what’s the right private key “format” to get a Wallet Provider instance?
  2. If anyone was able to run the ICP plugin on Eliza, let me know the steps you took to input the right private key in INTERNET_COMPUTER_PRIVATE_KEY.

Here are the steps that I am taking:

  1. I’m downloading a PEM file (let’s call it pkey.pem) from my Plug wallet and then running this in the command line:
    openssl pkey -in pkey.pem -text -noout

  2. The command line prints out something like this:

openssl pkey -in pkey2.pem -text -noout
ED25519 Private-Key:
priv:
    aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:
    aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:
    aa:aa
pub:
    ba:ba:ba:ba:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:
    aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:
    aa:aa
  1. I add the following to my .env file. I know that my .env file is loading properly because I have other API keys of services that are running properly:
INTERNET_COMPUTER_PRIVATE_KEY=aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:
    aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa
  1. However, I get an error Failed to create token: Cannot read properties of null (reading 'createActor').

The source code is here: https://github.com/elizaOS/eliza/blob/main/packages/plugin-icp/src/providers/wallet.ts.

From what I can infer, potentially, I am sending in a private key that is not being recognized and cannot instantiate a new provider instance.

I believe that this is the right way to get a ed25519 private key?

Generate a hex private key without the “0x” prefix using the following command:
openssl ec -in pkey2.pem -text -noout | grep priv -A 3 | tail -n +2 | tr -d ‘\n[:space:]:’ | xxd -r -p | xxd -p
Then set the output as your environment variable.
