Transferring an Application

How to Transfer an Application​

See pocketd tx application transfer --help:

Usage:
    pocketd tx application transfer [source app address] [destination app address] [flags]

How it Works​

Application Transfer Sequence​

Application Module State Access​

Why is There an Transfer Period?​

  1. Simplify account settlement complexities
  2. Weak subjectivity: adversarial behaviour + unstake + run away

Gotchas & Troubleshooting​

Unstaking - Can I unstake an application which is pending transfer?​

Applications which are pending transfer cannot be unstaked.

warning

Attempting to unstake an application which is pending transfer, will result in an error.

Transferred to Wrong Destination - Can I recover from this?​

If you've mistakenly transferred an application the wrong destination, so long as you have authority over the destination, recovery is possible:

  1. Note the destination application's current configuration

    pocketd query application show-application <app_address>

    Example output:

    application:
      address: pokt1ad28jdap2zfanjd7hpkh984yveney6k9a42man
      delegatee_gateway_addresses: []
      pending_transfer: null
      pending_undelegations: {}
      service_configs:
        - service_id: anvil
        - service_id: rest
        - service_id: ollama
          stake:
          amount: "1000068"
          denom: upokt
          unstake_session_end_height: "0"

  2. Unstake the destination application

    pocketd tx application unstake <app_address> --from <key_name>

    The application's unstake_session_end_height will be set to the current session end height and can be queried with the same command:

    pocketd query application show-application <app_address>

    # OR More specifically, using `jq` or `yq`
    pocketd query application show-application <app_address> | yq .application.unstake_session_end_height
    pocketd query application show-application <app_address> -o json | jq .application.unstake_session_end_height

  3. Wait for the application unbonding period to elapse

    The application unbonding period is a governance parameter which in terms of sessions after the end height of the session in which the application was unstaked. Its value can be queried with:

    pocketd query shared params

    # OR More specifically, using `jq` or `yq`
    pocketd query shared params | yq .params.application_unbonding_period_sessions
    pocketd query shared params -o json | jq .params.application_unbonding_period_sessions

    The current height can be queried with:

    pocketd query block

    # OR More specifically, using `jq` or `yq`
    pocketd query block | yq .header.height
    pocketd query block -o json | tail -n -1 | jq .header.height

  4. Re-stake the destination application with its original or expected configuration and stake

    pocketd tx application stake <app_address> --config <wrong_destination_restore_config_path> --from <key_name>

  5. Stake the correct/intended destination application with the transferred sources configuration and stake

    pocketd tx application stake <app_address> --config <intended_destination_config_path> --from <key_name>
