# Export Testnet

## Prerequisites

- Machine where the SAPO testnet validator node is already running

  - Install `zstd` using `sudo apt install zstd` (Linux) or `brew install zstd` (macOS)

  - [laconic-so](https://github.com/cerc-io/stack-orchestrator/?tab=readme-ov-file#install)

  - laconicd-stack

    ```bash
    laconic-so fetch-stack git.vdb.to/cerc-io/laconicd-stack --git-ssh --pull
    ```

## Export testnet state

- Run the following steps in machine where the testnet node is already running (machine 1)

- Export the testnet deployment directory as environment variable:

  ```bash
  export TESTNET_DEPLOYMENT_DIR=<absolute/path/to/testnet/deployment>
  ```

- Get your private key from testnet deployment (should be available if steps for joining SAPO testnet was followed previously):

  ```bash
  laconic-so deployment --dir $TESTNET_DEPLOYMENT_DIR exec laconicd "laconicd keys export <key-name> --unarmored-hex --unsafe --keyring-backend test"
  ```

  NOTE: Store this key securely as it is needed in later steps for signing bootstrap validator node gentx

- Stop the node for SAPO testnet:

  ```bash
  laconic-so deployment --dir $TESTNET_DEPLOYMENT_DIR stop
  ```

- Run script to export state from testnet chain:

  ```bash
  ~/cerc/laconicd-stack/scripts/export-testnet-state.sh $TESTNET_DEPLOYMENT_DIR
  ```

  - The compressed zst file will be generated at `$TESTNET_DEPLOYMENT_DIR/export/testnet-state.zst`

- The generated state file will be used in later steps for creating genesis.json file for mainnet

## Prepare LPS distribution JSON

- The following steps can be performed in any machine

- Fetch laconicd-stack
  
  ```bash
  laconic-so fetch-stack git.vdb.to/cerc-io/laconicd-stack --git-ssh --pull
  ```

- Set envs:

  ```bash
  # File path where LPS distribution JSON file will be created
  export LPS_DISTRIBUTION_PATH=<absolute/path/to/distribution.json>
  ```

- Generate lockup distribution JSON file with LPS distribution Google spreadsheet URL or downloaded CSV file path

  ```bash
  ~/cerc/laconicd-stack/scripts/generate-lps-lock.sh -i "<lps-distribution-spreadsheet-url-or-csv-file-path>" -o $LPS_DISTRIBUTION_PATH
  ```

- This will generate the JSON file at `$LPS_DISTRIBUTION_PATH` which will be later required when creating genesis file

## Requirements for Mainnet Genesis

- Exported testnet state
- LPS distribution JSON
- Account address for early supports
  - This account will be allocated 20% of total LPS tokens
- Private key of account which will sign gentx for the bootstrap validator node
