- * Gets the private key for the current Vitest worker.
- *
- * The PK is basically the current worker's ID. This allows us to
- * have a unique faucet wallet for each file being tested and prevents
- * tests from trying to access to the same coins and fail.
- *
- * Both `faucets.json` and `initial_state.coins` in `chainConfig.json`
- * were manually generated to support at most 16 workers.
- *
- * For each wallet in `faucets.json`, there are three coins for each
- * of the following Asset IDs:
- *   - 0x0000000000000000000000000000000000000000000000000000000000000000
