Overview

pandoras-box is a small transaction stress testing tool, part of any Ethereum client developer's toolkit. It is made for Ethereum-compatible blockchain networks, such as Ethereum networks, Polygon Edge, HyperLedger and others.

The key features of pandoras-box are the following:

• ✅ Supports transaction batching, making stress testing orchestration hassle-free
• ✅ Supports multiple stress testing modes
• ✅ Supports distributed transaction stress testing through subaccounts
• ✅ Automatic subaccount fund top-off
• ✅ Has detailed statistics calculation
• ✅ Has support for outputting cycle-run results

Usage Example

Usage: pandoras-box [options]

A small and simple stress testing tool for Ethereum-compatible blockchain clients

Options:
  -V, --version                        output the version number
  -url, --json-rpc <json-rpc-address>  The URL of the JSON-RPC for the client
  -m, --mnemonic <mnemonic>            The mnemonic used to generate spam accounts
  -s, -sub-accounts <sub-accounts>     The number of sub-accounts that will send out transactions (default: "10")
  -t, --transactions <transactions>    The total number of transactions to be emitted (default: "2000")
  --mode <mode>                        The mode for the stress test. Possible modes: [EOA, ERC20, ERC721] (default: "EOA")
  -o, --output <output-path>           The output path for the results JSON
  -b, --batch <batch>                  The batch size of JSON-RPC transactions (default: "20")
  -h, --help                           display help for command

For any stress test run, there need to be funds on a specific address. The address that is in charge of funds distribution to subaccounts is the first address with index 0 in the specified mnemonic.

To initiate a 100 transaction EOA stress test run on an Ethereum-compatible blockchain network with a JSON-RPC endpoint at http://127.0.0.1:10002, with batch limits being 5000, and outputting the result to a file:

pandoras-box -url http://127.0.0.1:10002 -m "erupt oven loud noise rug proof sunset gas table era dizzy vault" -t 100 -b 5000 -o ./myOutput.json

Modes

EOA

The EOA mode is pretty straightforward - it is a simple value transfer mode between regular Ethereum accounts. This mode sends out transactions with a certain value transfer between subaccounts.

ERC20

The ERC20 mode deploys an ERC20 token to the blockchain network being tested before starting the cycle run. When the cycle run begins, the transactions that are sent out are ERC20 token transfers between subaccounts.

ERC721

The ERC721 mode deploys an ERC721 NFT contract to the blockchain network being tested before starting the cycle run. When the cycle run begins, the transactions that are sent out are ERC721 NFT mints.
