# Mango Simulation - test solana cluster by simulating mango markets

This project is use to stress a solana cluster like devnet, testnet or local solana cluster by simulating mango markets. This code requires ids.json which describe mango group for a cluster and accounts.json file which has preconfigured user accounts in mango.

To create a new configuration for mango for your cluster please check the following project:
<https://github.com/godmodegalactus/configure_mango>

The code then will create transaction request (q) requests per seconds for (n) seconds per perp market perp user. Each transaction request will contains remove following instruction CancelAllPerpOrders and two PlacePerpOrder (one for bid and another for ask).

For the best results to avoid limits by quic it is better to fill the argument "identity" of a valid staked validator for the cluster you are testing with.

## Build

Clone repo
```sh

```

Build
```sh
cargo build
```

## Run

```sh
cargo run --bin mango-simulation -- -u http://localhost:8899 --identity validator-identity.json --keeper-authority authority.json --accounts accounts.json  --mango ids.json --mango-cluster localnet --duration 10 -q 2 --transaction_save_file tlog.csv --block_data_save_file blog.csv
```

Details for each argument:
```
USAGE:
    mango-simulation [OPTIONS] --accounts <FILENAME> --mango <FILENAME>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -a, --accounts <FILENAME>                 Read account keys from JSON file generated with mango-client-v3
        --batch-size <UINT>                   If specified, transactions are send in batches of specified size
    -b, --block-data-save-file <FILENAME>     To save details of all block containing mm transactions
    -C, --config <FILEPATH>                   Configuration file to use [default:
                                              /home/galactus/.config/solana/cli/config.yml]
    -d, --duration <SECS>                     Seconds to run benchmark, then exit; default is forever
    -n, --entrypoint <HOST:PORT>              Rendezvous with the cluster at this entry point; defaults to
                                              127.0.0.1:8001
    -i, --identity <FILEPATH>                 Identity used in the QUIC connection. Identity with a lot of stake has a
                                              better chance to send transaction to the leader
    -u, --url <URL_OR_MONIKER>                URL for Solana's JSON RPC or moniker (or their first letter): [mainnet-
                                              beta, testnet, devnet, localhost]
    -k, --keeper-authority <FILEPATH>         If specified, authority keypair would be used to pay for keeper
                                              transactions
    -c, --mango-cluster <STR>                 Name of mango cluster from ids.json
    -m, --mango <FILENAME>                    Read mango keys from JSON file generated with mango-client-v3
        --markets-per-mm <UINT>               Number of markets a market maker will trade on at a time
        --prioritization-fees <UINT>          Takes percentage of transaction we want to add random prioritization fees
                                              to, prioritization fees are random number between 100-1000
    -q, --quotes-per-second <QPS>             Number of quotes per second
    -t, --transaction-save-file <FILENAME>    To save details of all transactions during a run
        --ws <URL>                            WebSocket URL for the solana cluster
