$ go run main.go loadtest uniswapv3 --help
The `uniswapv3` command is a subcommand of the `loadtest` tool. It is meant to generate UniswapV3-like load against JSON-RPC endpoints.

You can either chose to deploy the full UniswapV3 contract suite.

polycli loadtest uniswapv3 http://localhost:8545

Or to use pre-deployed contracts to speed up the process.

Global Flags:
      --adaptive-backoff-factor float              When using adaptive rate limiting, this flag controls our multiplicative decrease value. (default 2)
      --adaptive-cycle-duration-seconds uint       When using adaptive rate limiting, this flag controls how often we check the queue size and adjust the rates (default 10)
      --adaptive-rate-limit                        Enable AIMD-style congestion control to automatically adjust request rate
      --adaptive-rate-limit-increment uint         When using adaptive rate limiting, this flag controls the size of the additive increases. (default 50)
      --batch-size uint                            Number of batches to perform at a time for receipt fetching. Default is 999 requests at a time. (default 999)
      --call-only                                  When using this mode, rather than sending a transaction, we'll just call. This mode is incompatible with adaptive rate limiting, summarization, and a few other features.
      --call-only-latest                           When using call only mode with recall, should we execute on the latest block or on the original block
      --chain-id uint                              The chain id for the transactions.
  -c, --concurrency int                            Number of requests to perform concurrently. Default is one request at a time. (default 1)
      --config string                              config file (default is $HOME/.polygon-cli.yaml)
      --contract-call-block-interval uint          During deployment, this flag controls if we should check every block, every other block, or every nth block to determine that the contract has been deployed (default 1)
      --contract-call-nb-blocks-to-wait-for uint   The number of blocks to wait for before giving up on a contract deployment (default 30)
      --gas-limit uint                             In environments where the gas limit can't be computed on the fly, we can specify it manually. This can also be used to avoid eth_estimateGas
      --gas-price uint                             In environments where the gas price can't be determined automatically, we can specify it manually
  -i, --iterations uint                            If we're making contract calls, this controls how many times the contract will execute the instruction in a loop. If we are making ERC721 Mints, this indicates the minting batch size (default 1)
      --legacy                                     Send a legacy transaction instead of an EIP1559 transaction.
      --output-mode string                         Format mode for summary output (json | text) (default "text")
      --pretty-logs                                Should logs be in pretty format or JSON (default true)

      --private-key string                         The hex encoded private key that we'll use to send transactions (default "42b6e34dc21598a807dc19d7784c71b2a7a01f6480dc6f58258f78e539f1a1fa")
      --rate-limit float                           An overall limit to the number of requests per second. Give a number less than zero to remove this limit all together (default 4)
  -n, --requests int                               Number of requests to perform for the benchmarking session. The default is to just perform a single request which usually leads to non-representative benchmarking results. (default 1)
      --seed int                                   A seed for generating random values and addresses (default 123456)
      --send-amount string                         The amount of wei that we'll send every transaction (default "0x38D7EA4C68000")
      --steady-state-tx-pool-size uint             When using adaptive rate limiting, this value sets the target queue size. If the queue is smaller than this value, we'll speed up. If the queue is smaller than this value, we'll back off. (default 1000)
      --summarize                                  Should we produce an execution summary after the load test has finished. If you're running a large load test, this can take a long time
  -t, --time-limit int                             Maximum number of seconds to spend for benchmarking. Use this to benchmark within a fixed total amount of time. Per default there is no time limit. (default -1)
      --to-address string                          The address that we're going to send to (default "0xDEADBEEFDEADBEEFDEADBEEFDEADBEEFDEADBEEF")
      --to-random                                  When doing a transfer test, should we send to random addresses rather than DEADBEEFx5
  -v, --verbosity int                              0 - Silent
                                                   100 Fatal
