Repository files navigation

We run a lot of different blockchain technologies. Different tools often have inconsistent tooling and this makes automation and operations painful. The goal of this codebase is to standardize some of our commonly needed tools and provide interfaces and formats.

• Install
• Features
• Testing
• References

Requirements:

• Go
• make
• jq
• bc
• protoc (Only required formake generate)

To install, clone this repo and run:

make install

By default, the commands will be in$HOME/go/bin/, so for ease, we recommend adding that path to your shell's startup file by adding the following line:

export PATH="$HOME/go/bin:$PATH"

Note: Do not modify this section! It is auto-generated bycobra usingmake gen-doc.

To test the features ofpolycli, we'll run geth indev mode but you can run any node you want.

make geth

You can then fund the default load testing account and run some tests.

make geth-loadtest

You can view the state of the chain usingpolycli.

polycli monitor --rpc-url http://127.0.0.1:8545

Note that if you want to debug the monitor, you can use the following command.

polycli monitor --rpc-url http://34.117.145.249:80 -v 700&> log.txt

You can also interact manually with your node, you can attach a Javascript console to your node using IPC.

First, wait for the IPC endpoint to open.

INFO [07-10|10:44:29.250] Starting peer-to-peer node               instance=Geth/v1.12.0-stable/darwin-amd64/go1.20.4WARN [07-10|10:44:29.250] P2P server will be useless, neither dialing nor listeningINFO [07-10|10:44:29.255] Stored checkpoint snapshot to disk       number=0 hash=039839..dcb5c1DEBUG[07-10|10:44:29.255] IPCs registered                          namespaces=admin,debug,web3,eth,txpool,clique,miner,net,engineINFO [07-10|10:44:29.256] IPC endpoint opened                      url=/var/folders/7m/3_x4ns7557x52hb6vncqkx8h0000gn/T/geth.ipcINFO [07-10|10:44:29.256] Generated ephemeral JWT secret           secret=0x7511b4e6312a1a63348d8fc8c6a586ed4ea69ed31c27b3c0cc5e41cb6d2d5822

Then, attach a console to your node.

geth attach /var/folders/7m/3_x4ns7557x52hb6vncqkx8h0000gn/T/geth.ipc

From there, you can do anything such as funding the default load testing account with some currency.

> eth.coinbase==eth.accounts[0]true> eth.sendTransaction({from: eth.coinbase, to:"0x85da99c8a7c2c95964c8efd687e95e632fc533d6", value: web3.toWei(5000,"ether")})"0xd8223589989d198741e0543ab01d9d3ce2b81e38927cb213a56589e111dfd388"

You can then generate some load to make sure that blocks with transactions are being created. Note that the chain id of local geth is1337.

polycli loadtest --verbosity 700 --chain-id 1337 --concurrency 1 --requests 1000 --rate-limit 5 --mode c --rpc-url http://127.0.0.1:8545

If you add a new loadtest mode, don't forget to update the loadtest mode string by running the following command:cd cmd/loadtest && stringer -type=loadTestMode. You can installstringer withgo install golang.org/x/tools/cmd/stringer@v0.37.0.
