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.
Requirements:
- Go
- make
- jq
- bc
- protoc (Only required for
make generate)
To install, clone this repo and run:
make installBy 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 by cobra using make gen-doc.

To test the features of polycli, we'll run geth in dev mode but you can run any node you want.
make gethYou can then fund the default load testing account and run some tests.
make geth-loadtestYou can view the state of the chain using polycli.
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.txtYou 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.

geth attach /var/folders/7m/3_x4ns7557x52hb6vncqkx8h0000gn/T/geth.ipcFrom there, you can do anything such as funding the default load testing account with some currency.

"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 is 1337.

You can install stringer with go install golang.org/x/tools/cmd/stringer@latest.
