The purpose of this script is to create a json file to refund users from a slash event.
Usage:
git clone https://github.com/LavenderFive/refund.git
cd tendermint_refund
python3 src/refund.py --denom {denom} --daemon {denom} --c {chain_id} -e {rpc_endpoint} -vc {valcons_address} -v {valoper_address} -s {send_address}
# example:
python3 src/refund.py --denom uatom --daemon gaiad --c cosmoshub-4 -e http://65.21.132.124:10657 -vc cosmosvalcons1c5e86exd7jsyhcfqdejltdsagjfrvv8xv22368 -v cosmosvaloper140l6y2gp3gxvay6qtn70re7z2s0gn57zfd832j -s cosmos15s9vggt9d0xumzqeq89scy4lku4k6qlzvvv2lz -m "With 💜 from Lavender.Five Nodes 🐝"
This will output two different kinds of files
/tmp/dist_<denom>_<batch #>.jsonwhich is the unsigned JSON representation of a batch transaction~/dist_<denom>_<batch #>_signed.jsonwhich represents the signed, but not yet broadcast batch transaaction
In addition to the original Lavender.Five nodes version of this script, there are two new command
line options, --dry_run and -f/--refund_file. Details below:
$ python3 src/refund.py --help
usage: refund.py [-h] --denom DENOM --daemon DAEMON -c CHAIN_ID -e ENDPOINT -vc VALCONS_ADDRESS -v VALOPER_ADDRESS -s SEND_ADDRESS [-m MEMO] -k KEYNAME [--dry_run [DRY_RUN]] [-f REFUND_FILE]
Create json file for refunding slashing to delegators
optional arguments:
-h, --help show this help message and exit
--denom DENOM denom for refunds (ex. uatom)
--daemon DAEMON daemon for refunds (ex. gaiad)
-c CHAIN_ID, --chain_id CHAIN_ID
Chain ID (ex. cosmoshub-4)
-e ENDPOINT, --endpoint ENDPOINT
RPC endpoint to node for gathering data
-vc VALCONS_ADDRESS, --valcons_address VALCONS_ADDRESS
Valcons address of validator (ex. cosmosvalcons1c5e86exd7jsyhcfqdejltdsagjfrvv8xv22368),
you can get this by doing {daemon} tendermint show-address
-v VALOPER_ADDRESS, --valoper_address VALOPER_ADDRESS
Valoper address of validator (ex. cosmosvaloper140l6y2gp3gxvay6qtn70re7z2s0gn57zfd832j),
you can get this by doing {daemon} keys show --bech=val -a {keyname}
-s SEND_ADDRESS, --send_address SEND_ADDRESS
Address to send funds from
-m MEMO, --memo MEMO Optional. Memo to send in each tx (ex. With 💜 from Lavender.Five Nodes 🐝)
-k KEYNAME, --keyname KEYNAME
Wallet to issue refunds from
-f REFUND_FILE, --refund_file REFUND_FILE
CSV file that encodes the delegator addresses and refund amounts. Note: delegator address is expected to be in the first column and the refund amount in [DENOM] is expected to be in the fourth column.
--dry_run Indicates whether this should actually broadcast transactions or not
--no_broadcast Similar to dry run, but in this case the tx JSON is output and signed, but not broadcast. This is useful for testing.
You may be tempted to believe the best way forward is to query against a node for addresses using block height, a la:
{daemon} q staking delegations-to {valoper_address} --height {block_height} --page {page} --output json --limit {page_limit} --node {endpoint} --chain-id {chain_id}
And with under 1500 delegators, you would be correct. Anything above that, and 10 load-balanced nodes was insufficient.
