CSV Payouts

About

This script reads a list of recipients and the corresonding amounts to be sent and executes each entry as a transaction on substrate based networks.

Config

See config/ for some examples.

Main

endpoint: wss://rpc.polkadot.io
actionFilePath: config/sample.actions.csv
keystore:
  walletFilePath: config/sample.key.json
  password: "p4ssw0rd"

Action / CSV File

The action file contains a list of <RECIPIENT>,<AMOUNT> pairs that dictate what transactions should be executed. For example;

1YgA2g4yVkKcDVktHrgEMT7n6YrU3tebH9Tu3hfpaiMCJJS,4
1PGsXH1HqkBMsQGcyHJscE9VxUnS9XSBHKFmkB8r4Vc7YFW,3.5
16VQH2rDYVGitsifyoNhwQyDQ5xFbR44i6vaQEayEqZ3nnn5,10

This script handles the conversion to the chains base units, e.g. if you specify 4 on Polkadot (implying 4 DOTs to be sent) that the script will convert it automatically to 4000000000 units.

Wallet File

The account that should be used to execute the transaction. It expects a json file exported from polkadot.js.org which is decrypted with the associated password.

Execution

• NOTE: The execution of this script should not be interrupted (for caching purposes). Instead, let it complete fully (which might result in an error).
• NOTE: Please do a test run first. The author(s) take(s) no liability (see license).

$ yarn
$ yarn start -c config.yaml

Caching

Execution creates a local .action_cache.json file which keeps track of which transactions have already been executed. Restarting the process will skip the already completed transactions and continue with the remaining entries of the CSV list until all have been successfully executed.
