Mass Send Statemine assets on Kusama

Usage

This will send out the existential deposit and a selected amount of a Statemine asset to a list of addresses included in a file.

The file must include ONLY addresses, one per line.

Note: You will need to enter your seed phrase for the account at the command line. This is, of course, very insecure. I recommend using a pass-through account which only stores the amount of assets and KSM to be sent out.

Command line arguments

1. asset_id - The Statemine asset ID you wish to send
2. amount_in_placks - The amount in Plancks you will send to each account. Note that different Statemine assets have different levels of precision!
3. filename - The filename to read, which should contain a list of Kusama addresses, one per line
4. seed_phrase_in_quotes - The seed phrase of the account from which a keypair will be generated and KSM/assets sent. Of course this account must already have some KSM and the asset you wish to send!
5. -P - Optional flag to determine whether to use Polkadot (Statemint) or Kusama (Statemine), omit for Kusama.

Example

This example sends 100 Billcoins (asset ID 223) to the addresses found in filename.txt. This is of course a dummy seed phrase; you will need to make your own Statemine account and fund it with KSM and the asset you wish to send.

python3 send.py 223 10000000000 filename.txt "end cry link reason crunch shine enroll supreme boost cluster fame devote"

Usage on Statemint

This is meant for STATEMINE, not STATEMINT, assets.

To use on Statemint, change the STATEMINE_EXISTENTIAL_DEPOSIT and STATEMINE_NODE constants to the right Statemint values.

Ideally, this would support Statemine/Statemint selection from the command line. PRs accepted.

Helpful Hint

Use cat file.txt | grep -o "[CDEFGHIJKLMN][a-zA-Z0-9]\{45\}[a-zA-Z0-9]*" | uniq to get a list of all Kusama addresses in file.txt

Note that there is a bug where this regex will occasionally pick up Substrate (5...) addresses, but missing the 5 prefix. These will be ignored by send.py, though, since they are not valid Kusama addresses (even though they look like them!)
