Designed to read in a file for processing

now supports a token id of 'hbar' to send hbar via airdrop

instructions for running towards the bottom

file format (headers):

serial is only needed when the token being sent is an NFT and can be ommited when snding FUNGIBLE_COMMON tokens

serial=0 implies send a random NFT owned (excluding any serials in the .env file EXCLUDE_SERIALS variable [a comma seperated list or a range NEVER BOTH])

for example 0.0.XXXX,0.0.YYYYY,1,0 -> send any random NFT owned 0.0.XXXX,0.0.YYYYY,1,3 -> send user serial 3 (if owned else error message / skip) 0.0.XXXX,0.0.ZZZZZ,1 -> send user 1 FC token 0.0.XXXX,hbar,2.25,0 -> send user 2.25 hbar

ASSUMPTIONS The sending account is treasury account (or there are no royalties - specifically a fall back fee) so there is no need for the receiving party to sign.

If sending Fungible Common tokens that all instructions for a given token will be grouped together for efficiency. Will still work if seperated but may end up with more transactions than optimal thus slower.

Script will:

• read in the file
• check the quantity to send is not more than MAX_TRANSFER tokens [quantity will be adjusted down (floor 0) if possible] -- check across lines (dupes)
• check the token type [NFT/FC/HBAR]
• check the destination address has the token associated
• upon validation of the line store the pending transaction
• continue until input file processed
• check sender has enough tokens to honour the request
• spit out human form the of the transaction to process (then exit is in -test mode)
• batch the transactions to process [dealing with NFT and FC tokens seperately]

setup your.env file [sending wallet / PK / any limit on sending / memo ]

node tokenAirdrop.js -process -> send out the airdrop

node tokenAirdrop.js -process -test -> run the process without sending any tokens.

in more narrative format

you will need a .env file - can create or rename .env.example - i recommend the following settings (replacing your account/key of course

ENVIRONMENT=MAIN MY_ACCOUNT_ID=0.0.222 MY_PRIVATE_KEY=302asbbdskbfjhfskhkds MAX_TRANSFER= MEMO='Airdrop' EXCLUDE_WALLETS= EXCLUDE_SERIALS=

then create a file to drive the airdrop - call it whatever you like (you do not need the header but included for easier reference):

0.0.1111,0.0.1042640,5,***** 0.0.11111,0.0.1042695,5,***** 0.0.111111,0.0.1042726,1,0 0.0.111,hbar,2.2,0

replace *'s with a comma separated list of serials e.g. 1,3,6,10,15 (enough to match the quantity) or a 0 and it will pick them randomly.

then you can run from terminal:

node tokenAirdrop.js -process -test

filename being the name of the above instruction file you saved
