Airdrop

A CLI airdrop tool that

• Always send to receiver's associated token address
• Processes token transfers concurrently
• Ensures that each unique transfer request is processed only once
• Confirms transfer transactions
• Tolerates program restarts and RPC errors

Airdrop Input File

This airdrop tool will read transfer requests from an input file, where each line is a JSON object:

• memo: a string that distinguishes between different airdrop campaigns
• amount: the amount of tokens to send
• to: the main wallet address of receiver
• mint: to tokene to send

{"memo":"abcd","amount":"1000000","to":"C23a3jPhw84hy6mRAhBbNhjgzSuGFcGeNExCCBe1bHSM","mint":"4ZqfC84c1qgMnLgjeoi5tPfpmvHhinvhQSYjfYGLjaDT"}

These fields are appended together to form a unique key to make sure that each transfer request is processed exactly once.

Running Airdrop

Configure your wallet and RPC in .env:

# private key in hex.
# 6ewXcXuD1LWVr5qZWgzs3vjEQfY6EJQocWA3p46zqRth
WALLET=8cff95874f5212047774c0d1437c1f0d2c04ca400a3b2f706edee7b179392fd0540294506b9309e39f1a6ddd928903d32d3ecdac7ed355da139837ea1f821b86

# solana RPC node
RPC=https://api.devnet.solana.com

airdrop -c 5 airdrop.100.json

• airdrop.100.json is the input file of airdrop requests
• -c 5 specifies a concurrency of 5 when processing requests

(Note: the public RPC has stringent rate-limit, so use a lower concurrency.)

The progress of the airdrop would be saved in airdrop.store.json:

{
  "abcd:C23a3jPhw84hy6mRAhBbNhjgzSuGFcGeNExCCBe1bHSM:4ZqfC84c1qgMnLgjeoi5tPfpmvHhinvhQSYjfYGLjaDT:1000000": {
    "TXID": "4CR8CKoXRmnGTKews84X4x3uJZNTHZoykPHsaHvCjrm7xxhNdCzJfc4jUSn9sCTzPi3h7MMrZPvJCKywxrRy2Czb",
    "Memo": "abcd",
    "Mint": "4ZqfC84c1qgMnLgjeoi5tPfpmvHhinvhQSYjfYGLjaDT",
    "To": "C23a3jPhw84hy6mRAhBbNhjgzSuGFcGeNExCCBe1bHSM",
    "Amount": "1000000",
    "ConnfirmedSlot": "78421840"
  },
  "abcd:C23a3jPhw84hy6mRAhBbNhjgzSuGFcGeNExCCBe1bHSM:4ZqfC84c1qgMnLgjeoi5tPfpmvHhinvhQSYjfYGLjaDT:2000000": {
    "TXID": "3Z1YohqR1TU4NMDaJmSaE6F2L8tBrNebLaxV2xsdfZRqQPAUUS9W2xAvnv77awMcaBZusDJ8DLf6NdgMKzepV5k8",
    "Memo": "abcd",
    "Mint": "4ZqfC84c1qgMnLgjeoi5tPfpmvHhinvhQSYjfYGLjaDT",
    "To": "C23a3jPhw84hy6mRAhBbNhjgzSuGFcGeNExCCBe1bHSM",
    "Amount": "2000000",
    "ConnfirmedSlot": "78421877"
  }
}

The airdrop.store.json file ensures that the airdrop are processed exactly once, and verify that the transactions have gone through.

If the airdrop program is interrupted half-way through, you can restart it again, and the program will load history from airdrop.store.json to pick up from where it left off.

Running Airdrop (Advanced)

The parrot needs to process many airdrops simultaneously when distributing +earn profits to users. The airdrop tool can process multiple input files:

airdrop -c 20 \
  airdrop-MERLP-USDC.USDT.UST+earn.json \
  airdrop-SBRLP-USDT.USDC+earn.json \
  airdrop-SBRLP-USD.UST+earn.json \
  airdrop-SBRLP-SOL.mSOL+earn.json
