How to airdrop tokens to many wallets on Solana

Plan the airdrop

Decide who gets tokens and how many. A holder snapshot is a common source.
Put the list in a CSV with one address and one amount per row.
Keep enough of the token and enough SOL for rent and fees in the sending wallet.

Why it costs more than it looks

Every recipient that has never held the token needs a token account. Creating it costs about 0.002 SOL of rent, paid by the sender.
A transaction has a size limit, so only some transfers fit in each one. A big list needs many transactions.
Tool fees come on top. Jumpbit's multisender charges 0.003 SOL per recipient, or about 0.0015 SOL with ZK compression.

ZK compression

Compressed tokens avoid creating a full token account per recipient, which cuts the cost. Recipients then claim or decompress the tokens into a normal token account when they want to use them.

Send it

Connect the sending wallet to a multisender.
Upload the CSV and check the total.
Send a small test batch to wallets you control.
Run the full list and keep the transaction links as your record.

Compare multisenders on the multisenders page.

Common mistakes

Duplicate or malformed addresses in the CSV.
Forgetting that decimals apply: an amount of 1 may mean 0.000001 of the token.
Sending from a wallet that also needs the tokens for liquidity.

Questions people ask

Who pays the rent for recipients' token accounts?

The sender, unless the recipient already has a token account for that token.

Can I get the rent back?

Only the account owner can close the account and reclaim it.

Is there a limit on recipients?

Each transaction fits only a limited number of transfers, so large lists are split into many transactions.
