Run an instant-send (MultiSender) airdrop on Saleium
Updated Jun 21, 2026, 09:46 AM
An instant-send (MultiSender) airdrop pushes a token or the native coin to many wallets right now, in auto-batched transactions, with no platform fee. You pay only network gas.
Who this is for: Operators who want to distribute tokens directly to a list of recipients in one campaign.
What is an instant-send (MultiSender) airdrop?
Instant send is one of the two airdrop modes on Saleium. It pushes tokens to everyone immediately instead of asking recipients to claim. The other mode, the Claim page (Merkle), deploys a claim contract that recipients claim from themselves. Use instant send when you want to deliver the tokens yourself and cover the network cost. The native coin (the chain's gas coin) is instant-only and cannot use claim mode.
Airdrops are available on every plan, including Free (1 campaign, up to 100 recipients). Your plan sets the maximum recipients per campaign. If you exceed that limit, the wizard prompts you to upgrade.
How do I set up my recipient list?
You have four ways to provide recipients:
- Paste a list of "address, amount", one per line.
- Toggle "Send the same amount to everyone" and give a single amount, then paste only the addresses.
- Upload a CSV (up to 5 MB).
- Choose "Import current holders" of an ERC-20, which snapshots the holders into the address list. You then set the amount each holder receives.
Duplicate addresses are merged automatically. Before you send, a preview shows the recipient count, the total amount, and how many batches the send will take.
How do I run an ERC-20 instant send, step by step?
- Open the Airdrop tool and choose instant send (MultiSender).
- Add your recipients using any of the four input methods above.
- Review the preview: recipient count, total tokens, and batch count.
- Approve the total amount of the ERC-20. This lets the contract move the full amount you are distributing.
- Confirm the send. Large recipient lists are auto-batched into multiple transactions. The in-app preview shows the batch count for your specific send, and that count is the source of truth.
- Pay the network fee for each batch. You pay a small network fee per recipient. There is no platform fee.
For the native coin, there is no approval step, since the native coin is sent directly. Everything else works the same way.
What does it cost?
There is no platform fee for airdrops. You pay only network gas. With instant send you pay a small network fee per recipient, charged as the batches are submitted to the chain. Make sure the sending wallet holds enough of the native coin to cover gas for every batch.
Common issues
A batched send failed partway through. If a batched instant send fails midway, the batches that already went out were paid and delivered. Before you retry, remove the recipients who were already sent from your list. If you resend the full list, you will pay those recipients a second time.
My campaign is larger than my plan allows. Your plan caps the recipients per campaign. The wizard prompts an upgrade when you exceed it. You can also split a very large drop across modes: for large drops, the Claim page (Merkle) mode is often the better fit because recipients claim and pay their own gas.
I want recipients to use the native coin in claim mode. That is not supported. Claim mode is ERC-20 only. The native coin can only be sent through instant send.
Duplicate addresses in my list. Duplicates are merged automatically, so the same wallet is not sent twice within a single campaign. Check the preview total to confirm the merged result matches what you intended.
