Unlimited multisend · ERC-20 · NFTs
Send to thousands of wallets in a single operation.
Native coin, ERC-20 tokens and NFTs (ERC-721 and ERC-1155) to as many addresses as you like. Upload a CSV, add them by hand or generate new wallets. The system splits the transfer into batches and shows the real price in € and $ before you sign.

// 01 · How it works
Four steps, one progress window
Pick network and asset
Ethereum, Polygon, Base, Arbitrum, Optimism, BNB, Avalanche or a testnet. Native coin, token or NFT.
Add recipients
CSV with address and amount, one by one, or the generator: create N new wallets and send to all of them.
See the real price
Calculated with current gas: one-by-one cost, batch cost, your saving and the fee.
Sign and wait
You sign each batch in your wallet. A window shows what the system is working on until it finishes.
// 02 · Pricing
We charge half of what you save
No subscriptions. The fee is included in each batch and broken down before you sign.
Mainnets
50 % of the saving
We compare what you would pay sending one by one with the batch cost. You keep half of the saving; no saving, no fee.
Generated wallets
+1 euro cent / wallet
If you use the generator, 1 euro cent is added per wallet created. Keys are created in your browser.
Testnets
50 % of one transfer
On Sepolia or Amoy you pay, per address, half the cost of a single transfer on that network, in its test coin (worth €0).
Example with 1,000 addresses (gas measured on real transactions)
| Case | Gas one by one | Gas in batches | Gas saving | You save |
|---|---|---|---|---|
| ERC-20 token to wallets that never held it | 51.6 M | 27.1 M | 47 % | 24 % |
| ERC-20 token to wallets that already hold it | 34.5 M | 10 M | 71 % | 35 % |
| ERC-721 NFT | 55.1 M | 35 M | 36 % | 18 % |
| ERC-1155 NFT | 57.1 M | 32.2 M | 44 % | 22 % |
| Native coin to used wallets | 21 M | 10.7 M | 49 % | 24 % |
| Native coin to brand-new wallets | 21 M | 35.6 M | — | no fee |
Sending native coin to a never-used wallet costs more gas from a contract than in a plain transaction (an Ethereum rule): there is no saving there and we charge no fee. “You save” already subtracts our fee.
// 03 · What's included
Built for big transfers
No address limit
Upload 50 or 500,000. The system picks the best batch size for the chosen network.
CSV, paste or manual
Validates every line, flags duplicates and lets you fix things before paying.
Wallet generator
Choose how many wallets and the amount. They are created in your browser and you download the keys as CSV.
ERC-721 and ERC-1155 NFTs
Distribute a whole collection or copies of one NFT with a single approval.
Progress and resume
See every batch: signature, confirmation and record. If you close, resume from “My transfers”.
Verified contract
Signed, single-use price per batch. Fees go to a fixed treasury. We never ask for your seed phrase.
// 04 · Questions
Frequently asked questions
Is there really no address limit?
No. Each network caps gas per transaction, so the system splits your list into batches (e.g. 400–1,000 addresses each) and sends them one after another. You sign each batch in your wallet.
How is the fee calculated?
On mainnets: we compute the gas of sending one by one and in batches, at the current gas price. The fee is 50 % of the difference. On testnets: 50 % of the cost of a single transfer per address.
Why do I see €0 on Sepolia?
Test coins have no value, so the € and $ equivalent is 0. The fee is still paid, in SepoliaETH or Amoy POL.
What about the keys of generated wallets?
They are generated in your browser and never sent to our server. Download them as CSV or copy them. If you don't save them, nobody can recover what is sent to those wallets.
What if the window closes halfway?
Confirmed batches stay done. Open “My transfers” in the same browser and press “Resume”: it continues where it stopped.
Which approvals do I give?
For tokens, one approve for the total you send. For NFTs, a collection approval (setApprovalForAll) you can revoke afterwards from your wallet. For native coin, none.
Can I send different amounts to each address?
Yes. In the CSV and the manual entry every line has its own amount. In the generator, all receive the same.
Why can the price change when signing?
Gas changes every few seconds. When you press “Send” the price is fixed and signed for one hour. If more time passes, the system re-prices only what's pending.
