How to airdrop tokens on Robinhood Chain.

Published 2026-07-31 · HoodLock Team

Most airdrops are sent the expensive way: a script that pushes tokens into every wallet on a list, one transfer at a time. On Robinhood Chain (chain id 4663) you can do it in one transaction instead, for no platform fee, using HoodLock and a verified contract with no admin path to your tokens.

The one thing to understand first. Nothing is pushed to anybody. You fund the airdrop once and each recipient comes and claims their own share. That is what makes it cost the same for 10 wallets as for 100,000, and it is why your tokens never land in a wallet that never asked for them.

What it costs

Sending 100,000 transfers yourself means 100,000 transactions. An ERC-20 transfer to a wallet that has never held that token costs about 52,000 gas, because it writes a fresh storage slot, and an airdrop is by definition going to wallets like that.

Approach	Transactions	Your cost at 100,000 wallets
Script, one transfer per wallet	100,000	~$209
Batched through a disperse contract	~100	~$134
HoodLock	1	~$0.01

Measured on Robinhood Chain at 0.021 gwei. The HoodLock figure is the gas from a real airdrop transaction, 186,512 gas, and it does not grow with the list because the contract stores one 32-byte Merkle root rather than the list itself.

What you need

A wallet on Robinhood Chain (MetaMask, Rabby, Phantom, Robinhood Wallet or any WalletConnect-compatible wallet)
The token contract address, and enough of that token to cover the whole list
A small amount of ETH for gas. There is no platform fee
Your recipient list, up to 100,000 addresses per airdrop

Step-by-step: airdrop tokens in about a minute

Open the tool. Go to hoodlock.tech/app/airdrops and connect your wallet. The app adds Robinhood Chain automatically if your wallet does not have it yet.
Pick the token. Paste the contract address, or choose it from the dropdown listing every token in your wallet. The app reads the symbol, decimals and your balance from the chain.
Choose how much each wallet gets. Either the same amount for everyone, or a different amount per wallet.
Paste the recipient list. One address per line for an equal split, or address:amount per line to set each amount individually. Duplicates are shown to you rather than silently merged, so nothing looks like it went missing.
Set a deadline. 30, 90 or 180 days, or no deadline at all. This decides whether unclaimed tokens can ever come back to you, so it is the one choice worth thinking about.
Review and fund. The review sheet shows what leaves your wallet, how many wallets can claim, the fee read live from the contract, and what happens to anything unclaimed. Sign once and recipients can claim immediately.

Choosing a deadline

This is permanent, so it is worth one minute of thought.

With a deadline (minimum 7 days) you can sweep whatever nobody claimed back to your own wallet once it passes. Only you can call it.
With no deadline the airdrop stays claimable forever and the tokens can never return to you. Choose this only if you genuinely mean to give them up.

Either way, nobody including HoodLock can move the tokens before your deadline. That restriction is the reason a recipient can trust the page.

What recipients see

Every airdrop gets a public page at hoodlock.tech/airdrop/<id> that anyone can open without a wallet. It shows the token, the total funded, how many wallets can claim, how many already have, the deadline and the creator, all read live from the chain. Recipients open the app, connect, and see the exact amount they are owed with a single Claim button.

Share that link and it does the work: a wallet that is on the list sees its amount, a wallet that is not sees a plain answer instead of a promise.

Why this airdrop contract can be trusted

Verified source code — the contract at 0x6B1f…02E8 is verified on Blockscout, so anyone can read every line.
No admin path to a funded airdrop. No admin call can move, pause or redirect tokens somebody has already funded.
Sweep is creator-only and deadline-gated. Unclaimed tokens can only go back to the wallet that funded them, and only after the deadline that wallet chose.
The list is published, not held hostage. It lives at /api/airdrop/<id>/list.json and anyone can download it, so proofs can be rebuilt and claims submitted straight to the contract even if this website disappeared.
Every claim is proved. The contract checks a Merkle proof against the root before releasing a single token, so nobody who is not on the list can claim, and nobody can claim twice.
Fee-on-transfer tokens are rejected up front, rather than quietly leaving the last recipients unable to claim.

Common questions

How much does it cost to airdrop tokens on Robinhood Chain?

HoodLock charges no platform fee for airdrops at any list size. You pay network gas for one transaction, measured at about $0.01 on Robinhood Chain, whether the list has 10 wallets or 100,000.

How many wallets can one airdrop reach?

Up to 100,000 per airdrop. The cost does not change with the size of the list, because the contract stores a single 32-byte Merkle root rather than the list itself. For more than 100,000 recipients, split the list across two airdrops.

Do the tokens land in the recipients' wallets automatically?

No, and that is the design. The tokens sit in the contract and each recipient claims their own share, so nothing arrives in a wallet that never asked for it and you never pay gas for people who ignore the drop.

What happens to tokens nobody claims?

If you set a deadline, you can sweep the unclaimed remainder back to your own wallet once that deadline passes. Nobody else can call it, not even HoodLock. If you set no deadline, the airdrop stays claimable forever and the tokens can never come back.

Can recipients still claim if HoodLock disappears?

Yes. The full recipient list is published at /api/airdrop/<id>/list.json and is downloadable by anyone, so the Merkle proof can be rebuilt from the list and submitted straight to the contract without this website.
