What Is a Token Airdrop?
A token airdrop is a distribution of tokens to multiple wallet addresses — typically as a reward for early community members, to bootstrap holder distribution, or as part of a marketing campaign. Instead of users buying tokens, they receive them for free (or for completing simple tasks).
On EVM chains like Robinhood Chain, airdrops are executed via a multisender smart contract — a contract that accepts a batch of addresses and amounts, then executes all transfers in one or a few transactions. This is much more efficient than individual transfers (which would require hundreds of separate MetaMask confirmations).
Why Airdrop on Robinhood Chain?
- Low gas costs: Robinhood Chain's L2 architecture means gas per transfer is extremely low. Large airdrops to thousands of wallets cost a fraction of what they would on Ethereum L1.
- Growing user base: Robinhood's 25M+ retail user base creates a natural audience for Robinhood Chain projects. Airdrops to on-chain Robinhood Chain wallets reach an already-interested demographic.
- Builds holder distribution: A token with 10,000 holders is harder to manipulate and more credible than one with 50. Airdrops create that distribution from day one.
- Creates on-chain activity: If you're airdropping in a context where the Robinhood Chain team is watching for protocol activity (see our airdrop farming guide), both sending and receiving large batches of transactions is on-chain activity worth recording.
What You Need
- A deployed ERC-20 token on Robinhood Chain. If you haven't deployed yet, see our token creation guide.
- A list of recipient wallet addresses and how many tokens each should receive.
- ETH on Robinhood Chain for the multisender fee and gas.
- A non-custodial multisender contract compatible with Robinhood Chain (any EVM-compatible multisender that supports custom chain IDs).
CSV Format
Most multisender contracts expect a simple two-column CSV: wallet address and token amount. The standard format:
0xabc...123,1000
0xdef...456,500
0xghi...789,2000
Some tools accept the format address=amount per line, or a comma-separated list of address:amount pairs. Check the documentation for the specific multisender you're using.
Common CSV mistakes:
- Including a header row (most tools don't want one — just data rows)
- Extra spaces before or after addresses or amounts
- Duplicate addresses (the tool may error or send twice to the same wallet)
- Wrong token amounts (remember to account for decimals if entering raw amounts vs. human-readable amounts)
Decimal amounts: ERC-20 tokens use 18 decimal places by default. If you want to send 1,000 tokens to an address, the raw amount is 1000 * 10^18. Most user-friendly multisender tools let you enter the human-readable amount (1000) and handle the conversion — but always verify before confirming.
Step-by-Step Airdrop Guide
Step 1 — Prepare your recipient list: Compile all wallet addresses and amounts in a CSV file. Remove duplicates, verify all addresses are valid Ethereum/EVM format (starting with 0x, 42 characters), and double-check total supply matches your airdrop allocation.
Step 2 — Choose a multisender contract: Use a non-custodial multisender contract that supports Robinhood Chain (Chain ID 4663). Verify the contract is published and verified on Blockscout before trusting it with your tokens.
Step 3 — Upload your CSV: Connect your wallet (set to Robinhood Chain) to the multisender interface. Upload your CSV file. The tool will display the parsed list of addresses and amounts — review it carefully before proceeding.
Step 4 — Approve token spending: The multisender contract needs permission to spend your tokens. This "approve" transaction is separate from the actual send and costs a small gas fee. Approve exactly the amount you plan to airdrop (not unlimited, for security).
Step 5 — Confirm the batch send: Review the final summary: number of recipients, total tokens to be sent, fee (0.0001 ETH per recipient is typical), and estimated gas. Confirm in MetaMask. For large lists, the tool may automatically split into multiple batches of 100-500 addresses each.
Step 6 — Verify on Blockscout: After the transaction(s) confirm, check a few recipient addresses on robinhoodchain.blockscout.com to confirm they received the correct amounts.
Cost Breakdown
| Item | Cost |
|---|---|
| Multisender fee per recipient | ~0.0001 ETH per wallet |
| Gas per batch transaction | Very low on Robinhood Chain L2 |
| Token approval gas | ~0.0002 ETH (one-time per airdrop) |
| 1,000 recipient airdrop (total) | ~0.1 ETH + gas |
| 10,000 recipient airdrop (total) | ~1 ETH + gas |
Safety Checklist
Before confirming any multisender transaction:
- Verify the multisender contract is source-code verified on Blockscout
- Confirm it's non-custodial — it should only access tokens you've explicitly approved
- Check the "approve" amount matches only the airdrop total, not unlimited
- Verify the displayed recipient list matches your CSV before confirming
- Test with a small batch of 3-5 addresses first before running the full list
FAQ
How do I send tokens to multiple wallets on Robinhood Chain?
Use a non-custodial multisender contract. Upload your CSV with addresses and amounts, approve token spending, and confirm the batch transfer in one transaction.
How much does an airdrop cost on Robinhood Chain?
Approximately 0.0001 ETH per recipient wallet, plus minimal gas for the batch transactions. For 1,000 wallets, expect around 0.1 ETH in fees plus gas.
Is running an airdrop on Robinhood Chain safe?
Yes, if you use a verified, non-custodial multisender. The contract only accesses the tokens you explicitly approve. Always verify the contract on Blockscout and test with a small batch first.
What format does the airdrop CSV need to be in?
Standard format: wallet_address,amount per row. No header row. Verify the specific format required by the multisender you use.
Do airdrop recipients need ETH to receive tokens?
No. Receiving ERC-20 tokens requires no ETH. The sender pays all gas. Recipients only need ETH if they want to transfer or sell the tokens later.
How many wallets can I airdrop to in one transaction?
Most multisender contracts automatically batch large lists into groups of 100-500 per transaction. For very large airdrops (10,000+), expect multiple transactions across several blocks.
