Airdrops

Distribute tokens to thousands of addresses in batch transactions. CSV upload, gas-efficient, multi-chain.

Overview

ChainPortal's airdrop feature lets you distribute tokens to multiple recipients in a single batch transaction, saving significant gas compared to individual transfers.

How Airdrops Work

Select your token

Choose the token you want to airdrop from your deployed assets.

Prepare recipient list

Upload a CSV file with addresses and amounts, or enter them manually.

Review distribution

Verify the total amount, number of recipients, and estimated gas cost.

Approve token spending

Approve the airdrop contract to spend your tokens (ERC20 approval).

Execute airdrop

Send the batch transaction. All recipients receive tokens in one transaction.

CSV Format

Prepare your airdrop CSV with two columns:

address,amount
0x1234...abcd,1000
0x5678...efgh,500
0xabcd...1234,2500

Tip: Amounts should be in human-readable format (e.g., 1000 for 1000 tokens). ChainPortal handles decimal conversion automatically.

Supported Ecosystems

Ecosystem	Max Recipients per TX	Gas per Recipient
EVM	~200	~$0.01-0.50
Solana	~50	~$0.001

Best Practices

Test first -- Always test with a small batch on testnet before mainnet
Check balances -- Ensure you have enough tokens AND gas for the full batch
Verify addresses -- Double-check all recipient addresses are valid
Split large airdrops -- For 1000+ recipients, split into multiple transactions
