Solana Airdrop - Multisender

The multisender tool, often referred to as an airdrop tool, is a great utility that allows users to send tokens to multiple wallet addresses in batches. This is especially useful when:

• Distributing airdrops to community members
• Paying multiple team members in project tokens
• Rewarding contest winners or participants
• Managing token distribution for investors

The tool significantly reduces transaction time and Solana network fees compared to sending tokens individually, making it an essential companion to the 20lab token generator for efficient token management.

No, there is no overall address limit for the multisender tool. However, large distributions are automatically split into batches up to the transaction size limit for optimal efficiency on the Solana network.

This batching approach ensures:

• Reliable transaction processing and efficient gas usage
• Compatibility with Solana's transaction size limitations
• Ability to handle distributions of any size

Yes, the multisender tool is compatible with all SPL tokens on the Solana blockchain, including:

• Classic SPL tokens
• SPL tokens from the Token-2022 program, such as those created on 20lab
• Popular tokens such as USDC, BONK, etc.

The tool works with any token that follows the Solana Program Library (SPL) token standard, making it versatile for different distribution needs, regardless of token type or specification.

To track your batch transactions:

1. Click the "Check progress" button in the sidebar menu
2. View the status of all your pending and completed transactions
3. Each transaction record shows the number of transactions it contains and the cumulative amount to be distributed

This tracking interface makes it easy to monitor multiple distribution transactions and ensure that all your token transfers are processed correctly.

The 20lab multisender tool supports 2 convenient methods for importing recipient addresses:

• CSV Upload - Import a CSV file with wallet addresses and token amounts
• Text Input - Paste a list of addresses and amounts in the specified format

The tool automatically validates all addresses to ensure they are valid Solana wallet addresses, helping you avoid errors during your token distribution.

The multisender tool involves two types of fees:

• Network Fees - Standard Solana transaction fees (typically a fraction of SOL) paid to the network
• Service Fee - 20lab fee based on the amount of operations disclosed in pricing

Compared to individual transfers, the multisender significantly reduces the total transaction fees for large distributions. The exact fee amount is always clearly displayed before you confirm the transaction, ensuring complete transparency.

Processing time depends on several factors:

• Number of Recipients - Larger batches are processed in sequential transactions
• Solana Network Congestion - Transaction finality may take longer during peak network usage
• Token Type - Standard SPL tokens process faster than tokens with complex programs

In typical conditions, each batch completes in approximately 10-15 seconds, with the entire distribution processing sequentially. You can monitor progress in real-time through the transaction tracking window.

If a batch transaction fails during distribution:

• Only the specific failed batch is affected; other batches can still be processed
• You can easily retry the failed batch at a later time
• The status of each batch is clearly displayed in the transaction monitor

Common reasons for failure include insufficient token balance, insufficient SOL for transaction fees, frozen recipient Associated Token Accounts (ATAs), or tokens with non-transferable extensions.
