Send Tokens in Bulk with Low Fees and Fast Delivery: The Ultimate Airdrop Tool for 2024

#ethereum #smartcontract #nft #solidity

Airdropping tokens is an effective strategy to engage your community, reward contributors, or distribute assets. However, manual distribution can be time-consuming and costly due to high transaction fees. The BulkSender smart contract automates this process, streamlining token distribution across multiple addresses on any EVM-compatible blockchain.

🚀 Key Features

Native Token Transfers: Send ETH or the native token of an EVM chain to multiple addresses in a single transaction.
ERC-20 Token Transfers: Distribute fungible tokens either equally or in varying amounts.
ERC-721 Token Transfers: Airdrop unique NFTs.
ERC-1155 Token Transfers: Handle both fungible and non-fungible tokens in batch mode.

🎯 VIP System

BulkSender offers a VIP system where users can pay a one-time fee to eliminate per-transaction fees, making it ideal for frequent token distributors.

📚 How It Works

1. Native Token Airdrop

Use the bulkTransfer function to airdrop native tokens (e.g., ETH) to a list of receivers.

function bulkTransfer(address[] calldata _receivers, uint[] calldata _values) external payable {
    // Transfers ETH to multiple addresses
}

2. ERC-20 Token Airdrop

Equal Distribution

The bulkTransferERC20 function sends the same amount of tokens to all recipients, optimizing gas fees.

function bulkTransferERC20(address _tokenAddress, address[] calldata _receivers, uint _value) external payable {
    // Sends the same amount of tokens to all recipients
}

3. ERC-721 NFT Airdrop

The bulkTransferERC721 function airdrops NFTs to multiple recipients.

function bulkTransferERC721(address _tokenAddress, address[] calldata _receivers, uint[] calldata _tokenIds) external payable {
    // Transfers NFTs to multiple recipients
}

4. ERC-1155 Token Airdrop

This function distributes ERC-1155 tokens to multiple addresses.

function bulkTransferERC1155(
    address _tokenAddress,
    address[] calldata _receivers,
    uint[] calldata _tokenIds,
    uint[] calldata _values
) external payable {
    // Distributes ERC-1155 tokens
}

📖 How to Use BulkSender

Step 1: Prepare a CSV File

Create a CSV file with recipient addresses and corresponding amounts. For ERC-20 tokens, the format should be:

0xa0BfF9CA8aF0649eB056cA1a902b559Da97FFde9, 1 0xD126FC84717D6e9D97027016Abcaf0B57e6042D2, 20

Step 2: Configure BulkSender

Input your token address into the BulkSender application and follow the provided steps. Ensure the contract is adequately funded for native token transfers.

Step 3: Execute the Airdrop

Once configured, initiate the airdrop. You can verify the transaction on Etherscan.
