AirDrop Smart Contract

The AirDrop contract enables the efficient distribution of ERC-20 tokens to multiple addresses in a single transaction. This contract can be used for airdrops, distributing rewards, or any scenario requiring token transfers to multiple recipients.

Features

• Batch Token Distribution: Distribute ERC-20 tokens to multiple recipients in a single transaction.
• Flexible Amounts: Specify individual token amounts for each recipient.
• Address Verification: Ensures that the provided token address is a valid contract.
• Ownership Control: Only the contract owner can initiate airdrops.

Contract Functions

constructor()

• Description: Initializes the AirDropRc31 contract. No parameters are required for deployment.

doAirDrop(address[] memory _address, uint[] memory amounts, address tokenInstance)

• Description: Transfers specified amounts of an ERC-20 token to a list of recipient addresses.
• Parameters:
  • _address - An array of addresses to receive tokens.
  • amounts - An array of token amounts corresponding to each recipient.
  • tokenInstance - The address of the ERC-20 token contract.
• Returns: A boolean value indicating whether the airdrop was successful.
• Requirements:
  • The _address and amounts arrays must have the same length.
  • tokenInstance must be a valid ERC-20 token contract.

Example Usage

1. Deploy the contract.
2. Call the doAirDrop function, passing in:
   • A list of recipient addresses (_address).
   • The amounts of tokens to send to each recipient (amounts).
   • The address of the ERC-20 token contract (tokenInstance).

Access Control

Only the contract owner can initiate the airdrop. This ensures secure and controlled token distribution.

Prerequisites

• Solidity version ^0.8.1
• An ERC-20 token contract for the token distribution.

Example

address[] memory recipients = [0xRecipientAddress1, 0xRecipientAddress2];
uint[] memory amounts = [100 * 10 ** 18, 50 * 10 ** 18];
airDropInstance.doAirDrop(recipients, amounts, tokenAddress);

Important Notes

1. Ensure that the contract has sufficient allowance to transfer the specified amounts from the sender’s wallet.
2. The function will revert if any transfer fails.
