When you airdrop tokens to hundreds of wallets, two things matter most: gas cost and reliability. One-Click Sender is a tiny batch-transfer contract that cuts fees and guarantees an all-or-nothing result — no half-finished distributions. Below is a clean explanation of how it works, what it really saves, and how it behaves on HyperEVM.

1. Why Single ERC-20 Transfers Are Expensive

A normal transfer pays for two gas layers

• EVM base fee: 21 000 gas just to land the tx in a block

• Token logic: ≈ 45 000 gas to update storage, emit events, run checks

Total per wallet: ≈ 66 000 gas. Do that 200 times and you burn ≈ 13.2 million gas — over a quarter of Ethereum’s 30 M-gas block limit.

2. What the Batch-Transfer Contract Does

function batchTransfer(    address token,    address[] calldata recipients,    uint256[] calldata amounts) external {    require(recipients.length == amounts.length, "Length mismatch");    for (uint256 i; i < recipients.length; ++i) {        bool ok = IERC20(token).transferFrom(            msg.sender,            recipients[i],            amounts[i]

You pay the 21 000-gas base fee once, not per recipient. The loop adds only a few hundred gas overall, and any failed transfer reverts the entire batch automatically.

3. Real-World Gas Savings (200 wallets)

• Regular method: ≈ 13 200 000 gas

• One batch call: ≈ 9 100 000 gas

• Saved: ≈ 4.1 million gas (≈ 31 %)

The saving comes almost entirely from consolidating the 21 000-gas base fee (4.2 M gas removed) with only ~0.1 M gas of loop overhead added back.

At 1 Gwei gas price, this equals 0.0041 ETH (about $16.4), a 31% reduction, mainly from consolidating transaction base fees.

4. How It Fits HyperEVM

HyperEVM has two lanes

• Small blocks: 2 M gas, a few-second confirmation

• Big blocks: 30 M gas, ~60 s confirmation

A 200-way batch (~9.1 M gas) can’t fit in a 2 M small block. One-Click Sender therefore caps each batch at 40 addresses (≈ 1.82 M gas). A 200-wallet airdrop becomes five small-block transactions that still confirm in under 30 seconds — faster than waiting a full big-block minute.

5. Five-Step, Five-Minute Workflow

1. Connect wallet.

2. Upload a CSV of recipient addresses and amounts.

3. Approve the token (one tx per token).

4. Preview the exact gas fee.

5. Sign, send, and track everything through a single explorer link.

6. Bottom Line

Batch transfers compress hundreds of expensive, failure-prone calls into one atomic operation. One-Click Sender delivers ~30 % gas savings on Ethereum, small-block-safe batching on HyperEVM, and a UI so simple non-developers can finish an airdrop during a coffee break. Prepare your CSV, click once, and let your next distribution run itself — cheaper, faster, and with zero partial failures.
