Question 1

What network does the app use?

Accepted Answer

BNB Chain (Mainnet). The app will prompt a network switch if needed.

Question 2

Which token is used for purchases?

Accepted Answer

USDT with 18 decimals. Other decimal variants (e.g., 6-decimal tokens) are not supported by the StageSale contract.

Question 3

What is BATACoin technically?

Accepted Answer

An ERC-20 token with Permit, Votes, Pausable, and AccessControl. Fixed supply: 880M BATA, 18 decimals.

Question 4

Where can I see important addresses?

Accepted Answer

See "Safe Wallets & Smart Contracts" inside the app. You can also review our docs.

Question 5

How do I buy?

Accepted Answer

Click on "BUY (USDT)" → approve USDT (first time) → "Buy Tokens" (you can set max tokens to buy).

Question 6

How are vesting rules applied?

Accepted Answer

After purchase, your tokens enter a vesting period based on the current stage rules (cliff then linear unlock).

Question 7

Are there whitelist and stage settings?

Accepted Answer

Yes. Stages have separate price, softcap, hardcap, whitelist settings, and separate vesting schedules. Check stage info in the purchase modal.

Question 8

Is there a per-wallet cap and minimum?

Accepted Answer

Yes. Check the StageSale UI. Per-stage limits and minimums are enforced in the smart contract. Buying outside this will revert.

Question 9

Where do presale funds go?

Accepted Answer

Directly to the BATACoin safe wallet, also visible at batacoin.io/Safe-wallets-and-smart-contracts.

Question 10

Where are my tokens after buying?

Accepted Answer

In your wallet, but locked under the vesting schedule. Check the new software vesting conditions. If you buy multiple times during the same stage, vestings are merged.

Question 11

Why did my transaction fail?

Accepted Answer

Check your USDT balance, allowance, and BNB for gas. Also ensure you meet whitelist and stage criteria.

Question 12

How does stage logic work?

Accepted Answer

Stages can be paused, finished, or at capacity. When softcap is reached and stage ends, presale auto-progresses. Presales don't roll-over like whitelists (old stage = old whitelist).

Question 13

Should I transfer USDT directly to the contract?

Accepted Answer

No. Always use the dashboard interface, or the "buy" function contract, or otherwise your funds will be trapped without receiving tokens.

Question 14

How much gas will I pay?

Accepted Answer

Typically 0.001-0.003 BNB depending on network congestion. If USDT approval is needed, that's an extra transaction.

Question 15

Where can I view the contracts?

Accepted Answer

See the "Safe Wallets & Smart Contracts" page. The BATA token, StageSale, and VestingScheduler are deployed on BNB Chain BSCscan.

Question 16

Can anyone freely move USDT from the contract?

Accepted Answer

No. Only the contract owner (multisig) can withdraw funds, and only to predefined safe wallets.

Question 17

Why do I see USDT with 18 decimals?

Accepted Answer

BATACoin's USDT-compatible contracts use the 18-decimal version of USDT. This is correct behavior.

Question 18

How do I verify ABIs/contracts?

Accepted Answer

ABIs are published in documentation. All contracts are verified on BSCscan.

Question 19

How is vesting calculated?

Accepted Answer

Vesting rules (cliff, duration) are defined per stage in VestingScheduler. Your claim amount is based on time passed since vesting start.

Question 20

"Insufficient allowance" or "transfer not approved"

Accepted Answer

You need to approve USDT before buying. Click "Approve USDT" first.

Question 21

"Chain mismatch" in my wallet

Accepted Answer

Switch your wallet network to BNB Chain (Mainnet). The app will prompt if not connected.

Question 22

Transaction reverted after "low buying"

Accepted Answer

You may be below the minimum per-wallet threshold for this stage. Check stage info.

Question 23

"IsWhitelisted" but I got rejected

Accepted Answer

Perhaps you're on a different stage's whitelist. Not all stages share whitelists. Check admin for manual add.

Question 24

"Gas estimated" but it fails anyway?

Accepted Answer

Network congestion or nonce issues. Reset your wallet nonce or wait a moment.
