How much gas does an ERC20 deploy use on Ethereum?
A Standard token uses about 730,000 gas, and an Advanced token with taxes about 5.5 to 6.3 million. Your gas cost in ETH is that number times the gas price when you sign, which rises with network congestion. The 0.01 or 0.03 ETH creation fee comes on top.
Can I test it free on Sepolia first?
No, the tool deploys only to Ethereum mainnet (chain ID 1), with no testnet option. A Sepolia token is a separate contract and would not carry over. To rehearse, fill in the form and open the review screen; declining to sign costs nothing.
What if Etherscan does not verify my source code?
Verification starts from this page once the deploy confirms, so closing the page early can stop it. Tokenry then submits the source automatically, trying up to 3 times, and a unique ID per contract makes the match exact. If the source has not appeared a few minutes later, send us the contract address on Telegram and we will verify it.
Where should a tax token's first pool go?
A token with any Tokenry tax should open its first pool on V2 against ETH. Its buy and sell taxes apply on the V2 pair it created at launch, and on another pool only if the owner marks it. The tool blocks V3 and V4 only when it measures a transfer tax, not for buy and sell taxes alone. The Ethereum liquidity pool creator covers the Uniswap version choice for other tokens.
Who controls the token, Tokenry or my wallet?
Your wallet does, and the explorer shows it. Its Read Contract tab lists your signing address as owner, and right after launch, the Holders tab shows the full token supply at that address. Tokenry's factory only creates the token and forwards the creation fee. Your keys never leave your device.
What can the owner still change after launch?
A Standard token's owner can only transfer or renounce ownership. On a tax token, the Token Manager lets the owner change the rates (20% cap each) and who is exempt, for gas only. Owners can mint on a Mintable token up to any cap, change fee wallets and switch the swap router on tax tokens. Changing or switching off the anti-whale limit takes a direct contract call. Renouncing ends it all.
Do I lose the token creation fee if the deploy fails?
You keep the fee, but not the gas. The fee is sent inside the same transaction, and the factory forwards it only after your token contract is deployed. A revert leaves it in your account. Try Again reopens the review screen with every field kept; first tap View transaction to check that the earlier attempt failed.
Why does Etherscan show a warning or no logo?
The explorer can label a token as possibly impersonating a well-known cryptocurrency. It did so with our test token simply named "Token", so pick a distinct name. The explorer's token information update sets the logo and links. Since the factory created the token, sign the explorer's message from the owner address and send it through the explorer's contact form to prove ownership.
