Ethereum Token Manager: Owner Settings for Your Tokenry ERC-20

In Tokenry's Ethereum token manager, the wallet that deployed an ERC-20 through Tokenry's factory on Ethereum mainnet changes its settings with no code, as long as it is still the owner. Each change is one transaction to the token's smart contract. It needs no token approval and carries no Tokenry fee, so gas, the network fee in ETH, is the only cost.

Why Tokenry

  • No Code Required

    Create and launch tokens without writing any code. Visual configuration for all features.

  • Fully Transparent

    All token data is publicly visible and verifiable on block explorers.

  • Multi-Chain

    Works on Solana and 8 EVM chains, including Ethereum, Base, Arbitrum, Polygon and BNB Chain.

  • Full Ownership

    You have full control. We never hold your keys, tokens, or authority.

How it works

Changing one setting on your Ethereum ERC-20

  1. 1

    Open the page with your deployer wallet on Ethereum

    Settings appear only while that wallet is still the token's owner and connected to mainnet.

  2. 2

    Choose the token card and a settings tab

    Pick the token, then the tab that holds the setting, such as Tax Settings or Mint.

  3. 3

    Enter the new value and press its button

    Each section has its own button, such as Update tax rates or Mint tokens. Pressing it opens your wallet straight away, without a review screen in Tokenry.

  4. 4

    Wait for Confirmed on-chain and the Etherscan link

    When the transaction confirms, the section shows Confirmed on-chain with a View transaction link to Etherscan, and the page reloads the token's values.

Frequently Asked Questions

Something not covered here? Contact support.

Which ERC-20 tokens show up in the manager?

Only tokens the connected wallet deployed through Tokenry's factory on Ethereum mainnet. There is no field to paste a token address, so an ERC-20 from another tool will not appear. If a token is missing, connect the wallet that deployed it.

What does my wallet sign when I change a setting on Ethereum?

One transaction that calls a single function on your token's smart contract, such as setFeeConfiguration for tax rates or mint for new supply. It sends 0 ETH. Tokenry never holds the owner wallet's private key. Before you confirm, check that the wallet prompt shows your token's contract address and a gas estimate you accept.

What stays in place after I renounce ownership on Ethereum?

Tax rates, fee exemptions and the DEX router used for fee swaps stay at their current values for good. Automatic fee processing keeps running if it was on. Minting and every other owner change stop, and the contract's owner is set to the zero address. Renouncing cannot be undone, so the Ownership tab shows the renounce button only after you click "I understand, show the button".

Does a new owner have to accept an ownership transfer?

Transfer ownership takes effect in one step, when the transaction confirms, with nothing for the new wallet to accept. A wrong address cannot be undone. The deploying wallet stays exempt from the tax and the holding limit, where the token has them. The new owner cannot open the token in this manager yet, since the list goes by the deploying wallet. It would call the owner functions directly, for example from the Write Contract tab on Etherscan once the contract shows as verified there.

What can the Rescue tab recover from an Ethereum token contract?

ETH held by the token contract, and other ERC-20 tokens sent to its address. It cannot withdraw the token itself from the contract, where collected tax is held until the contract processes it. Rescue appears only on tokens with the tax feature, and the ERC-20 amount is typed in raw units, the token's smallest unit before decimals.

More about the Ethereum Token Manager

01

Ethereum token manager tabs by creation feature

Which tabs a token gets depends on the features it was deployed with. A Standard token has Ownership, plus Burn if it is burnable. A token that needs a feature it lacks takes a new deploy with the ERC20 token creator.

On mintable tokens, the Mint tab sends new supply to any address, your own wallet by default. On anti-whale tokens, the Anti-Whale tab exempts a wallet from the holding limit. The tax feature brings four tabs: Tax Settings, Swap Settings, LP Pools and Rescue.

The contract template has no function to pause trading, blacklist a wallet, freeze balances or force a transfer, so no tab offers them. The token manager hub lists the pages for Tokenry's seven other EVM chains.

02

Tax changes on a live Ethereum token

A new tax rate applies from the next trade on the same token address, with no redeploy, so holders and pools stay where they are. Buy, sell and transfer taxes go up to 20% each. The burn, liquidity and marketing split must total 100%, and up to 10 marketing wallets can share the marketing part.

Fee exemptions turn the tax off for one address, such as the Ethereum multisender contract before an airdrop. On a token that also has a holding limit, exempt the multisender from the limit too.

Buy and sell tax applies only to trades through pairs marked as LP pairs. The WETH (wrapped ETH) pair created at deploy, on Uniswap v2 with the default router, is marked already. Any other Uniswap v2 pair, such as a USDC pair you open later with the Ethereum liquidity pool creator, needs marking in LP Pools too, or its trades pay the transfer rate. Do not mark a v3 or v4 pool, since taxed sells through it would revert. Marked pairs are also exempt from the holding limit.

Swap Settings controls when the contract processes collected tax, swapping it for ETH unless marketing fees are paid in the token, at a threshold from 0.05% to 1% of supply. Automatic processing runs on a taxed sale once the contract holds the threshold amount. The same tab can turn it off, change the DEX router or change the wallet that receives the LP tokens.

03

Changes the Ethereum token contract rejects

A reverted transaction changes nothing on the token, but the gas it used is still spent. The tab then asks you to check the values and that the wallet still owns the token.

The contract rejects a swap threshold or a marketing wallet count past the limits above, and any call from a wallet that is no longer the owner. The page itself stops a tax rate over the cap, or a mint past the supply cap, before the wallet opens.
