Ink Token Manager: Change Your ERC-20 on the Ink Chain After Launch

Can you raise or lower your token's tax on Ink?

To change token tax on Ink, open the Tax tab of a token created with a tax. The tab holds 3 rates (buy, sell and transfer), each from 0% to 20%. Which way a rate can move depends on the tax type chosen at creation.

Changeable: every rate can go up or down whenever you like, with a ceiling of 20%, through "Update tax". Even at 0%, a changeable tax keeps its tab and can rise again later.

Fixed: rates only move down, through "Lower tax". Every cut is permanent, so a fixed tax lowered to 0% stays at 0%.

The buy and sell rates cover trades through the token's Uniswap v2 pools with ETH, USDC, USDT0 or USDC.e. The transfer rate covers sends from one plain wallet to another, with no contract on either side. Swaps through v3 or v4 pools pay no tax.

What pause, blacklist and raised limits do to trading on Ink

Anti-whale limits: for a token on Ink with this feature, "Max wallet" and "Max per trade" are each set as a share of supply. Either can rise as far as 100%, and every raise is permanent: you can never lower a limit. Removing both limits completely is a separate permanent step, under "Permanent changes". Max per trade counts buys and sells through the token's main pools (set at creation, the main pair among them), not wallet-to-wallet sends.

Pause: pausing token transfers stops every transfer, trades included, until you unpause.

Blacklist: a wallet on the blacklist can neither send nor receive the token, and you can remove it whenever you choose. The owner, the fee wallets and those main pools and routers can never be added.

Mint, burn and votes for an ERC-20 on Ink

A token created Mintable lets you mint more tokens on Ink. Type an amount, and the new tokens go to your wallet or to the address in "Send to". The supply cap set at creation still applies and cannot change; a token with no cap has no such ceiling. Minting to another wallet is refused if it would push that wallet past the max wallet limit.

On a token created Burnable, you can burn tokens on Ink from the owner wallet. The total supply drops by the amount burned, and a burn is permanent.

On a token created with Votes, holding the token gives no voting power until you delegate the balance. Delegating means choosing which address votes with it. "Activate my votes" delegates to yourself, and "Give votes" delegates to another address.

No Tokenry fee: you pay ETH gas for each change on Ink

Gas: Ink gas has 2 parts, an execution fee on Ink and a fee for posting the transaction to Ethereum (Ink docs on transaction fees). Both are paid in ETH, so the owner wallet needs some ETH on Ink.

Failed or declined: if a transaction reaches Ink and fails, nothing changes, yet its gas is spent (ethereum.org on gas). Declining the signature in your wallet sends no transaction, so no gas is paid.

Transfer ownership on Ink, to a wallet or a Safe multisig

Transfer token ownership on Ink by typing the new owner's address in "New owner address" and pressing "Start transfer". Ownership and every setting stay with you until that wallet accepts. Before then, "Cancel transfer" stops it, or you can start again with another address.

To finish, the new owner opens this manager, pastes the token address and presses "Accept ownership", paying a little ETH for gas. Because of this step, a mistyped or unreachable address can never become the owner. Once accepted, the transfer cannot be undone from your wallet. The new owner is then exempt from the token's tax and anti-whale limits instead of you, for the features the token has.

The new owner can also be a multisig. Safe runs on Ink, as Ink's multisig docs list, so a team can share control instead of trusting one key.

Renounce ownership of an Ink token as the last step

Renouncing ownership of a token on Ink is permanent. The token then has no owner, and nobody can change its tax or limits, mint, pause or blacklist again (OpenZeppelin's Ownable docs). If you may need control later, transfer ownership instead.

A token with a tax can still be renounced, and the tax stays. Its rates freeze at their current values, and collected tax is still paid out on sells while a buy or sell rate is above 0%. For a lower permanent rate, lower the tax before you renounce.

The manager refuses a renounce until the token is unpaused, its anti-whale limits are removed and its blacklist is empty. That way nothing stays paused, limited or blocked forever. To unlock "Renounce" under "Permanent changes", type the token's symbol with the same capitals.
