Cronos Token Manager: Tax Rates, Minting and Ownership of a CRC-20

Change token tax on Cronos after launch

A Cronos token created with a tax has a Tax tab in the Cronos token manager while the token has an owner. There you change its buy, sell and transfer rates, each from 0% to 20%. Once the token is renounced, at creation or later, its rates never change. The kind of tax chosen in the Cronos token creator decides what you can change now.

Changeable: you can raise or lower each rate at any time, up to 20%, with "Update tax". A changeable tax set to 0% can be raised again later.

Fixed: you can only lower the tax, with "Lower tax". Each cut is permanent, so a fixed tax never goes back up, even from 0%.

Buys and sells pay the tax through the token's V2 pools with CRO, USDC, USDC.e or USDT. The transfer tax applies only to sends between 2 plain wallets, where neither side is a contract. Trades through a V3 pool pay no tax.

Mint more tokens or burn supply on Cronos

You can mint more tokens on Cronos if the token was created as Mintable. New tokens go to your wallet, or to the address you enter in "Send to". You can mint up to the supply cap set at creation, or without a limit if the token has no cap. A mint that would put another wallet over the max wallet limit is refused before your wallet asks you to sign.

To burn tokens on Cronos, the token must be Burnable and the owner wallet must hold some of it. A burn destroys tokens from that wallet and permanently lowers the supply by the same amount.

Max wallet, max per trade, pause and blacklist on Cronos

Anti-whale limits: a Cronos token created with Anti-whale has a "Max wallet" and a "Max per trade" limit. You set each limit as a share of supply, but the token stores it as a token amount. After a mint, the same limit is a smaller share of the new supply. You can raise either one up to 100%, but you can never lower it, so each raise is permanent. Removing the limits is a separate permanent step under "Permanent changes" in the manager.

Pause: "Pause transfers" stops every transfer of the token, trades included, until you press "Unpause".

Blacklist: a blacklisted wallet cannot send or receive the token, and you can take a wallet off the list at any time. The token's main DEX pools, the DEX routers and the current owner cannot be blacklisted.

If your token has a Voting tab, you can activate the votes of your own balance or give them to another address.

Give your Cronos token a new owner wallet

To transfer token ownership on Cronos, enter the "New owner address" and press "Start transfer". You stay the owner, with every setting, until the new owner accepts.

The new owner connects their wallet to the Cronos token manager, pastes the token address and presses "Accept ownership". Accepting is their own transaction and needs a little CRO for gas. Because of these 2 steps, a mistyped or unreachable address can never become the owner. Until the new owner accepts, you can press "Cancel transfer" or start again with another address.

After the transfer, the new owner, not you, is exempt from the token's tax and anti-whale limits, where the token has them.

What renouncing a Cronos token locks in place

Before you renounce ownership of a Cronos token, know that a renounce is permanent. The token then has no owner, so nobody can change the tax or the limits, mint, pause or blacklist again (OpenZeppelin docs). If the token may need an owner later, transfer ownership to another wallet instead.

A tax does not block a renounce. The rates stay at their current values forever, and collected tax keeps paying out on sells while a buy or sell tax is set. Lower the tax first if you want a lower permanent rate.

A renounce goes through only once the token is unpaused, its anti-whale limits are removed and its blacklist is empty, so nothing stays blocked forever. "Renounce" sits under "Permanent changes" in the manager and unlocks only after you type the token's symbol exactly, capitals included.

CRO gas for each change to a Cronos token

Tokenry fee: none for any change in the Cronos token manager.

Gas: every change is a transaction paid in CRO, the gas coin on Cronos (Cronos docs), so the owner wallet needs some CRO.

Accepting ownership: the new owner pays their own CRO gas.

Failed or rejected: a transaction that lands and fails changes nothing but still uses gas (ethereum.org). A signature you reject in your wallet sends nothing and costs nothing.
