/**
* @dev Hook that is called before any transfer of tokens. This includes
* minting and burning.
*
* Calling conditions:
*
* - when `from` and `to` are both non-zero, `amount` of ``from``'s tokens
* will be to transferred to `to`.
* - when `from` is zero, `amount` tokens will be minted for `to`.
* - when `to` is zero, `amount` of ``from``'s tokens will be burned.
* - `from` and `to` are never both zero.

GOING FROM A FUN IDEA, TO A ROBUST CONTRACT. A-TEAM.
We scrapped the chain looking for inspiration when it comes to the biggest problems surrounding MEME-token launches (swingers, whales and bots). Our hand-made contract is a guarantee that our investors can’t be botted and that no whales can’t control our supply. Combining a solid contract to a community-driven approach, we’re set up for success.

Rice Inu Token
Going from a fun idea, to a robust contract. A-Team.
We scrapped the chain looking for inspiration when it comes to the biggest problems surrounding MEME-token launches (swingers, whales and bots). Our hand-made contract is a guarantee that our investors can't be botted and that no whales can't control our supply. Combining a solid contract to a community-driven approach, we're set up for success.

/*
* @dev This is the Axia Protocol Staking pool 3 contract (SWAP Pool),
* a part of the protocol where stakers are rewarded in AXIA tokens
* when they make stakes of liquidity tokens from the oracle pool.
* stakers reward come from the daily emission from the total supply into circulation,
* this happens daily and upon the reach of a new epoch each made of 180 days,
* halvings are experienced on the emitting amount of tokens.
* on the 11th epoch all the tokens would have been completed emitted into circulation,
* from here on, the stakers will still be earning from daily emissions
* which would now be coming from the accumulated basis points over the epochs.
* stakers are not charged any fee for unstaking.

* @dev Implementation of the {IERC20} interface.
*
* This implementation is agnostic to the way tokens are created. This means

* For a generic mechanism see {ERC20PresetMinterPauser}.
*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.
