Spring is a season of flowers which arrives after winter and before the summer,
During the spring season, weather becomes pleasant and the days grow longer.
It is the season of fragrance, beauty, fresh leaves, and flowers.
Ethereum finally met the Spring!!!!

"Spring is a season of altcoins which arrives after bearish market and before the bullish market,
During the alt season, the market becomes profitable and the chart looks green.
It is the season of POMP, SHILL, GREEN CHART, and MEME"

// Methodology for Calculating LP Token Price //
// //
///////////////////////////////////////////////////////
// A naïve approach to calculate the price of LP tokens, assuming the protocol
// fee is zero, is to compute the price of the assets locked in its liquidity
// pool, and divide it by the total amount of LP tokens issued:
//
// (p_0 * r_0 + p_1 * r_1) / LP_supply (1)
//
// where r_0 and r_1 are the reserves of the two tokens held by the pool, and
// p_0 and p_1 are their respective prices in some reference unit of account.
//
// However, the price of LP tokens (i.e. pool shares) needs to be evaluated
// based on reserve values r_0 and r_1 that cannot be arbitraged, i.e. values
// that give the two halves of the pool equal economic value:
//
// r_0 * p_0 = r_1 * p_1 (2)
//
// Furthermore, two-asset constant product pools, neglecting fees, satisfy
// (before and after trades):
//
// r_0 * r_1 = k (3)
//
// Using (2) and (3) we can compute R_i, the arbitrage-free reserve values, in a
// manner that depends only on k (which can be derived from the current reserve
// balances, even if they are far from equilibrium) and market prices p_i
// obtained from a trusted source:
//
// R_0 = sqrt(k * p_1 / p_0) (4)
// and
// R_1 = sqrt(k * p_0 / p_1) (5)
//
// The value of an LP token is then, replacing (4) and (5) in (1):
//
// (p_0 * R_0 + p_1 * R_1) / LP_supply
// = 2 * sqrt(k * p_0 * p_1) / LP_supply (6)
//
// k can be re-expressed in terms of the current pool reserves r_0 and r_1:
//
// 2 * sqrt((r_0 * p_0) * (r_1 * p_1)) / LP_supply (7)
//
// The structure of (7) is well-suited for use in fixed-point EVM calculations, as the
// terms (r_0 * p_0) and (r_1 * p_1), being the values of the reserves in the reference unit,
// should have reasonably-bounded sizes. This reduces the likelihood of overflow due to
// tokens with very low prices but large total supplies.

*
* 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.

*
* 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}.

Website - Being created in the dojo.
STEALTH LAUNCH NINJA STYLE.
ShibNinja is the secret child of Shiba Inu. He’s pretty elusive and can’t often be found. Due to his private life he will be stealth launching, with no prior announcements and no prior marketing.
However, he has big plans for after launch and is bringing his entire Dojo with him. It’s taken years of skill to get to this point, and he is now ready for launch.
ShibNinja is not greedy and is only keeping 5% tokens for his hard-working team. Liquidity will be locked + Ownership Renounced after launch.

🥩 1,000,000,000,000 token supply
🥩 Sell will be disabled for 60 seconds after launch to blacklist bots and will be automatically lifted by the contract afterwards
🥩 FIRST TWO MINUTES: 3000000000 max buy / 60-second buy cooldown (these limitations are lifted automatically two minutes post-launch)
🥩 15-second cooldown to sell after a buy, in order to limit bot behavior. NO OTHER COOLDOWNS, NO COOLDOWNS BETWEEN SELLS
Maximum Wallet Token Percentage for Whale Control
🥩 For the first 15 minutes. there is a 2% token wallet limit (20,000,000,000)
🥩 After 15 minutes, the % max wallet limit is lifted
Fees:
🥩 10% total tax on buy
🥩 Fee on sells is dynamic, relative to price impact, minimum of 10% fee and maximum of 40% fee, with NO SELL LIMIT.
Holders' Benefits
🥩 Every transaction (buy or sell) distributes 6% of the transaction value to the holders.

Rug Relief is a community-driven charitable token that provides reimbursement to members who have experienced rugs, honeypots, and other elaborate scams. People often blame the retail investor for being naive but we believe scammers are 100% of the problem. Media coverage of rampant scams cause investors to shy away from tokens which hurts community growth. The first charitable cause that benefits our own community of investors.
RR Insurance
- Provide full ETH refunds for ALL investors on insured tokens after cost basis calculations
- Token projects would provide initial ETH deposit and a weekly premium to keep the token insured
- Revenue from premiums would be partially vested for operational costs, the rest would pay for cash-injections into the Rug Relief token
RR Tools
- Charting and other trading utility tools developed with improved UI
- Traffic-generating content will be published on the website
- Advertisements will be accepted and provide another revenue stream
💥Tokenomics💥
2% to holders
2% will be allocated into a gnosis safe with the SLINK team as our RR Pool
4% marketing funds
4% will be held for cash injections for long term holders
Marketing + Cash Injections tax will decrease each month to reach total 6% tax in few months.
