The strongest foundation of all has always been community.
SaninTama – Also the Shiba Inu Killer from the Saitama,
that is a decentralized experiment that intends to employ a community with the collective goal of solid organic growth.
DeFi has become a repetitive cycle of pumps and dumps, and it’s hard to find a trustworthy project with a dedicated team.
SaninTama emphasizes financial security.
The fate of the project will be decided upon by the community. Welcome to SaninTama!

Pomer Token
Community-focused, decentralized cryptocurrency with yieldfarming rewards for holders.
Pomeranian harnesses the power of Blockchain to evolve cryptocurrency. Our ecosystem consists of decentralized finance-based apps such as Decentralized Exchange, Staking, Decentralized Asset Marketplace (NFTs and Pomeranian Assets), Finance Gaming and others to come. Pomeranian Coin (PMR) is our Utility Token used as Governance Token in the Pomeranian ecosystem and as an internal currency for the overall ecosystem.
Unlimited supply
There is no limit to the number of Pomer tokens that can be minted through a contract on the platform
Predetermined price
The buy and sell price of Pomer tokens increases and decreases with the number of tokens minted and burned, respectively
Instant liquidity
Tokens can be bought or sold instantaneously at any time, the bonding curve acts as an automated market maker
Pomeranian Coin (PMR)
Pomeranian is the ERC-20 utility token accepted across the Pomeranian finance platform. Here, token is mostly used for to trade (Buy and Sell) NFT assets, grants rewards to those who staked their Pomer tokens into the staking pool, and available for swap within Pomeranian decentralized exchange.
Pomeranian harnesses the power of Blockchain to evolve crypto currency. Our ecosystem consists of decentralized finance-based apps such as Decentralized Exchange, Staking, Decentralized Asset Marketplace (NFTs and Pomer Assets), Finance Gaming and others to come. Pomeranian Coin (PMR) is our Utility Token used as Governance Token in the Pomeranian ecosystem and as an internal currency for the overall ecosystem.
In the Pomeranian IBCO when you buy a token, each subsequent buyer will have to pay a slightly higher price for each POMER token. As more individuals are interested in the project and start investing in the POMER token, the value of each token progressively increases along the bonding curve. This gives you the first-mover advantage.
The cost of each POMER token is settled by the bonding curve which depends on the total supply of the token and reserve ratio, and whatever Ethereum is paid into the curve or contract to buy Pomer token, this is deposited or stored in the BCO.
Pomeranian NFT (Pomeranian Assets)
1. Alpha Pomeranian Asset [Alpha NFT]
Alpha is the most dangerous type of Pomeranian. When in canine form they are noticeably larger. Alphas have bright Red eyes. In rare cases, Alphas can literately turn into actual wolves, but in a larger and more brutish appearance. Alphas are the ones that can create new Pomeranians, or other new shape-shifters. An Alpha’s eyes glow red when shape-shifted. An Alpha Pomeranian carries an internal spark of power that supplements their ability to shape-shift, making it easier for them to shift into more powerful shapes, as well as their individual strength and supernatural abilities.
On Pomeranian Platform Alpha Pomeranian will own a territory. So total number of Alpha on the platform will be equal to total number of territories exists on the planet.
An Alpha Pomeranian NFT is having some additional characteristics like Power Absorption, Empathy, Pain Transference, Mind Melding, Full Moon Power Enhancement, Super memory, Super Intelligence, Resistance to cold, Telepathy and Silver Damage %.
2) Beta Pomeranian Asset [Beta NFT]
Beta Pomeranians are members of a Pomeranian pack, following the leadership of an Alpha Pomeranian. Betas are bound to the pack they belong to Although not as powerful as an Alpha, Beta Pomeranians are noticeably stronger than Omega Pomeranians. Betas are the main members of the pack. Betas are the most common Pomeranian type. They are the standard canine shape-shifter. In a pack, most members will be betas, with the leaders being the alphas. A beta shape-shifter’s eyes will glow bright Gold.
On Pomeranian Platform when Beta Pomeranian born in specific territory that Beta will be assigned to the Alpha Pomeranian of that territory by default. Each such territory will contain many Beta Pomeranians with same Alpha Pomeranian as their leader.
Similar to an Alpha Pomeranian NFT, a Beta NFT is having some common characteristics like Healing, Strength, Speed, Vision, Senses, Transformation Time, Agility, Wolsbane Resistance etc.
Beta Pomeranian NFT also have some additional characteristics like Superhuman Stamina, Superhuman Endurance, Superhuman Dexterity, Pain Absorption, Extraordinary Superhuman Leaping, Infectious, Resistance to cold, Rage Enhancement.
3) Omega Pomeranian Asset [Omega NFT]
Omegas are the lowest rank in the canine shape-shifter hierarchy. These wolves are not members in a pack, or have no affiliation with an alpha or an experienced beta. An omega shape-shifter’s eyes will glow Blue. Omegas are generally the lowest on the power level, because they are not members of a pack, of which members gradually receive symbiotic balance, power from each other. Omegas could be the survivor of a pack’s destruction, or they could be alone by their own choice. Because they are considered to be “The Outcasts”, Omegas are searching for a pack. Despite being the weakest and lowest-ranking Pomeranians of the lycanthrope, Omega Pomeranians are still strong and powerful creatures in their own right.
Unlike Beta Pomeranian When an Omega Pomeranian is born in a specific territory then by default it won’t be assigned to the Alpha Pomeranian of that territory.
Omega Pomeranian NFT are the lone Pomer. They are having less characteristics/power than an Alpha or Beta Pomeranian NFT, although they share common characteristics like Healing, Strength, Speed, Vision, Senses, Transformation Time, Agility, Wolsbane Resistance with both of them.

//! Inheritable "property" contract that enables methods to be protected by

//! Usage: use modifiers onlyowner (just own owned) or onlymanyowners(hash),
//! whereby the same hash must be provided by some number (specified in
//! constructor) of the set of owners (specified in the constructor, modifiable)
//! before the interior is executed.

* This implementation is agnostic to the way tokens are created. This means

*
* 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}.

/**
* @dev computes e ^ (x / FIXED_1) * FIXED_1
* input range: 0 <= x <= OPT_EXP_MAX_VAL - 1
* auto-generated via 'PrintFunctionOptimalExp.py'
* Detailed description:
* - Rewrite the input as a sum of binary exponents and a single residual r, as small as possible
* - The exponentiation of each binary exponent is given (pre-calculated)
* - The exponentiation of r is calculated via Taylor series for e^x, where x = r
* - The exponentiation of the input is calculated by multiplying the intermediate results above
* - For example: e^5.521692859 = e^(4 + 1 + 0.5 + 0.021692859) = e^4 * e^1 * e^0.5 * e^0.021692859

* 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}
