What is Baymax Finance | What is Baymax token | What is BAY token

In this article, we'll discuss information about the Baymax Finance project and BAY token. What is Baymax Finance | What is Baymax token | What is BAY token?

Baymax Finance is a decentralized perpetual contract trading protocol that allows its users to trade with up to 30x leverage. In addition, the platform has a native token, BAY, to enable a robust ecosystem around governance, rewards, and staking to further drive future growth and decentralization of Baymax for a better user experience.

Baymax aims to become the best solution for traders who intend to stay in control of their funds at all times without sharing their data. Its simple but innovative design gives it many advantages over other DEXes.

Enter the world of the next generation of DEX

Real yields: Huge revenue for our protocol will be generated, and it has always been our business to distribute this protocol revenue to our token holders. (Expect even larger revenue with more distribution).
Capital efficiency: Baymax doesn’t require a huge TVL to power all trading needs at optimal trading volume.
Better yields and low risk for liquidity providers: BLP is a really attractive token for liquidity providers simply because it represents and tracks the value of the largest cryptocurrencies. It provides a meaningful hedged position for liquidity providers, where the BLP token gains value (APR) from trading fees accrued. In addition, there will be nearly zero risk for holding BLP as you could redeem for any token in the pool asset anytime.

1. Tokenomics

BAY is the platform's utility and governance token, holding the token unlocks a variety of benefits.

Token Information

Steps to purchase BAY can be found on the Buy page.

After staking BAY, you will receive a staked BAY token. Note that the balance for this will return your total staked amount including any esBAY tokens and Multiplier Points.

Staking

Staked BAY receives three types of rewards:

Escrowed BAY
Multiplier Points
AVAX Rewards

For more info on Escrowed BAY and Multiplier Points, please see the Rewards page.

To stake your BAY tokens, please visit the Earn page.

Supply

The max supply of BAY is 100,000,000.

The increase in circulating supply will vary depending on the number of tokens that get vested, and the number of tokens used for marketing/partnerships.

BAY allocations are:

1. Initial liquidity (20%): 20,000,000 BAY + $50,000. Start price: $0.0025.

2. The remaining 80% BAY will be converted to Escrowed BAY (esBAY) in 2 years:

BayMax NFT (20%): 16,000,000 esBAY (Vesting in 2 years)
Dev Fund (10%): 8,000,000 esBAY (Vesting in 2 years)
BLP Staker (35%): 28,000,000 esBAY (Vesting in 2 years)
BAY & esBAY Staker (15%): 12,000,000 esBAY (Vesting in 2 years)

Fees Distribution

BLP Staker: 60% fees
BAY & esBAY Staker: 30% fees
Buyback & Add liquidity: 8% fees
Gas Fee: 2% fees

Fees collected by the platform are distributed as follows:

2. BLP

BLP consists of an index of assets used for swaps and leverages trading. It can be minted using any index asset and burnt to redeem any index asset. The price for minting and redemption is calculated based on (the total worth of assets in the index including profits and losses of open positions) / (BLP supply).

Holders of the BLP token earn Escrowed BAY rewards and 60% of platform fees distributed in AVAX. Note that the fees distributed are based on the number after deducting referral rewards and the network costs of keepers, keeper costs are usually around 1% of the total fees.

As BLP holders provide liquidity for leverage trading, they will make a profit when leverage traders make a loss and vice versa. Past PnL data, BLP price chart and other stats can be viewed on the Stats page.

Minting and Redeeming

Minting BLP

A list of BLP tokens can be found on the Dashboard.
Fees will be lower for tokens that the pool has less of, check the "Save on Fees" section to get the lowest fees.
Key in the amount of BLP you'd like to purchase on the Buy BLP section of the Buy page.

Fees for buying BLP will vary based on which assets the index has less or more of, the Buy BLP page will show which assets have the lowest fee.

After buying your tokens will automatically be staked and you will start earning Escrowed BAY and AVAX rewards, you can check your rewards on the Earn page.

Rebalancing

The fees to mint BLP, burn BLP, or perform swaps will vary based on whether the action improves the balance of assets or reduces it. For example, if the index has a large percentage of AVAX and a small percentage of USDC, actions that further increase the amount of AVAX the index has will have a high fee while actions that reduce the amount of AVAX the index has will have a low fee.

The token weights can be seen on the Dashboard.

Token weights are adjusted to help hedge BLP holders based on traders' open positions. For example, if a lot of traders are long AVAX, then AVAX would have a higher token weight, if a lot of traders are short, then a higher token weight will be given to stablecoins.

If token prices are increasing, then the price of BLP will increase as well, even if a lot of traders have a long position on the platform. The portion reserved for long positions can be treated as stable in terms of its USD value since if prices increase the profits from that portion will be used to pay traders, and if prices decrease, the losses of traders will keep the USD value of the reserve portion the same.

If a lot of traders are short and larger weights are given to stablecoins. BLP holders would have a synthetic exposure to the tokens being shorted, for example. if AVAX is shorted then the price of BLP will decrease if the price of AVAX decreases, if the price of AVAX increases then the price of BLP will increase from the losses of the short positions.

3. Baymax NFT

Without a doubt, NFTs are a trend. Since the rise in popularity of these digital tokens, many projects have been created to increase their utility. However, these projects usually leave collectors and investors with a useless JPEG.

Here at Baymax, we see the NFT as a source of investment to bring rewards to our users. Thus, the Baymax NFT collection was born to increase the liquidity of Baymax DEX and distribute rewards in AVAX for all NFT stakers.

What is Baymax NFT?

Baymax NFT Collection consists of 10,000 NFTs (non-fungible tokens) living on the Avalanche network. Unlike the other art NFT Collection, Baymax NFT Collection is a collection of utility NFT created for the community to provide more liquidity for Baymax Finance and earn rewards based on the power of NFT.

Baymax NFT utilities

Baymax NFTs are designed to enrich Community Funds, in which all revenue from NFT is spent to reinvest to mint BLP and distribute AVAX rewards for stakers.
Get an additional gift of esBAY for your NFT.
Buy Baymax NFT SOON to get a better price.

The Community Funds are made up of 2 components:

Revenue from selling Baymax NFTs: All revenue generated from the sale of Baymax NFT Collection NFT (minting) goes to the Treasury (see Treasury page) and is invested in BLP to earn the fees charged by the platform.
Accumulated profits from esBAY and AVAX rewards: A portion of BLP revenues will be reinvested in the Treasury to add more BLPs and generate more revenue for NFT holders.

Key benefits of buying Baymax:

Provide liquidity for Baymax for long-term operation of swap and perpetual trading
Earn rewards in AVAX from Protocol’s collected fees according to your total NFT powers
Earn bonus esBAY to stake to earn more rewards or vest to get BAY
The value of community treasury accumulated through time, and with the non-stop fee growth generated, your rewards will be higher after each time of distribution.

4. Trading

Adding a wallet

If you do not have a wallet yet, you can use MetaMask: https://metamask.io/download.html

Connecting your wallet

After you have a wallet, you can connect your wallet by pressing the "Connect Wallet" button on the BayMax Trade page.

If you see the message below, click on "Add Avalanche" to add the Avalanche network to your wallet.

Alternatively, you can manually add the Avalanche network:

https://support.avax.network/en/articles/4626956-how-do-i-set-up-metamask-on-avalanche

Backup RPC URLs

Since BayMax is a decentralized exchange, querying data and submitting transactions go through an RPC URL.

There may be times when the RPC URL is not as responsive as it should be, during these times you may notice data being slow to load or not loading on your page.

For a list of RPC URLs and their statuses: https://chainlist.org/.

Steps to change the RPC URL in MetaMask

Click on the MetaMask icon, then click on the three-dot icon and select Expand View
Click on your account icon on the top right and select Settings
Click on Networks
Key in the New RPC URL
Click Save

Swaps

BayMax supports both swaps and leverages trading. For swaps, click on the "Swap" tab on the Trade page, this will open the interface to swap tokens with zero price impact.

For leverage trading, please see the below sections for more information.

Opening a position

Click on "Long" or "Short" depending on which side you would like to open a leverage position on.

Long position

Earns a profit if the token's price goes up
Makes a loss if the token's price goes down

Short position

Earns a profit if the token's price goes down
Makes a loss if the token's price goes up

After selecting your side, key in the amount you want to pay and the leverage you want to use, in the below example 0.1 ETH worth 141.17 USD is being used to buy a 5x ETH (Ethereum) long position of size 702.35 USD.

The "Entry Price" is $1411.74 and the Liquidation Price is $1156.21. Below the swap box, you would also see the "Exit Price", which is the price that would be used to calculate profits if you open and then immediately close a position. The exit price will change with the price of the token you are longing for or shorting.

The trading fee to open a position is 0.1% of the position size, similarly, there is a 0.1% fee when closing the position.

There is also a "Borrow Fee" that is deducted at the start of every hour. This is the fee paid to the counterparty of your trade. The fee per hour will vary based on utilization, it is calculated as (assets borrowed) / (total assets in the pool) * 0.01%. The "Borrow Fee" for longing or shorting is shown below the swap box.

While there are no price impacts for trades, there can be slippage due to price movements between when your trade transaction is submitted and when it is confirmed on the blockchain. Slippage is the difference between the expected price of the trade and the execution price, this can be customized by clicking on the "..." icon next to your address at the top right of the page.

Managing Positions

After opening a trade, you would be able to view it under your Positions list, you can also click on "Edit" to deposit or withdraw collateral, this allows you to manage your leverage and liquidation price.

When you open a position or deposit collateral, a snapshot of the USD price of your collateral is taken, so e.g. if your collateral is 0.1 ETH and the price of ETH is 1411.74 at the time, then your collateral is 141.17 USD and will not change even if the price of ETH changes.

The amount of profit and loss you make will be proportional to your position size. For example, 141.17 USD has been used to buy 702.35 USD of ETH. If the price of ETH increases by 10%, the position would have a profit of 70.235 USD, if the price of ETH decreases by 10%, the position would have a loss of 70.235 USD.

If a short position was opened instead, then if the price of ETH decreased by 10% the position would have a profit of 70.235 USD, if the price of ETH increased by 10%, the position would have a loss of 70.235 USD.

Leverage for a position is displayed as (position size) / (position collateral). If you'd like to display the leverage as (position size + PnL) / (position collateral), you can customize this by clicking on the "..." button next to your address.

Note that when depositing collateral into a long position, there is a 0.3% swap fee for the conversion of the asset to its USD value, e.g. ETH amount to USD value. This is to prevent deposits from being used as a zero-fee swap. This does not apply to shorts. Withdrawing of collateral from longs and shorts does not have this fee as well.

Closing a Position

You can close a position partially or completely by clicking on the "Close" button.

For long positions, profits are paid in the asset you are longing e.g. if you long ETH you would get your profits as ETH.

For short positions, profits will be paid out in the same stablecoin that you used to open the position, e.g. USDC or USDT.

Stop-Loss / Take-Profit Orders

You can also set stop-loss and take-profit orders by clicking on the "Close" button and selecting the "Trigger" tab.

After creating a trigger order, it will appear in your position's row as well as under the "Orders" tab, you can edit the order and change the trigger price if needed.

If you close a position manually, the associated trigger orders will remain open, you would need to cancel them manually if you do not want the order to be active when opening future positions.

Note that orders are not guaranteed to execute, this can occur in a few situations including but not exclusive to:

The marked price which is an aggregate of exchange prices did not reach the specified price
The specified price was reached but not long enough for it to be executed
No keeper picked up the order for execution

Additionally, trigger orders are market orders and are not guaranteed to execute at the trigger price.

Partial Liquidations

In the example, since only 352.33 USD worth of tokens is used as collateral to open the position, there will be a price at which the loss amount is very close to the collateral amount.

This is the Liquidation Price and is calculated as the price at which the (collateral - losses - borrow fee) is less than 2% of your position's size. If the token's price crosses this point then the position will be automatically closed.

Due to the borrowing fee, your liquidation price will change over time, especially if you use the leverage that is more than 10x and have the position open for more than a few days, so it is important to monitor your liquidation price.

If there is any collateral remaining after deducting losses and fees, then the corresponding amount would be returned to your account.

Pricing

There is no price impact for trades on BayMax, so you can execute large trades exactly at the marked price. During times of high volatility, there will be a spread from the Chainlink price to the median price of reference exchanges.

The mark prices are displayed next to the market name, long positions will be opened at the higher price and closed at the lower price while short positions will be opened at the lower price and closed at the higher price.

The chart will indicate the average of the two mark prices.

Fees

The cost to open/close a position is 0.1% of the position size.

The collateral of long positions is the token being longed, for ETH longs the collateral is ETH and for BTC longs the collateral is BTC, etc. The collateral of shorts positions is in any of the supported stablecoins, for example, USDC, USDT, and DAI. If a swap is needed when opening or closing a position then the regular swap fee would apply, this fee is 0.2% to 0.8% of the collateral size, the exact fee depends on whether the swap improves balance or reduces it.

There is also an execution fee detailed below which is used to pay for the blockchain network costs.

Execution Fee

There are two transactions involved in opening/closing/editing a position:

A user sends the first transaction to request open/close/deposit collateral/withdraw collateral
Keepers observe the blockchain for these requests and then execute them

The cost of the second transaction is displayed in the confirmation box as the "Execution Fee". This network cost is paid to the blockchain network.

Words Counted: A Ruby Natural Language Processor.

WordsCounted

We are all in the gutter, but some of us are looking at the stars.
-- Oscar Wilde

WordsCounted is a Ruby NLP (natural language processor). WordsCounted lets you implement powerful tokensation strategies with a very flexible tokeniser class.

Are you using WordsCounted to do something interesting? Please tell me about it.

Demo

Visit this website for one example of what you can do with WordsCounted.

Features

Out of the box, get the following data from any string or readable file, or URL:
- Token count and unique token count
- Token densities, frequencies, and lengths
- Char count and average chars per token
- The longest tokens and their lengths
- The most frequent tokens and their frequencies.
A flexible way to exclude tokens from the tokeniser. You can pass a string, regexp, symbol, lambda, or an array of any combination of those types for powerful tokenisation strategies.
Pass your own regexp rules to the tokeniser if you prefer. The default regexp filters special characters but keeps hyphens and apostrophes. It also plays nicely with diacritics (UTF and unicode characters): Bayrūt is treated as ["Bayrūt"] and not ["Bayr", "ū", "t"], for example.
Opens and reads files. Pass in a file path or a url instead of a string.

Installation

Add this line to your application's Gemfile:

gem 'words_counted'

And then execute:

$ bundle

Or install it yourself as:

$ gem install words_counted

Usage

Pass in a string or a file path, and an optional filter and/or regexp.

counter = WordsCounted.count(
  "We are all in the gutter, but some of us are looking at the stars."
)

# Using a file
counter = WordsCounted.from_file("path/or/url/to/my/file.txt")

.count and .from_file are convenience methods that take an input, tokenise it, and return an instance of WordsCounted::Counter initialized with the tokens. The WordsCounted::Tokeniser and WordsCounted::Counter classes can be used alone, however.

API

WordsCounted

WordsCounted.count(input, options = {})

Tokenises input and initializes a WordsCounted::Counter object with the resulting tokens.

counter = WordsCounted.count("Hello Beirut!")

Accepts two options: exclude and regexp. See Excluding tokens from the analyser and Passing in a custom regexp respectively.

WordsCounted.from_file(path, options = {})

Reads and tokenises a file, and initializes a WordsCounted::Counter object with the resulting tokens.

counter = WordsCounted.from_file("hello_beirut.txt")

Accepts the same options as .count.

Tokeniser

The tokeniser allows you to tokenise text in a variety of ways. You can pass in your own rules for tokenisation, and apply a powerful filter with any combination of rules as long as they can boil down into a lambda.

Out of the box the tokeniser includes only alpha chars. Hyphenated tokens and tokens with apostrophes are considered a single token.

#tokenise([pattern: TOKEN_REGEXP, exclude: nil])

tokeniser = WordsCounted::Tokeniser.new("Hello Beirut!").tokenise

# With `exclude`
tokeniser = WordsCounted::Tokeniser.new("Hello Beirut!").tokenise(exclude: "hello")

# With `pattern`
tokeniser = WordsCounted::Tokeniser.new("I <3 Beirut!").tokenise(pattern: /[a-z]/i)

See Excluding tokens from the analyser and Passing in a custom regexp for more information.

Counter

The WordsCounted::Counter class allows you to collect various statistics from an array of tokens.

#token_count

Returns the token count of a given string.

counter.token_count #=> 15

#token_frequency

Returns a sorted (unstable) two-dimensional array where each element is a token and its frequency. The array is sorted by frequency in descending order.

counter.token_frequency

[
  ["the", 2],
  ["are", 2],
  ["we",  1],
  # ...
  ["all", 1]
]

#most_frequent_tokens

Returns a hash where each key-value pair is a token and its frequency.

counter.most_frequent_tokens

{ "are" => 2, "the" => 2 }

#token_lengths

Returns a sorted (unstable) two-dimentional array where each element contains a token and its length. The array is sorted by length in descending order.

counter.token_lengths

[
  ["looking", 7],
  ["gutter",  6],
  ["stars",   5],
  # ...
  ["in",      2]
]

#longest_tokens

Returns a hash where each key-value pair is a token and its length.

counter.longest_tokens

{ "looking" => 7 }

#token_density([ precision: 2 ])

Returns a sorted (unstable) two-dimentional array where each element contains a token and its density as a float, rounded to a precision of two. The array is sorted by density in descending order. It accepts a precision argument, which must be a float.

counter.token_density

[
  ["are",     0.13],
  ["the",     0.13],
  ["but",     0.07 ],
  # ...
  ["we",      0.07 ]
]

#char_count

Returns the char count of tokens.

counter.char_count #=> 76

#average_chars_per_token([ precision: 2 ])

Returns the average char count per token rounded to two decimal places. Accepts a precision argument which defaults to two. Precision must be a float.

counter.average_chars_per_token #=> 4

#uniq_token_count

Returns the number of unique tokens.

counter.uniq_token_count #=> 13

Excluding tokens from the tokeniser

You can exclude anything you want from the input by passing the exclude option. The exclude option accepts a variety of filters and is extremely flexible.

A space-delimited string. The filter will normalise the string.
A regular expression.
A lambda.
A symbol that names a predicate method. For example :odd?.
An array of any combination of the above.

tokeniser =
  WordsCounted::Tokeniser.new(
    "Magnificent! That was magnificent, Trevor."
  )

# Using a string
tokeniser.tokenise(exclude: "was magnificent")
# => ["that", "trevor"]

# Using a regular expression
tokeniser.tokenise(exclude: /trevor/)
# => ["magnificent", "that", "was", "magnificent"]

# Using a lambda
tokeniser.tokenise(exclude: ->(t) { t.length < 4 })
# => ["magnificent", "that", "magnificent", "trevor"]

# Using symbol
tokeniser = WordsCounted::Tokeniser.new("Hello! محمد")
tokeniser.tokenise(exclude: :ascii_only?)
# => ["محمد"]

# Using an array
tokeniser = WordsCounted::Tokeniser.new(
  "Hello! اسماءنا هي محمد، كارولينا، سامي، وداني"
)
tokeniser.tokenise(
  exclude: [:ascii_only?, /محمد/, ->(t) { t.length > 6}, "و"]
)
# => ["هي", "سامي", "وداني"]

Passing in a custom regexp

The default regexp accounts for letters, hyphenated tokens, and apostrophes. This means twenty-one is treated as one token. So is Mohamad's.

/[\p{Alpha}\-']+/

You can pass your own criteria as a Ruby regular expression to split your string as desired.

For example, if you wanted to include numbers, you can override the regular expression:

counter = WordsCounted.count("Numbers 1, 2, and 3", pattern: /[\p{Alnum}\-']+/)
counter.tokens
#=> ["numbers", "1", "2", "and", "3"]

Opening and reading files

Use the from_file method to open files. from_file accepts the same options as .count. The file path can be a URL.

counter = WordsCounted.from_file("url/or/path/to/file.text")

Gotchas

A hyphen used in leu of an em or en dash will form part of the token. This affects the tokeniser algorithm.

counter = WordsCounted.count("How do you do?-you are well, I see.")
counter.token_frequency

[
  ["do",   2],
  ["how",  1],
  ["you",  1],
  ["-you", 1], # WTF, mate!
  ["are",  1],
  # ...
]

In this example -you and you are separate tokens. Also, the tokeniser does not include numbers by default. Remember that you can pass your own regular expression if the default behaviour does not fit your needs.

A note on case sensitivity

The program will normalise (downcase) all incoming strings for consistency and filters.

Roadmap

Ability to open URLs

def self.from_url
  # open url and send string here after removing html
end

#tokenise([pattern: TOKEN_REGEXP, exclude: nil])

tokeniser = WordsCounted::Tokeniser.new("Hello Beirut!").tokenise

# With `exclude`
tokeniser = WordsCounted::Tokeniser.new("Hello Beirut!").tokenise(exclude: "hello")

# With `pattern`
tokeniser = WordsCounted::Tokeniser.new("I <3 Beirut!").tokenise(pattern: /[a-z]/i)

See Excluding tokens from the analyser and Passing in a custom regexp for more information.

Counter

The WordsCounted::Counter class allows you to collect various statistics from an array of tokens.

#token_count

Returns the token count of a given string.

counter.token_count #=> 15

#token_frequency

Returns a sorted (unstable) two-dimensional array where each element is a token and its frequency. The array is sorted by frequency in descending order.

counter.token_frequency

[
  ["the", 2],
  ["are", 2],
  ["we",  1],
  # ...
  ["all", 1]
]

#most_frequent_tokens

Returns a hash where each key-value pair is a token and its frequency.

counter.most_frequent_tokens

{ "are" => 2, "the" => 2 }

#token_lengths

Returns a sorted (unstable) two-dimentional array where each element contains a token and its length. The array is sorted by length in descending order.

counter.token_lengths

[
  ["looking", 7],
  ["gutter",  6],
  ["stars",   5],
  # ...
  ["in",      2]
]

#longest_tokens

Returns a hash where each key-value pair is a token and its length.

counter.longest_tokens

{ "looking" => 7 }

#token_density([ precision: 2 ])

counter.token_density

[
  ["are",     0.13],
  ["the",     0.13],
  ["but",     0.07 ],
  # ...
  ["we",      0.07 ]
]

#char_count

Returns the char count of tokens.

counter.char_count #=> 76

#average_chars_per_token([ precision: 2 ])

Returns the average char count per token rounded to two decimal places. Accepts a precision argument which defaults to two. Precision must be a float.

counter.average_chars_per_token #=> 4

#uniq_token_count

Returns the number of unique tokens.

counter.uniq_token_count #=> 13

Excluding tokens from the tokeniser

You can exclude anything you want from the input by passing the exclude option. The exclude option accepts a variety of filters and is extremely flexible.

A space-delimited string. The filter will normalise the string.
A regular expression.
A lambda.
A symbol that names a predicate method. For example :odd?.
An array of any combination of the above.

tokeniser =
  WordsCounted::Tokeniser.new(
    "Magnificent! That was magnificent, Trevor."
  )

# Using a string
tokeniser.tokenise(exclude: "was magnificent")
# => ["that", "trevor"]

# Using a regular expression
tokeniser.tokenise(exclude: /trevor/)
# => ["magnificent", "that", "was", "magnificent"]

# Using a lambda
tokeniser.tokenise(exclude: ->(t) { t.length < 4 })
# => ["magnificent", "that", "magnificent", "trevor"]

# Using symbol
tokeniser = WordsCounted::Tokeniser.new("Hello! محمد")
tokeniser.tokenise(exclude: :ascii_only?)
# => ["محمد"]

# Using an array
tokeniser = WordsCounted::Tokeniser.new(
  "Hello! اسماءنا هي محمد، كارولينا، سامي، وداني"
)
tokeniser.tokenise(
  exclude: [:ascii_only?, /محمد/, ->(t) { t.length > 6}, "و"]
)
# => ["هي", "سامي", "وداني"]

Passing in a custom regexp

The default regexp accounts for letters, hyphenated tokens, and apostrophes. This means twenty-one is treated as one token. So is Mohamad's.

/[\p{Alpha}\-']+/

You can pass your own criteria as a Ruby regular expression to split your string as desired.

For example, if you wanted to include numbers, you can override the regular expression:

counter = WordsCounted.count("Numbers 1, 2, and 3", pattern: /[\p{Alnum}\-']+/)
counter.tokens
#=> ["numbers", "1", "2", "and", "3"]

Opening and reading files

Use the from_file method to open files. from_file accepts the same options as .count. The file path can be a URL.

counter = WordsCounted.from_file("url/or/path/to/file.text")

Gotchas

A hyphen used in leu of an em or en dash will form part of the token. This affects the tokeniser algorithm.

counter = WordsCounted.count("How do you do?-you are well, I see.")
counter.token_frequency

[
  ["do",   2],
  ["how",  1],
  ["you",  1],
  ["-you", 1], # WTF, mate!
  ["are",  1],
  # ...
]

A note on case sensitivity

The program will normalise (downcase) all incoming strings for consistency and filters.

Roadmap

Ability to open URLs

def self.from_url
  # open url and send string here after removing html
end

SafeMoon Clone | Create A DeFi Token Like SafeMoon | DeFi token like SafeMoon

SafeMoon is a decentralized finance (DeFi) token. This token consists of RFI tokenomics and auto-liquidity generating protocol. A DeFi token like SafeMoon has reached the mainstream standards under the Binance Smart Chain. Its success and popularity have been immense, thus, making the majority of the business firms adopt this style of cryptocurrency as an alternative.

A DeFi token like SafeMoon is almost similar to the other crypto-token, but the only difference being that it charges a 10% transaction fee from the users who sell their tokens, in which 5% of the fee is distributed to the remaining SafeMoon owners. This feature rewards the owners for holding onto their tokens.
