1. Project Objective:
Next-generation cryptocurrency exchange Billium Crypto Exchange plans to create its own blockchain and issue its own cryptocurrency called BILT.
2. Task solution:
It issues an investment token called BEARN (BEA) for this purpose.
3. Solution technology:
The product is for 24 months with guaranteed returns, for a total of 8 periods of 3 months. The process of interest accrual in this product will change step by step: from 1-4 periods the rate is 15%, from 5-8 periods the rate is 7.5%.
Interest payment and the possibility of withdrawal without fee is made during the period of 3 calendar months, further this period is called "transfer window".
Withdrawals outside the transfer window are available at any time, but with a 20% withdrawal fee. The exception is air drop. These tokens will be limited to withdrawal until 31/01/2023.
4. Platform and processes:
Token is a virtual unit of account designed to represent the digital counterpart of a user's investment (payment).
Personal balance is the balance of a user, to which tokens received as income under the terms of a token and available for disposition without restriction are credited.
Internal swap is the user's balance to which tokens are credited upon purchase (it has restrictions on disposition as stipulated herein).
Burn Swap is a balance that displays the number of tokens burned. Unlock of tokens is the process by which tokens in the internal swap become available for disposition.
Transfer window is the period of time in which tokens can be sold without applying a company fee.
The main currency on the project is USDC (TRC20).
The token is created based on TRC20 to interact with TRON-based protocols.
The token issue is 100,000,000 tokens.
The name of the token is BEARN, the acronym is BEA.
The maximum staking period for a token on an internal swap is 24 calendar months.
4.3 Stages of the sale
The sale of tokens should be conducted in stages:
|Stage||Period||Price||Profit||Number of tokens||Number of tokens sold||Transfer window|

The purchase of tokens is available from the start of the Pre-sale stage until 31/07/2024 inclusive.
If tokens provided for a stage are redeemed before the end of the stage, the token sale must be stopped until the next stage in the sequence occurs.
4.4 Time Periods
The following time periods shall be provided:
- Quarterly – from 00:00:00 on the first day of the first month of the calendar quarter to 23:59:59 on the last day of the last month of the calendar quarter;
- Monthly – from 00:00:00 on the first day of the calendar month until 23:59:59 on the last day of the calendar month;
- Daily – from 00:00:00 until 23:59:59 of the calendar day.
Purchased tokens shall be automatically transferred to the staking – internal swap.
The maximum staking period is 24 calendar months from the start of the sale until 31/07/2024
The user can have one staking. Subsequent token purchases or transfer of tokens from the personal balance will increase the balance of the existing staking.
The income shall be calculated at the end of each calendar day based on the number of tokens in the staking. The calculation of income must begin on the day following the day the tokens are credited to the staking, i.e. for the full day the tokens are in the staking.
Staking income should be credited in tokens to the user's personal balance.
Increasing the staking balance by topping up tokens or transferring tokens generated by the staking income is available at any time.
Staking income must be calculated from 01/08/2022. The income for staking is:
- 15% per quarter – from 01/08/2022 to 31/07/2023;
- 7.5% per quarter – from 01/08/2023 to 31/07/2024.
The tokens shall be automatically transferred to the user's personal balance at the end of the staking period.
Example: The user bought 1000 BEA for 1000 USDC on 11/08/2022. He or she should be paid the income for the staking:
- for 08/2022 - (15% / 3 months) / 31 days * 20 days)% * 1000 BEA = 32.25 BEA
- for 08/2022 - 5% * 1000 BEA = 50 BEA
- for 09/2022 - 5% * 1000 BEA = 50 BEA
On 01/10/2022, the user will receive earnings per personal staking balance 132.25 BEA.
4.6 Token selling
The sale of tokens without the application of the company's commission is only carried out during the transfer window.
The transfer window is from the 01st to the 07th day inclusive of the first month of each quarter period.
In case the tokens are not withdrawn during the transfer window, they will be transferred to Staking on the 08th day at 00:00.
During any period other than the transfer window, the sale of tokens is only available with the application of a company fee.
For selling tokens outside the transfer window, a company commission of 20% of the number of tokens sold must be applied.
After the maximum staking period has expired, no commission shall be applied to the tokens sold.
Example: user bought 1000 BEA for 1000 USDT on 05/07/2022. He or she was credited with 132.25 BEA on 01/10/2022. User sold 200 BEA worth 1 USDT on 05/10/2022 and got 200 USDT. Later on 15/10/2022, the user sells another 200 BEA. The user should receive:
- 200 BEA - (200 BEA * 20%) * 1 USDT = 160 USDC.
4.7 Token burning
Burning of tokens shall be carried out in cases of:
- sale of tokens by the user;
- the expiration of token sales on the expired stage (unsold tokens shall be burnt).
4.8 Scheme of interaction between marketing and smart contracts
In order to implement tokenomics, 3 smart contracts need to be developed to handle TRC20-based tokens and interact with the TRON blockchain:
- token_sale – token issuance smart contract;
- staking – a smart contract of staking;
- exchange – exchange smart contract.
The interaction of the project with the smart contracts is done using REST API in order to implement project logic for token buying, token staking and token burning.
