BEP20 BUSD REFLECTION TOKEN TO COEXIST WITH STAKING REWARDS

Posted by info

Required skills

NOTE: You don't have to go into detail but please explain how you would do so when you message me, I won't reply unless you do so, this way I can filter out the real devs from the bad ones.I will not respond to hello, hi, hey, or anything. I'm looking for a serious dev not some wannabe, thank you.
Please do not reply if you don't know for sure that you can do it, this is not a test. tokens that have done a version of this:
affinitybsc aka safeaffinity: https://bscscan.com/address/0x0cae6c43fe2f43757a767df90cf5054280110f3e#code
earnhub: https://bscscan.com/address/0x80cba4031f7a75b650f4146e5ceba9d7562df939#code(term they named anyflect,state that they are the First Modular Enabled Token, allowing the contract to be upgraded on the blockchain, adding new features like new buy-back systems, auto-balancing staking pools, Play to Earn (P2E) mechanisms, and more.)
both are doing it through it's main contract, token in question is being created right now so if a separate staking contract can't be create in this manner then willing to add code to main contract to allow for these two functions to co-exist.
token: BEP20 BUSD REFLECTION TOKEN
Project requirement:
create a staking smart contract that rewards staking with reflection in tokens based of locked staking period with monthly multiplier,but continues to reward BUSD reflections whiledbeing staked. 
simply stated: as token is staked, continues reflecting BUSD as it was original created but now it will also receive staking rewards (reflected in the token itself), both function co-existing together.

Web app for workshop planing and payment on Juno

Posted by simon

Required skills

I want to build a doodle like DAPP on Juno (cosmosSDK) 
using my own CW20 Token to reserve spots on the "doodle ticketing app'.
Users connect with keplr wallet on Juno network 
User posts a workshop “Trading with 3commas for beginners”
and possible dates like “01.01.2022 16:00,19:00”, “05.01.2022 16:30, 20:00” 
and a minimum amount of CREW token (Juno cw20) 
To launch the workshop, Other users can“stake” their token to specific dates on the event 
If staked CREW for a date is > minimum amount, 
The Workshop willhappens and CREW goes to the creator after the event finishes.
Also it would be nice to have some rating system in place to build a nice 'Professionals Database' with real user ratings.
It would be good if you know some Rust, and know how to do static web apps (PWA would be nice bonus) 
Cheers

Create a new token, UI, and ICO advisory

Posted by Nadim E.

Required skills

I'm looking for a crypto developer to create a new ERC-20 token and the smart contracts associated with it. 
The token acts as a share of an investment fund. The concept is almost identical to Crypto20.com. The difference is the investment fund is actively managed by a fund manager. Funds are invested in several cryptocurrencies/altcoins assets (BTC, ETH, XRP, DOGE, ...).
The fund charges an annual fee accrued daily (or possibly every 8 hours). This is done be issuing new tokens to the fund manager.
The value of the token is based on net assets value of the fund. This needs to be taken into account during deposit and withdrawal.
The important parts that need to be created:
the new token
deposits in ETH in exchange for the new token
withdrawals in ETH from token balance
issuance of new tokens to the fund manager
frontend user interface for deposit/withdrawal
advice and guidance on how to proceed with the ICO
If the budget is too low, we are willing to give tokens as part of the pay.
Please send your proposals including timeline.
