Hello,
I would like to develop a staking website where user can connect with Metamask, have a dashboard where he can see daily rewards .
I want do individualy change the % of the rewards per client depending on the profit I make.
So basacaly I invest the BNB in my project and reward the client with a percentage I make. The client can choose staking time (1 month, 3 Month and 6 Month)
how much would a project like this cost about? nothing fancy...the only individual programming is, that I as an admin can chnage daily the % of the reward. kind regards Mario
Feature Requirements A decentralized exchange on any one of Ethereum Testnets (i.e., Goerli, Ropsten, Rinkby, or Kovan) that supports the following features: • For Asset Issuer: ▫ issue new asset tokens (Only use ERC20 token standard) • For Users: ▫ Submit buy and sell orders (there are many types of order in finance world, for simplicity, try to support limit order first. If time permits, adding supports for other types of order will be bonus points) ▫ Matched orders in the order marketplace will be executed, please noted that an order can be partially fulfilled (e.g., Alice want to sell 10 TokenA for 5 TokenB, whereas Bob only wants to sell 1 TokenB for 2 TokenA, then 20% of Alice’s order will be fulfilled, 100% of Bob’s order will be fully fulfilled.... The smart contract is already built and we just want to add a buying and selling function only
I need a seasoned developer, who has experience with NFT minting and staking, they also need to be able to work with Chainlink VRF. If your only experience is forking other contracts then I will not be interested, this will be need to be built from the ground up, tested audited and fine touched before launch. I will give more details once I have narrowed down the canidates.
Hello. All.
Here is the idea.
We have Algo-bots make profit for sure.
It is well constructed, very safe to operate, generate steady income.
We actually have several bots and all of them generate profit over years.
Now, we want to have a project that raised the fund from users and invest it into trading and pay back interest.
Most of developers that I met suggested me building staking pool, mining pool etc.
Actually, there is too many exists already and most of them ends up with rug-pool.
We want to develop smart contract that can raised the fund from holders at the same time pay interest or reward to holders as they hold the tokens.
We prefer to have no staking involving way.
Buy idea or develop smart contract with idea provider.
Prefer to have BSC based contracts.
Pls reply me cost of work and idea if you have.
I have access to a token on the BSC network where the liquidity is locked on DXsale until 2090.
If you can guide me on how to get it unlocked I will pay you 5K.
This is not a upfront gig as two people have tried and failed.
If you are a genious let me know, it's a good deal.
BEFORE APPLYING, WE NEED TO SEE A PROFESSIONAL SAMPLE REVIEW!!!
SCROLL TO THE BOTTOM WHERE WE PROVIDE INSTRUCTIONS ON WHAT THIS SAMPLE REVIEW NEEDS TO LOOK LIKE
We are looking for an experience developer, familiar with EOSIO/Antelope to conductan open-ended CODE REVIEW for the following repo:
https://github.com/FreeosDAO/freeosgov
We are looking for a code review of these files in the repo:
claim.hpp
config.hpp
constants.hpp
eosio.proton.hpp
freeosgov.cpp
freeosgov.hpp
identity.hpp
maintain.hpp
points.hpp
ratify.hpp
survey.hpp
tables.hpp
vote.hpp
The focus is centred around if you find anything of concern, whether a logic error, inefficiency, security-related, architecturally, etc,
Anything that departs from best practice.
An important aspect is not to concentrate too much on whether the logic is correct - we are QA-ing the code to ensure that. It's best to concentrate on coding practices generally.
NOTE: This is NOT a full, smart contract audit that goes into deeper details (i.e. fuzzing, overflow, DoS attacks etc.).We are looking for an independent 3rd party to review the code as to our focus illustrated above.
The contract documentation can be found here:
https://github.com/FreeosDAO/freeosgov/tree/main/docs
---------------INTERVIEW-SAMPLE-REVIEW-REQUIRED-------------------------
We require some indication of the type of quality we'd like to see and are looking for a small sample review.
Please see the attached points.hpp
Please provide a sample code review—apologies for asking this. We have had very mixed quality when asking for a code review.
Candidates that wish to take this job need to provide a small sample code review of the attached "points.hpp" file to:
1) find 1 issue and identify the location of the issue,
2) provide the severity of the issue, and
3) provide a proposed fix, improvement or best practice for the identified issue
This ONLY needs to be 1 issue in points.hpp for the sample.We don't want to waste anyone's time.
Please provide the sample code review via private message.We will engage with quality candidates that have provided a solid, good sample code review.
We are going to add yield farming feature to our website.
We have two Tokens A,B
