Smart Contract Consulting

Posted by Willie WittzEnd

Required skills

Hello,
We are a group of retired investors. We have also invested in Crypto and now have a Banking Product we think would be great if done in the Crypto Space. We are looking for Smart Contract Consulting, do an overview of the project, provide a simple write-up on feasibility in respect to the code, see if a simple Smart Contract could be built that would provide the poorest of the poor in the world a Banking Product as well as for people living in first world countries. We are looking at SmartBCH as a platform because we need EXTREMELY low gas fees/transaction fees. SmartBCH uses Solidity and can work just like ETH's ERC-20s. Other platform suggestions are welcomed.
If you can consult with us, look over the concepts that we have and are trying to accomplish (simplified project version), and tell us what can or can't be done using a Smart Contract, as well as educate us, provide simple code examples, we will pay you $400 USD in ETH or in other Crypto for consulting.
Let us know. It could probably take less than a day for you.

Required skills

Hi
I want a dapp, which, user(website visitor) be able to pay the fee(our token generating system which will goes to our wallet + transaction fee which obviously have to be paid to miners) and receive the desired token(token name,symbol,total supply and etc...)
Also me(as the admin of system) be able to set fee of creating that token(even maybe in some times give some discounts for users)
In addition, if you can prepare some contracts which the user be able to select from them and varying fees, it would be better.
some samples are on github, but not exactly what i want.
Also here is a working sample: https://dappbuilder.org/bsc/cappedmintabletoken
