Smart Contract Needs Withdraw Function Written

Posted by Anonymous

Required skills

We are an Ethereum NFT project that a dev bailed on and called transfer of ownership over to the community. We have a communal wallet and the transfer of ownership has been confirmed. We have had a few mints and there is eth sitting in the contract. We simply need a withdraw function written into the smart contract so mints automatically transfer from contract to our wallet whenever we have a mint -- or a withdraw function that allows us to easily pull the eth from the contract after a few mints -- whichever is easier.

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.
