A smart contract is required on ETH
45 USD Development of a small smart contract is required.
There will be a donation platform, a person who wants to donate can send any coin in the Ethereum network, the smart contract will pay for gas. (I will fund the smart contract that will cover the gas payment)
A small website with a minimal interface is also needed, where a person can connect their wallet and make a transaction.
In total, a person goes to the website, connects their wallet and, for example, sends 20usdt, while they may not have Ethereum in their account to pay for gas, a third party sees the smart contract paying for gas, and the recipient is a separate wallet.
I have already seen a partially ready solution that will clearly help in the final result at opengsn.org
I am waiting for your price proposals
Client's review of cooperation with freelancer
A smart contract is required on ETHThe time in which it needed to be done, was not done.
I had to google the information myself and prove that he was wrong (in the end, it turned out to be true).
He did not return the $10 that were allocated for the test, meaning he STOLE!
Freelancer's review of cooperation with Letitia Brown
A smart contract is required on ETHThe client cannot formulate a normal technical specification, constantly changing, as a result, the fully working program did not please him because it does not work with the wallet from which money is easily withdrawn.
Also, I did not have the opportunity to read the SMS, so I could not send him his $10, as a result, it turns out he stole it.
I do not recommend working with an unreasonable client.
Here is the transaction hash for the refund to his wallet 0x3a790a6b7e3fb7ec091f9456a0b28f5122b60c558d43aba6bac8feaa2e69ea98
