I am a swipe.org farm investor. I was a victim when the website was shut down. In the Twitter post, "Our front-end support will end on March 1, 2022. After that, you will need to use smart contracts in Ethereum and BSC to withdraw from Swipe Swap." is located.
But I don't know how to do this. I got back LP tokens in my wallet through smart contracts. But I don't know how to convert LP Token back to USDC-WETH.

I would like to have some enlightment on ERC20 token: If i create a token (let's say MTK ) to be use by a community and i send some of the tokens to each member of the community, does those members have to get ETH in order to use the MTK or they Can use the token whitout the need of having ETH?
I am thinking about using the admin address to get the necessary amount of ETH ( or other ERC20 token compatible crypto currencies) so that if that the that admin account will pay all occuring transactions fees (if needed).Therefore members won't have to deal with ETH and just use the community token.
If it is an ERC20 token on the public mainnet network, someone (else) needs to pay for gas fees executing a transaction, there is no way to circumvent gas costs on L1/mainnet entirely.
What you are looking for are "meta-transactions" or "feeless" transactions: https://ethereum.stackexchange.com/questions/38479/how-to-make-someone-else-pay-for-gas
I have a compromised wallet, where there are bots transferring deposit instantly, so i cant pay fees when trying to move tokens.
I saw a wallet use private transaction with flash-bots for token approvals and other smart contract related functions.
How can i interact with ERC20 tokens and pay fees privately to avoid deposit from being transferred by bots.
so far i have tried using 1inch flash-bots but without ether available i cant access the flash bot option.
Any help will be appreciated
I've been searching for a while, but I can't seem to find an answer to this so it would be very helpful if someone can clarify this 😣.
Let's say i have TokenA as an ERC20 deployed to the Ethereum mainnet and I have TokenB as an SPL deployed in the Solana Blockchain.
Is there any way of exchanging those 2 Tokens?
I know with Uniswap I can create my own pool and put some liquidity for my Token, and then swap it with the Selected pair. Eg. TokenA/ETH
But in the case above, the 2 tokens are part of different Blockchains..
Thank you very much
The sol wallet will be different from the ERC wallet
You can create smart contract for recieve etherium and one for sol
And by the use of molaris server add watcher for event on the 2 contract when one of them recieve the token and the recieve wallet for the other blockchain run script from the molaris server for transfer token for the address from the other blockchain
Sorry for bad English
Everyone can create ethereum token by solidity codes but don't know how can this token integrate as payment gateway in ecommerce website.
For real project . This token need frontend web wallet /android wallet and integration to every website as payment.
Plz suggest me .how can find this way.
What need more to study.
Token is not a payment gateway. If i understand your question correctly, you are asking, how can you interact with a token that you have created through Solidity from frontend. One use case would be how people can use the token that you have created to purchase some item. For this the users should already be holding the tokens. This can be bought from an ICO or from an exchange. Basically there's a couple of functions in ERC20 token i.e., approve() and transfer() that will approve apps like exchanges to perform transactions on behalf of the owner of the token. Once the users have those tokens they can purchase items from it. Again, you have to write the logic how and what you expect users to do.
ERC20 Token is works likes Currency.And solidity is a programming language. which we used for write the smart contract. if you want to invoke your function then you need to create wallet account ,after that you can do transaction using with web3js. you can get ether for testing purpose from faucet.Basically these are functions in ERC20 token i.e., approve() and transfer() that will perform transactions
I don't suggest using ERC20 tokens as payment method.
Ethereum network is not fast enough,you need 30 confirmations to make sure you received the token, some times the delay can be 1 day
Cost is high, when you transfer token ,usually you have a smart contract, it costs lots of gas
Ether price is not stable, it drops 90% of value from Jan 2018 to Dec 2018. it will be hard for estore to maintain profit.
However if you still want to do that, yes, you can create your own gateway using tokens as your accepted currency.
Users can deposit on Binance, for example, various ERC20 tokens, but later then those tokens should be transferred to the Binance cold wallet(wallet used for withdrawing) how those tokens are transferred when the newly generated address doesn't contain any ether(for transferring contracts), it doesn't make any sense for me that Binance sends some ether for every newly generated address.
it doesn't make any sense for me that Binance sends some ether for every newly generated address.
That's exactly what they do. If you do happen to deposit ether, they will leave a little bit ~$5 or so in the address when moving the ether to their cold wallet to pay for future token transactions. If you transfer only tokens, they will transfer some ETH before moving it.
