The transaction has already been processed and it's final. If the wallet doesn't support the token natively, you can simply contact the crypto.com customer support to ask what could be done about it. …

Yes, tokens are simple ledgers with some transfer functionalities. … They are used to represent some things: typically something completely new (gaming tokens, voting tokens, utility tokens) or sometimes representing a real-world asset (a share of a house, a part of a painting …

There can typically be any number of different tokens on a blockchain but only one cryptocurrency. In the Ethereum ecosystem tokens are created with smart contracts. … Token standards Often when someone mentions "Ethereum tokens" they are actually referring to ERC-20 standard compatible tokens. …

For example if you currently control all the tokens, you can transfer all the tokens to a void address (typically address 0x0 is used) and after that the tokens are useless and therefore the contract is … If other people own tokens then you can only try to get the tokens from them and then render the contract useless. …

Mostly because the contract isn't aware of any trading patterns or prices - it simply transfers tokens when asked to. …

As you can't iterate over the balances mapping in ERC20 token contract you have to go through emitted events and filter those. This is not a nice or trivial task and includes some heavy processing - t …

Your contract is relying on a password, which is set in the constructor. The password variable field is marked as private. Nothing in Ethereum is private. All data is public. Using a contract variable …

The following two functions caught my attention: // Absorb any tokens that have been sent to this contract into the pool function gulp(address token) external _logs_ _lock_ … internal { bool xfer = IERC20(erc20).transfer(to, amount); require(xfer, "ERR_ERC20_FALSE"); } I'm not exactly sure what they do but in theory they could be used to assign the tokens …

Well, since you didn't provide high enough of a gas price miners don't mine the transactions. So you can either wait or replace the transaction. (I don't know how replacing a transaction works in Remi …

You don't need to "find" a smart contract which does that, since there isn't probably a token which does exactly what you need. So you need to create it. Most of your requirements sound like pretty st …

If they are in Kraken's wallet, you have to ask them. So contact Kraken customer service to find out whether they can be retrieved. Unfortunately, there's a big chance that they can't be recovered.

As you said, you can't really have secrets in the contract. Except if some data is encrypted off-the-blockchain and the result sent to the contract. The problem with that approach is the work that ne …

I assume they organized an ICO and the minimum limit was not reached? In any case, if the contract doesn't include any refund options (automatically or manually) then your only option is to contact th …

You have misunderstood how tokens work (and exchanges). When you create a smart contract for a token, the contract contains all the tokens. Then you can send the tokens somewhere. … If you get your token listed in any (centralized) exchange it's a huge thing already. 99,99% of tokens do not get listed I'd guess. …

I'd like to point out two things: 1) Yes, the price is volatile currently. But most likely it will stabilizie in the future. 2) In some scifi minds there is no need for fiat in the future as you can …
