There are five categories of Ethereum wallets that can interact with dApps
Browser built-in (Opera, Brave, ...)
Browser extension (MetaMask, ...)
Mobile wallets (Trust, Walleth, Pillar, ...)
Account-based web wallets (Fortmatic, 3box, ...)
Hardware wallets (Ledger, Trezor, ...)
Then there is a larger category of wallets that cannot integrate with dApps ...
What are the chances that 2 people get the same set of those 12 or 24-word mnemonic?
Mnemonic phrases are generated from 128 bits (12 words) to 256 bits (24 words) of entropy. The probability to guess a mnemonic phrase is 2^-128 to 2^-256, which is very small. The longer the mnemonic phrase, the smaller the chance to guess it though.
Is it possible to ...
My understanding is that the launchpad was made to be as user-friendly as possible, including for users who are less CLI-proficient. In the interests of making things as streamlined as possible, various options were not included. If you would like to research a more manual method for connecting to Medalla (using Geth, for example), the information you need ...
You can run MyCrypto's desktop application fully offline, and sign transactions from your offline computer too. The application is fully open-source and available on GitHub here. There are instructions for compiling your own version if you'd like. Running it offline does not require a Geth node or any sort of hardware (except for a computer, of course). You ...
There are no "wallet aliases" in Ethereum. Sounds like you came up with this term yourself.
It is not possible to avoid paying gas and somebody needs to pay for it. Ethereum network is public infrastructure and its security is supported by the transaction fees. There are some other blockchains, like EOS, which offer limited free tier transactions ...
Go to your tempkeys folder. You'll need to be root, become root with sudo su - and when you're done with all the steps, logout with logout
The file in there is known as your keystore.json, copy that file. This is an encrypted version of your nodes private key.
Import it into your wallet of choice, and you can unlock it with the password you locked it with. ...
If an Ethereum wallet address was created using MetaMask
It doesn't appear so, at least during creation. (You can verify this by watching for network traffic during the creation process.)
can the IP address of the wallet's owner be logged or uncovered somehow?
By default Metamask uses Infura. When submitting transactions, traffic routed via Infura will ...
Yes and no.
Ethereum wallets are more versatile what you seem to have. MetaMask predates Web3authn, so it has the first mover advantage. The different "wallet providers" provide different ways to connect a wallet and sigh the transaction. For example, WalletConnect wallets connect by a scanning a QR code and you sign the transaction using a mobile push ...
To send tokens you call the transfer function of the contract. This is done by sending a transaction with a value of 0 ETH to the token contract, with transaction data containing the function identifier, address to send the tokens to and the number of tokens to send. This is done through your own wallet.
Note that transfer and Transfer are two different ...
No, I don't know how you imagined this, but as long as a user has
the private key
the ETH still on the account
Nothing can stop him from spending his ETH. So whatever you do, locking ETH can only happen if ETH is transferred, be it to an escrow contract or maybe an off-chain multisig EOA.
Before Metamask v7, the wallet extension was sharing the user selected address with every opened tabs. That means, any websites opened through these tabs could possibly track the user's transactions history and the amount of ethers/tokens held by the wallet. A malicious website could simulate the Metamask behavior by sending the user fake pop-up/...
If you used the Ethereum geth client, then the key information required to access the accounts was in the folder "keystore". If you have lost this data, then it is impossible to restore access to the accounts.
In addition, there are some curated lists of tokens that you can submit your token to. Applications, such as wallets, pull tokens from these curated lists.
Token Curated List of Tokens https://tokens.kleros.io
(https://uniswap.ninja/ pulls token list from here, for example. This one is a decentralized list, meaning everyone maintains it, not just a curator.)...
b, welcome to Ethreum's Stack Exchange.
To my knowledge, there's no implementation of withdrawing your Ethers out of the Chainlink Node's wallet, but the accounts are generated with Geth's Go library , so in theory you could copy that folder and import the accounts using a local Geth node. There you would have full access to your funds.
Also, the Geth'...
The owner of a specific token can maintain a "blacklist" in the context of his token's contract. In relation to the whole Ethereum, the implementation of this is unlikely, if only due to the absence of a owner from the public Ephereum.
In my opinion you're missing a key concept: decentralization.
There is no official anything. There is no official website. There is no official wallet or software or anything. It's a decentralized network where everyone can build whatever tools they want.
Yes, the Ethereum Foundation has a website (which isn't the best) but it's just one of the million ...
Maybe it is because in Coinbase's web interface when an exchange executes, in reality, there is no interaction at all with related blockchains. the onsite exchange is just happening on Coinbase's database, while withdrawals are the ones that are really being processed on the related blockchain.
Just to clear up the non-speculative parts of your question:
...there is no actual decentralized application that you can install and run,...
Of the listed wallets, MyCrypto and MyEtherWallet certainly have standalone, non-browser, non-browser-extension packages that you can download and run offline (air-gapped, if you wish), and which will generate you a ...
Using keystore files (and private keys, mnemonic phrases, etc.) on websites is discouraged because there's a higher risk of them being stolen. The DNS servers of the website could be hacked (which happened multiple times on MEW), or you could be on a fake website without realising it.
A relatively safe way to use keystore files is through MyCrypto's desktop ...
You can mine Ethereum using geth
Install geth on your pc then create an account using "geth account new" , then simply just run geth with --mine option then it will start mining the ether and all the earned ether will be sent to the account generated
Note:- As the ether mainnet is using POW you require a very powerful pc high best graphic card
Your best bet may be to use Noah Zinsmeister's web3-react. It is fully customizable and will let you achieve all of your goals.
Another alternative is Blocknative's Onboard achieves what you want. Their interface is relatively customizable.
Integration is very similar to that of the options you have tried so far.
Instead of deterministic payment addresses, you might want to use a smart contract for the payment.
There is only a single smart contract (address) where the payments go in (you can also deploy multiple contracts e.g. one per store, but this is a different question)
Each payment comes with a reference message in the Data field
Smart contract can ...
Ethereum commonly uses m/44'/60'/0'/0/0, but you can use other derivation paths. Using a BIP-49 or BIP-84 (segwit) derivation path works just like normal, assuming that you have an application that can derive Ethereum addresses from one of those paths. In the end, you still have a normal Ethereum address where you can send ETH to.
First, you are not querying the right endpoint. If you want to fetch ERC-20 events, you must do the following query :
Notice that unfortunately, the input field ...
The Ethereum Wallet you are using is the Mist application. The work on this application ended on March 22, 2019.
The error you are seeing is probably due to the fact that the application has not been updated with the latest Ethereum changes.
You can look into https://app.gitbook.com/@arkane/s/widget/
Arkane allows you to easily integrate your app with several blockchains, whether you already have an app integrated with web3 or are building a new application from scratch.
To answer your question directly, the wallets you mentioned are a convenient way for the Medalla Launchpad to allow you to send Goerli ETH to the deposit contract.
The Medalla launchpad helps you send Goerli ETH to the deposit contract. This means that you need a wallet (interface), such as MetaMask, Authereum, Portis, etc.
Geth is client software (written ...
