The word light-wallet or light-client can mean a number of things. There is the fast-sync'd versions of geth and parity which reduce the amount of data necessary on your hard drive.
There are also wallets available that have their own node infrastructure that you can use without syncing the chain:
You can change the node MEW ...
The passphrase mechanism is accurately described in BIP 39
How Ethereum keys are derived is described here
These mechanisms are common for Ethereum and other cryptocurrency wallets.
Jaxx offers something called an HD or Hierarchical Deterministic wallet which uses your initial seed to generate new addresses each time you make a transaction. This is designed to increase privacy and was inspired by Bitcoin but creates a few usability quirks with the Ethereum account model and also tokens in Jaxx.
Either way you can always see your exact ...
Can I suggest you read about key management? Generally speaking the private keys for most crypto currencies (if not all), are valid across the board.
However, wallet implementations differ because the addressing part of the respective chains is different, and wallet implementations do not in every case imply downloading the blockchain.
In addition ...
Using a multisig wallet contract requires that each address that was registered as a co-owner is able to call the wallet contract validate method.
Jaxx only supports ether transfer from an address to another but doesn't support contract method interactions. For now you have to use mist or any software that can interact with contracts as Geth or any other ...
Is a Light-wallet
If you are nosy, you can try out the latest nightly build of Parity and run:
To play around with the experimental light client. If you just want to use your parity wallet from a remote device, you can run a server or workstation with:
parity --public-node --ui-interface <public ip>
Where public IP is either your ...
I don't think it's possible NOT to have any transaction fees. Like centralized apps (paypal, etc.) you need transaction fees to cover for maintenance for their servers. With Ethereum and other blockchain and decentralized application you need these fees to give out to those "miners" who compute the next blockchain (think of it as a tip). But compared to ...
MyEtherWallet is able to do this. It can access an account based on the private key only, e.g. the "Send Ether & Tokens" or the "View Wallet Info" tabs. Select "Private Key" as the access method. It is off-line and safe if used according the the instructions - you can download the code from GitHub and run it locally if you are extra-cautious.
You can export your JAXX private key and import it in MyEtherWallet to work around limitations in JAXX user interface:
You need the token contract address and number of decimals.
The company doing the ICO should provide you with this info. If not, you can search for the token on Etherscan. You can also find it by inspecting your transaction on Etherscan.
Here is a picture that shows you what to do once you have gotten hold of the contract address and amount of decimals (...
If the transaction failed, then no ether was transferred. You can't recover what you spent on gas (~$0.03), but nothing happened to the rest of the ether.
If Jaxx thinks the ether is gone, then that's a bug in Jaxx. As you can see, your balance is still ~13 ETH: https://etherscan.io/address/0x7d22b18d2a9f97a2d20bfcc079acd9c18bf93fa4.
Internal transactions, despite the name "aren't actual transactions", and aren't included directly in the blockchain; they are value transfers that were initiated by executing a smart contract (smart contract ETH transfer).
BitStamp ETH transfers require calling a smart contract to perform the transfer. These show up as internal transactions and are not ...
Try entering the mnemonic here: https://iancoleman.io/bip39/, and set the "coin" to "ETH - Ethereum". Then flip through the "derived addresses."
I downloaded the Jaxx Chrome extension and generated a wallet. For me, the first derived address from iancoleman.io/bip39 for that mnemonic matched the address that Jaxx gave me. Hopefully, one of the addresses ...
Logically it is not possible since you have to pay gas fee in order to deploy your transaction. Basically each transaction has a base cost of 21,000 Gas, for the transfer of funds. In your wallet, it is always safe to keep your %1 of your fund always ready to cover up transaction fees.
The questions could be who will cover the cost. There are some exchanges (...
I have the exact same problem as the currency balance was not updating the last few days. I did the reset and now it shows zero as the currency balance, but I can see the amount of ETH.
I submitted a support request to Jaxx but they have not yet answered. Seems this is a problem across Jaxx and not just for one user.
Did you check the words you wrote down by re-entering the phrase into the phone at the time you made the copy? Otherwise, you might have made the same mistake several times (less problematic with BIP39 passphrases than alphanumeric codes where 1s and ls, 0s and Os look similar, but still possible). You should have 12 English words as part of your phrase. If ...
Tap the "Refresh" button twice and then the "Jaxx" Logo twice. The Ethereum wallet icon will appear beside the bitcoin one.
Bonus: Go to settings to set the Ethereum wallet as the default selection when opening the app.
1.Get a trusted friend/android emulator to install Jaxx on his device.
2. Tell him to install this app https://play.google.com/store/apps/details?id=com.lenovo.anyshare.gps&hl=en to share the APK with you.
It is definitely not a secure way and can expose you to various attack vectors. But it will work.
My main concern was not being able to access the DAO tokens I purchased with ETH from my Jaxx wallet. I opened Jaxx today and there is a new, DAO tab which has my tokens! Do no need to import into Mist to access my DAO. Great job Jaxx!
