Today, let's talk about how to use smart contract functionality on Qtum Electrum. Write your own smart contract in two easy steps.

In short, if you are looking for a Bitcoin wallet, then you must try Electrum.

Many wallets do not currently support custom fees, which can cost users a lot of fees. I strongly recommend waiting a while when there are more transactions in the memory pool, and then transfer your currency to an address where you can customize the fee. You can Google which wallets support custom fees, currently electrum and Bitcoin.

In December 2018, Slow Fog first discovered and alerted an attacker to a messaging flaw using the Electrum wallet client, forcing an "update prompt" to pop up when a user transfers money, inducing the user to update and download the malware, which in turn commits a currency theft attack. Although electrum officials said in early 2019 that some security mechanisms would be in place to prevent this "update phishing", many users of Electrum are still in the old version (less than 3.3.4) and the old version is still under threat. However, we do not rule out a similar threat to the new version.

"The initial version has BCH and BTC, and by integrating elements from BTC Electrum into BCH Electron Cash - other Bitcoin-compatible coins can be added later, such as litecoin, dash, doge, etc.," the developer explains in detail.

Dash Electrum 3.2.3.1 was released, renamed Dash-Electrum, adding the option to use Tor Proxy at startup, according to Dash Coin. DASH is now trading at $159, down 3.26 percent.

In this demo, Electrum developer Chris Belcher shows how to set up and use an Electrum personal server.

Bitcoin wallet Electrum official Twitter announced that the next version of Electrum will support Lightning online payments. Its lightning node implementation has been consolidated into the main branch of Electrum. Electrum also confirmed that the wallet will adopt a new implementation of in-house development written using Python.

All of our data is stored on the primary server. If the server crashes, we're done. If Twitter crashes, we can't tweet. If Facebook crashes, well, it's enough to crash haha.

A single address can only make one pledge transaction, so the address wants to make a second pledge transaction, need to cancel the previous pledge.
