The cyber experts from Wallet.fail have discovered a number of vulnerabilities in the Trezor and Ledger hardware cryptocurrency wallets. As a result, they were able to conduct a series of successful attacks on wallets during the Chaos Communication Congress in Leipzig.

Experts said that the vulnerabilities lie in software and hardware, firmware, software architecture and web interface.

During the demonstration attacks, the Wallet.fail team managed to extract the PIN and mnemonic core from RAM Trezor, remotely sign the transaction and hack the Ledger Nano S loader, as well as intercept the Ledger Blue PIN.

The researchers noted that it is possible to get rid of some vulnerabilities by updating the firmware or replacing microcontrollers.

A leading supplier of Bitcoin and Blockchain solutions, the company Blockstream and Tether have launched USDT in the Liquid Network.

The Blockstream blog says that thanks to this step, ecosystem participants will be able to make fast and secure payments using Confidential Transactions technology, which is oriented towards increased privacy, as well as multi-signature functions. In addition, investors and traders will be able to carry out atomic swaps between Liquid BTC and Stablecoin, and will also be able to replenish their exchange USDT wallets more quickly.

The input and output of Liquid USDt is already available on the Bitfinex exchange. Support for other trading platforms, including BTSE, BTCTrader / BtcTurk, OKEx, OKCoin, RenrenBit and Sideshift AI, will appear soon.

According to the developers, Blockstream Green wallet is suitable for storing Liquid USDt. They also promise to soon add support for the new asset to Trezor hardware wallets.

Tether’s launch on Liquid coincides nicely with the recent surge of interest in the Liquid Swap Tool. The Liquid Swap Tool is an open source application that allows traders to execute atomic swaps with their counterparties, exchanging any Liquid-based asset for another.

In the future, Blockstream and Tether plan to launch USDT tokens on the second-tier Lightning Network.

Liquid is a federated sidecoin of Bitcoin, functioning as a settlement and payment network for cryptocurrency exchanges, market makers, brokers and other financial institutions.

Atomic swaps are the operations of exchanging one cryptocurrency for another, which can be implemented instantly without having to rely on a trustworthy third party represented by the exchange or exchange platform. As a result, control over the transaction is carried out exclusively by the parties involved in it.
