AirGap Crypto Storage Platform Now Supports SegWit BTC Addresses »CryptoNinjas

AirGap, a Self-custody wallet for bitcoins and cryptocurrencies with a storage application, announced its latest release today. In the v3.11.0 update, AirGap implemented SegWit support for Bitcoin (BTC), improved secret import and entropy harvesting via dice rolls.

Segregated Witness (SegWit) is an update to the Bitcoin protocol that modified the way data was stored on the blockchain. This update brings several benefits, including greater scalability, faster transaction times, and most importantly, lower transaction fees.

To use SegWit with AirGap, existing BTC users must generate a new address in AirGap Vault and send the funds to the new SegWit address.

Other enhancements include:

Collecting Entropy by Rolling the Dice and Tossing Coins

Secret generation with dice rolls and coin tossing is a safety feature for generating safe mnemonics by using a specific sequence of inputs for entropy. The advantage of this is that users can collect their entropy without any digital help from the built-in RNG (random number generators) device.

On the import page, there is now an advanced switch. Users can choose dice or coin rolls as a way to generate a mnemonic.

New secure mnemonic import function (built-in keyboard)

The AirGap team has now replaced the normal device keyboard with its own virtual keyboard.

This produces advantages such as:

  • The keyboard cannot record / save a mnemonic (some device keyboards do this to check spelling and send everything entered to a server – this is not good for security). The AirGap keyboard does not use external dependencies and is included with the application.
  • The new keyboard allows importing only valid words from the BIP39 list. So there can be no more typos / double spaces etc.
  • The keyboard has BIP39 word completion for faster imports.
  • There is an “encode” button that changes the order of the letters on the keyboard, improving security if someone is looking over your shoulders.
  • There is a “hide” button that masks the mnemonic that has already been entered, improving security if someone looks over their shoulder.

Childhood mnemonic management BIP85

By generating a secondary mnemonic BIP85, it is now possible to directly import that secondary mnemonic as a secret into AirGap. Therefore, users do not have to type it before importing it.

“AirGap’s security features are continually evolving and, in addition to the two new security features mentioned above, we also support the PSBT (BIP-174) standard, which means that the Vault is now compatible with other watch-only wallets, although this it is currently in beta version. “
