Four years of secure crypto storage, development continues

The latest version of AirGap (v3.7.0) brings support for BIP-85, Deterministic Entropy From BIP32 Keychains, Tezos Sapling (Edonet only), and cosmos memo addition.


BIP-85 brings solutions to the challenges of having way too many seeds/mnemonics and needing to back them all up securely. It defines a way to derive new mnemonics from a master mnemonic. The benefit of this is that you can have one master mnemonic that you back up properly, and then generate multiple new mnemonics out of it (eg. for different wallets). Without BIP85 you might end up with ten or more different mnemonics that all need backing up.

Over the years, we’ve relied on Changelly and ChangeNOW to serve as our in-built exchange. Both have provided excellent and efficient service to our users.

Simple In-App Exchange

In order to use this feature, you have to enable at least a Tezos account and for example the YOU token.

Early this month, we released AirGap v3.8 with support for WalletConnect. What’s more, guess what? We are going forward at full speed as we add support for Moonriver and integrate QuipuSwap to ensure a seamless swapping experience for all users.

The Sapling WASM library brings the Zcash Rust crates to the web and enables Sapling operations for web applications.

Address, key, and transaction generation

The library handles all relevant Sapling operations, from address creation to transaction signing.

The latest version of AirGap (v3.8.0) introduces WalletConnect, an updated serializer, a simplified onboarding process and support for uUSD and YOU.


WalletConnect is an open-source protocol for connecting decentralized applications to mobile/hardware Wallets utilizing end-to-end encryption and scanning of a QR code. Simply put, if you utilize AirGap in conjunction with the WalletConnect apps, you will be able to perform transactions on platforms without having to transfer all of your funds before doing your transactions. It also lowers the likelihood of a transaction being compromised by private key theft. We will publish a blog about how to use WalletConnect within AirGap soon.

Updated Serializer

To transfer data from one app to another, QR codes are used. Because QR codes have a limited amount…

The latest Beacon SDK version v2.3.0 adds support for the Umami wallet and brings many connection and interface improvements.

Umami — a new Beacon compatible wallet

In this blogpost we will explain what BIP85 is and how it can be used to make managing multiple mnemonics easier and more secure.

What is BIP85

BIP 85 defines a way how new BIP39 mnemonics can be derived from your mnemonic. Put another way, it aids you in deriving “entropy” from your mnemonics, and the entropy you derive can then be used in other wallets and applications. Therefore, it brings the flexibility of managing multiple mnemonics (multiple wallets) while only having to back up one of your mnemonics. If one or more of the derived entropies are compromised, the parent mnemonic and other derived entropies remain secure.

Beacon Network nodes have been moved to a new infrastructure and dApp developers should update to the latest release of the SDK.

The Infrastructure Upgrade

To resolve the degraded performance the decision was made to move the Beacon Nodes to a new infrastructure. The migration was completed on Monday 21st of April at 20:00 CET. After the migration we saw huge improvements in the response time in our tests.
