We are excited to announce our collaboration with Edgeware!
Edgeware is a mainnet third generation, self-upgrading smart contract platform in the Polkadot Ecosystem.

On Tuesday 11/03/2021 we signed an agreement with them to develop a Ledger app for Edgeware.

We will start developing the app this week, the functional ledger app is estimated to be finished in 6 weeks. Once the Edgeware Ledger app is finished, it will be submitted to Ledger for their review and approval. Once approved, the app will be available and launched in the Ledger App Store.

Milestone 1: Prototype / Early Integration Release

Zondax Zcash
Zondax Zcash

During the past few months, we have been working on the Zcash app for Ledger Devices (Nano S and X). The Zcash ledger app is a complex technical product, for the devs among us: this is because it involves complex and Zcash-specific cryptography (e.g. ZIP32 and Sapling RedJubJub’s signatures) and workflows (including zero-knowledge proofs) mixed C/Rust implementation and because of the Rust/LLVM non-constant time operations in Cortex-m0.

Milestone 3 completed: what this means

We are very excited to announce that we have released Milestone 3 (out of 4), which means that all source code of the fully functional app is now publicly available on Github.

At times, Polkadot and Kusama users accidentally sent DOTs to Kusama addresses and KSM to Polkadot addresses. By doing so, their transferred funds get blocked in incorrect public keys belonging to a different network. Zondax has developed for Web3foundation a solution so that users can retrieve their blocked funds.

Introducing the DOT Recovery Mode

The DOT Recovery Mode allows users to easily retrieve their blocked DOT (when caused by accidentally sending DOT to a wallet on the wrong network (Kusama) using a ledger device).

The DOT Recovery Mode is operational on Ledger devices.

Sometimes Polkadot and Kusama users accidentally send DOTs to Kusama addresses and KSM to Polkadot addresses. By doing so, their transferred funds get blocked in incorrect addresses belonging to a different network. In the case of purely “browser based keys”, this is immediately recoverable, however, hardware wallets have additional levels of security. For this reason, Ledger apps do not allow signing with cross-chain public keys.

In order to help the community, we are collaborating with multiple stakeholders to develop a solution so that these users can retrieve their blocked funds. The PRs for this recovery mode are already accepted.
