Well, that was fast. ‘Eclair’ – the first Bitcoin (available on Coinbase) wallet supporting the Lightning Network, has been removed from the Google Play store, mere days after being added.

Not long ago, on April 4th, a French tech company called ACINQ added the first mobile wallet that allowed for Bitcoin (available on Coinbase) transactions via the Lightning Network. The app was available through the Google Play store for Android devices fitted with the operating system version 5.0 and higher.

Several days later, on April 7th, the company tweeted they had lost the signing key for the wallet. This essentially means they are unable to update the app.

We just discovered that we may have lost the signing key allowing us to update the app
Note: key isn’t compromised, just was accidentally deleted and isn’t recoverable

This effectively prevents us to patch the app in case of bugs, and we already have suspicion of a bug related to unilateral closing, that we wouldn’t be able to fix if it is confirmed
