This library was forked from breadwallet-core and was originally designed for BTC. There are enough differences where it could be optimized for LTC and even dynamic algorithms that take advantage of a user with more or fewer wallet addresses. The Bloom filter implementation is set at a default and make be improved.

Testing the Slack hook

Overview

We are resurrecting the effort to have Litewallet Android to have bech32 support. If you recall, we wanted to have bech32 for both iOS and Android a few years ago.

We have a working solution in the production version of Litewallet iOS in that it accepts and sends to bech32 addresses. bech32 origination/wallet is in the future.

For Litewallet Android, we were unable to upgrade as it would have destroyed tens of thousands of users Litewallet databases on older devices and they would lose access to their Litecoin. This would be very bad.

Current Approach

Recently we upgraded the Litewallet Android code which uses newer versions of Android OS and by default the older devices would be unable to upgrade yet the presumption is they would still have access to the pre v2.6.1 versions of Litewallet.

This effort will try to test the previous work against the latest version of Litewallet and we will scope the negatively affected prior to rollout.

The classes that used testnet BTC have different derivation schemes and they need to be refactored to testnet LTC

Problem

When migrating the loafwallet-core to bech32 there is a class and method that remaps the memory spacing. Older phones cannot take the updates because the mapping causes the database to lose the data.

Goal

Ugrade the library loafwallet-core so that older phones like Samsung J2 and Samsung J7 can manage the onboard database given the newer memory mapping.

Bounty

We are offering $500 for this bug fix in Litecoin. We are non-profit and this is quite alot for our budget but it will help thousands of users.

I'm looking at implementing the Breadwallet-Core into my cryptocurrency's wallet. I was wondering what adaptations have been made so that Loafwallet can become compatible with the Litecoin network. Any algorithm changes?

Overview

Allow the Android Java layer to update the false positives to change the BloomFilter prior to syncing.
