Description

In order for BDK to extend beyond just a Bitcoin wallet, it needs a more powerful descriptor capability. This project aims at improving the descriptors used in the library. Currently BDK uses only a single descriptor for a single wallet. Giving a new descriptor to BDK will create a brand new wallet.

The goal of this project is to create a wallet that can handle multiple descriptors within itself (a "super wallet"), and can send funds from any or all of them together.

Expected Outcomes

• Through understanding of descriptors.
• Basic understanding of the rust-miniscript library.
• Multi descriptor capability in BDK.
