Disposing of "dust attack" UTXOs

In a recent collaboration offer, the development and enhancement of the ddust tool, a project aimed at identifying and addressing the issue of dust-sized Unspent Transaction Outputs (UTXOs) in Bitcoin wallets, was discussed. This tool is particularly useful for wallets defined by public key descriptors and is compatible with hardware signers capable of signing a Partially Signed Bitcoin Transaction (PSBT), although extensive testing with such signers has yet to be conducted.

The current focus is on refining the process for combining unconfirmed dust disposal transactions, marking it as an initial step towards improving the tool’s functionality. Interested collaborators are encouraged to start by compiling and experimenting with the ddust project using a regtest bitcoind node available at this GitHub repository. Further, it's recommended to familiarize oneself with the bdk_wallet and bdk_bitcoind_rpc Rust crates, accessible via crates.io and crates.io respectively, as these components significantly contribute to the project's underlying operations.
